Optimal temperature conditions are the key not only to the long-term preservation of products, but also to the proper operation of the unit itself. The owner of household appliances is often faced with the need to change settings after purchase, seasonal changes in the indoor climate, or when loading a large volume of products. Correct temperature control in a two-chamber Atlant refrigerator allows you to save energy and prevent spoilage of supplies.
Mechanical and electronic control systems require a different approach, but the basic physical principles of cold circulation remain unchanged. In this article, we will analyze the nuances of setting thermostats of various modifications, explain the meaning of the numbers on the scale and help you avoid common mistakes during operation.
Incorrectly set parameters can lead to the formation of a snow coat in the chamber or, conversely, to insufficient cooling. Understanding the operating principles of your two-chamber refrigerator will be the key to its long and trouble-free service.
The principle of operation of the thermostat in Atlant refrigerators
The main element of the temperature control system is thermostat (thermostat). It is he who gives the signal to the compressor to turn on when the temperature in the chamber rises above the set value, and turns it off when the required minimum is reached. In models with mechanical control, this process is controlled by a sensitive membrane that responds to the expansion or contraction of the refrigerant inside the capillary tube.
Electronic systems found in more modern lines use temperature sensors to monitor the state of the environment. They provide more accurate maintenance of specified parameters, minimizing fluctuations. Regardless of the type of control, the system has the same goal - to create a stable temperature regime in all compartments temperature regime in all departments.
⚠️ Attention: The thermostat is not intended for quick freezing of products. Its main function is to maintain the already achieved temperature, and not emergency cooling.
It is important for the user to understand that adjustment does not occur by supplying cold, but by changing the threshold values for turning the compressor on and off. When you turn the knob, you change the cut-off point, causing the motor to work longer or less.
How does the inertia of the system work?
The refrigerator is an inertial system. After turning the knob, the temperature does not change instantly, but over several hours of compressor operation. You should not turn the regulator every 15 minutes while waiting for the result.
Deciphering the temperature control scale
On the front panel of the refrigerator compartment there is a thermostat knob with digital symbols. Many users mistakenly believe that the numbers correspond to degrees Celsius, but these are only conventional divisions of cooling power. The standard scale usually varies from 1 to 7 (or from Min to Max).
The logic of the scale is the same for most models: the higher numberthe lower temperature inside the camera. Setting the knob to “7” or “Max” forces the compressor to work almost non-stop, trying to achieve the lowest possible values. On the contrary, position “1” or “Min” means that the unit will turn on rarely, maintaining a relatively warm mode.
For standard storage of products in the main chamber, the position of the regulator between 3 and 4. This ensures a balance between power consumption and cooling quality. Factory settings, as a rule, are already set in this range.
- ❄️ Number 1 - minimum cooling (about +8..+10°C).
- ❄️ Numbers 2-3 - mode for storing vegetables and fruits.
- ❄️ Numbers 4-5 - optimal mode for meat, dairy products and ready-made food.
- ❄️ Numbers 6-7 - intensive cooling or freezing mode.
Setting the mechanical thermostat
Mechanical models of Atlant refrigerators, such as the popular series 40, 42, 45, equipped with a classic rotary handle. Adjustment is carried out by rotating this handle clockwise to increase the cold and counterclockwise to weaken it. The setup process is simple, but requires following a sequence of actions to achieve a stable result.
First you need to free access to the regulator, which is usually located in the upper part of the refrigerator compartment, sometimes hidden by a decorative panel. It is not recommended to change the position of the handle with a sudden movement; it is better to do this smoothly, fixing each division.
☑️ Algorithm for setting the mechanics
After changing the position of the handle, the refrigerator needs time to stabilize the new mode. The compressor must run a full cycle so that the temperature throughout the volume is equalized. Only after this can you evaluate the result and, if necessary, make adjustments.
⚠️ Attention: Do not set the regulator to the maximum value (7 or Max) for continuous operation. This will lead to freezing of the evaporator, overload of the compressor and increased energy consumption.
If you notice that the food in the back of the chamber begins to freeze, and the regulator is set to “4” or “5”, try lowering the value to “3”. And vice versa, if the milk quickly sours, the value needs to be increased.
Temperature control in models with electronics
Modern two-chamber Atlant refrigerators, including series with the system No Frost or Full No Frost, are often equipped with an electronic control unit. The interface can be represented by LED indicators and touch buttons or a display on the door. The accuracy of the settings in such models is higher, and the functionality is expanded.
To change the parameters, you need to press the settings button (often indicated as Temp or the image of a thermometer). The display will flash the current temperature in the refrigerator compartment. Using the arrow buttons ▲ and ▼, the user sets the desired numerical value in degrees Celsius.
The difference from mechanics is that you set a specific target temperature, and not a conditional power. The electronics itself will calculate the operating time of the compressor. After confirmation with the button OK or Enter new parameters are saved in memory.
| Parameter | Mechanical control | Electronic control |
|---|---|---|
| Accuracy settings | Conditional (in divisions) | High (up to 1°C) |
| Indication | No or LEDs | Digital display |
| Super freezing mode | Separate button/toggle switch | Automatic timer |
| Surge protection | Basic | Advanced |
However, after switching on, it may take several hours to reach the set mode.
Features of adjustment depending on the season
The external ambient temperature directly affects the heat transfer of the refrigerator. In the summer, when the apartment is hot, it is more difficult for the unit to release heat through the condenser (the grille at the back). In winter, on the contrary, heat transfer improves. Therefore, seasonal adjustment of settings is not a myth, but a necessity for proper operation.
In summer, especially if the room temperature exceeds +25°C, it is recommended to install the regulator closer to the average values (3 or 4). An attempt to set the cold “minimum” (number 1) may lead to the fact that the compressor simply will not be able to reach the desired temperature and will work continuously, which can lead to overheating.
In winter, if the refrigerator is in a cool room (for example, on an insulated balcony or in a cold hallway), the situation changes. When the air temperature is below +16°C, the thermostat may “think” that the chamber is already cold enough and does not turn on the motor. In this case, it may be necessary to set the regulator to stronger cooling (numbers 4-5) to force the cycle to start.
Following seasonal recommendations allows you to extend the service life compressor and avoid the formation of condensation on the walls.
Using the “Super Freeze” function
For quick freezing of fresh food or creating a supply of ice, Atlant two-chamber refrigerators have the “Super Freeze” function. Activating this mode puts the compressor into continuous operation mode, ignoring the readings of the main chamber thermostat.
In mechanical models, a separate toggle switch or button, often located next to the thermostat or on the top panel, is used to turn it on. Switching on is accompanied by the yellow indicator lighting up. In electronic models, the mode is activated through the menu or a separate button Super.
It is critically important not to leave this mode on all the time. In mechanical refrigerators, shutdown occurs manually (the toggle switch returns to its original position) when the food is frozen. In electronic models, the timer usually turns off the function automatically after 24-72 hours.
⚠️ Attention: Long-term operation in super freezing mode (more than 3 days) can lead to breakdown of the thermostat and failure of the compressor due to overheating. Use the function only when necessary.
After freezing is completed, be sure to return the settings to normal mode to avoid excessive energy consumption and freezing of products in the main chamber.
Diagnostics of problems with temperature conditions
Sometimes even correct adjustment does not give the expected result. If you have set the average values, but the food spoils or, on the contrary, freezes, the problem may lie not in the settings, but in a malfunction of the equipment. There are a number of signs that indicate the need to call a technician.
One of the common problems is a refrigerant leak. In this case, the compressor runs constantly, trying to gain temperature, but there is no cold. Another option is sticking of the thermostat contacts, when the motor either does not turn on at all or never turns off.
It is also worth checking the tightness of the sealing rubber bands on the doors. If the rubber has dried out or become dirty, warm air constantly flows inside, knocking down the thermostat settings.
- 🔍 Freezing of the “fur coat” on only one wall indicates problems with defrosting.
- 🔍 An audible click and failure to start the motor indicate problems with the starting relay or thermostat.
- 🔍 Puddles of water under the refrigerator may indicate a clogged drainage hole.
Timely detection of anomalies in operation allows you to avoid costly repairs and loss of food.
Is it possible to regulate the temperature in the freezer separately?
In most Atlant two-chamber refrigerators with one compressor and mechanical control, there is no separate temperature control in the freezer compartment. It depends on the operation of the main thermostat and damper. In models with a system No Frost and electronic control, independent temperature settings for each compartment are often available.
Why does the temperature not restore for a long time after defrosting?
After complete defrosting and washing, the refrigerator takes 4 to 8 hours to return to operating mode. It is not recommended to load a large volume of products at this time, as this will increase the stabilization time. Make sure the door is tightly closed during this period.
What to do if the thermostat knob rotates?
If the knob rotates 360 degrees and does not lock, or, conversely, does not spin at all, this is a sign of a mechanical breakdown of the thermostat itself. Operation in this condition is impossible - the part must be replaced by a specialist.
Does the amount of food affect the temperature setting?
Yes, a full refrigerator keeps the cold better than an empty one, since food acts as cold accumulators. However, for normal air circulation, the chamber should not be packed tightly. Fill the volume no more than 70-80%.
How often should you check the temperature settings?
It is enough to check the readings with a thermometer once every six months or when the season changes (winter/summer). Monitoring is also necessary if you notice a change in the quality of food storage or a change in the sounds of the compressor.
