Modern household appliances require careful attention to settings, especially when it comes to food safety. Refrigerators Atlant are famous for their reliability, but even they need periodic adjustments to the operating mode. Users often encounter a situation where food in the main chamber begins to freeze or, conversely, quickly deteriorates due to insufficient cold.
Correct temperature adjustment not only extends the shelf life of food, but also saves energy, reducing the load on the compressor. In this article, we will analyze all the nuances of setting mechanical and electronic thermostats, and also eliminate typical errors made during operation.
The principle of operation of the thermostat in different models
Before you start manipulating knobs or digital panels, you need to understand how exactly your refrigerator controls cold. Most models Atlant use a mechanical thermostat that responds to changes in temperature inside the evaporator. When the air heats up to a certain threshold, the contacts close, starting the compressor.
Electronic control systems found in newer series operate on a different principle. Here, sensors constantly transmit data to the control unit, which itself makes decisions about turning the motor on and off. Accuracy there are much more such systems, which allows you to maintain the climate in the chamber with minimal fluctuations.
It is important to distinguish between these two types, since the methods for setting them are radically different. Mechanics require “selection” of the position of the handle empirically, while electronics allows you to set precise degrees. Errors in setting the mechanical regulator can result in the refrigerator working without interruption, trying to reach an unattainable temperature.
Location of temperature controls
Finding the control is the first step to success. In classic two-chamber models Atlant with one compressor, the regulator is most often located inside the refrigeration chamber. Usually this is a round handle with divisions or a slider located on the right or left side wall, or above the top compartment for vegetables.
If you have a model with a system No Frost or two compressors, the situation may be different. In such cases, there are often separate regulators for each camera or a remote control panel on the front of the housing. Some models are equipped with an internal ⚠️ Attention: Never try to forcefully tear off the plastic plugs or pick the regulator with sharp objects. At low temperatures, plastic becomes brittle and breaks easily, which will lead to the need to replace the part.thermostat, hidden under a plastic cover, access to which is limited.

To accurately determine the location, refer to the passport of your device. If the documentation is lost, carefully inspect the upper part of the refrigerator compartment - this is where the climate control mechanism is most often hidden.
Setting the mechanical thermostat
The mechanical regulator is a dial with digital designations from 1 to 7 (or from Min to Max). Many users mistakenly believe that the numbers represent degrees Celsius. In fact, these are conditional power modes cooling: the higher the number, the colder it will be in the chamber.
The optimal position for everyday work is considered to be 3 or 4. In this mode, the refrigerator maintains a temperature of about +4...+5°C, which is ideal for most products. If you set the knob to maximum (6 or 7), the compressor will work almost non-stop, trying to cool the chamber to the maximum values.
The adjustment should be carried out smoothly. Turning the knob suddenly from minimum to maximum will create a stressful situation for the coolant and the motor. Give the system time (about 30-40 minutes) to stabilize after each change in the position of the regulator before rechecking the temperature.
Adjusting the electronic control panel
Owners of models with electronics are luckier: there is no need to guess what the number “5” means. The display shows the actual or set temperature in degrees Celsius. To change parameters, arrow buttons or touch zones are usually used + and -.
The standard setting for the refrigerator compartment is +3°C or +4°C. For the freezer, the optimal value is -18°C. If you have loaded the chamber with a large amount of warm food, you can temporarily turn on the "Super Freeze" or Super Freezemode, which makes the compressor work harder.
| Value on the display | Mode work | Impact on products | Energy consumption |
|---|---|---|---|
| +1...+2°C | Intensive cooling | Risk of freezing of vegetables and fruits | High |
| +3...+5°C | Normal mode | Optimal storage | Medium |
| +6...+8°C | Economy mode | Reducing the shelf life of dairy products | Low |
| -18°C and below | Frozen | Long-term storage of meat | High |
Do not forget that electronics are sensitive to power surges. If the control panel behaves strangely (flashes, does not respond), try unplugging the refrigerator for 10-15 minutes to reboot the controller.
Setting features of two-compressor models
Refrigerators Atlant with two compressors allow you to adjust the temperature in each compartment independently of each other. This gives a huge advantage: you can turn off one of the chambers or set them to completely different modes.
Regulators in such models are usually located nearby or are color-coded (blue for refrigeration, red for freezer). When setting up, it is important to remember thermal insulation: if one chamber is empty and the second is filled with products, the load on the compressors will be distributed unevenly.
☑️ Checking the settings of a two-compressor system
If you rarely use the freezer, there is no point in keeping it at a minimum. Raise the temperature to -10...-12°C, which will significantly reduce energy consumption, but will allow you to store frozen foods without the risk of spoilage.
Typical errors and ways to eliminate them
The most common mistake is setting the regulator to maximum immediately after defrosting or loading warm products. Users think this will speed up cooling, but in reality it only overloads the system. The compressor will not be able to cool the chamber faster, it will simply work for wear.
Another problem is ignoring the position of the refrigerator. If the unit is too close to the wall or radiators, heat transfer is disrupted. In this case, no adjustment of the thermostat will help: the refrigerator will “think” that the chamber is warm and work continuously.
⚠️ Attention: If, after adjusting the temperature, the refrigerator continues to work without stopping for more than 24 hours, and a “fur coat” or ice forms inside, the problem may not be in the settings, but in a freon leak or a malfunction of the thermostat.
Also often forgotten about the tightness of doors. A loose seal allows warm air to pass through, causing the sensors to require more intense motor operation. Check the fit of the door with a simple sheet of paper: clamp it around the perimeter of the closed door - it should be pulled out with force.
Why does the thermostat click?
A characteristic click when the compressor turns off is normal. This opens the contacts of the mechanical thermostat. If the clicks are frequent and chaotic, the regulator may be faulty or the installation location of the refrigerator is incorrect (vibration).
Frequently asked questions (FAQ)
Which position of the thermostat knob is the most economical?
The most economical position is considered 2 or 3 (depending on the scale). However, if the chamber is warmer than +7°C, the food will begin to deteriorate, which will reduce the savings to nothing. The golden mean is 3.
Is it possible to completely turn off the thermostat?
The mechanical thermostat can be unscrewed to position 0 or Off, which will break the compressor power circuit. The electronic unit is turned off by the power button or by unplugging the plug from the socket.
Why do vegetables freeze at the back wall in the refrigerator compartment?
This is a sign of too low a temperature or a malfunction of the damper (in No Frost systems). Try reducing the cooling power by 1 notch and not placing food close to the back wall.
How often should you recheck the settings?
Seasonal. In winter, when the apartment is cooler, the load on the refrigerator is reduced and it may turn on less often. In the summer, when it’s hot, you may need to increase the cooling mode by 1 notch.
