The detection of a thick ice crust inside the refrigeration equipment chamber is not just an aesthetic defect, but a signal of serious malfunctions in the system. If you notice that snow or ice is heavily frozen in your Atlant refrigerator here, you cannot ignore this phenomenon, as this leads to increased energy consumption and accelerated wear of the compressor.
Modern models of the Belarusian brand are equipped with a No Frost system, which should prevent the formation of ice, but even in them, not to mention classic drip systems, failures can occur. Owners are often faced with a situation where the back wall becomes overgrown with a “fur coat”, and products freeze to the shelves, which makes access to them difficult and spoils the packaging.
In this article we will analyze in detail the technical and operational reasons for the problem. We will consider both simple errors in use that can be corrected independently in five minutes, as well as complex breakdowns that require the intervention of a specialist or replacement of parts.
Violation of tightness and problems with the seal
One of the most common reasons why ice freezes in the Atlant refrigerator is the loss of the seal of the chamber. Warm, moist air from the room constantly penetrates inside, where it instantly condenses and freezes, forming a dense layer of frost. Primary diagnosis begins with a visual inspection of rubber seal the door.
Over time, the rubber loses its elasticity, cracks or deforms, especially in the corners of the door leaf. If the seal does not fit tightly to the body, a gap is formed through which there is a constant flow of moisture. In models with No Frost this leads to rapid clogging of the drainage channel, and in drip systems - to the formation of huge icicles.
⚠️ Attention: Never try to forcefully slam the door if the seal is frozen or deformed. A sharp mechanical impact can permanently damage the fasteners or the rubber itself.
To check the tightness, you can use a simple paper sheet. Clamp it with the door in different places around the perimeter. If the paper is pulled out easily without resistance, then the contact has been broken in that area. It is also important to check the hinges: if the door is skewed, a tight fit cannot be achieved even with a new seal.
- 🔍 Visual inspection of the rubber for cracks and tears.
- 📄 Test with a paper sheet along the entire perimeter of the door.
- 🚪 Checking the evenness of the door installation and operation of the hinges.
- 🧹 Cleaning the contact surface from crumbs and grease.
Malfunctions of the defrost system in No Frost models
If your Atlant is equipped with the No Frost system, but ice still appears, the problem lies in the automatic defrosting cycle. In a working device, the frost that accumulates on the evaporator should be thawed regularly thanks to the heating element. The water flows into the pan and evaporates. A failure in this circuit leads to the evaporator becoming overgrown with ice, which blocks the cold air supply channels.
The key element here is Defrost heating element. If it burns out, the ice does not melt, but accumulates. Over time, the block of ice reaches the fan, which begins to hum or stops completely. As a result, the cold stops circulating through the chamber, the food spoils, and ice appears on the back wall.
The defrost sensor or timer (in old models) / electronic control module (in new ones) also often fails. The sensor must inform the control unit about the evaporator temperature. If he “lies”, the command to turn on the heating simply does not arrive. Diagnosis of these elements requires a multimeter and partial disassembly of the rear panel of the freezer.
Symptoms of a defrosting heating element failure
The refrigerator hums louder than usual, the fan may make a cracking sound when hitting the ice. The chamber may be warmer than set, despite the compressor running.
It is important to note that some Atlant modifications use the “Crying Evaporator” system in the refrigeration chamber and the No Frost system in the freezer. If ice freezes in the upper compartment, the problem may not be in the heating element, but in a clogged drainage hole, which we will discuss below.
Clogged drainage hole and moisture drainer
In refrigerators with a drip defrosting system (when the rear wall of the refrigerator compartment is periodically covered with condensate), the condition of the drainage channel is critically important. Water should flow freely into the tray above the compressor. If debris, mold, or food particles accumulate in the hole, a plug forms.
The blocked water does not flow out, but accumulates in the groove and freezes. An ice plug forms, which grows upward and to the sides, capturing shelves and products. In the Atlant freezer with No Frost, the drainage channel can also become clogged with ice chips or fluff, which will lead to water leaks into the chamber or under the refrigerator.
For cleaning, you can use a special soft brush wire or a regular cotton swab, carefully pushing it into the hole. It is strictly forbidden to use sharp metal objects, as you can damage the thin walls of the channel or pierce the evaporator, which will lead to freon leakage.
☑️ Cleaning the drainage
Incorrect setting of temperature and operating modes
Often users themselves provoke freezing by setting incorrect settings. If you set the minimum temperature (mode Super Freeze or “Maximum cold”) and forgot to switch back, the compressor will work without stopping. Moisture from the air will actively condense and freeze on the coldest surfaces.
The optimal temperature in the main chamber should be from +2 to +5 degrees Celsius. In the freezer - about -18 degrees. Lower values have no practical meaning for storing ordinary products, but significantly increase the load on equipment and contribute to ice freezing.
| Operating mode | Temperature | Impact on ice | Recommendation |
|---|---|---|---|
| Standard | +3...+5°C | Normal condensation formation | Main mode |
| Eco / Minimum | +5...+7°C | Almost no ice formation | For small loads |
| Max. cooling | 0...+2°C | Active freezing of the “fur coat” | Only for quick freezing |
| Super Freeze | -24°C and below | Extensive icing | No more 24-48 hours |
It is also worth mentioning that the chamber is loaded with warm products. If you put a pot of hot soup in the refrigerator, the humidity inside will increase dramatically. The system will not have time to quickly remove this moisture, and it will settle on the walls in the form of frost. Always allow food to cool to room temperature before storing.
Failure of the thermostat or temperature sensor
The thermostat (thermostat) is the “brain” that decides when to turn on and when to turn off the compressor. If this element fails and “sticks” in the “on” position, the refrigerator will freeze indefinitely. As a result, the temperature will drop below zero even in the refrigerator compartment, and the entire contents will be covered with a crust of ice.
In Atlant electronic models, air sensors are responsible for this. If the sensor is faulty or its contacts are oxidized, the control module receives incorrect data about the temperature in the chamber. The control unit “thinks” that there is a lot of heat and does not give a command to stop the engine.
Diagnostics of a mechanical thermostat is often carried out by exclusion or by testing with a tester at different temperatures. If the contacts do not open when the capillary tube cools, the part must be replaced. Self-replacement requires care so as not to damage the new capillary tube.
⚠️ Attention: When replacing the thermostat, it is important to correctly install and secure the sensing capillary tube. Loose contact with the evaporator will lead to incorrect operation of the new regulator.
The influence of humidity and frequency of door opening
The microclimate in the room also plays a role. If the Atlant refrigerator is in the kitchen, where soup is constantly being cooked, kettles are boiling or laundry is being dried, the air humidity is off the charts. Each time the door is opened, air saturated with moisture enters inside, which instantly turns into frost on cold surfaces.
Frequent and prolonged opening of doors aggravates the situation. You are looking for a product, the door is open for a minute or two - during this time a significant amount of air in the chamber has time to renew itself. In the summer, when the temperature difference between the street and the refrigerator is maximum, the effect is enhanced.
To minimize freezing:
- ❄️ Try not to keep the door open for more than 30-40 seconds.
- 🍲 Cover liquid foods with lids or film.
- 🌡️ Ventilate the kitchen, reducing the overall humidity.
- 🚫 Avoid installing the refrigerator near the stove or radiator.
When professional repairs are required
There are a number of symptoms indicating that the problem cannot be solved on your own. If, after complete defrosting (at least 24 hours with the doors open) and correct settings, ice appears again within 2-3 days, the problem is in the hardware.
Alarm signals to call a technician:
- The compressor runs continuously, without turning off for hours.
- Fan in the freezer makes a grinding or humming noise.
- Blisters or traces of oil are visible on the back wall (a sign of a freon leak).
- The electronic display shows error codes (for example, F or flashing indicators).
Independent repair of complex components, such as replacing a compressor, sealing a filter drier or searching for a refrigerant leak requires special equipment and a license. An attempt to do this without skills can lead to the final failure of the equipment.
Prevention of ice formation
So that your Atlant serves for a long time and was pleased with the lack of ice, take preventive measures. Regularly, at least once every six months, check the cleanliness of the drainage hole and the condition of the seal. Wipe the rubber cuff with a dry cloth, removing sticky residue.
Do not forget to defrost the refrigerator if you have a model with manual defrosting or a drip system. Even if the manufacturer writes that defrosting is not necessary, it is recommended to turn off the device once every year or two for complete drying and hygiene. This will extend the life of the thermal insulation and prevent the appearance of unpleasant odors.
Monitor the room temperature. If the refrigerator is in an unheated garage or on a balcony at a temperature below +10°C, the oil in the compressor may thicken and the sensors may not work correctly, which also indirectly affects operating modes and freezing.
Why does ice freeze on only one side?
Local freezing often indicates that the thermal insulation of the body is damaged in this place or there is a microcrack through which air is sucking. This may also be a sign of uneven air circulation due to an ice-clogged air duct.
Is it possible to speed up defrosting with a hair dryer?
You can use a hair dryer, but with extreme caution. Direct the stream of warm (not hot!) air only at the ice, avoiding contact with plastic parts and rubber seals, which can become deformed due to high temperature. It is better to use natural defrosting.
Does the amount of food in the chamber affect the formation of ice?
Yes, it does. An empty refrigerator will heat up faster when the door is opened because there is little “thermal mass” there. However, if there are too many products and they block the ventilation holes, circulation is disrupted, which also leads to local freezing.
What to do if the boxes are frozen?
Under no circumstances pull the boxes with force - the plastic will burst. Turn on the quick defrost mode or simply turn off the refrigerator. You can carefully pour warm (not boiling water!) water into the cracks between the box and the wall to melt the ice.
