The situation when Atlant refrigerator stops cooling often takes you by surprise, threatening food spoilage. Owners of Belarusian brand household appliances value them for their reliability, but even time-tested units can fail. Before calling a technician or looking for a service center, it is necessary to carry out an initial diagnosis to understand the scale of the problem.
Often the reason for the lack of cold is trivial things: voltage drops in the network or incorrect installation of the unit. However, if the equipment hums, but the temperature inside the chamber does not drop below room temperature, there may be a serious malfunction compressor or a refrigerant leak. In this article we will analyze in detail all possible causes and ways to eliminate them.
It is important not to panic and check each system one by one. Diagnostics it starts with simple steps that any user can perform without a special tool. Only after excluding external factors, it is worth moving on to the analysis of internal components.
Primary diagnostics and external factors
The first thing to do if you notice that The Atlant refrigerator does not freezeis to check the power supply. Make sure that the plug is firmly inserted into the outlet and that there is light in the room itself. Sometimes the problem lies not in the equipment, but in broken machines or a faulty socket.
Pay attention to how long ago the defrosting was done. If you just washed the unit and turned it on, temperature conditions it will not install immediately. It may take from 2 to 8 hours to set the required values, especially if there are a lot of products in the chambers.
It is also worth checking the tightness of the door. If sealing rubber band it is worn out or dirty, cold air will evaporate, and warm air will constantly flow inside. In this case, the compressor will work without interruption, trying to compensate for heat loss, but the desired effect will not be achieved.
⚠️ Attention: If the door does not close tightly due to skewed hinges, products may block the closing mechanism. Free up space at the opening.
Faults in the No Frost defrosting system
In models with a system No Frost or Full No Frost a frequent reason for the lack of cold is a failure in the defrosting system. An ice coat is growing on the evaporator, which is hidden behind a plastic panel. The fan stops moving air, and the cold does not enter the chamber.
The key elements here are the defrost heating element, the defrost thermostat and the timer (or electronic control module). If one of these components fails, the defrost cycle will not start. Ice blocks the air channels, and air circulation stops completely.
Checking often requires partial disassembly of the rear wall of the freezer. You can visually estimate the amount of ice. If there is a huge piece of ice on the evaporator and the sensors are “silent”, most likely the heating element has burned out or the sensor is stuck.
☑️ Checking the No Frost system
Interestingly, in some cases the problem is solved by completely defrosting the unit in the off state for 24 hours. If after switching on the cold appeared, but a week later the situation repeated itself, the defect is definitely in the elements of the defrost system.
Problems with the compressor and start relay
Compressor is the heart of the refrigerator. If it does not start or operates intermittently, there will be no cooling. Often the culprit is the starting relay, which provides an impulse to start the engine. When it breaks, a characteristic click is heard, followed by silence or a buzzing sound that turns into a click.
Replacing the relay is a simple and inexpensive procedure. However, if after replacement the situation has not changed, and the compressor itself is hot and hums, but does not start, a wedge in the mechanical part of the motor or an interturn short circuit of the winding is possible.
| Symptom | Probable cause | Solution |
|---|---|---|
| Clicking and silence | Faulty start relay | Replacement of relay |
| Humming and heating | Compressor wedge | Replacement compressor |
| Works without stopping | Freon leak | Searching for leaks, refilling |
| No response | Open circuit or module | Electrical repair |
It is important to note that inverter compressors, which are found in new Atlant models, are diagnosed differently. They do not emit characteristic clicks when starting, but smoothly gain momentum. To check them, special equipment is required.
⚠️ Attention: Replacing the compressor yourself requires evacuation of the system and charging with freon. It is impossible to do this efficiently without a pump and scales.
Refrigerant leak and capillary tube clogged
If Atlant refrigerator works constantly, the compressor is hot, but there is no cold, there is a high probability of freon leakage. The refrigerant can escape through microcracks in the foamed part of the housing or through solder joints. It is difficult to notice this visually, since freon is colorless and odorless.
Another common problem is clogged capillary tube. In the refrigerant circulation system, the passage for the substance becomes clogged, often due to moisture or oil breakdown products. The pressure in the system drops and cooling stops.
Only a master with a pressure gauge manifold can diagnose these faults. It connects to the system, measures the pressure and determines whether there is freon inside and what its circulation is. You cannot “pump up” the gas yourself - this is only a temporary measure.
Why can’t you just add freon?
If there is a leak in the system, adding gas without finding and fixing the hole will only have an effect for a few days or weeks. In addition, mixing different types of freon or air entering the system can permanently damage the compressor.
A symptom of blockage is often that the condenser (grid at the back) is only partially warm or cold, and freezing may occur in the area of the filter-drier.
Malfunction of the thermostat and sensors
Responsible for maintaining the temperature in the chambers thermostat (in mechanical models) or air sensors (in electronic ones). If the thermostat is “stuck” in the “Off” position, the compressor simply will not receive a signal to start.
In models with electronic control temperature sensors transmit signals to the control module. If one of the sensors fails, the controller may receive incorrect data and not start the cooling cycle, “thinking” that the cold has already been reached.
You can check the mechanical thermostat by closing its contacts. If after this the compressor starts working, the regulator needs to be replaced. Electronic sensors are checked with a multimeter for changes in resistance when the temperature changes.
Errors in operation and placement
Sometimes the answer to the question why the refrigerator does not coollies in a violation of the operating rules. The unit should stand at a distance of at least 5-7 cm from the wall. If the condenser is pressed against the wall, heat is not removed and operating efficiency drops.
Camera loading also matters. If you put a large amount of warm food in the refrigerator, it will take a long time to reach normal mode. Likewise, if the chambers are jam-packed, air circulation is disrupted. Frequently opening the door in a hot room creates excess load on the system. In the summer, when the ambient temperature is high, the refrigerator works more intensely, and older models may not be able to cope with the heat influx. air circulation.
Frequently opening the door in a hot room places excessive stress on the system. In the summer, when the ambient temperature is high, the refrigerator works more intensely, and older models may not be able to cope with the heat flow.
⚠️ Attention: Do not install the refrigerator next to heating appliances or in direct sunlight. This critically affects the life of the compressor.
Frequent questions and answers (FAQ)
Why does the Atlant refrigerator hum, but does not freeze?
Most likely, the compressor is working, but the refrigerant does not circulate through the system. This may be caused by a freon leak, a clogged capillary tube, or a malfunction of the compressor itself (for example, lack of compression). A failure in the No Frost defrosting system is also possible.
How long does the Atlant refrigerator need to reach the temperature after switching on?
Usually, it takes from 2 to 6 hours to initially reach the mode, depending on the model and the ambient temperature. If after 8-10 hours the temperature in the main chamber is above +10°C, and in the freezer is above -10°C, you should sound the alarm.
Is it possible to operate the refrigerator if it does not freeze?
For a short time - yes, for diagnostics. But long-term operation without cold is harmful to the compressor, especially if the cause is a freon leak (oil does not return to the motor) or a malfunction of the defrost system (the risk of burning out the heating element or fan).
What to do if there is ice in the freezer and heat in the refrigerator?
This is a classic sign of a malfunction of the defrosting system in No Frost models. An ice plug is blocking the cold supply channels. Try defrosting the refrigerator completely (24 hours). If the problem returns, you need to replace the heating element, sensor or timer.
Why is the back wall of the Atlant refrigerator warm, but there is no cold?
A warm back wall (condenser) indicates that the compressor is working. If there is no cold, it means that heat is removed, but there is no cooling capacity. This indicates a freon leak or lack of refrigerant circulation within the system.
