Reduction cooling efficiency, the appearance of ice on the rear wall or the constant hum of the compressor often indicate a violation of the chamber seal. Equipment owners Atlant often face a problem when the door no longer fits tightly to the body due to wear of the magnetic tape. Seal (cuff) is an elastic rubber that over time loses its properties, cracks or deforms, ceasing to perform a barrier function.
Ignoring this defect results in warm, moist air constantly entering the chamber. The compressor is forced to work without interruption, trying to compensate for heat loss, which leads to overload of the motor and a sharp increase in electricity bills. Timely replacing the seal allows you to extend the service life of the unit and restore its standard characteristics.
You can perform this procedure yourself at home, without resorting to the services of service centers. The process does not require complex specialized tools, but does require precision and attention to detail in the design of your model. In this guide, we will analyze all stages of the work, from choosing the right spare part to the final adjustment of the door.
Diagnostics of the condition of the sealing rubber
Before going to the store for a new part, it is necessary to conduct a thorough visual and tactile inspection of the current condition of the cuff. Often, owners only notice a problem when it becomes obvious, but early signs of wear and tear can be identified early. Inspect seal along the entire perimeter, paying attention to the presence of microcracks, especially in the corners and bends.
If the rubber looks intact, but the cold still goes away, do a simple test with a sheet of paper. Open the door, place the sheet of paper against the body and slam it shut so that the paper is sandwiched between the rubber and the metal. Try to pull out the sheet: if it comes out freely or with minimal effort, it means that tightness the seal is broken and there is no seal.
Another sign of a malfunction is the formation of condensation or a “fur coat” in the lower part of the freezer or at the junction of the doors. This indicates that warm air penetrates into the cracks, which instantly condenses and freezes. It is also worth checking magnetic tapebuilt into the rubber: if it has weakened in places or fallen out, a full fit cannot be achieved even with the ideal appearance of the cuff.
⚠️ Attention: If you find mold or black deposits on the inside of the seal, just washing it may not be enough. The fungus often penetrates the structure of the porous rubber, and after a while the problem returns. In such cases, a complete replacement is the only hygienic solution.
Choosing the appropriate seal model
Refrigerators Atlant are produced in a huge number of modifications, and there are no universal seals for them. Each series, be it classic two-chamber models or modern units with the No Frostsystem, has its own geometric profile features. Buying the wrong rubber will result in the door not closing or closing with enormous force, damaging the hinges.
For an accurate selection, you need to know the model of your refrigerator. This parameter is indicated on a technical sticker, which is usually located inside the camera (on the side wall or ceiling) or on the rear panel of the case. Look for a code starting with letters, for example MHM, KShD or ATL, followed by numbers. It is this code that needs to be reported to the seller or entered into the search.
Where can I find the model code if the sticker has been erased?
If the technical sticker is unreadable, The model code is often duplicated in the warranty card or operating instructions. You can also try to find the nameplate on the back wall, although getting there is more difficult. In extreme cases, experts can determine the model by the internal volume of the chambers and the location of the compressor.
Original seals Atlant are made of special frost-resistant rubber, which retains elasticity at low temperatures. Cheap analogues may become stale after a couple of months, and the procedure will have to be repeated. When ordering, pay attention to the cross-section profile: it can be single, double, or have a complex petal structure.
Necessary tools and preparation
Replacing a cuff is a clean operation, but requires certain preparation of the workplace. You will not need heavy professional tools, but you should have a minimum set on hand so that the process goes smoothly and without damaging the plastic of the door.
- 🔧 Screwdriver (Phillips or flat-head) - may be needed to remove decorative panels or loosen fasteners.
- 🧣 Hair dryer (construction or household) - necessary to heat up the new rubber so that it straightens and sat down in shape.
- 🧼 Soap solution and soft rags - for degreasing the surface before installation.
- 🔨 A small rubber hammer (optional) - for carefully tapping the profile in difficult places.
Before starting work, a refrigerator is necessary de-energize. Unplug the power cord to reduce the risk of electric shock, especially if you work near electrical components or door wiring (such as lights). It is also recommended to release the door shelves to reduce the load on the hinges during manipulation.
☑️ Preparation for replacing the seal
Removing the old seal
The method of removing the old seal directly depends depending on the type of attachment to the door. In refrigerators Atlant there are two main options: insertion into a special groove (profile) or fastening with self-tapping screws around the perimeter. You can determine the type by carefully examining the inner edge of the rubber.
If the seal is inserted into the groove, it must be carefully pryed with a blunt object (for example, a plastic card or a screwdriver with a wide tip, wrapped in fabric) in one of the corners. Pull the rubber towards you, being careful not to damage the plastic door body. Move gradually around the perimeter, releasing the cuff from the channel. Be careful not to break the plastic protrusions of the groove.
In the case of fastening with screws, the situation is more complicated. You will need to find the heads of the screws, which are usually hidden under the rubber flap or in the corners. Unscrew them, holding the seal with your other hand so that it does not fall suddenly. After removing all the fasteners, the old rubber will easily separate from the door.
⚠️ Attention: When dismantling the old seal, especially if it has served for many years, proceed with extreme caution. Rubber can crumble and leave a sticky residue that is difficult to remove. Do not use sharp metal objects (knives, blades) for cutting, as there is a high risk of damaging the plastic of the door or getting injured.
Installing a new seal: step-by-step instructions
A new seal is often supplied folded or twisted, so it will not be able to “go into place” right away. Before installation, it is recommended to straighten it and warm it up a little. This will make the material more elastic and pliable. If you try to tighten cold, hard rubber, it may tear or become deformed.
The installation process depends on the type of fastening determined earlier. If your Atlant involves insertion into a groove; start installation from the top corner of the door. Insert the edge of the seal into the channel and gradually, in 10-15 cm sections, press it in with your fingers or a blunt instrument. Move around the perimeter, making sure that the profile lies evenly, without twisting.
For models with screw fastening, the process looks different:
- Attach the new seal to the door, aligning the holes for the fasteners.
- Start fixing from the corners, screwing in the screws, but do not tighten yet them all the way.
- Evenly distribute the rubber around the perimeter, eliminating tension.
- Finally tighten all the screws, making sure that the head is recessed and does not interfere with closing.
After installation, be sure to wipe the surface seal with a soap solution to remove dust and factory grease, improving adhesion. Inspect the entire perimeter: there should be no bulges or gaps anywhere. If you see that the rubber is bulging in some places, carefully adjust it with your fingers while it is warm.
Checking tightness and adjustment
After the new seal is installed, you cannot immediately load the refrigerator with food. It is necessary to check the quality of the work performed. Let the equipment stand turned off for about an hour so that the rubber finally “settles” and takes a working shape at room temperature.
Carry out a repeat test with a sheet of paper around the entire perimeter of the door. Now the paper should be removed with noticeable force, and when the door is closed, clear marks of pressure should remain on the sheet. If in some place the paper slides freely, it means that a gap has formed there.
Often, after replacing the rubber, door adjustmentis required. The new cuff may be thicker than the old one, causing the door to not close completely or, conversely, too tightly. In this case, it is necessary to loosen the hinge mounting bolts and move the door slightly up, down or to the side, achieving the ideal gap.
| Symptom | Possible cause | Elimination method |
|---|---|---|
| The door does not close until it clicks | The seal is too thick or wrapped | Straighten the rubber, heat it with a hairdryer, check the hinges |
| Gap in the bottom corner | The door is skewed or loose hinges | Adjusting the height of the refrigerator leg or tightening the hinges |
| Whistling when closing | Vacuum seal is too strong | Lubricate the seal with silicone grease, check the ventilation |
| Waves on the rubber | Incorrect installation (stretching) | Remove the area, warm it up and lay it again without tension |
What to do if the door is skewed after replacement?
Sometimes new rubber creates additional resistance, and old, worn-out hinges cannot withstand the load, warping. In this case, it is necessary to remove the door completely, check the condition of the hinge bushings and, if necessary, replace them or use washers for alignment.
⚠️ Attention: If, after replacing the seal and adjusting the hinges, the problem with tightness persists, it may not be the rubber. Check the evenness of the refrigerator body itself and the condition of the inner box. In rare cases, deformation may be caused by violation of transportation rules or manufacturing defects.
Care and prevention of the new seal
In order for the new seal to serve for a long time and not lose its properties, it must be properly cared for. Rubber does not like aggressive chemicals, so when cleaning the refrigerator, use only mild detergents or special sprays for household appliances. Avoid using solvents, bleach, or abrasive powders. served for a long time and did not lose its properties, it needs to be properly looked after. Rubber does not like aggressive chemicals, so when cleaning the refrigerator, use only mild detergents or special sprays for household appliances. Avoid using solvents, bleach, or abrasive powders.
Once every 3-4 months it is recommended to lubricate the rubber surface with a special silicone grease. This prevents drying out, cracking and maintains the elasticity of the material even at low temperatures. This simple procedure can extend the life of the cuff by several years.
It is also important to ensure that no food, crumbs or packaging gets stuck between the seal and the body. Even a small foreign object can create a micro gap through which the cold will escape. Regularly wipe the folds of the seal with a damp cloth.
Following these simple operating rules will allow your refrigerator Atlant to work efficiently for many years. Replacing the seal is a skill that pays off from the very first week, when you notice a decrease in compressor noise and the absence of excess ice in the chamber.
How often do you need to change the seal on a refrigerator?
The average service life of a high-quality seal is 5-7 years. However, with active use, frequent opening of doors or use of aggressive detergents, replacement may be required earlier - after 3-4 years. Monitor the condition of the rubber and change it at the first signs of loss of tightness.
Is it possible to restore the old seal if it has simply come off?
If the rubber is intact, has no cracks and has simply moved away from the body, you can try gluing it. To do this, use special glue for rubber or hot glue. However, this is a temporary measure: over time, the glue will lose elasticity and the seal will come off again. A complete replacement is more reliable.
Why does the new seal smell like rubber and when will the smell disappear?
The smell of new rubber is normal. It is determined by production and storage technology. Usually the smell disappears on its own within 1-2 weeks of use. To speed up the process, you can wipe the seal with a weak solution of vinegar or citric acid, but do not use strong flavors so as not to cover the smell of the food.
Does replacing the seal affect the refrigerator warranty?
If the warranty period is still valid, replacing the seal yourself may be grounds for denial of warranty service if the technician finds fault with your actions the cause of the breakdown. During the warranty period, it is better to contact an authorized service center.
