The plastic window does not close: possible causes and solution to the problem. Why a plastic window does not close: the main causes of breakdowns and methods for eliminating them The plastic window closes what to do

Plastic windows irreplaceable thing in every house. They are practical, comfortable, beautiful and easy to use. But sometimes problems arise with them too. It happens that it doesn't close plastic window. But most often you can solve this problem yourself without the help of a specialist.

Reasons for not closing a plastic window

The main reasons for the breakdown of plastic windows are either incorrect installation and operation, or in low-quality material. But if nothing can be done about the product, then the first problem is easy to deal with.

To begin with, it is important to ensure that the installation is carried out in accordance with the requirements and instructions, and you also need to operate the window correctly.

If over time it stops closing, there is nothing terrible about it, it’s just that any product requires more and more careful care over time.

There are reasons why windows may not close:

1. Sagging of the sash causes it to cling to the frame and prevent the window from closing completely.
2. The sash flies off the top fastening and is held only by the lower one.
3. The handle does not turn completely, turns with difficulty and creaks, and gets stuck in one position.
4. Remains small space between the sash and the window, which leads to incomplete closure.
5. Mechanism loosening.
6. Blocking the drainage strip.

All these reasons lead to window breakage, but are quite easy to fix with your own hands.

What to do if the plastic window does not close

1. To do this, you need to remove them decorative coating and find in the top and bottom end sides loops special gaps.
2. They can be made for a hex or Phillips screwdriver.
3. Each adjustment screw should be slightly tightened. by 1-2 mm, this is usually enough.

Then you need to close and open the window, if the problem goes away and it is completely closed, then everything was done correctly.

If the sash falls off the fastening

This problem arises due to the fact that when closing the window, the sash is not pressed tightly and the mechanism seems to remain in the middle position between “full opening” and “ventilation”. This indicates that the window was not closed correctly. The fix is ​​very simple.

It is enough to turn the handle parallel to the window sill, press the sash tightly against the frame and lower the handle down. Now try to open the window in both positions.

But here’s what to do if, with such a maneuver, the problem remains unresolved and top corner moved away? The reason for this is the “scissors” flying out of the grooves.

You can restore them in the following way:

• turn the handle up if you cannot press the blocker towards you and repeat the rotation;
• at this moment you need to monitor the movements of the “scissors” while rotating the handle;
• adjust the condition of the “scissors” so that they fit into the grooves intended for them without any problems;
• release the blocker and check if the handle works.

Sometimes, to carry out such a procedure, the sash needs to be removed from its hinges. To do this, you need to remove the plastic covers and press the hinge pin with a tool. But this measure is not always necessary.

Handle jamming

Sometimes the handle of a plastic window does not turn completely or turns with difficulty and does not reach the final destination, and sometimes it even stops in one position. This happens due to a malfunction of the blocker located at the bottom of the closing block.

It is necessary to press down the blocker and turn the handle up, then press on the upper edge of the window and lower the handle, close the sash. Open it again and check if it is working properly.

What to do if the problem remains? Sometimes this problem can also arise due to drying out of the internal mechanism. Lubricating it is quite simple; for this purpose there are special holes on the sides and top of the sash. But it is best to lubricate them with silicone oil or machine oil.

Under no circumstances should you add alcohol or acetone, as well as butter or Vaseline, as this will only worsen the problem.

Window not closing completely

Everything here is pretty basic. And the problem is not in the mechanism, but in the operation. If, when closing the window, you do not press it tightly against the frame and at the same time turn the handle, then it may slip past the grooves, thereby leaving a small space. The conclusion suggests itself - press the window tighter When closing there will be no problem.

What else can be done to make plastic windows close tighter? Also, the reason for a loose fit of the sash may be eccentric position.

These are special devices on both edges of the sash, which are adjusted to the “Summer” and “Winter” modes.

In the first case, the pressure is less dense than in the second. To fix this, just turn them 90˚ using a hexagon or pliers and then the sash will fit snugly against the frame.

The handle does not turn

Sometimes the mechanism begins to hold weakly due to the fittings not mating with the rod, and then it becomes almost impossible to control the handle. This can be corrected by tightening the fasteners.

To do this, you need to rotate the plug located at the base of the window handle 90 degrees. Behind it there will be two screws, which need to be tightened tightly using a screwdriver (Phillips or regular).

Next, the plug returns to its original position. If after this the problem does not disappear, then the handle will have to be replaced with a new one. To do this, just unscrew its screws and insert other new handles in their place.

The key to long-term operation of plastic windows

If you follow simple precautions when using plastic windows, they will serve you much longer, and you will have to call a professional much less often.

For this it is important:

1. Window installation must be carried out by specially trained people, according to the instructions.
2. You need to buy double-glazed windows only from trusted companies that you trust.
3. When closing the window, do not apply much pressure to the handle so as not to damage its mechanism.
4. Do not hang things (clothes, curtains, bedspreads) on the open door.
5. Once a year, carry out a preventive inspection for damage to the mechanism and lubricate its components.
6. Try not to cause mechanical damage (scratches, dents, impacts, cracks).
7. Give the mechanism a rest. When open for a long time, the hinges place a large load on them, so it is not recommended to keep the window “ventilated” long time.
8. Make sure that dust and dirt do not get into the mechanism (especially during repairs) and carry out cleaning in a timely manner.
9. If the window is closed for a long time (usually winter period), sometimes you need to open it for a second so that the mechanism does not stagnate.

If you follow all the above tips, plastic windows will serve you for decades.

And although it’s quite easy to fix minor damage yourself, remember that if the window is under warranty, it’s better to call a specialist. In this case, you can save your effort and money (repairs are free under warranty) and save your purchase from more trouble if you are not an expert in repair matters.

The situation when a plastic window does not close or closes with jamming may be caused by for various reasons. And in each individual case there is a simple way to solve the problem. Let's find out what to do if the window does not close or is difficult to close.

Common problems with plastic double-glazed windows

Problems with operation plastic double glazed windows, in addition to temporary jamming, can be caused by several reasons. Knowing them, you can eliminate the main problem with your own hands - difficulties with closing the sash.

Illustration	Cause of poor closing
	Distortion relative to the sash to the frame - The problem is eliminated by adjusting the glass unit vertically or horizontally.
	Hardware failure- the problem is solved by replacing, repairing or preventive maintenance of fittings.
	Fittings clogged with dust- the problem can be solved by cleaning and lubricating the fittings.
	Deformation plastic frame when walls shrink- the problem is solved by changing the position of the clamping bar or changing the trunnion setting mode.

Repairing double opening

During operation of the window, it happens that it immediately opens in two positions and seems to hang on one hinge. I offer two simple instructions, how to close a window if it does not close.

The first method is relevant for double-glazed windows with Siegenia fittings (the handle is located on the left and the hinges on the right).

Illustration	Description of actions
	Removing the handle lock. Using the finger of your left hand, press and hold the double opening latch.
	Press the top corner. With our right hand we press the sash against the frame near the top hinge.
	We fix the sash in open form . Holding the double opening lock with your left hand, turn the handle to the horizontal position.
	Closing the sash. We release the latch, close the sash and you can move the handle to the down position.

The second method is relevant if the window does not tilt normally on the GU fittings (the hinges are located on the left and the handle on the right).

Illustration	Description of actions
	Make sure that GU fittings are installed on the glass unit. The corresponding mark can be seen on the end of the sash.
	Freeing the handle. Index finger right hand press the double opening latch.
	Pressing the corner of the sash. With your left hand, press the sash against the frame in the area of ​​the upper left hinge. Turn the handle. After the upper part has given way forward, lower it and turn the handle to the horizontal position with your left hand.
	Release the double opening latch and close the window. All you have to do is turn the knob down and the problem is solved.

Eliminating rubbing of the sash against the striker plate

This instruction will be of interest to many, since rubbing of the sash appears on any door, regardless of the profile brand and the brand of fittings. Rubbing sooner or later occurs due to the fact that the sash sags under its own weight.

How to close a window that does not close due to overwriting? The fittings need to be adjusted.

Illustration	Description of actions
	Finding the top loop. To do this, open the window and inspect the corner opposite the place where the sash rubs against the frame.
	Installing the key. Before adjusting the hinge, insert a 4 mm star key or 4 mm hex key into the adjustment hole from the corner.
	Adjusting the loop. We turn the key clockwise half a turn and immediately check the position of the sash relative to the frame.
	Checking the result of the adjustment. As a result of the adjustment, the window should close freely without the slightest rubbing, both from above and from below.

Eliminate jamming of the handle when closing

A common problem that many people encounter is that the handle is jammed when the window is closed, and it does not go down completely. That is, the handle does not turn after 2/3 of its stroke and rests against something.

Many owners of double-glazed windows, faced with the fact that the handle does not turn, continue to use it loosely closed window, despite the fact that it blows, and there is much more noise from the street than before.

Meanwhile, the problem can be solved very simply.

Illustration	Description of actions
	Determining the cause of jamming. To do this, open the door. We clamp the double opening latch and turn the handle vertically down. If the handle is vertical, then the problem is not in the sash, but in the frame.
	We determine which clamp limits the movement of the trunnion. To do this, unscrew the clamps from the frame one by one. The clamps are attached to self-tapping screws, which will require a shaped screwdriver to remove. Unscrewing the clamp, we try to close the window. When the window closes properly, you will find that clamp that is a hindrance. The removed clamps must be installed in their original position.
	Twist the clamp. If one clamp interferes with closing, it needs to be unscrewed from its original place and screwed a couple of millimeters lower. In this case, the pin will fit freely into the groove and the problem will be solved.
	Changing the mode on the trunnion. Sometimes the frame itself has a slight curvature. And therefore, the clamp that is located on the curvature will touch the axle more strongly than the other clamps. In this case, use a 4 mm hexagon to turn the cam of the trunnion with a mark from the clamp. As a result, the pin will fit better and the handle will stop wedging.

We looked at a way to eliminate jamming of the handle by twisting one clamp. But it may be that the interference is caused not by one clamp, but by all clamps on one side of the frame, most often on the rear. What to do in this case?

Adjusting the sash relative to the clamps

In order to adjust the window relative to the clamps, it is not necessary to remove the sash from its hinges. It is enough to find access to the upper and lower hinges and, by simple adjustment, move the sash 1-2 mm towards the clamps. As a result, all trunnions will fit into the groove more freely.

Illustration	Description of actions
	Setting up the top loop. We insert a 4 mm wrench into the adjusting screw and turn it clockwise so that the sash moves towards the hinges. Due to this, the trunnions will fit behind the clamps more freely, and the handle will unlock.
	Setting up the bottom loop. The lower loop is adjusted in the same way as the upper one. Moreover, the settings are performed synchronously so that there is no skew. At the top and bottom, unscrew the adjusting screws clockwise half a turn at a time. And we check whether the trunnions fit behind the clamps or not.

Hardware repair

The previous instructions showed how to fix a handle that jams due to a mismatch between the clamp and the trunnion. But there are situations when the window does not close well due to hardware problems.

Illustration	Description of actions
	Determining the cause of jamming. To do this, open the sash, clamp the double opening latch and at the same time try to lower the handle to the vertical down position. If, when the latch is pressed, the handle does not exit the ventilation mode, the reason is a problem with the fittings.
	Lubricate the fittings. First, we try to eliminate the jamming through lubrication. The easiest way to do this is to spray WD-40 into each longitudinal hole along which the axle runs.
	We define problem area on fittings. If the lubricant does not help, lower the handle as far as possible and inspect the trunnions around the perimeter of the sash. The situation will most likely be the following - all the trunnions will not be moved completely, but one will be completely moved. This problem is caused by the fact that the mechanism has slipped during operation and rests, while the rest of the trunnions still have free play.
	We analyze the problem area. To do this, unscrew the screws that hold the problematic part of the fittings.
	We release the stuck pin. We set the trunnions around the perimeter of the sash to the “open” mode. We disconnect the edge of the fittings and remove the “male” lock from the “female” one.
	Aligning the location of the problematic trunnion. Now that the stuck pin is not held by the latch, it can be moved from the extreme position to the central one, that is, in the same way as all the pins are located.
	Closing the latch. We insert the “male” latch into the “male” until a characteristic click is heard. After this, you need to check whether the handle works or not.	When ordering windows, do not skimp on fittings. If a window manufacturer offers several types of fittings to choose from, this is not at all a reason to choose the one that costs less. Choose something that is more expensive and of higher quality, because the fittings determine how the window will be used.
	Carry out preventive cleaning and lubrication of fittings annually. To do this, use a thick, long-haired brush to sweep away all the dust from the fittings. Then, into all technological holes, the usual machine oil or squeak eliminating fluid VD-40. Immediately after this, turn the handle up and down several times to disperse the lubricant. Excess lubricant is wiped off with ordinary rags.
	Once a year, inspect the sash for distortion.. To do this, along the line of the vestibule, a perimeter is drawn with a pencil. Next, the window opens and the distance of the perimeter from the frame opening is measured with a ruler. The difference should not be more than 1-2 mm. The window needs to be adjusted without waiting for it to completely hang and wear out.

Let's sum it up

I talked about all the reasons why a window might be blocked, and now you know how to close a double-glazed window. If you have questions during unlocking, ask them in the comments to the instructions. In addition, I recommend watching the video in this article, I’m sure you will find it interesting.

A situation often arises when an installed plastic window stops closing. What to do in this case? It turns out that there is no need to call a specialist and pay for his services. It is quite possible to make all the adjustments yourself. Today we’ll try to figure out what to do if the plastic window doesn’t close, and we’ll also look at other possible problems and methods for eliminating them. It also makes sense to know how to maintain, prevent and adjust locking mechanisms.

Plastic windows have long been firmly established in our lives.

There can be quite a lot of small problems. And most often, they are all quite simply solved by simple adjustments. Less often, windows require replacement. The main malfunctions can be called:

• The sash is skewed and does not fit tightly to the frame;
• Handle jamming in different positions;
• Opening the sash simultaneously for ventilation and swinging open;
• Handle loosening;
• Blocking the drainage strip.

Good to know! The listed malfunctions can be avoided if timely prevention is carried out. It is also very important how qualified the workers will be to install the windows. It is worth reading reviews about a particular company in more detail.

We will deal with the listed faults and methods for adjusting and repairing plastic windows.

Repair of plastic windows when the sash is skewed

A common cause is improper installation and initial adjustment. To fix this you will need a hex wrench (usually #4). Here you need to understand that the top hinge of the sash is responsible for adjusting the window left and right, relative to the frame, and the bottom hinge is responsible for adjusting the window up and down. If the sash is skewed, it needs to be corrected urgently. Otherwise, damage to the double-glazed window itself, which is not cheap, may occur.

Adjustment is also possible by placing special spacers between the frame and the glass unit - to do this you will have to remove the glazing beads. The work is carried out with the sash open, with periodic checks - the sash closes smoothly, and you can immediately see whether the repair has been completed or not.

Loose fit of the sash to the frame is the most common reason

This can happen if plastic windows are not switched to winter mode after a warm period. This is not difficult to do. Having opened the window, you should carefully examine the locking mechanism - there should be a corresponding mark on it. Usually, to switch the mode, you need to turn the central valve using a hexagon. After this, you need to close the window by pressing a sheet of paper with it. If everything is done correctly, the paper will not be pulled out.

How to open a plastic window if the handle is jammed

The blocker is most often to blame for this problem. This is a device that fixes locking mechanism in certain positions. If the windows are used for a long time, it may not work in the desired position. Most often this happens when the handle is turned to the “closed” state while the window is open. To fix it, you need to bring the sash into a vertical position, after which the handle should turn. If this does not happen, most likely you will have to change the locking mechanism.

It may also happen that the handle jams when it is not turned completely. The cause of this problem can be either clogging of the mechanism or drying out of the lubricant. In the second case, everything is solved quite simply - stores now have a large assortment various sprays. The best option will use silicone lubricant. If the mechanism is clogged, it must be disassembled and cleaned.

Important! When disassembling the locking mechanism, you need to remember the sequence of installation of the parts. If there is little hope for memory and attentiveness, it is better to seek help from specialists.

If the mechanism is jammed and the plastic window does not open (what to do), the video instructions will help you figure it out.

The sash opened for ventilation and swinging open at the same time

The reason for this may not be a malfunction, but simple carelessness when opening. The problem is easily resolved. The handle turns upward, and the sash must be pressed tightly against the frame with your hand. When it is in place, lower the handle all the way down. Such actions should not cause any difficulties.

All modern plastic windows are equipped with locks that prevent such situations, but excessive haste when opening may prevent it from working. You should not try to open the sash when the handle is not in the desired position - this will save you from many problems.

Repairing plastic windows with your own hands when the handle comes loose

This problem can easily be solved on your own. To do this, you need to turn the handle base bar clockwise. There will be two screws under it that need to be tightened. If they are torn off, you will have to replace the handle completely, choosing a suitable one in the store.

In general, setting up plastic windows with your own hands is not difficult. It is only necessary to fully understand the design of the locking mechanism. The very design of plastic windows various models differs slightly.

What to do if the handle does not turn

In this case, you will have to disassemble the locking mechanism. The cause may be debris and foreign objects getting between the parts. If necessary, faulty parts are replaced with new ones. It is better to entrust such work to specialists. Otherwise, there is a high risk that the mechanism will have to be completely condemned.

Blocking the drainage strip - what does it mean?

Such a malfunction does not require any o special knowledge and skills to correct it. What to do if the plastic window does not close this reason? The answer is very simple: you need to open the sash and simply adjust it so that it does not interfere.

Prevention of malfunctions of plastic windows

To extend the service life of a plastic window, periodic maintenance should be carried out. Be sure to lubricate all parts of the locking mechanisms. Also, the adjustment of the sashes plays quite a role. important role: it increases the durability of the rubber bands that provide a tight seal and reduces the risk of needing and repair of plastic window fittings.

Before production of periodic pro Lactic, you should study the technical documentation as carefully as possible plastic products and their locking mechanisms, so as not to aggravate the malfunction instead of preventing it.

The nuances of repairing or replacing accessories

Most often, parts of window fittings that have become unusable cannot be repaired and require replacement. In this case, it is very important to pay attention to the weight of the window sash itself - this will be decisive when purchasing hinges or a locking mechanism. The fittings may fit perfectly in size, but if they are designed for less weight, such a replacement will not be of any use.

The design of the window is also important - it determines which parts will fit and which will not.

Important information! If the replacement is rotary folding mechanism for a plastic window is not urgent and you can get by with some adjustments; there is no need to rush into purchasing. The later the repair is made, the longer the spare parts will last. It should be understood that original parts very often turn out to be of much higher quality than those purchased separately.

Lubricating parts of the locking mechanism and hinges

Most convenient about lubricate the locking and tilt-and-turn mechanisms of plastic windows with special lubricants Azka-sprays, the range of which on store shelves is quite wide. Such sprays penetrate perfectly between moving and rubbing parts. It is recommended to carry out this work at least two to three times a year.

But at least once a year it is necessary not only to lubricate, but also to clean the mechanisms from the old substance. It is where all the dirt and dust collects, which over time renders the parts unusable. But before production similar work it is necessary to study in detail the device, which is quite complex and if subsequent installation is incorrect, it will simply stop working.

When using plastic windows, do not underestimate the importance of preventative maintenance. After all, if their age is not small, there is no guarantee that if any part fails, it will be possible to find a similar one. Otherwise, you have to change the entire mechanism and it is not a fact that this will succeed. Or the entire window needs to be replaced, which can make a decent hole in family budget. That is why you should listen carefully to the sounds that accompany the opening and closing of the sash. If a metallic grinding noise occurs, it is necessary to urgently lubricate and clean the parts.

Adjustment is also required periodically. Don’t forget about switching seasonal modes - this will significantly extend the service life of plastic windows.

High-quality ventilation is also very important - it does not allow condensation to accumulate on the windows. IN winter time it can turn into ice on the profile, which has a detrimental effect on it. This advice also includes the fact that heating radiators should be located under the window to remove excess moisture.

What to do if you can’t fix the problem yourself

Not all malfunctions can be dealt with on your own. Very often a plastic window does not open due to a jammed handle and the problem cannot be solved with your own hands. In this case, the help of a specialist is needed. But if the windows in the apartment were installed recently, then a company that respects itself and the client should have there is a guarantee. Then there is no need to look for a specialist outside.

Well, if the warranty service has already expired, you can look for specialists on the Internet. But it is worth remembering that you need to study customer reviews about a particular company as carefully as possible. After all, you don’t want to pay a lot of money for outright hack work. Indeed, in this case, it may turn out the same way as one of the Internet users.

Summarizing

Surely it became clear to everyone that it is better to carry out periodic maintenance yourself than to face serious problems that require the help of a specialist. After all, if you follow all the instructions specified in technical documentation, adjustment and lubrication will not cause any special difficulties. But the fact that these actions significantly extend the service life of windows is an indisputable fact.

We hope that the information presented was useful to our dear reader. If you have questions, you can always ask them in the discussions.

Nowadays it is very difficult to imagine any building without a plastic window. This type of window is firmly rooted in Everyday life. However, if it is already quite “old”, that is, it was installed back in the days of the first generations of such windows (8-10 years ago), and also if you are the owner of handicraft windows, some problems may periodically arise in the form of one or another type of breakdowns.

So, we will talk about the reasons why a plastic window does not close, as well as ways to fix the problem in this article.

Causes of breakdowns: main types

Let's look at the main problems that may arise with plastic window fittings.

Sagging flaps

The problem is the sash sagging

This problem is most often typical for massive wide sashes that open either very often or extremely rarely.

The reason for this problem is the misadjustment of the hinges on which the entire system of “opening and closing” the window rests.

Eliminate this problem not difficult with my own hands. It is enough to adjust the system. To do this, you just need to remove from the hinges decorative overlays, find holes for a screwdriver on the hinges (it can be of any type - hexagonal, Phillips or standard screwdriver) and tighten each of the holes on each hinge. If you do everything correctly, the window will open and close freely again.

The sash is held on the bottom hinge

This is what good hinges look like

This happens when the window opens in two positions at once, and the handle is blocked, preventing it from returning to its original position. This is possible if you turn the handle completely to the open position and pull the sash towards you.

The mechanism does not have time to move to the final position, and the sash remains held only on the lower hinge.

What to do in such a situation?

First you need to unlock the handle. To do this, you need to find a so-called blocker at the end of the sash, which is always a spring element.

It is necessary to press the lock and, holding it in this position, move the handle to the “open” position up. Then, while continuing to hold the lock, press the upper corner of the sash against the frame and move the handle down to the “closed” position. The problem will be resolved. To avoid such sagging in the future, you need to ensure that during subsequent openings the sash is pressed tightly against the frame until you move the handle to the desired position.

The handle is locked in the folding position - what should I do?

Adjusting the fastening of bolts

If the handle on your plastic window does not close, this may mean that an element called “scissors” has fallen out of the grooves.

This element is located at the top of the sash and is attached to the hinge. To fix the problem, it is best to remove the sash from its hinges and place it out of the frame; this will make repairs more convenient and safer. To remove the sash from its hinges, you need to remove decorative fittings, squeeze the pins out of the loops and remove them using pliers or wire cutters.

After removing the sash, inspect its upper part and find the “scissors”. To see how they fell out of the grooves, you need to press the spring lock on the handle and try to turn it to one of the positions. At the same time, you will find grooves on top from which the “scissors” fell out.

At this point it will become clear where exactly they need to be set. If you did everything correctly, the handle will rotate to any position freely. Having eliminated the problem, insert the sash back into the frame, installing it in the hinges on the pins, and hammering them back.

Blocking the sash with any object

For example, this item could be a protective drainage strip, which is installed by some manufacturers with outside window. You need to inspect the window from the outside. If in the lower part you see a narrow bar that has shifted from a symmetrical position somewhere to the side, then you just need to move it back into place so that it takes its original position.

What to do if the problem persists?

If you have tried the tips described above, but your plastic window still does not close, then you should not test its strength further.

There is no need to forcefully press on the sash, as this could result in the hardware breaking or the glass or frame falling out completely inward or outward (and this is dangerous for injury, because such a window weighs quite a lot - from 20 to 120 kilograms!). If the handle does not turn, do not force it trying to turn it will 100% lead to permanent failure. It is better to seek the help of professionals, especially if the warranty is still valid. In any case, the help of a specialist will cost you much less than having to change the fittings or the window completely!

If the window does not close - possible reasons and troubleshooting methods

Greetings. This time you will learn about what to do if a plastic window does not close and how to prevent such problems. The topic of the article is of particular interest after approximately 5 years of operation of double-glazed windows in a PVC profile.

Of course, you can contact the organization where the windows were ordered for troubleshooting, but the price professional services high, and you can deal with these problems yourself.

The main reasons for poor narthex

The most common reason for the unsatisfactory operation of the locking mechanism is sagging of the fittings and, as a result, sagging of the sash. As a result, all elements of the locking mechanism are displaced in vertical plane relative to each other and the window does not close tightly.

A less common cause is the pins sticking inside the locking system. This problem occurs in those double-glazed windows where manual control and automatic closing are used. The problem is eliminated by disassembling the locking mechanism and then debugging it.

Another reason is the visor with outside shifted towards the vestibule and did not allow the sash to come close to the frame.

Now that we know why the window does not close, let's look at the listed problems on specific examples and find out how to fix such problems yourself.

Setting up fittings to correct sash misalignment

If the sash does not close well, namely one of the sides hits the frame, then the structure is sagging and needs to be leveled in a horizontal or vertical plane.

Let me point out right away that there are many different brands accessories, which may differ in their own way appearance, degree of reliability and price. But all window fittings, which is used on double-glazed windows, works on a similar principle and is equally regulated.

Instructions for adjusting the window sash in the horizontal and vertical plane to eliminate interference are as follows:

• First, close the sash - if it sags, just lift it a little on one side;

• After the sash is covered, we mark the junction of the sash with the frame, namely, with a pencil we draw a dotted line along the perimeter of the narthex;

• Open the sash and measure the distance from the dotted line to the outer edge of the frame opening;

If the distance around the entire perimeter is the same, then the cause of the problem is not the sagging of the fittings, but something else. If the discrepancy between the distances around the perimeter is more than 2 mm, then adjustment is necessary. By the way, optimal distance the distance the sash should fit onto the frame is 5-7 mm.

• With the sash open, inspect the top hinge for the presence of adjustment screws (the screws are located either on the side or on top of the hinge);
• After the adjusting screw has been found, insert the appropriate key into it (5 mm hexagonal asterisk);

• By turning the key clockwise, you can move the sash towards the hinges, and if you turn the screw counterclockwise, the sash will move away from the hinges;
• Next, we find the bottom loop and, using a screwdriver or tip, carefully remove the plastic casing from it;

• From the upper end of the lower loop we find a hole and insert the key into it;
• By turning the key clockwise you can raise the sash, and by turning it counterclockwise you can lower it;

Adjustment by clockwise and counterclockwise rotation may differ depending on the brand of windows.

• You can also use a lower screw on the lower hinge, which performs actions similar to the adjustment on the upper hinge, that is, you can move the sash left and right in the horizontal plane.

After all the adjustment screws are adjusted, the perimeter of the sash should be at the same distance from the outer perimeter of the opening. If you succeed, then the adjustment was completed successfully and the window will close without jamming.

What to do if the handle does not turn all the way

Now let's consider a very common phenomenon, namely, the case when the handle of a plastic window does not close completely.

First you need to determine what the problem is, namely, in the vestibule or in the locking mechanism itself.

This is done as follows:

• Open the door;
• We press the trunnion with our hand and hold it in the state in which it is located in the “closed” position;
• We are trying to turn the handle.

If the handle rotates properly, then the problem is in the clamps secured around the perimeter of the frame. If the handle still does not reach the end, then the locking mechanism has become unusable and will need to be repaired or replaced.

Elimination of pins jamming on clamps on the frame

We determine which clamp the trunnion rests on. To do this, remove one clamp at a time and check whether the handle is stuck or is already scrolling.

If, after removing the next clamp, the handle began to turn without jamming, then that was the problem. There are two ways to fix the problem:

• If the clamp was initially installed poorly on the profile, screw it lower or higher than the original position;

• If the reason is not installation, but sagging of the sash (90% of cases), we adjust the position of the sash in the desired plane.

By the way, in some cases you can do without rearranging the clamps on the profile or without adjusting the position of the sash. To do this, just adjust the clamping eccentric on the trunnion.

We look at the eccentric located near the problematic clamp. If it is turned in a horizontal direction, then we try to set it in a vertical position, in the so-called “ summer mode" After this we try to close the sash.

Eliminating jamming in the handle

If the plastic window does not close, the handle does not turn, and a characteristic crunching sound is felt, do the following:

• Using a syringe (enema), we blow off dust from the area of ​​the fittings in the immediate vicinity of the trunnion or clean it from dirt with a clean paint brush;
• We dig the moving parts with mineral oil or spray VD-40 into the gaps of the moving parts;
• We close the sash and lower and raise the handle several times.

If the creaking and jamming have disappeared along with the dirt, the surface of the fittings can be wiped free of grease and normal operation of the window can begin. If the creaking and jamming have not disappeared, everything is a little more complicated, which means you will have to look for the problematic part of the fittings and eliminate the defect.

To do this we do the following:

• With the sash open, lower the handle to the bottom position until it stops, which is caused by jamming;
• We inspect the position of the trunnions along the perimeter of the sash;

• We will see that all the pressing eccentrics are located in the same position, while one trunnion will necessarily be located at the end of the slot, just as if the handle were in a completely closed state;
• In this case, move the handle to the 90° position, as if the sash were completely open;
• We unscrew the screw securing the fittings at the nearest connection and bend the metal strip, freeing the movement of the trunnion;
• Manually move the eccentric from the extreme position to the position in the middle of the slot;

• Reassemble the disassembled plank in reverse order;
• We check the functionality of the locking mechanism.

If the jamming stops and does not resume after several turns of the handle, the repair can be considered complete.

Before assembling the fittings, do not forget to spray silicone grease or other lubricants that are resistant to humidity and low temperatures into the gaps of the moving parts in the problem area.

Let’s say you took all of the above tips into account and set about repairing the window, but not a single instruction helps. If the sash does not close and the handle does not work, do not rush to call professionals, just carefully inspect the perimeter of the narthex, maybe there are foreign objects there.

A curious incident from life

The owner of the apartment, after washing the outside windows, noticed that one of the sashes did not close. The owner of the apartment did not understand the reason for the breakdown, so she called a professional repairman.

The question was the following: the plastic window does not close well, what should I do?

Upon closer examination, it turned out that the impossibility of closing the window was caused by the displacement of the external visor fixed to the profile. The visor was offset by 10 mm and this was just enough for it to rest against the frame.

During the repair, the visor was moved to the correct position, and the sash began to close again.

Conclusion

What conclusions can be drawn from this article? If the window does not close completely, this is not yet a reason to contact professional craftsmen. After all, you can do everything yourself, spending a little free time on it and using simple accessible tools.
