Brand refrigerators Don are deservedly popular due to their reliability, But over time, even the best quality equipment requires maintenance. One of the most common problems faced by owners of these units is the wear of the rubber seal on the door. If you notice that the door has become less adherent to the body, frost has appeared in the corners of the chamber, and it has become noticeably warmer inside, it means that the seal is broken. This is not just a minor malfunction, but a signal that compressor is forced to work in increased mode to compensate for the loss of cold.
Many owners mistakenly believe that replacing a seal is a complex process that requires calling a technician and significant financial costs. In fact, in most refrigerator models Don the door design allows you to perform this procedure yourself at home. The main thing is to choose the right consumables and strictly follow the algorithm of actions so as not to damage plastic elements the housing. Ignoring the problem can lead to failure of expensive components of the cooling system.
In this article we will analyze in detail all the stages of replacing the sealing tape, from diagnostics to checking the quality of the work performed. You will learn how to distinguish an original profile from a universal analogue, what tools you will need and how to avoid common mistakes. Restoring the seal of the chamber will extend the life of your refrigerator and reduce electricity consumption.
Diagnostics of the condition of the seal and the need for replacement
Before you start looking for a new rubber band, you need to make sure that the problem lies there, and not in skewed loops or breakage latches An initial visual inspection allows you to identify obvious mechanical damage: cracks, abrasions, tears or deformation of the profile. If mold is visible on the surface of the seal, which is not removed by cleaning agents, this is also an indication for replacement, since fungal spores can penetrate the rubber structure.
There is a simple and effective way to check the tightness, known as the paper test. You will need a regular A4 sheet or even a banknote. Open the refrigerator door, insert a sheet between the body and the seal, and close the door. Now try to pull out the paper. If it comes out easily, without noticeable resistance, it means that it is insufficient in this place. Carry out a test along the entire perimeter of the door, moving the sheet every 10-15 centimeters. pressure force in this place is insufficient. Carry out the test along the entire perimeter of the door, moving the sheet every 10-15 centimeters.
⚠️ Attention: If the paper is pressed tightly only in some places, but slides freely in others, this indicates uneven wear of the seal or deformation of the door itself. In this case, simply replacing the rubber band may not solve the problem completely.
Another sign of a malfunction is the formation ice crust in the corners of the freezer or refrigerator compartment. Warm air entering through leaks contains moisture, which instantly freezes on the cold walls. Also pay attention to the operation of the compressor: if it turns on more often than usual or works almost non-stop, this is a sure sign that the system is losing coolness. In modern models with electronic control, the emergency temperature indicator may light up.
Selecting a suitable seal for the Don refrigerator
The key stage of repair is the correct selection of components. Seals for refrigerators Don may differ in cross-sectional profile, method of fastening and geometric dimensions. The most reliable option is to purchase an original spare part, the number of which is indicated in the technical documentation or on the device nameplate. However, it is not always possible to find the original, especially if the refrigerator model was released several years ago.
In this case, universal or specialized analogues come to the rescue. When choosing, pay attention to the type of fastening: in most old and medium-sized models Don is used magnetic tapeinserted into the groove of the profile, and the profile itself can be attached to the door with screws or using the dovetail method (snapping into the groove). It is important for beginners not to confuse the profile for single-chamber and double-chamber refrigerators, since they can have different widths and bend shapes.
The material used also matters. A high-quality seal is made of special frost-resistant rubber or thermoplastic elastomer, which retains elasticity at low temperatures. Cheap analogues made of hard rubber can “stiffen” in winter, and the seal will be broken again. It is recommended to choose profiles with antibacterial impregnation, which is especially important for kitchen appliances.
Necessary tools and workplace preparation
Successful work does not require complex professional equipment. All the necessary tools can usually be found in the drawer of any home craftsman. However, preparation must be thorough, since working with plastic parts requires care. Any careless movement can lead to scratches on the body or chips on decorative elements.
Here is the basic list of tools you will need:
- 🔧 Screwdrivers: cross and flat (2-4 mm in size) for unscrewing screws and prying up the edges of the profile.
- ✂️ Scissors: sharp, with thin tips, for trimming excess material or trimming corners.
- 🌡️ Hair dryer: construction or ordinary household for heating the rubber so that it becomes more elastic and straightens.
- 🧽 Rags and degreaser: alcohol or a special product for cleaning the surface before installation.
Before starting work, the refrigerator must be defrosted and disconnected from the power supply. This will not only protect you from electric shock, but will also make the hoses and seals softer if there is still cold in the chamber. It is better to remove the door and place it horizontally on a soft surface (for example, on a blanket or thick cardboard) to provide easy access to the ends on all sides.
☑️ Preparation for replacement
Technology for removing the old seal
The dismantling process depends on how exactly the rubber band is secured in your models Don. If the profile is fastened with screws, the task is simplified: you just need to find the fastening points (usually they are hidden under the elastic flap or located in the corners) and unscrew them. After this, the old seal can be easily removed from the body.
If the rubber is inserted into a special groove (groove) around the perimeter of the door, you need to act carefully. Start from one of the top corners. Carefully bend the edge of the seal and, prying it with a flat-head screwdriver (wrapped in cloth so as not to scratch the plastic), pull it out of the groove. Move gradually, freeing 10-15 centimeters of the contour. Do not pull the rubber sharply, as it may tear, and parts of it will remain inside the groove, which will complicate the installation of the new tape.
⚠️ Attention: When removing the old rubber, carefully inspect the groove itself on the door. Dirt, glue residues or oxides often accumulate in it, which must be carefully removed before installing a new profile.
If the seal is glued, it is heated with a hairdryer to soften the adhesive layer, and then slowly scraped off with a spatula. Remaining adhesive is removed with a solvent suitable for plastic. It is important not to use aggressive chemicals that can damage the painted surface of the door.
Step-by-step instructions for installing a new rubber band
Installing a new seal is the most critical step. Before installation, it is recommended to warm up the new elastic band with a hairdryer or keep it in a warm room (at least 24 hours) so that it straightens and becomes elastic. Cold rubber is brittle and does not take the desired shape well, which can lead to the formation of creases.
If you are working with a profile that is inserted into a groove, start installation from the top corner. Insert the corner of the seal into the groove, making sure that the magnetic tape is in the correct position. Then, using pressure with your thumb or using a blunt spatula, tuck the profile into the groove around the perimeter. Movements should be confident, but smooth. Pay special attention corner joints: in these places the rubber often gathers in folds that need to be carefully straightened.
The secret of ideal corners
To make the corner fit perfectly, slightly pull the elastic to the sides of the corner, tuck in the middle, and then spread excess material evenly on the sides, forming a neat fold.
For models with screw fastening, the process is even simpler: align the holes on the profile with the holes on the door and tighten the screws. Do not pinch them too hard to avoid pushing through the plastic. After installation around the entire perimeter, check that the rubber has not turned out anywhere and whether it fits tightly to the body.
Comparison of types of fastenings for different modifications:
| Type of fastening | Installation complexity | Required tools | Frequency in Don models |
|---|---|---|---|
| Insertion in the groove (groove) | Medium | Hair dryer, spatula | High (most models) |
| Screw fastening | Low | Screwdriver | Medium (old and some new models) |
| Adhesive connection | High | Hair dryer, solvent, spatula | Low (rarely) |
Finishing and checking the quality of work
After the new elastic is installed, do not rush to plug in the refrigerator. Give the material time to “sit down” and take its final shape - usually 2-3 hours is enough. If you used a hair dryer to heat it up, make sure the rubber is completely cool. Visually inspect the perimeter: the gap between the seal and the body should be minimal and uniform along the entire length.
Repeat the test with a sheet of paper, which was mentioned at the beginning of the article. Now the sheet should be removed with noticeable force along the entire perimeter of the door. If the pressure remains weak in some places, try heating this area again with a hairdryer and pressing the door with your hand until it cools down. Sometimes it takes several heating and cooling cycles for the profile to fully straighten.
⚠️ Attention: On the first day after replacing the seal, try not to slam the door or overload the shelves. The rubber needs time to adapt to the temperature and humidity inside the chamber.
Turn on the refrigerator and leave it to work without loading food for 4-6 hours. During this time, the unit should reach operating temperature and turn off. If the compressor operates normally and no excess frost appears on the walls, it means the replacement was successful. You will immediately notice that the equipment has become quieter.
How often do you need to change the rubber seal?
The average service life of a high-quality seal is 5-7 years However, with active use, frequent opening of the door or use of aggressive chemicals during cleaning, replacement may be required earlier - after 3-4 years. Check the condition of the rubber regularly.
Is it possible to restore an old rubber band without replacing it?
Temporary restoration is possible if the rubber is intact, but has lost its elasticity. It can be heated with a hairdryer or soaked in hot water (about 70-80 degrees) for several minutes. This will straighten out the deformations, but the effect will be short-lived if the material is already worn out.
Why did the door begin to close tighter after replacement?
A new rubber band always has greater thickness and elasticity than a worn one. This is fine. After 1-2 weeks of active use, the material will shrink a little and the closing force will become comfortable. It is not recommended to lubricate the rubber band with oil, as it destroys the rubber structure.
