The appearance of a snow coat or ice crust on the back wall of the refrigerator compartment is a signal that cannot be ignored. Owners of equipment Atlant often encounter a situation when moisture begins to accumulate inside the chamber, turning into frost. This not only reduces the usable volume, but also creates a risk of food spoilage.
Modern models, even with the system No Frost, may show signs of freezing under certain conditions. It is important to understand that the physics of the process is simple: moist air condenses on the coldest surface, which is the evaporator or the back panel.
If you notice that the layer of ice is becoming thicker than usual, you need to carry out diagnostics. In most cases, the problem lies in a violation of the tightness or malfunction of the automatic defrosting system. Ignoring the first symptoms can lead to more serious damage to the compressor.
Failure of tightness and deformation of the seal
The most common reason why snow freezes is the ingress of warm, moist air from the room into the chamber. Sealing rubber on the door loses its elasticity over time, cracks or becomes deformed. Even a microscopic gap leads to the constant replenishment of the chamber with a new portion of moisture.
Check the fit of the door around the entire perimeter. Often the problem occurs in the corners or around the hinges, where the rubber experiences maximum stress. Dirt and grease also interfere with tight closure, creating channels for air penetration.
- ❄️ Visually inspect the rubber for cracks and tears.
- ❄️ Wipe the seal with a soft cloth and soapy water.
- ❄️ Use the method “paper sheet”, clamping it with the door in a circle.
⚠️ Attention: If the seal is severely deformed, heating it with a hairdryer can only temporarily restore its shape. For reliable operation of the equipment Atlant it is better to replace the part with a new one.
It is important to consider that a skewed door may be a consequence of improper installation of the refrigerator. If the body is not level, gravity will pull on one side, opening a gap. Adjusting the legs often solves the problem without replacing spare parts.
Malfunctions of the defrost system (Defroster)
In models with a system No Frost or Low Frost automation is responsible for removing moisture. If a “beard” of ice has grown on the back wall, it means that the defrost cycle does not start or does not complete. The heating element, thermostat and timer are responsible for this process.
When the defrosting heating element burns out, the ice accumulated on the evaporator does not melt. Over time, the air channels become clogged, the cold stops circulating, and the refrigerator begins to wear out, trying to gain temperature. Moisture from the products settles on the first cold surface that comes across.
Diagnosis of this problem requires testing the elements with a multimeter. Often it is not the heater itself that fails, but the sensor, which “does not see” the ice and does not give the command to turn on the heating element. In older models Atlant the mechanical timer could be stuck.
How to check the heating element without disassembling?
It is difficult to carry out an accurate diagnosis, but an indirect sign is the hum of the compressor without pauses and the absence of characteristic crackling or clicking noises during defrosting, which can be heard if you put your ear to the back wall.
It should be remembered that regular accumulation of ice in the drainage system can also be caused by a breakdown of the defrost sensor. If it gives incorrect readings, the water does not have time to drain into the pan and freezes inside the case, gradually increasing the volume.
Clogged drainage hole
In refrigerators with a drip defrosting system, water should flow freely along the groove into the drainage hole. If this channel is clogged with crumbs, mold or ice, moisture remains inside the chamber and freezes on the back wall, forming snowdrifts.
Cleaning the drainage is one of the simplest procedures available to every user. It is enough to remove the decorative panel (if there is one) and carefully clear the passage. Often, a soft wire or a special brush is enough for this.
| Symptom | Probable cause | Solution method |
|---|---|---|
| Water on the floor under the refrigerator | The ice in the drainage has melted and the tray is overfilled | Clean the channel with warm water |
| Ice plug in the groove | Freezing of water in the channel | Thaw for 24 hours without power |
| Snow only at the bottom of the back walls | Partial blockage or misalignment | Align the refrigerator |
If after cleaning the problem returns after a week, the drain tube inside the case may be pinched or defective. In this case, a deeper disassembly of the rear part of the unit may be required to restore passability.

Improper operation and loading of products
Often users themselves create the conditions for snow formation, violating the operating rules. Hot food placed on a shelf sharply increases the humidity and temperature inside. The cooling system does not have time to remove excess moisture, and it settles with frost.
It is also important not to block the ventilation holes. Cold air should circulate freely. If products lie close to the back wall, they disrupt heat exchange, and the wall begins to freeze more than usual.
- 🥘 Do not place hot pots inside the chamber.
- 🥦 Step back 5-7 cm from the back wall when arranging.
- 🚪 Do not hold the door is open for longer than 30-40 seconds.
Particular attention should be paid to storing liquids in open containers. Water actively evaporates, increasing humidity. All liquids must be tightly capped. This rule is relevant for all models, be it budget Atlant 4008 or premium series.
⚠️ Attention: Frequently opening the door in the summer heat leads to instant condensation of moisture. Try to minimize the time when the camera communicates with the room.
Problems with the thermostat and sensors
If the thermostat “lies” and does not turn off the compressor on time, the refrigerator runs non-stop. The back wall becomes supercooled, turning into ice. In modern models, this is monitored by electronic temperature sensorswhich can also fail.
A symptom of a malfunction is the continuous operation of the motor. You can hear the compressor humming, but there are no rest cycles. In this case, a thick layer of snow grows on the wall, and the food deep in the chamber may even freeze.
Replacing a thermostat requires qualifications, since you need to accurately select an analogue with the same characteristics. Installing the wrong part will result in the refrigerator either not turning off or not being able to reach the desired temperature.
Sometimes the problem lies in a freon leak, although this is more often accompanied by insufficient cooling. However, at the initial stages or due to malfunctions of the control system, local freezing may be observed.
Methods of complete defrosting and prevention
If the snow is already frozen, no manipulation of the settings will help - complete defrosting is needed. Unplug Atlant from the mains, remove all food and leave the doors open for at least 24 hours. This is the only way to melt the ice in hidden channels.
After defrosting, thoroughly wipe the insides dry. Do not use sharp objects to chip ice - this is guaranteed to damage the evaporator and cause gas leakage. Let the ice melt naturally.
Regular prevention will extend the life of equipment. Every six months, check the cleanliness of the drainage and the condition of the seal. Timely maintenance is cheaper than replacing the compressor or evaporator.
Compliance with the temperature regime is also important. Do not set the regulator to maximum unless necessary. For basic food storage, a position corresponding to +4...+5°C is sufficient.
Why does snow appear in only one corner?
Local freezing often indicates a distortion of the refrigerator body or deformation of the seal in this particular area. It is also possible that the air flow is directed incorrectly due to the close proximity of the product.
Is it possible to use a hair dryer to speed up defrosting?
You can use a hair dryer with caution, directing warm air only at the ice, but not at the plastic parts and rubber seal. High temperatures can deform plastic. It is better to let the ice melt on its own.
Is it normal that the back wall is periodically covered with frost?
In refrigerators with a drip system (“crying wall”), the periodic appearance of a thin layer of frost, which then melts, is the norm of the operating cycle. You should sound the alarm if the layer does not melt or turns into a snow coat.
Does the humidity in the room affect the formation of snow?
Yes, high humidity in the room increases the amount of moisture entering the chamber when the door is opened. In wet weather, a snow coat can grow faster, requiring more frequent leak testing.
