The situation when Atlant refrigerator ceases to cope with its main function often takes you by surprise. Food begins to deteriorate, condensation appears on the walls, and the ice in the freezer melts faster than usual. Before calling a technician or looking for a new unit, it is worth understanding the reasons for the decrease in performance, since in many cases the problem can be solved on your own.
The first step should always be basic diagnostics the current state of the equipment. Often the reason lies not in a compressor breakdown or freon leak, but in a banal violation of operating rules or failures in the temperature control system. Understanding the operating principles of your model will help you quickly return Atlant refrigerator the required cooling power.
In this article we will analyze in detail the algorithm of actions that will help you lower the temperature inside the chambers. We will consider the settings of electromechanical and electronic control systems, check the tightness of the circuit and eliminate external factors affecting heat transfer. Carefully following the instructions will save time and budget for repairs.
Setting the thermostat and temperature settings
The most obvious, but often ignored reason is the incorrectly set temperature. In refrigerators Atlant with electromechanical control, a rotary handle, usually located inside the main chamber, is responsible for this. If the regulator is set to the minimum value (number 1 or “Min”), the compressor operates in a gentle mode, which may not be hot enough in the summer or when fully loaded with products.
It is necessary to turn the knob towards increasing the value, usually to the mark 3 or 4. This will cause thermostat to turn on the compressor more often and for a longer time, until the temperature inside reaches the specified threshold. However, you should not immediately turn the regulator to maximum, as this will lead to excessive freezing of the evaporator and increased load on the engine.
In models with a system No Frost and electronic control, settings are made through the display on the door or a hidden panel. Here it is important not to confuse the temperature in the refrigerator compartment (usually +3...+5°C) and in the freezer (-18°C and below). To enhance cooling, you should select the “Super Freeze” or “Max Cool” mode, which is activated for a limited time.
It is important to consider that after changing the settings temperature stabilization it takes time. The unit takes from 4 to 8 hours to reach a new operating mode, especially if the chambers were very hot or loaded with warm products.
Checking the tightness and condition of the seal
Even an ideally operating compressor will not be able to create a low temperature if the cold constantly evaporates outside. The main enemy of cold is leaky circuit. The rubber seal on the door loses its elasticity over time, cracks or deforms, allowing warm air to pass through. This forces the equipment to wear out, but does not give the desired result.
Carry out a visual inspection of the rubber around the entire perimeter. There should be no cracks, cuts or areas with mold, which often loosens the structure of the material. Pay special attention to corners and folds where wear occurs most quickly. Dirt and grease also prevent a tight fit, so the cleanliness of the seal is critically important.
☑️ Diagnosis of the seal
There is a simple and reliable way to check the tightness of the seal, known as the “paper test”. Take a regular sheet of paper, clamp it with the door and try to pull it out. If the sheet is easily removed without resistance at different points of the perimeter, it means that seal it does not fit tightly and requires replacement or restoration.
How to temporarily revive the seal?
If the rubber has simply lost its elasticity, but is intact, you can try heating it with a hairdryer (carefully, without overheating) or pouring a silicone tube into the voids. However, this is a temporary measure, and a complete replacement will still be required.
The influence of location and ventilation on cooling
Operating efficiency of the Atlant refrigerator directly depends on the conditions of its placement. The refrigeration unit does not produce cold, it transfers heat from the inside to the outside. If something interferes with this process, the temperature inside the chambers will begin to rise. The key factor here is correct air circulation around the rear wall and compressor.
Make sure that the distance between the rear radiator grille and the wall is at least 5-7 cm. If the refrigerator is built into a niche or standing close to furniture, the hot air has nowhere to go, and it returns back into the system, reducing efficiency. Also, you cannot place equipment closer than 10 cm to the side walls, if required by the instructions for a specific model.
It is strictly forbidden to place refrigeration equipment near heat sources: gas stoves, radiators, ovens or in direct sunlight. Local overheating causes the thermostat to think that it is warm inside, and the compressor works without interruption, but cannot cope with heat inflows from the outside.
⚠️ Attention: If your refrigerator is located in a niche of a kitchen unit, make sure that there is a ventilation system there (holes in the floor and ceiling of the niche). Without the influx of cold air from below and the exit of hot air from above, the equipment will quickly fail.
Check whether air access to the bottom of the case is blocked, where ventilation holes for cooling the compressor are often located. Dust and pet hair can clog these grilles, creating a “thermal blanket” effect.
System diagnostics defrost and ice
Excessive ice formation is another factor that interferes with normal cooling. A thick layer of “coat” on the evaporator acts as a heat insulator, preventing cold from penetrating into the chamber. In refrigerators with manual defrosting, frost can reach several centimeters if the need for maintenance is ignored for a long time.
In models with a system No Frost a special timer and heating element are responsible for defrosting. If this system fails, ice blocks the channels that allow cold air to enter the refrigerator compartment. As a result, it may be cold in the freezer, but warm in the upper compartment, or the temperature will be unstable throughout the entire volume.
If you notice that the back wall is overgrown with an uneven layer of ice or a “beard” of icicles, this is a signal of a malfunction. In such cases, complete defrosting is required. Unplug the appliance, open the doors and leave it for at least 24 hours (preferably two days) so that the ice completely melts and the water evaporates.
| Symptom | Possible cause | Action |
|---|---|---|
| Ice crust on the back wall | Faulty defrost sensor | Defrosting 24+ hours, call a technician |
| Icicles in the freezer | Poorly closed door | Checking the seal and products |
| Water on the floor | Clogged drainage hole | Cleaning the channel with a brush |
| Noisy fan operation | Ice on the blades | Complete defrosting of the unit |
After defrosting, thoroughly wipe the internal surfaces and drainage hole. Often it is a blockage in the condensate drainage channel that leads to water freezing in the wrong place and disrupting air circulation.
Loading food and organizing storage
Correct loading of cameras is not just a matter of convenience, but also a condition for effective operation Atlant refrigerator. Cold air should circulate freely between the products. If the shelves are packed to capacity and the products are placed close to the back wall, the temperature sensors may read incorrect data, and the cold will not be distributed evenly.
Never put hot or even warm foods in the chamber. This causes a sharp jump in temperature and humidity, which leads to the formation of ice and a temporary increase in the overall temperature inside. Allow the food to cool to room temperature before storing.
Pay attention to the location of food near the back wall. In most models Atlant this is where the crying evaporator or cold air outlet is located. The adhesion of products to this zone can lead to their spoilage (freezing) or, conversely, to local overheating of the sensor.
Technical faults that reduce refrigeration capacity
If all of the above methods did not help colderthe problem is probably due to a technical malfunction. The most common problem is a refrigerant (freon) leak. In this case, the compressor can hum almost non-stop, but no cold is generated. A leak often occurs in the foamed part of the housing or in the perimeter heating circuit.
Another possible reason is compressor failure. If one of the pistons is worn out or the valves do not hold pressure, the unit will not be able to create the necessary compression for efficient cooling. Only a master can diagnose this using a pressure gauge.
It is also worth mentioning that the capillary tube is clogged. An ice or grease plug may form in the freon circulation system, which blocks the flow of refrigerant. A symptom is often that the condenser (grid at the back) only partially heats up or remains cold.
⚠️ Attention: Attempts to replace freon yourself or solder tubes without special equipment and skills can lead to complete failure of the equipment and a fire hazard. Repairing a sealed circuit requires a license and tools.
In models with electronics, the cause may be a failure in the control module. The board may incorrectly read sensor readings and not give a command to turn on the compressor. In this case, a reboot helps (disconnect from the network for 15 minutes), but often replacement of electronic components is required.
When you need to call a technician
There are a number of signs indicating that self-setup temperature conditions will no longer help. If you have defrosted, checked the seal and settings, but the situation has not changed within 24 hours, it’s time to call the service center. Ignoring the problem can lead to spoilage of a large number of products.
An alarming signal is a change in the sound of the motor. If there is a metallic knock, a whistle, or, conversely, the engine starts and immediately stalls with a click, these are signs of a serious breakdown of the mechanical or electrical part. You should also call a specialist if traces of oil or swelling are visible on the back wall.
Timely contacting a specialist will save the life of the equipment. Modern Atlant refrigerators equipped with complex diagnostic systems, and professional repairs are often cheaper than buying a new unit after the breakdown has worsened.
Why does the Atlant refrigerator work, but does not freeze after defrosting?
If after complete defrosting (more than 24 hours), the refrigerator turned on, worked and stopped freezing; perhaps there was a freon leak or the capillary system was clogged. The compressor start relay could also be faulty. Diagnostics by a specialist is required.
What temperature should be set in the Atlant two-chamber refrigerator in the summer?
In the summer, when the ambient temperature in the room is high, it is recommended to set the thermostat to a value slightly above average (for example, 3.5-4 out of 7) to compensate for heat inflows, but not to overload the compressor to the maximum.
Is it possible to increase cooling by opening the freezer door?
No, this is a common misconception. Opening the freezer door for a long time will lead to freezing of the evaporator and moisture entering the No Frost system, which will ultimately worsen the cooling throughout the entire refrigerator.
What to do if it is +10°C in the refrigerator compartment, and the adjustment does not help?
Most likely, the problem is not in the settings. Check if the fan in the No Frost chamber is spinning (if any). If the fan is stopped, no cold comes in. It is also possible that the defrosting heating element circuit is broken or the temperature sensor is malfunctioning.
