Correctly setting the temperature in the refrigerator compartment is the foundation for long-term storage of products and preserving their taste. Owners of household appliances Atlant often face the need to change standard factory settings after purchase or due to seasonal changes. An incorrect temperature balance can lead to rapid spoilage of food or, conversely, to its freezing and loss of beneficial properties.
Modern models of the Belarusian manufacturer are equipped with both mechanical and electronic control systems, each of which has its own calibration features. Understanding the principles of operation thermostat allows the user to independently optimize the operation of the unit without calling a technician. In this article, we will analyze in detail the algorithms of action for various series of equipment.
Before you start setting up, it is important to make sure that the equipment is installed level and the doors fit snugly to the body. Any manipulations with the regulators should be carried out smoothly, avoiding sudden movements, so as not to damage the sensitive mechanisms. Let's look at exactly how the process of setting the required values occurs.
Principles of operation of the Atlant cooling system
Refrigerators Atlant work on the principle of a compression cycle, where the refrigerant circulates in a closed circuit, taking heat from the internal chamber. This process is controlled through thermostat or an electronic module that reads temperature sensors. In mechanical models, the user directly influences the tension of the thermostat spring, changing the compressor switching point.
Electronic systems provide more precise control, allowing you to set the temperature in steps of one degree. Here the signal from the sensor is transmitted to controller, which makes the decision to start or stop the engine. Such a system minimizes temperature fluctuations and creates more stable conditions for storage.
⚠️ Attention: A sharp change in the thermostat settings (more than 2-3 steps at a time) can lead to increased load on the compressor and a reduction in its service life. Make adjustments smoothly.
It is important to understand the difference between the air temperature in the chamber and the temperature of the products. The air cools faster, but it is the thermal inertia of the products that determines the frequency at which the compressor is turned on. Therefore, after changing the settings, you need to wait several hours to stabilize the processes.
Setting a mechanical thermostat
In classic refrigerator models Atlant adjustment is carried out using a rotary knob, usually located inside the chamber or on the front panel. The scale of such a regulator does not directly display degrees Celsius, but represents conventional units from 1 to 7 (or from Min to Max). A simple rule applies here: the higher the number, the lower the temperature inside the chamber.
To set the optimal mode, it is recommended to turn the knob to the position corresponding to the middle of the scale (usually the number 3 or 4). This value is the factory standard for most operating conditions. If the room is hot, you can increase the cooling power by moving the regulator towards higher values.
However, it is worth considering that mechanical thermostats have a certain error. The position of the handle only sets the approximate range in which the equipment will work. The exact value depends on the chamber load, the frequency of door opening and the ambient temperature in the kitchen.
If you notice that the food in the back of the chamber begins to freeze and ice forms on the walls, you should reduce the power by turning the knob towards lower values. And vice versa, if the milk quickly sours and the meat loses color, you need to add “degrees” by moving the regulator to the right.
Temperature adjustment in models with electronic control
Modern series Atlant with the No Frost system and an electronic control unit allow you to set the temperature with high accuracy. The control panel may be located on the outside of the door or hidden behind it, depending on the model. The digital display displays the current values, and the “+” and “-” buttons allow you to change them step by step.
To enter the setup mode, you often need to briefly press or hold a certain key, indicated by a thermometer symbol. After activating the mode, the refrigerator or freezer indicator will start flashing. Using the navigation buttons, set the required value, for example +4°C for the main chamber.
- 🌡️ Press the chamber selection button to switch between the refrigerator and freezer compartment.
- ➕ Use the "Plus" button to increase cooling capacity (lower temperature).
- ➖ Use the "Minus" button to reduce cooling (increase the temperature).
The electronics also allow you to activate special modes such as “Super Freeze” or “Vacation”. The “Super Freeze” mode forcibly keeps the compressor on for a long time, which is useful when loading a large amount of fresh food. However, it is not recommended to use it constantly, as this leads to excessive consumption of electricity.
☑️ Checking the electronics settings
Optimal temperature conditions for different products
There is no universal temperature ideal for all products. Different groups of products require different storage conditions to maximize freshness. In refrigerators Atlant with several cooling zones or special shelves, you can create the desired microclimate.
Meat and fish products require the lowest temperatures, close to zero, but without freezing. It is better to store dairy products and ready-made meals at standard +2...+4°C. Vegetables and fruits, on the contrary, are sensitive to cold and may lose taste or turn black if the values are too low.
| Product type | Recommended temperature | Shelf life (approximate) |
|---|---|---|
| Fresh meat, fish | 0°C... +2°C | 1-3 days |
| Dairy products | +2°C... +4°C | 3-7 days |
| Vegetables, fruits | +4°C... +8°C | 5-14 days |
| Ready meals | +2°C... +5°C | 1-2 days |
In models with the “Freshness” zone (zero zone), the temperature is automatically maintained close to 0°C, which is ideal for meat and fish. If your model does not have such a zone, try to place perishable products on the bottom shelf, closer to the back wall, where it is coldest.
The influence of external factors on the operation of the refrigerator
Setting degrees on the refrigerator Atlant does not occur in a vacuum. The operation of the unit is directly affected by the temperature in the room where it is installed. In the summer, when the apartment is hot, heat exchange is difficult, and the compressor has to work harder to maintain the set parameters.
In winter the situation may be the opposite. If the refrigerator is placed on an unheated loggia or in a cold corridor, the oil in the compressor may thicken and the refrigerant may not circulate as well. In such conditions, a mechanical thermostat may simply not turn on the compressor, as it will seem to it that it is already cold enough inside.
⚠️ Attention: Operating the refrigerator at ambient temperatures below +10°C or above +32°C is not recommended by the manufacturer. This can lead to compressor failure or incorrect operation of the automation.
It is also important to consider the loading density of the chamber. An empty refrigerator cools down faster, but also heats up faster when the door is opened. A full chamber holds the cold better (products work as cold accumulators), but requires more time for initial cooling and proper air circulation.
Frequent opening of the door makes its own adjustments. If there are a lot of people in the house or there are small children who often look inside, it makes sense to set the temperature 1 degree lower than standard to compensate for the constant flow of warm air.
Diagnosing and eliminating temperature problems
Sometimes users are faced with a situation where the seemingly correct setting does not produce results. Products spoil or, conversely, freeze even at average regulator values. First of all, you should check the tightness of the door. If the rubber band is worn out or dirty, the cold will escape and the compressor will work non-stop. seal doors. If the rubber band is worn out or dirty, the cold will escape and the compressor will work non-stop.
Another common reason is improper defrosting. If in refrigerators with a drip system or No Frost an ice “coat” has formed on the evaporator, heat exchange is disrupted. In this case, adjusting the thermostat will not help - complete defrosting of the unit is required within 10-12 hours.
What to do if the compressor is humming, but there is no cold?
If the motor runs constantly, but the temperature does not drop, there may be a freon leak or a blockage in the capillary tube. The thermostat itself could also be faulty. In such cases, you need to call a technician to diagnose and refill the refrigerant.
It is also worth checking the location of the products. If you cover the vents at the back of the chamber with boxes or bags, cold air will not be able to circulate. The temperature sensor will read the local heat and command increased cooling, which will lead to freezing of other zones.
If after all the checks and correct settings the problem persists, the temperature sensor itself or the electronic control module may be faulty. In such cases, independent repair is difficult and requires special equipment for diagnostics.
Frequently asked questions (FAQ)
Why does ice freeze in the Atlant refrigerator, although the thermostat is at a minimum?
This may indicate a leak in the door, a malfunction of the defrost heating element (in No Frost models) or defrost sensor failure. Also check whether the temperature is set too low in the freezer compartment, which may cause the opposite effect in the refrigerator compartment.
Which temperature should be set in summer and which in winter?
In summer, when it is hot, it is recommended to set lower values (closer to +3°C in the main compartment) to compensate for the heating. In winter, if the room is cool, you can slightly increase the temperature (up to +5°C) to reduce the load on the compressor, but not below the permissible standards for the products.
What does the flashing temperature indicator on the display mean?
A flashing indicator usually signals an alarm. This may be an increase in temperature above normal after defrosting or loading warm food, or a system malfunction. If the blinking does not stop after several hours of operation, contact service.
Is it possible to store the refrigerator at sub-zero temperatures?
It is strictly not recommended. The oil in the compressor thickens, and starting the engine can cause it to seize. Additionally, the plastic becomes brittle and electronics may not function properly. The minimum operating temperature is usually +10°C.
How often do you need to defrost the Atlant refrigerator?
Models with the No Frost system do not require manual defrosting; it is enough to wash them 1-2 times a year. Models with a drip system (“crying wall”) need to be defrosted completely 1-2 times a year for hygienic cleaning and prevention.
