Owners of refrigeration equipment of the Belarusian brand are often faced with a situation where excess ice forms inside the chamber. Atlant refrigerator it is famous for its reliability, however, even time-tested models can malfunction in the operation of the moisture removal system. If you notice that a coat of snow or a thick crust of ice has formed on the back wall, this is a signal that the balance between cooling and condensate evaporation is disturbed.
Ignoring the problem can lead to more serious consequences, including failure of the compressor or failure of the seals. Moisture, turning into ice, occupies a useful volume and changes the temperature regime of food storage. No Frost System or a drip defrosting system should work flawlessly, but external factors or wear of parts often make their own adjustments.
In this article we will analyze in detail why icing occurs, how to diagnose it yourself and how to In what cases will you need to call a specialist? Understanding the principles of operation evaporator will help you avoid unnecessary expenses on repairs.
The principle of operation of the moisture removal system and the causes of icing
To understand the nature of the problem, you need to understand the physics of the process. In refrigerators with a drip defrosting system, moisture from the air settles on the coldest surface - the back wall. There it turns into frost, which periodically thaws during pauses in the compressor. The flowing drops fall into the gutter and go through the drainage channel into a container above the motor, where they evaporate.
If this cycle is disrupted, the water does not have time to drain and freezes, forming an ice shell. In models with No Frost ice should not form on the walls at all, since there is a forced air circulation system and a separate evaporator, hidden from the user’s eyes. The appearance of ice in the chamber of such models is always a sign of a malfunction.
⚠️ Attention: If ice appears suddenly after a long period of normal operation, remember whether you changed the location of the products or the temperature settings the day before.
Often the cause is a banal violation of operating rules, which are forgotten over time. Condensation not has time to evaporate if too much warm air or moisture enters the chamber. This can happen when doors are frequently opened or hot dishes are placed inside.
Violation of the rules of operation and placement of products
The most common reason for ice freezing lies not in the breakdown of equipment, but in the actions of the user. Food placed in the refrigerator contains moisture, which evaporates and settles on the walls. If the air circulation inside the chamber is disrupted, moisture cannot be effectively removed by the system.
Particular attention should be paid to product packaging. Open containers with liquids, soups without a lid, or wet vegetables in bags actively release moisture into the air. Humidity inside the chamber increases sharply, and the drainage system can no longer cope with the volume of condensate, which leads to the formation of ice.
- ❄️ Do not put hot or warm foods - this causes a sharp jump in humidity and temperature.
- ❄️ Close pots and containers with liquid food tightly with lids or cling film.
- ❄️ Regularly check the integrity of the packaging of vegetables and fruits so that they do not ooze.
It is also important to do it correctly place products against the back wall. If you move pots or bags close to the back panel, you will block cold access to the temperature sensor and disrupt heat transfer. In this place, the temperature will be lower than the set one, which will provoke active freezing of moisture.
Another factor is frequent and prolonged opening of doors. When warm air gets inside, it contains a lot of moisture. Upon contact with cold walls, it instantly condenses and freezes. If the room where it is located Atlant refrigeratorhas high air humidity, the problem is aggravated.
Problems with sealing rubber and tightness
The tightness of the refrigeration chamber is a key factor in stable operation. The rubber seal (cuff) located around the perimeter of the door is responsible for this. Over time, the material loses its elasticity, cracks or deforms, no longer fitting tightly to the body.
If warm air is constantly sucked in through leaks, the cooling system works in increased mode, trying to compensate for heat loss. The back wall freezes, and moisture from the incoming air turns into ice. You can check the condition of the seal visually and tactilely.
Do a simple test: close the door by holding a sheet of paper in different places. If the sheet pulls out too easily without resistance, the seal is poor. Also inspect the rubber for cracks, tears or contaminants that interfere with tight contact.
| Symptom | Probable cause | Remedy method |
|---|---|---|
| Ice on one side only | Door misalignment or deformation of the elastic | Adjusting the hinges or replacing the seal |
| Ice around the entire perimeter | Contamination of the elastic or wear of the material | Cleaning or replacing the cuff |
| The door is not slams | Foreign object or overflow | Removing the obstacle |
In some cases, the rubber band is simply contaminated with grease or crumbs. Thorough washing with warm soapy water can restore its properties. If the material is dull or torn, it will be required replacement of the seal, since gluing in this case will not give a durable result.
Faults in the temperature sensor and thermostat
If everything is in order with the tightness and operating instructions, The reason may lie in the electronics. The thermostat or temperature sensor controls the operation of the compressor. They give a command to turn the motor on and off depending on the temperature inside the chamber.
If the sensor fails or the thermostat contacts stick, the compressor may not turn off on time. The chamber freezes, and all the moisture turns into an ice crust. In models with electronic control, an error code often lights up or the indicator flashes.
Diagnosis of this malfunction requires special knowledge and equipment. You can only check on your own whether the settings are correct. Try changing the temperature mode by setting a lower temperature, and monitor the system's reaction.
⚠️ Attention: Do not try to disassemble the control unit yourself or change sensors without disconnecting the device from the network. This can lead to electric shock.
If the refrigerator works without interruption for days, and a huge lump of ice grows on the back wall, most likely the problem is in the “brains” of the device or the actuator of the regulator. In this case, a professional diagnostics and replacement of the faulty element is required.
Clogged drainage hole and drainage system
In refrigerators with a drip defrosting system, the condition of the drainage hole is critically important. It is located at the bottom of the back wall, often hidden by a plastic box. Through it, melt water goes into the tray above the compressor.
Over time, crumbs, mold or grease accumulate in the hole, forming a plug. The water cannot escape, accumulates in the gutter and freezes. Gradually, the ice completely blocks the outlet, and moisture begins to spread throughout the chamber, freezing on the shelves and products.
☑️ Cleaning the drainage
For cleaning, do not use sharp metal objects that can damage the tube or pierce the wall. It is best to use a special flexible brush or soft wire with a blunt end. After mechanical cleaning, it is recommended to rinse the channel with warm water from a syringe.
If after defrosting and cleaning the problem returns after a short time, the drainage channel itself inside the housing may have frozen or the tray has moved. This is a more complex malfunction that requires partial disassembly of the rear panel of the refrigerator.
Full defrosting as a method of primary diagnosis
Before calling a technician or buying new parts, experts recommend carrying out a complete defrosting. This simple action often helps eliminate malfunctions in the automation and clean the system naturally.
To do this, you need to completely disconnect the refrigerator from the power supply, empty the chambers of food and leave the doors open. The minimum defrosting time for Atlant refrigerators is 24 hours, although the instructions may require less. During this time, all the ice, including that hidden in the evaporator, will have time to melt.
During defrosting, thoroughly wash the internal surfaces and check the drainage hole. After turning on, let the device work for 2-3 hours without loading food so that it reaches the desired temperature.
Why can’t you scrape off ice with a knife?
Mechanical removal of ice with sharp objects is strictly prohibited. You may damage the evaporator sealed into the wall. The release of freon will lead to expensive repairs or disposal of the refrigerator.
If, after complete defrosting, ice on the back wall appears again within a day or two, then the problem is of a technical nature and requires the intervention of a specialist. If the refrigerator works normally for several weeks, the reason was overload or rare defrosting.
When you need to call a technician and professional repairs
There are a number of symptoms in which self-repair is not only ineffective, but also dangerous. If you observe these signs, it is better not to experiment with the equipment.
- 🛠️ The compressor hums continuously without pausing, and the temperature in the chamber drops below -20°C.
- 🛠️ A burning smell has appeared or the crackling sound of electrical discharges has been heard.
- 🛠️ Ice has formed in models with the No Frost system, where it should not be.
In such cases, replacement compressor, refrigerant refilling or repair of the control board may be required. These works are carried out only in a service center using special tools.
A specialist’s help is also needed if the seal circuit or evaporator is damaged. Attempts at self-repair in these cases can lead to permanent failure of the unit. Remember that timely contact with professionals often saves your budget in the long run.
Why does ice appear only after the door is opened?
This is a classic sign of a loose seal or opening the door too often. Warm, moist air instantly condenses on the cold back wall. Check if anything is preventing it from closing tightly, and make sure that the shelves are not overloaded.
Is it possible to speed up defrosting with a hair dryer?
Using a hair dryer is only permissible at a minimum temperature and from a long distance. Sudden temperature changes can damage the plastic and internal components. It is better to be patient and defrost naturally, so as not to cause cracks in the evaporator.
How often do you need to defrost the Atlant refrigerator?
Even systems with drip thawing require preventive defrosting 1-2 times a year. This helps remove odors, disinfect surfaces, and clear drainage. No Frost models do not need frequent defrosting, but general cleaning will not hurt them either.
