Correct setting of climate control equipment is the key to the safety of products and the durability of the equipment itself unit. Many equipment owners are faced with a misunderstanding of exactly how the thermostat functions, which leads to food spoilage or the formation of ice. In refrigerators Atlant temperature control is implemented in several ways, depending on the model and year of manufacture.
In this article we will analyze in detail the mechanical and electronic control systems, explain the meaning of the division scale and help you choose the optimal mode for your kitchen. Understanding the operating principles of compressor and sensors will allow you to avoid common operating mistakes.
Before moving on to specific numbers and knobs, it is important to understand the basic principle of operation of the refrigeration circuit. The temperature inside the chambers is not set directly in degrees Celsius on most mechanical models, but is regulated by the current supplied to the motor.
Principles of operation of the thermostat in Atlant refrigerators
The main element responsible for cold is the thermostat. In classic models, this is a mechanical device that opens and closes the electrical circuit depending on the temperature of the evaporator. The user, by turning the knob, changes the tension of the spring inside the sensor, which shifts the response threshold.
The higher the number on the scale, the more the spring is compressed, and the lower the temperature inside the chamber must drop for the circuit to open and the compressor to turn off. Consequently, setting the regulator to maximum forces unit to work almost non-stop, reaching the lowest possible temperatures.
Modern models with a system No Frost or electronic control use digital sensors that transmit data to the control board. Here the process looks different: you set the desired temperature, and microprocessor decides when to turn on the motor-compressor. This provides a more stable climate and energy savings.
⚠️ Attention: If you have just installed a new refrigerator or defrosted it, do not immediately try to set the maximum cold. Let the equipment operate in standard mode for 5-6 hours to stabilize the processes.
It is important to understand that even with the correct settings, the temperature at different points in the chamber may differ. This is a physical feature of air circulation. Cold air is heavier than warm air, so it sinks down, and warm air rises.
Deciphering the temperature regulator scale
The numerical scale on mechanical thermostats raises the most questions. Unlike electronic panels, there is no degree display. The range usually varies from 1 to 5 or from 1 to 7, sometimes there are markings Min and Max.
The logic is simple: the number “1” corresponds to the minimum cooling power (the highest temperature in the chamber, about +5...+7°C), and the last digit of the scale corresponds to the maximum (the temperature can drop to 0°C and below). Zero or position Off means complete shutdown of the compressor.
The golden mean for everyday use is considered to be the position of the handle between 2 and 3 (on a scale up to 5) or 3 (on a scale up to 7). This ensures a balance between food safety and engine load. Setting the regulator to maximum is permissible only in two cases: when starting up an empty refrigerator for the first time or when quickly freezing a large volume of food.
If you notice that a “coat” of ice is constantly growing on the back wall of the main chamber, and the food in it is freezing, it means that the regulator is turned up too much. In this case, you need to turn the knob towards lower values. Conversely, if the chamber is warm and the food spoils quickly, it is necessary to increase the cooling power.
Optimal temperature conditions for different compartments
In order for the food to remain fresh for as long as possible, it is necessary to maintain certain temperature conditions in different zones of the refrigerator. In the main camera, the ideal range is from +2 to +5 degrees Celsius. It is at these indicators that the growth of bacteria slows down, but the structure of the products is not disturbed.
In the freezer, the temperature should not be higher than -18°C. With this mode, most products can be stored for up to a year without loss of taste. If you plan to store supplies longer, it makes sense to set the mode super freezing, which briefly lowers the temperature to -24°C.
Fresh vegetables and fruits are best stored in special freshness zones or lower drawers, where the temperature is kept around +4...+6°C. Dairy products and meat require stricter refrigeration, so it is better to place them on the middle and lower shelves, closer to the back wall, but not close to it.
| Product type | Recommended temperature | Shelf life (approximate) | Zone placement |
|---|---|---|---|
| Meat, poultry (chilled) | 0...+2°C | 1-3 days | Bottom shelf |
| Dairy products | +2...+4°C | 3-7 days | Average shelf |
| Vegetables and fruits | +4...+8°C | 3-10 days | Bottom drawers |
| Ready meals | +2...+5°C | 1-2 days | Upper shelf |
It is worth considering that the temperature inside the chamber may rise briefly if the door is opened frequently. Therefore, try not to keep the door open longer than necessary. The operating mode is also affected by the ambient temperature in the room.
Setting up the electronic control and display
In models Atlant with electronic control (XM-4425, XM-6025 series and others), the setup is done through the panel on the door or inside cameras. Here you see the exact numbers, which makes the task much easier. The standard factory setting is usually +4°C for the refrigerator compartment and -18°C for the freezer compartment.
To change the parameters, you must press the temperature adjustment button for the corresponding compartment. Typically, holding the button for 3 seconds puts the system into setup mode, which is indicated by a blinking indicator. Using the arrow buttons or pressing again you can change the value.
Electronics allows you to activate additional functions such as "Vacation" or "Super Freeze". Mode Holiday (Vacation) raises the temperature in the refrigerator compartment to +10...+15°C, preventing the appearance of mold and odor while you are away, but saves energy. At the same time, the cold remains in the freezer.
☑️ Setting up an electronic refrigerator
If the alarm indicator lights up on the display (a frequently flashing red triangle or exclamation mark), this means that the temperature in the chamber is higher than normal. After setting the correct mode and closing the door, the indicator should go out after a while when the temperature stabilizes.
⚠️ Attention: The characteristics and interfaces of the control panels may vary depending on the specific modification of the refrigerator. Always check the instructions supplied with your device, as the sequence of buttons may differ.
The influence of external factors on temperature
Setting the thermostat is not a one-time procedure. The refrigerator Atlant, like any other equipment, reacts to changes in the external environment. In summer, when the apartment is hot, the compressor takes more time and effort to cool the chambers. In winter, in a heated room, the load is less.
The location of the refrigerator also plays a role. If it is placed close to a wall, near heating radiators, or in direct sunlight, cooling efficiency decreases. In such cases, even the maximum setting of the thermostat may not give the desired result, and the motor will operate in emergency mode.
The load of the chambers with products also affects thermodynamics. A full refrigerator holds cold better, since the products themselves are cold accumulators. An empty refrigerator heats up faster when the door is opened, which forces the automation or mechanics to turn on the compressor more often.
Why does the refrigerator not turn off?
If your refrigerator operates continuously, check the tightness of the door seals. Even a small gap leads to a constant flow of warm air, and the thermostat does not give the command to stop the motor. Also, the cause may be clogging of the ventilation ducts in No Frost systems.
It is important to regularly check the condition of the sealing rubber bands. If they are dirty or damaged, the seal is compromised. Wipe them with a soft cloth and soapy water. If the rubber has lost its elasticity and does not fit tightly, it must be replaced.
Typical mistakes when adjusting the cold
One of the most common mistakes is setting the regulator to maximum immediately after purchase. This places extreme stress on the new parts. It is better to let the equipment work in normal mode so that the refrigerant is evenly distributed throughout the system.
Another mistake is frequent and sudden changes in settings. Don't turn the thermostat knob back and forth expecting instant results. The refrigeration system takes time (from 2 to 24 hours) to stabilize the temperature after changing the settings.
Ignoring defrost in models with manual defrost also leads to a problem. A thick layer of ice on the evaporator acts as a heat insulator, preventing the food from cooling. As a result, the thermostat “thinks” that there is not enough cold and does not turn off the compressor, although the temperature in the chamber is already below zero.
Do not forget that the location of the products affects the sensors. If you put a bag of food directly on the temperature sensor (if it is visible) or blocked the air circulation channels in No Frost, the readings will be incorrect and the operating mode will be disrupted.
Diagnostics of problems with temperature conditions
If you set up the refrigerator according to the instructions, but the result does not meet expectations, perhaps the problem is not settings, but in a malfunction. The first sign of problems is often the inability to reach the set temperature, even with the compressor running non-stop.
In models with one compressor and two chambers, a violation of the temperature regime in one of them may indicate problems with the air flow switch or a refrigerant leak. If the freezer is cold normally, but the refrigerator is warm (or vice versa), this is a clear symptom of a malfunction.
You can check the accuracy of the thermostat readings using a regular household thermometer. Place a glass of water on the middle shelf, wait a few hours and measure the temperature. If the readings deviate greatly from the settings (by more than 2-3 degrees), calibration or replacement of the thermostat may be required.
Why does ice freeze in the Atlant refrigerator even with the correct settings?
Ice formation can be caused by several reasons: a loose door, a clogged drain hole through which condensate escapes, or a system malfunction defrosting (heating element or timer) in No Frost models. Ice may also appear if you put open liquid or hot foods into the chamber.
How often do you need to change the thermostat settings?
Under ideal conditions, the settings change seasonally (2 times a year). In winter, when the apartment is cooler, the power can be reduced slightly. In the summer, in the heat, add. If a stable temperature is maintained in the room all year round (+20...+22°C), then there is no need to change the settings.
What to do if the thermostat knob rotates?
If the knob rotates endlessly and does not lock in position, or, conversely, is jammed, this is a sign of a breakdown of the thermostat itself. In this case, temperature adjustment is impossible; a technician must be called to replace the part. Repairing this unit yourself without skills is dangerous.
Does the amount of food affect the temperature setting?
Yes, it does. An empty refrigerator loses cold faster when opened. If you store a small amount of food, you can set the regulator to a slightly lower power. A full load requires more intensive initial cooling, but then holds the temperature better.
