In detail: do-it-yourself repair of door handles for interior doors from a real master for the site my.housecope.com.
During the operation of the door, the handle and the locking mechanism associated with it take the greatest load, so it is not surprising that these elements often break. In most cases, the door handle can be repaired by yourself using a screwdriver and a wrench. Sometimes it is necessary to replace some parts of the mechanism or the entire set as a whole.
Removing the door handle fasteners
There are three main types of door handles:
Round swivel. They are an integral part of a mortise lock, which is activated by turning the handle clockwise or counterclockwise.
Press. The difference from the first point is in the presence of a convenient lever handle, which opens the lock when pressed and closes when returning to its original position. This option is the most convenient for both interior and entrance doors.
Stationary (usually in the form of a ball or staple). These handles are not associated with the lock, they perform a decorative function and serve as a handle when opening the door leaf. Doorknob repair of this type is either tightening loose bolts or replacing it with a new product.
Round rotary handle secured by a lock
When the question arises of how to fix a doorknob, the first step is to familiarize yourself with its device. For those who have come across the installation of a lock on a wooden door, this will not be difficult. Lever and rotary handles consist of the following elements:
Lever.
Locking mechanism with bolt. Its principle of operation is simple - when the handle is turned, the tongue (deadbolt) goes into the mating hole on the door frame and blocks the door.
Square (square pin). Connects the handle and the lock.
A decorative strip that masks the fasteners.
Recoil spring. Responsible for returning the handle to its original position.
Handle travel stop.
Retaining ring.
Plastic ring.

Elements that make up the door handle
If the door handle is found to be broken, you must first determine the cause. The experience of using door handles allows us to distinguish 5 types of breakdowns that are most common:
The handle is sticking, resistance is observed when turning.
The handle falls off, while its fastening remains in place.
The four-sided pin (square) inside the lock breaks.
When the handle is turned, the tongue does not move.
The handle does not return to its original position after turning.
Now let's look at how to repair a doorknob in each of these cases.
Metal parts of the mechanism under constant use are subject to abrasion, especially if dust particles get there. To avoid this, you need to monitor the presence of grease in the lock. Put a little oil on the bolt and twist the handle so that it is evenly distributed over all parts.
Sometimes the reason lies in loose structural elements. It is necessary to correct their position and tighten the fastening bolts.
How to properly lubricate the door mechanism
The culprit of the breakdown in this case is the retaining ring, which is either deformed, or displaced, and may even burst completely. Repair will take time, but it will not be difficult to do it:
Remove the decorative rosette by turning it several times (sometimes it is fastened with a small screw from the bottom, then it must first be unscrewed).
Use a screwdriver to unscrew the screws or bolts to which the mechanism is attached.
Remove the structure and check the condition of the retaining ring. If it is bent or broken (as is the case in most cases), you need to purchase a new part.
Insert the circlip and the entire mechanism into place.
Install the handle and secure it.
Removing the decorative strip and unscrewing the fastening elements of the handle
This is possible only when using cheap low-quality products that are made of a fragile material - silumin. In this situation, you will have to change the mechanism completely. To avoid such breakdowns, it is better to purchase steel structures from trusted manufacturers. Replacing the handle is as follows:
The fasteners at the base of the handle are unscrewed, then it is removed by itself.
Loosening the screw at the base of the handle
If the latch does not work when the door is opened, the cause of the malfunction is a too short square. It gradually moves towards the latch and presses it down. As a result, it cannot function normally. In this case, you need to act like this:
Purchase a longer square on the market. If the length is longer than necessary, you can shorten it with a grinder.
Unscrew one of the handles and take out the structure.
Replace the square and put the handle back in place.
If the handle does not spring back to the horizontal position, this does not mean that it has broken - it may just that the return spring has come off. You can put it in place in the same way as the retaining ring. But sometimes the spring bursts, and this already becomes a problem: it is very difficult to acquire this part on the market. Often in such cases, the entire mechanism is changed.
Spring responsible for returning the door handle to its original position
Sometimes it is required to repair the outer door handle made of metal, or rather replace it, since Chinese silumin fittings often break down. This is easier to do than installing a lock on a metal door. The algorithm of actions is not very different from replacing the handle of an interior door:
The fasteners are removed.
The square is extracted. If it is of a suitable length, you can leave it.
Attach the pads and spacers and place the handle on the square.
They put the bar in place, the deadbolt must snap into place.
In most cases, repairing a doorknob is not difficult, the main thing is to correctly determine the cause. If the structure cannot be repaired, you should think about purchasing high-quality fittings from well-known manufacturers. To get a better idea of how to disassemble a doorknob, watch the following video.
The frequency and intensity of door use in any home is different. However, given the fact that even the highest quality structures and parts are prone to wear and tear, the repair of interior doors is a fairly common occurrence. Therefore, in order to perform it efficiently and ensure a longer service life of the structure, you need to know how to act in case of various types of breakdowns.
Almost any door has a fairly impressive weight and, depending on the frequency of use and the force applied at the same time, the load on the hinges provokes their deformation. At the same time, gaps often appear between the frame and the door leaf. To correct this problem, you can replace the door hinges.
Sometimes the frame itself is deformed. In this case, do-it-yourself repair of interior doors consists in leveling the box. To do this, several holes are made in it deep into the wall and with the help of dowels it is fixed at the required vertical level.
If the blade sags before it gets stuck and the floor covering scratches, proceed as follows:
Check how tight the loops are. In some cases, to solve the problem, it is enough to simply tweak them;
If the hinges are not loosened, you need to fix them deeper.For this, the door is removed and the hinge mechanisms themselves are disconnected;
Deepening can be done with a chisel both in the door leaf and in the frame. After that, the hinges are mounted in their original place.
After this procedure, it is important, initially securing the mechanism with only one screw, to check how the door closes. If the result is unsatisfactory, it is necessary to increase the degree of deepening of the hinge mechanism. Full fixation of the loops is performed only after the desired result has been obtained.
If, in the process of repairing the interior door, significant damage is found in the attachment points of the hinge mechanisms, the correct solution would be to move the hinges above or below the old location.
The most unreliable mechanisms of the entire structure are fittings, and in particular door handles. This is due to the rather heavy loads that fall on them. In order to carry out a high-quality repair of door handles used to open and close interior doors, it is necessary to study the type of the mechanism itself.
So the door handles, based on the principle of operation, are divided into:
Swivel, usually in the form of a ball with a keyhole in the center;
Push-type mechanisms;
Standard, immovable.
The most common cause of jamming malfunctions is insufficient lubrication of product components. To eliminate the malfunction, it is enough to disassemble the handle and treat the parts with lubricant. In some cases, it is permissible to simply apply the oil used for processing sewing machine parts to the transom. Subsequently, it is necessary to turn the mechanism several times.
Such measures are often quite enough to eliminate the squeak that occurs during the use of the handle and jamming of the crossbars. If these manipulations did not solve the problem, it is necessary to completely disassemble the door handle.
In this case, the decorative strip is initially removed and the fasteners located under it are unscrewed. When repairing interior doors with your own hands, you need to carefully consider the washer and the rotary spring. For a detailed inspection of the washer, it is necessary to remove the retaining ring. If these elements are damaged, they must be replaced.
In the event that the reversing spring has been displaced, it is simply enough to reinstall it in its original place. However, in the presence of damage in most cases, a complete replacement of the entire mechanism will be required, since pivot springs for door handles are extremely rare on the market.
If it is impossible to identify the problem, the door handle mechanism is completely removed and disassembled. In this case, any broken part must be replaced. The assembly of the product itself must be carried out in the reverse order of disassembly.
In the event of any problems with the lock, repairing interior doors with your own hands is much easier than if there was a breakdown of the locking mechanism of the front door. In most cases, the causes of problems are:
Foreign objects in the keyhole in the form of litter or a piece of a broken key;
Insufficient lubrication;
Skewed door leaf or deformation of the hinges;
Mismatch of the hole in the frame with the bolt;
Damaged spring or deadbolt mechanism.
If the reason is not in the lock itself, the door leaf should be adjusted. In most cases, it is necessary to tighten or replace the hinge mechanisms. Lubrication of the lock is much more effective when processing the entire interior; for this, the lock must be disassembled. However, even without this, a long-term effect can be achieved. It is enough to apply grease to the bolt using an oiler, syringe or pipette and slowly turn the handle several times.
In the event that the breakdown lies in the mechanism itself, it is necessary to remove and disassemble it. The lock itself consists of a lock and an executive part.For dismantling and disassembly, first of all, the screws located near the core of the product are unscrewed. Next, a key is inserted into the keyhole and the secret is removed by turning it a little. Only then is it permissible to remove the entire lock body.
The case cover itself also has fasteners in the form of small screws. After their removal, the accumulated dust is cleaned and the integrity of all internal components is inspected. If any damage or deformation is found, the part needs to be replaced.
All parts must be lubricated before assembly. If after all the procedures the lock does not work properly, it must be completely replaced.
Many interior doors are made of wood. Since this material is largely exposed to the external environment, it is not uncommon for the web to dry out and crack. The simplest solution in this case is to install metal corners. However, such measures can significantly spoil the appearance of the structure.
In case of dryness, the repair of interior doors can be carried out by processing the canvas with a special adhesive solution. To do this, the door must be removed from the hinges and the entire surface must be treated. Cracks are lubricated more intensively. To achieve the desired effect, the glued door is slightly squeezed with clamps or a press and left in this form until completely dry. After that, the blade can be reinstalled in its original place.
If cracks and chips are found on the glass, it must be replaced. For this, the method of its installation is determined. The glass can be fixed with glazing beads or installed inside the curtain.
To remove glass with glazing beads, you need to lift them with a thin screwdriver or knife near each nail. After that, all the strips and the glass itself are removed. The installation of a new glass is carried out in the reverse order.
