Even the most reliable structures and mechanisms are not immune from breakdowns. The popular plastic windows are no exception. The elements that are used most frequently are always the first to fail. One of the common problems with plastic windows is broken or jammed handles. After all, it is the window handle that bears all the loads associated with opening and closing the window.

In fact, the handle of a plastic window is part of a complex mechanism, because it serves not only to pull the sash when opening or closing, but also to control the pressing mechanism, which is also the sash lock. If the handle becomes faulty, the sash will remain in one of the positions - either closed or open.

The most common problems:

• the handle is jammed in the “closed” position even though the sash is open;
• the handle does not turn at all or turns, but not completely;
• The window handle has become loose.

Despite its apparent simplicity, a plastic window and all its elements are complex mechanisms that are very easy to damage during production repair work without proper experience and knowledge. In order not to aggravate the breakdown, it is better to overpay the technician for the call, but keep all the fittings that need to be repaired.

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 to troubleshoot problems, but the price of professional services is 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 the vertical plane relative to each other and the window does not close tightly.

A less common cause is the journals sticking inside locking system. This problem occurs in those double-glazed windows where manual control and automatic closing. 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 the gaps of the moving parts on problem area silicone grease or other lubricants, resistant to humidity and low temperatures.

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.

There were problems with the window operation and were not found the right advice? Ask a question in the comments to the text, and I will definitely answer it. In addition, watch the video in this article, maybe you will find the necessary explanations in it.

Plastic windows are in demand, practical and durable. But often, failure to comply with the operating rules of the window structure can lead to a serious problem - the plastic window does not close. Some types of damage can be dealt with on our own without involving expensive specialists. To do this, it is enough to understand the main causes of malfunctions and how to eliminate them.

Causes of malfunctions of plastic windows

Often, PVC window malfunctions arise as a result of improper operation or maintenance. In some cases, problems may be associated with a manufacturing defect, a violation of installation technology, poor quality or wear and tear of the window structure.

The main reasons for the breakdown of a plastic window include the following:

• errors in the installation of window fittings and working mechanisms that are responsible for opening and closing;
• errors in window installation and violation of the overall geometry of the structure;
• distortion, subsidence and loss of sashes;
• wear or mechanical damage to sealing elements;
• entry of small debris, dust, dirt and foreign objects into the operating mechanism of the window;
• scissors falling out of the grooves;
• low quality window construction;
• mechanical damage to double-glazed windows.

Timely Maintenance, maintenance good condition working mechanism and all structural elements guarantee the quality and durability of the plastic window.

Each type of breakdown is individual and requires a competent choice of methods for eliminating it.

Warping or sagging of the window sash

Over time it's even correct installed window loses its thermal insulation characteristics. This is often due to misalignment or sagging of the sash, which leads to the formation of cracks along the entire perimeter of the frame. And in case top corner moved away, this will also not allow you to set the sash in the correct position.

To eliminate this problem, adjust the angle of the sash and correct position loops You can repair a window as follows:

1. Decorative trims are dismantled to gain access to the adjusting screws in the window hinges. The holes are made for a hex screwdriver or a star key.
2. Using the selected tool, the screws are adjusted clockwise by 1-3 mm in order to correctly adjust the window sash.
3. Next, the window is checked for opening and closing to ensure that the sash is not skewing or sagging. Decorative overlays are installed in their place.

The window does not fit tightly to the frame

Plastic window does not close completely, which violates the tightness of the structure. This occurs as a result of wear of the sealing strips or incorrect adjustment eccentrics.

The problem is solved as follows:

1. The blocking element on the end of the frame is aligned in the desired direction.
2. The upper corner of the sash is carefully pressed with your hand.
3. The handle turns smoothly to the side until a characteristic click appears. This indicates that both grooves are in the desired position.
4. Next, the sash closes tightly and the handle goes down.

To prevent a similar malfunction in the future, it is recommended to follow simple rules:

• sealing tapes require periodic lubrication once a year and complete replacement every 6 years;
• There are two positions for adjusting the eccentrics: winter and summer. The summer position ensures a loose fit of the window sashes to the frame for micro-ventilation. To set the winter mode, the eccentrics are rotated 90 degrees. Similar elements are found on end side valves

The window handle is jammed in the “closing” mode

If you cannot close a plastic window - the handle does not turn all the way or it is jammed in the “closed” mode, this may indicate that the lock is not working properly. To correct the problem, the locking device is pressed against the sealing tape and the handle is moved to the correct position.

Often, as a result of thermal expansion of materials, the blocker can fall out or move away from the groove in which it is supposed to fit. To eliminate the malfunction, you should place any seal under the groove, having first removed it from the frame.

If the lock does not work as a result of the sash sagging or skewing, so the handle does not close all the way down, then it is necessary to vertically shift the groove and.

The handle is stuck in the upper “ventilation” mode

Why doesn't the plastic window close from ventilation mode? The main reason is the displacement of the “scissor” fitting element, which allows the window sash to be opened slightly for ventilation.

If the tilt mechanism is used simultaneously to open and tilt the sash, this will damage the bottom hinge.

If the scissors element is stuck, you can fix it as follows:

1. The sash is removed from the frame. First, the decorative trim is removed from the top hinge, the pin is turned with the tip of a knife, and then pulled out manually or using pliers.
2. Next, the sash is slightly lifted up and removed from the hinge located at the bottom of the structure.
3. The dismantled sash is placed on a flat surface.
4. The scissors are returned to their place in the grooves specially designed for them. Sometimes it is necessary to press the lock on the sash and turn the handle.
5. The functionality of the handle is checked - turns in different sides when the locking device is pressed.
6. The sash is hung on the hinges, the pin is driven in with a hammer.
7. Checking window fittings - turn the handle and tilt the sash for micro-ventilation.

Loose or broken window handle

Often, loosening or breaking the handle leads to the fact that the Euro-window in the house is difficult or almost impossible to close. As a result, the window fittings are poorly connected to the handle rod, which makes it practically uncontrollable.

The problem can be solved by tightening the handle fasteners. The decorative strip is lowered 90 degrees to provide access to the adjustment screws. Using a Phillips screwdriver, tighten the screws by 2-3 mm, after which the bar returns to its place.

In some cases, the operating mechanism of the rotary knob may break, which entails complete replacement. Installing a new part is quite simple. The decorative strip on the handle is rotated 90 degrees, the bolts are unscrewed with a screwdriver or screwdriver, and the handle is dismantled. Installed new mechanism bolts are tightened onto the fixing elements.

Additionally, you can install a limiter on the opening of the handle. A comb is mounted at the base of the handle, which allows you to set modes for macro- and microventilation. Next is executed standard installation pens. Sometimes fittings are replaced when installing a handle with a lock.

The handle makes a full 360 degree turn and the window sash does not open. The problem lies in the breakdown important detail internal lock - a gear that is designed to control the swing-out plates and bushing. It is quite difficult to repair a part on your own; in this case, you should contact a specialist or replace it. internal lock.

The main types of damage to plastic windows can be corrected with your own hands, having the appropriate skills, knowledge and working tools. To save yourself from problems with window structures and to maximize their service life, it is recommended to carry out timely cleaning, lubrication and adjustment of working mechanisms.

Unfortunately, nothing is eternal in the world. Product materials age and wear out, are subject to contamination, corrosion and deformation. This fully applies to plastic windows. One day you will have to face the fact that your window has stopped closing. Neither the manufacturer's brand nor very careful operation will insure you against this.

What to do in this situation? First of all, don’t panic and rush to change the window. In most cases, the breakdown can be fixed by calling a specialist, in many cases you can fix it yourself. Let's consider the most common reasons malfunction and the sequence of actions to eliminate it.

First of all, you need to carefully inspect the window and clarify what type of breakdown you are encountering.

Summary table of types of plastic window faults and their causes

Plastic windows have gradually become the norm for most families. If a few decades ago this was a sign of luxury and wealth, now it is rather a necessity. However, more and more often you can hear complaints from users of new types of double-glazed windows that the window opened in two positions at once. What to do in such a situation? Why does this happen and how can I put everything back in place correctly?

Causes of the problem

As a rule, this situation is not a sign of a faulty glass unit. Users often make certain mistakes, which lead to such inconveniences. You should consider the main factors that lead to the window opening incorrectly. Knowing them, you will be able to use the windows correctly, and you will not have to urgently restore the position of the sash.

To ensure that plastic windows have several opening options, device manufacturers have provided various tilt-and-turn parts. It is thanks to them that our windows can not only be wide open, but also be in ventilation mode. Of course, when the window is equipped with several modes, a device is installed on the sash that blocks opening in two modes simultaneously. However, even despite this, this problem exists in many families.

So, what are the reasons that the sash opens incorrectly and does not close?

1. The sash has sagged.
2. The main fastening of the sash is located on the lower hinge.
3. The opening handle is blocked.
4. A foreign object has entered the system.

A sagging sash is the cause of problematic opening
Often in big houses massive windows are installed. When the area of ​​the glass unit itself is rather large, and it is rarely used, this leads to sagging of the sashes. Under her influence heavy weight The retaining loops begin to deform over time. If they are not adjusted, you may experience opening/closing problems.

Important! Although it is quite possible to solve this problem yourself if the windows were installed quite recently and they are affected by warranty service, we strongly advise you to contact installers. Do-it-yourself repairs may void your warranty.

Unbalanced main mount
A slight awkward movement can lead to the simultaneous opening of the sash in two positions if it was initially secured unprofessionally. In this situation, the spring that regulates the operation of the handle blocks the movement, and returns the sash to original appearance becomes impossible.
In this case, you should act very carefully so as not to damage the mechanism. Do not rush and open the sash before you have fully installed the handle in the correct position.

Locking the handle
Often, emergency opening can occur if the handle is jammed. This happens if a small part, which experts call “scissors,” moves out of place inside the system itself. To solve the problem, you need to carefully disassemble this part of the frame, removing the handle and installing the part in its original place.

Now we should discuss how to adjust a window that, at first glance, is out of order.

Foreign object entry
Before attempting to repair anything, carefully inspect the structure. It is likely that there is some object between the sash and the frame. Sometimes it turns out to be a water drain or something else. By removing the obstacle, you can close the sash without any problems.

How to correct an incorrect sash position

If the cause of emergency opening was subsidence

In this case, you need to try the following steps:

• slightly lift the sash;
• press it tightly to the frame;
• in this position, try to restore the position of the handle.

If the problem is caused by a foreign object

If the window no longer functions normally after the last cleaning, you should carefully inspect the place where the drain plate is installed. Some housewives, for convenience when washing, slip some objects under the sash so that the closing window does not interfere. As a result, the above-mentioned bar often shifts.

This leads to the fact that from the inside it prevents the sash from closing correctly and as a result it may open incorrectly. How to fix this problem?
Inspect the end of the sash. If in your case the root of the problem lies here, perform several blows on this bar, thereby putting it in its original place. The problem should be resolved.

If none of the reasons for the window not closing correctly apply to your case, consider some other methods self-repair designs.

If the window opens incorrectly and the handle does not turn, then the lock is most likely jammed. How to restore full operation of the window system?

1. Find the blocker itself.
   This device is located inside the system and is visible when the window is opened. The main element of this device is always the spring. She is the one who can interfere normal functioning systems.
2. Press down on the element.
3. In this position, press the handle, pointing its position upward.
4. Press the problematic sash itself tightly against the frame as if it were closed.
5. Carefully, gradually move the handle to the lower closed position.

Such manipulations should help ensure that the door closes completely and will continue to be fully functional.

Important! If the handle is locked, most likely you did not detect the lock. If you did everything correctly, try repeating the procedure, only use a stronger pressure on the blocker.

Sometimes incorrect opening of the sashes can be caused by broken fittings or poor quality. If this is the case, then it is not recommended to try to do something yourself, because you can harm the system. In this case, the most correct solution– Call a specialist as soon as possible.

How to avoid opening the sash in two positions at the same time

If you encounter such a problem, you can prevent it in the future. Our simple recommendations on the care and use of windows will help you preserve your double-glazed windows for a long time.

1. To prevent windows from sweating too much (which leads to damage to some parts), it is necessary to ventilate them in a timely manner.
2. Regular (every six months) lubrication of hinges and moving mechanisms will help keep the profile in excellent condition.
3. Use both ventilation modes often, as this will prevent large profiles from sagging and causing difficulties with further use.
4. When opening the sash, move the handle to the end of the position without trying to pull it towards you.
5. There is no need to press hard on the opening handle - this can damage the fragile mechanism.
6. Never use corrosive detergents– simple is perfect liquid soap and special napkins.
7. Always check the work of the installers who install the profile. Most often, many problems begin due to incorrect profile installation.

To the basic rules of small home renovation, first of all, one can attribute accuracy and leisureliness. Compliance with these simple requirements will help you restore the operation of the structure yourself without causing unnecessary harm to it.

The article discusses practical advice how to use windows so that they serve you long time. All this will help you contact the experts as little as possible, solving minor problems on your own and saving your family budget.

Undoubtedly, this situation can lead many to a state of shock. This problem is especially acute in the cold season. The article explains in detail what to do when the sash opens in two positions. The video below will help you see how to put these tips into practice and avoid common mistakes.
