Owners of refrigeration equipment of the Belarusian brand often encounter a situation when an ice crust begins to actively grow inside the chamber or on the back wall. This not only reduces the usable volume for storing food, but also creates an increased load on the compressor. Temperature violation can lead to rapid spoilage of inventory and a significant increase in energy bills. Understanding the physical processes occurring inside the unit will help to quickly identify the root of the problem.
Modern models Atlant with a system No Frost and classic two-chamber refrigerators with a drip system have different mechanisms for ice formation. In the first case, ice indicates a malfunction in the defrosting automation; in the second, it may be a consequence of a natural, but excessive process or a leak. Diagnostics requires a careful examination of the internal space and analysis of associated symptoms, such as noise or motor operating mode.
Before calling a technician or disassembling the unit, it is necessary to eliminate common operating errors. Often, users themselves provoke icing by incorrectly placing products or ignoring the rules for caring for seals. Systematic accumulation of ice more than 5 mm thick is a direct indication for diagnosing the defrost system or checking the tightness of the circuit. In this article we will analyze in detail all possible causes and ways to eliminate them.
⚠️ Attention: Before starting any diagnostic or repair work, be sure to disconnect the refrigerator from the power supply. Working with electrical appliances under voltage is dangerous to life!
Violation of the tightness of the door seal
One of the most common reasons why ice freezes in the refrigerator Atlant is the loss of tightness of the doorway. Rubber seal Over time, it loses elasticity, becomes deformed or becomes dirty, which is why the door does not fit tightly. Through the resulting cracks, warm, moist air from the room constantly flows into the chamber. Moisture condenses on cold surfaces and instantly turns into frost, which then grows in layers.
You can check the condition of the seal visually and tactilely. Pay attention to any cracks, creases, or areas where the rubber has pulled away from the body. A simple test with a sheet of paper will help determine the quality of the fit around the entire perimeter. If the paper falls out or is pulled out without resistance, there is a gap in that area. It is also worth inspecting the door itself for distortions that could occur due to loose hinges or overloading of shelves.
- 🔍 Conduct a visual inspection of the rubber for visible damage and dirt.
- 📄 Use a test with a sheet of paper, pressing it with the door at different points in a circle.
- 🌡️ Check the temperature of the seal after operating the refrigerator - it should be slightly warm, but the same along the entire length.
- 🚪 Make sure that the door closes tightly and does not bounce when pressed lightly.
If the seal is simply dirty, just wash it with warm water and a mild detergent means. In case of deformation, you can try to restore the shape using a hairdryer, gently heating the problem areas. However, if the rubber has cracked or become hard, it will be required replacing the seal. New parts for models Atlant are available in service centers and specialized stores.
Malfunctions of the defrost system in No Frost models
In refrigerators Atlantequipped with the system No Frostice should not form on the food or chamber walls in visible quantities. The evaporator, where moisture freezes, is hidden behind a plastic panel on the back wall. An automatic defrosting system is responsible for its periodic cleaning. If snow or an ice coat appears in the chamber, this is a direct signal that the defrosting cycle is broken.
The main elements of this system are the evaporator heating element, the thermostat (or defrost sensor) and the timer (or electronic control module). If any of these components fail, the ice stops melting at the right time and gradually clogs the drainage hole and air channels. As a result, cold air stops circulating, the temperature in the chamber rises, and the compressor works non-stop, trying to compensate for heat loss.
Diagnostics begins with a visual inspection of the evaporator. To do this, you will have to remove the back panel in the freezer. If there is a thick layer of ice visible and the drain hole is clogged, you need to check the defrost circuit. Most often, it burns out itself Heating element or the sensor fails, which does not give a command to turn on the heating. In models with a mechanical timer, the mode switch itself may jam.
☑️ Diagnostics of the No Frost system
Clogged drainage hole and gutter
In classic refrigerators Atlant with a drip defrosting system, water flows down the back wall into a special trench and then through the drainage hole is discharged into a container above the compressor, where it evaporates. If this path is blocked, the water does not leave, freezes and turns into an ice plug. Over time, the plug grows, blocking the exit of new water, which begins to accumulate at the bottom of the refrigerator or shelves.
The causes of blockages are often food particles, crumbs, mold or mucus formed in conditions of constant humidity. Even a small piece of food falling into the tube can become the center of ice crystallization. In winter, if the refrigerator is located on an unheated dacha or balcony, the water in the drainage may freeze due to the low ambient temperature, although this is also harmful for the operation of the unit itself.
To clean the channel, you can use a soft wire, a bottle brush or a special flexible brush. Mechanical impact on the tube must be done carefully so as not to pierce it and damage the internal circuit. An effective way is to rinse with warm water using a syringe or rubber bulb. The water pressure will help dislodge the plug and clear the walls of plaque.
⚠️ Attention: Do not use sharp metal objects (knitting needles, knives) to clean the drainage - there is a high risk of damaging the pipelines or breaking through the inner wall of the chamber, which will lead to freon leakage.
Problems with the thermostat and temperature sensors
Thermostat (thermostat) is a device that controls the temperature inside the chamber and sends a signal to turn the compressor on or off. If thermostat is faulty and “sticks” in the “on” position, the refrigerator will operate continuously. In chambers with a drip system, this leads to the fact that the back wall freezes through, and the moisture does not have time to drain, turning into ice.
In models with electronic control, the role of a thermostat is performed by air temperature sensors. Their readings may be distorted due to oxidation of contacts, broken wiring, or failure of the sensor element itself. If the sensor “lies” and shows that the chamber is warmer than it actually is, the controller will keep the compressor on longer than necessary.
Checking the thermostat in mechanical refrigerators Atlant is often carried out by the method of exclusion or testing the contacts with a tester when the temperature changes. Electronic models require diagnosing the control board and checking the resistance of the sensors. Sometimes the problem is solved by simply replacing the sensor, which is located in an accessible place inside the chamber.
How to check the thermostat without instruments?
Dip the thermostat sensitive tube (or the sensor itself, if it is remote) into cold water with ice. If the contacts do not open after a few minutes, the thermostat is faulty and requires replacement.
The effect of improper operation on icing
Often the cause of ice freezing lies not in a breakdown, but in the actions of the user himself. Violation of operating rules can negate the operation of even working equipment. For example, loading hot or warm products into the chamber leads to a sharp increase in humidity and intensive formation of condensation, which instantly freezes.
It is also important to consider the frequency and duration of opening the door. If the door is opened frequently or left open for a long time, a large amount of warm air enters the chamber. Moisture from this air settles on cold surfaces. In models Atlant with manual or drip defrosting, this can lead to rapid fouling of the back wall.
Another factor is the placement of products close to the back wall. In drip refrigerators there is a cooling element. If food touches the wall, it disrupts the flow of water and it freezes, forming ice. In addition, this interferes with proper air circulation.
| Factor | Consequence | Solution |
|---|---|---|
| Hot foods | A lot of condensation and ice | Cool food to room temperature |
| Open door | Intake of moist air | Make sure the closure is tight |
| Food against the wall | Block water drainage | Leave a gap of 3-5 cm from the wall |
| Rare defrosting | Ice crust build-up | Defrost 1-2 times a year |
When professional repair is required
If simple methods such as defrosting, clearing drains and checking the seal do not help, most likely the problem lies deeper. Failure compressor, refrigerant leak or malfunction of the electronic control module requires the intervention of a qualified specialist. Independent repair of complex components without special equipment and skills can lead to final breakdown of the unit.
Symptoms of serious malfunctions are: the compressor hums, but does not start; the refrigerator works around the clock, but does not freeze; gurgling sounds are heard in the pipelines; traces of oil are visible on the rear grille. In such cases, operation of the equipment should be stopped until the reasons are clarified.
The technician will conduct a full diagnosis, check the pressure in the system, the integrity of the electrical circuits and the tightness of the circuit. Replacing the heating element, thermostat or purging the system are standard procedures that restore functionality Atlanta. Remember that regular maintenance extends the life of the refrigerator.
⚠️ Attention: If you notice a burning smell or sparking in the area of the compressor or control board, immediately unplug the refrigerator and contact a service center. Further switching on is dangerous!
Is it possible to defrost the Atlant refrigerator with a hairdryer?
You can use a hairdryer to speed up defrosting, but with great caution. Direct the blow of warm, but not hot air onto the ice crust, avoiding contact with plastic parts and rubber seals, which can be deformed by high temperature. Do not use sharp objects to chip ice.
How often do you need to defrost a refrigerator with a drip system?
Refrigerators Atlant with a drip system (crying wall) require complete defrosting 1-2 times a year. Frequent defrosting is not required, as the system automatically removes condensate. However, if you notice that the layer of ice on the back wall becomes thick and does not have time to drain, defrosting should be done unscheduled.
Why did the ice appear again after a couple of days after defrosting?
If the ice appeared quickly, then the cause has not been eliminated. Most likely, one of the defrost system components (heating element, sensor, timer) is faulty or the door seal is broken. It is also possible that the drainage hole was not cleaned thoroughly enough and became clogged again.
Does the installation level of the refrigerator affect the formation of ice?
Yes, it does. If the refrigerator is not level, the door may not close tightly under its own weight. Typically, the front of the refrigerator should be slightly higher than the back so that the door closes automatically. Check the adjustment of the legs and the position of the body.
