The situation when the refrigerator Atlant stops cooling food efficiently, often takes you by surprise. It becomes warm inside the chamber, the ice in the freezer melts, and condensation appears on the walls. This is a signal that a failure has occurred in the refrigerant circulation system or in the electronic control.
Many owners of Belarusian equipment are faced with the fact that the unit works without interruption, but there is no desired cold. In other cases, the compressor, on the contrary, is silent, although the light is on. Understanding the root of the problem will help you avoid expensive repairs or damage to a large supply of food.
In this article we will analyze in detail the main reasons why the refrigerator Atlant does not freeze well. We will consider both simple operating errors that you can correct yourself, and complex technical malfunctions that require the intervention of a specialist.
Incorrect installation and operation of equipment
Before you panic and look for breakdowns, it is worth eliminating trivial factors. Often the reason that the refrigerator Atlant cools poorly lies in a violation of the installation rules. If the equipment is placed close to the wall or in a niche without gaps, heat exchange is disrupted.
The compressor overheats and cannot create the necessary pressure in the system. It is also important to check whether the unit is located too close to heat sources, such as radiators or gas stoves.
⚠️ Attention: Installing the refrigerator less than 5 cm from the wall is guaranteed to overheat the condenser and reduce cooling efficiency.
Another critical point is the loading density of the chambers. If you've packed your shelves to capacity, the air simply can't circulate. In systems No Frost this is especially important, since the cold flow is blocked by food.
Check the position of the temperature regulator. Perhaps someone in the household accidentally moved a knob or changed settings in a digital menu. For normal operation, the middle position is usually sufficient.
Malfunctions of the thermostat and temperature sensors
If the refrigerator Atlant hums, but does not freeze, or, conversely, turns off too early, the problem may be in the thermostat. This element is responsible for turning the motor on and off depending on the temperature inside the chamber.
Mechanical models use a capillary tube, which loses sensitivity over time. In electronic models, sensors (thermistors) are responsible for this. If the sensor is lying, the control board does not give a command to start the compressor.
Symptoms of a thermostat failure can be different:
- ❄️ The refrigerator does not turn on at all, although the light is on.
- ❄️ The unit works non-stop, turning the chamber into glacier.
- ❄️ The operating cycles are too short, the products do not have time to cool.
Replacing the thermostat is a procedure accessible to experienced users, but requires care. It is important to choose the right analogue, since the on/off parameters for different models Atlant may differ.
How to check the thermostat with a multimeter?
To check a mechanical thermostat, you need to remove it and “ring” the contacts with a multimeter. When the sensor is cooled (for example, in a freezer), the contacts should close. If the circuit does not close even in cold weather, the part is faulty. However, only a specialist can make an accurate diagnosis, taking into account the electrical circuit of your model.
Problems with the compressor and start relay
The heart of any refrigerator is the compressor. If the refrigerator Atlant does not cool well, and the motor works intermittently, hums or clicks, it is worth checking the starting relay and the engine itself.
The starting relay is a small block that provides an impulse to start the motor. Over time, the contacts inside it burn out, or the bimetallic strip loses its properties. As a result, the compressor tries to start, clicks and is switched off by the protection.
A more serious problem is the wear of the compressor itself. If the piston group has exhausted its life, the unit will not be able to create the required pressure, even if it operates around the clock. In this case, the refrigerator will be barely warm.
Signs of problems with the motor-compressor:
- 🔊 Loud knocking or clanging when starting.
- 🔊 The motor is hot to the touch, but does not start.
- 🔊 A beep is heard, but there is no cold.
Refrigerant leak and clogged capillary tube
One of the most common reasons why a two-chamber refrigerator Atlant stops freezing is a freon leak. The refrigerant circulates in a closed circuit, but over time, microcracks may form at the soldering points or in the evaporator.
The gas evaporates and the pressure in the system drops. The compressor works, trying to compensate for the shortage, but there is no cold. Sometimes the leak is accompanied by the appearance of oily stains on the floor under the unit.
Another common one is a clogged capillary tube. An ice plug (due to moisture) or blockage with oil breakdown products could have formed in the system. This blocks the circulation of freon.
Symptoms of a leak or blockage often manifest themselves specifically:
- 🧊 The freezer is working normally, and the refrigerator compartment is warm.
- 🧊 The condenser (grid at the back) only heats up partially.
- 🧊 Uneven frost or swelling is visible on the evaporator.
⚠️ Attention: Self-charging with freon is impossible without special equipment and a vacuum pump. Trying to simply “add gas” without eliminating the leak will only temporarily hide the problem.
Comparison of faults: diagnostic table
To make it easier for you to navigate the symptoms, we have prepared a summary table. It will help determine the direction of troubleshooting in the refrigerator Atlant.
| Symptom | Probable cause | Difficulty of repair |
|---|---|---|
| The compressor does not turn on, there is light | The thermostat or relay is faulty | Low / Medium |
| The motor hums, clicks and turns off | Start relay or compressor wedge | Medium |
| Works constantly, but there is not enough cold | Freon leakage or system blockage | High (needs a technician) |
| The refrigerator is covered with a “coat” of ice | The door is not tightly closed or the heating element is burnt out defrosting | Average |
As can be seen from the table, some problems can be solved by replacing an inexpensive part, while others require calling a specialist with equipment. Diagnostics it begins with analyzing the behavior of the unit.
Failures in the defrost system (for No Frost models)
In refrigerators Atlant with the No Frost system for A complex defrost unit is responsible for heat removal and moisture removal. If it fails, the evaporator becomes overgrown with ice, which blocks the air channels.
As a result, the cold simply does not enter the chambers. The fan may hum, but there will be no airflow. Often in such cases, the freezer still keeps cold, and the refrigerator compartment defrosts.
The main elements of the system that can fail:
- Defrost heating element (heating element).
- Defrost sensor (thermostat).
- Timer or electronic defrost control module.
To check, you need to remove the back panel in the freezer. If you see a thick layer of ice on the evaporator, and the fan rests against it or barely spins, the problem is here.

When you need to call a specialist
Despite the desire to save money, there are situations when DIY repairs are impractical or dangerous. If you have checked the thermostat and relay, but the refrigerator Atlant still does not freeze, most likely the problem is in the sealed circuit.
To find leaks, replace the filter-drier and refill with refrigerant, a license and professional tools are required. In addition, improper soldering can lead to a fire or complete failure of the compressor.
It is also worth contacting the service if:
- 🛠️ The compressor needs to be replaced (soldering and vacuuming are required).
- 🛠️ A breakdown has occurred insulation (noticeable electric shocks when touching the case).
- 🛠️ The electronic control board has burned out (re-flashing or complex soldering is required).
⚠️ Attention: When working with the electrical components of the refrigerator, always disconnect the device from the network. The capacitors on the board can retain their charge even after being turned off.
Timely contacting professionals is often cheaper than trying to revive a “stuck” compressor using traditional methods. Remember that the service life of equipment Atlant directly depends on operating conditions and quality of service.
Is it worth repairing an old Atlant?
Repair is advisable if the cost of spare parts and labor is less than 50% of the cost of a new analogue. For models older than 10-12 years, it is often cheaper to buy a new refrigerator, since the life of the remaining components is also coming to an end.
Frequently asked questions (FAQ)
Why does the Atlant refrigerator work non-stop and does not turn off?
Most often this indicates a freon leak. The compressor tries to compensate for the lack of refrigerant by constantly working. Also, the reason may be a stuck thermostat or a broken door seal.
What to do if it is warm in the refrigerator compartment and ice in the freezer?
This is a classic sign of a malfunction of the defrost system (for No Frost) or a freon leak. In two-compressor models, one of the compressors or the thermostat of the refrigeration compartment could fail.
Is it possible to replace freon in the refrigerator yourself?
No, this is impossible without specialized equipment (vacuum pump, pressure gauge station, scales). In addition, different models require a strictly defined type and amount of refrigerant.
How often do you need to defrost the Atlant refrigerator?
Models with manual defrosting require the procedure 1-2 times a year. Full No Frost systems do not require defrosting, but a preventive shutdown for a day every 2-3 years is useful for removing odors and checking components.
