The appearance of condensation on the inner walls of the chamber or noticeable freezing of products often indicates that the seal is broken. In most cases, the culprit is a worn-out one, which no longer fits tightly to the metal body. Timely replacement of this element will not only return the unit to operability, but will also significantly reduce energy consumption. sealing profile, which no longer fits tightly to the metal body. Timely replacement of this element will not only restore the unit’s functionality, but will also significantly reduce energy consumption.
Many owners of household appliances Indesit or Atlant erroneously believe that to eliminate the gap it is enough to simply wash the part or warm it with a hairdryer. However, if the rubber has lost its elasticity, is covered with microcracks or is deformed, these measures will only give a temporary effect. A complete replacement is the only correct solution for restoring thermal insulation.
The process of restoring tightness can be done independently, without calling a specialist. To do this, you will need a minimum set of tools and a new spare part, selected strictly for your model. In this article we will analyze all stages of the work, from diagnostics to the final inspection, so that you can do everything efficiently and safely.
Diagnostics of the condition of the seal
Before going to the store for a new part, you need to make sure that the problem lies in the rubber. Sometimes a loose fit is caused by a skewed door or faulty hinges, but the seal itself is still working properly. Carefully inspect sealing collar around the entire perimeter.
Pay attention to the presence of visible defects: cracks, tears, abrasions or areas where the rubber has become hard and brittle. If there is no obvious damage upon visual inspection, perform a simple test with a sheet of paper. This method allows you to identify even small gaps through which cold air escapes.
⚠️ Attention: If the seal is covered in sticky residue or mold, try first washing it thoroughly with warm water and a mild detergent. Sometimes contamination prevents a tight fit, and replacement is not required.
To carry out the test, take a regular A4 sheet and clamp it with the refrigerator door around the perimeter. If the paper falls out or is removed without the slightest resistance, it means that the seal in this place is broken. Walk along the entire frame in this way, noting problem areas.
Selection and selection of a new seal
Purchasing the wrong spare part is the most common mistake that negates all repair efforts. Seals come in different profiles, sizes and mounting methods. There are no universal solutions, so you need to look for a part designed specifically for your model.
Find the technical data sheet of the refrigerator or a sticker with the serial number, which is usually located inside the chamber on the side wall or on the back panel of the case. This data is necessary for searching in spare parts catalogues. You can also measure the old seal, although this method is less accurate due to its deformation.
- 🔍 Type of fastening: may be in a groove (inserted into the door groove) or with screws (screwed through a metal strip).
- 📏 Dimensions: the length and width of the profile must match the original to within millimeter.
- 🏭 Material: choose high quality magnetic rubber that does not harden in the cold.
When ordering through online stores, be sure to check your profile photo with your sample. Pay special attention to the corners: for different manufacturers (for example, Bosch and LG) the shape of the corner joints may differ radically. If you are in doubt about the choice, it is better to consult with a specialist before paying.
Necessary tools and preparation
For a successful replacement, you do not need a complex professional tool. Most of the work is done using items that can be found in every home. The main thing is to prepare the work area and provide good lighting, since some fastening elements may be hidden.
Free up the space in front of the refrigerator in advance to have access to the door from all sides. It is recommended to remove shelves and products to reduce the weight of the door and make it easier to handle. Also prepare a container for folding small parts so as not to lose anything.
☑️ Tools for replacement
During the process, you may need a hairdryer to soften the new rubber before installation, especially if it has been lying in the warehouse for a long time in a rolled-up state. Do not use open fire or too high temperatures to avoid damaging the structure of the material.
Removing the old seal
The process of removing the old rubber band depends on the type of fastener installed on your refrigerator. If the seal is attached with screws around the perimeter, first carefully unscrew them, holding the door so that it does not move. After this, remove the metal clamping strip.
If the profile is inserted into the groove, act carefully so as not to damage the plastic of the door. Start from one of the top corners, pulling the rubber slightly and using a flat-head screwdriver wrapped in a cloth to help you. Move gradually around the perimeter, releasing fastening from the groove.
⚠️ Attention: Do not use excessive force when dismantling. The plastic doors of modern refrigerators can be fragile, and a sharp jerk can lead to cracks in the body.
After removing the part, thoroughly clean the surface of the door and the groove from residual glue, dirt and grease. Use warm water with a mild detergent added. A clean surface will ensure better adhesion and a tight fit of the new seal.
What to do if the old seal is glued?
In rare cases, seals can be glued. In such a situation, carefully heat the joint with a hairdryer to soften the adhesive layer, and slowly remove the rubber, helping with a spatula. Remains of glue are removed with a special solvent or alcohol.
Installation and installation of a new rubber band
Before installation, it is recommended to straighten the new rubber band and let it lie in a straightened state at room temperature for several hours. If the profile has creases, they can be carefully heated with a hairdryer, but do not overheat the material so that it does not lose elasticity.
Start installation from the top corner. If the fastening is screw, insert the edge of the profile into the corner, line up the holes and tighten the first screw, but do not tighten it all the way right away. Then move to the opposite corner, fixing the middle.
When installing in a groove, first tuck the corners, and then, pressing with your thumb, push the side of the profile into the groove along the entire perimeter. Movements should be confident, but smooth. Make sure that the rubber is not turned out anywhere and lies flat.
| Mounting type | Installation features | Tool |
|---|---|---|
| Into the groove (latch) | Pressed with your finger perimeter | Hands, hair dryer |
| On screws | Requires hole alignment | Screwdriver |
| On glue | Applying glue, pressing for a while | Glue, clamps |
After the entire circuit is installed, check the tightness of the fit. The door should close with a characteristic clap, and the rubber should evenly fit the body around the entire perimeter without gaps or bulges.
Adjustment and checking the result
The final stage is checking the quality of the work performed. Do the test again with a piece of paper around the entire perimeter. Now the sheet should be removed with noticeable effort or not at all, which indicates that the tightness has been restored.
Pay attention to the operation of the magnets. They should ensure a tight fit of the door to the body without external forces. If the door does not close completely or comes off in places, it may be necessary to adjust the hinges or additional heating of the seal.
⚠️ Attention: Immediately after installation, the door may be difficult to close. This is normal for new tires. Give it 2-3 days to “grind in”, after which the closing force will decrease.
During the first week after replacement, periodically check the condition of the seal. Make sure that it does not move away from the door and that condensation does not form on the inner walls. A correctly installed part will last for many years, ensuring the efficient operation of your refrigerator.
How often do you need to change the seal?
The average service life of a high-quality seal is 5-7 years. However, with active use, frequent opening of the door or exposure to aggressive detergents, replacement may be required sooner. Monitor the condition of the rubber and change it at the first signs of loss of elasticity.
Is it possible to use a universal seal?
There are so-called universal profiles that can be cut to size. However, they are often inferior to OE parts in terms of fit and durability. For reliable operation, it is better to look for the original part number or a high-quality analogue created specifically for your model.
What to do if the door is warped after replacement?
If after installing a new rubber band the door is warped, the problem may not be in the seal, but in the fact that you did not align the door correctly during installation. Try loosening the hinges, aligning the door and tightening them again. Also check if there is anything in the way inside the chamber.
Does the new seal need to be lubricated?
It is not recommended to lubricate the rubber with oil or Vaseline, as this can lead to its swelling and damage. If the rubber is too dry and squeaks, you can wipe it with a special silicone lubricant for rubber products, but usually this is not necessary.
