Correct adjustment of the climate inside refrigeration equipment is the foundation for long-term preservation of food freshness and energy efficiency of household appliances. Owners of Belarusian-made units are often faced with the need for fine calibration, since the factory settings may not correspond to specific operating conditions or seasonal changes in the room. Temperature control in the Atlant refrigerator depends on the model of the device, the type of control system installed, and even on the time of year outside.
Incorrectly set parameters lead to rapid spoilage of food, the appearance of an unpleasant odor, or, conversely, to freezing of vegetables and fruits, which lose their structure and taste. Understanding the principles of operation thermostat allows you to avoid unnecessary calls to the technician and extend the life of the compressor. In this article, we will analyze in detail the algorithms of action for various modifications of equipment, explain the physical principles of operation of sensors and help optimize the operating modes of your device.
Before you begin manipulating handles or touch panels, you must clearly determine what type of control is installed in your unit. The entire further adjustment strategy and the accuracy with which you can set the desired degrees depend on this. Errors at the initial stage can lead to the system working incorrectly, constantly turning on and off.
Types of temperature control in Atlant refrigerators
All models of refrigeration equipment can be divided into two large groups according to the way they interact with the user: mechanical and electronic. In old and budget series, such as classic two-chamber models, it is most often found mechanical thermostat. It is a round knob with digital divisions, usually located inside the refrigerator compartment on the top panel or on the side wall.
The operating principle of such a device is based on the expansion and compression of a special gas or liquid in a capillary tube, which responds to changes in heat. The numbers on a scale from 1 to 7 (or from Min to Max) do not indicate specific degrees Celsius, but only indicate the intensity of cooling. The higher the number, the colder it will be inside. In more modern models, especially in lines with a system No Frost or Frost Free, control is carried out through an electronic unit.
The electronic panel can be located on the outer door or be hidden, displaying data on a small display inside the camera. Here the adjustment is made with an accuracy of one degree, which is a significant advantage. The system itself controls the operation of the compressor and fans, relying on readings from built-in sensors. The user only sets the target value, and microprocessor does the rest of the work.
⚠️ Attention: In mechanical models, the thermostat knob cannot be turned with force through the extreme positions of the scale. This can lead to rupture of the capillary tube and failure of the entire thermoregulation system.
It is also important to note that in two-compressor models, temperature control in the refrigerator and freezer compartments occurs independently of each other. This gives greater flexibility in settings, allowing, for example, to freeze a large amount of food without affecting the storage mode of vegetables in the upper compartment.
Setting up a mechanical thermostat
If your refrigerator has a mechanical handle, the setup process requires a certain approach and understanding of the physics of the process. The controller usually has a scale from 1 to 7, where 1 is the minimum cooling (warmest) and 7 is the maximum cooling (coldest). Position “0” or “Off” means the compressor is completely turned off.
For everyday use, the optimal position of the knob is between 3 and 4. This ensures a balance between energy consumption and storage quality. However, if you have loaded the chamber with a large amount of warm food or the temperature in the kitchen has increased significantly, you may need to shift the regulator towards higher values.
- 🌡️ Position 1-2: Suitable for storing food that does not require strong cooling, or in winter when the room is cool.
- ❄️ Position 3-4: Standard mode for daily use with normal chamber load.
- 🧊 Position 5-7: Intensive cooling mode, used briefly for quick freezing or at high ambient temperatures.
It is worth remembering that changing the position of the handle does not give an instant result. Thermal stabilization of the system takes time. After turning the knob, it takes 4 to 6 hours for the temperature inside the chamber to level out and reach new values. Only after this can you evaluate the effectiveness of the setting and, if necessary, adjust it.
Particular attention should be paid to seasonality. In the summer, when the apartment is hot, a mechanical thermostat can work to the limit of its capabilities if the knob is turned to the minimum. In winter, on the contrary, the compressor may turn on rarely, and the food may thaw if the cooling intensity is not increased.
Adjusting electronic controls
Electronic control systems in refrigerators Atlant provide the user with much wider possibilities. The display shows the actual temperature in degrees Celsius, eliminating the need to guess what the "5" on a mechanical knob means. Typically, the control panel is equipped with "+" and "-" buttons or touch fields for changing values.
To change the temperature in the refrigerator compartment, you must press the corresponding chamber selection button (often indicated by a snowflake symbol for the freezer and a drop or thermometer for the refrigerator compartment). Once the setting mode is activated, the numbers on the display will begin to flash. Using the adjustment buttons, you set the desired value.
The standard recommended temperature for the refrigerator compartment is from +3°C to +5°C. In this mode, bacteria multiply slowest, and food does not freeze. In some models with a freshness zone (zero chamber), you can set individual parameters close to 0°C, but with high humidity.
| Mode | Temperature (°C) | Recommended products | Shelf life |
|---|---|---|---|
| Optimal | +3...+5 | Dairy products, ready meals, meat | Standard |
| Eco / Energy | +6...+7 | Fruits, vegetables, drinks | Medium |
| Intense | +1...+2 | Perishable foods, defrosting | Short-term |
| Freshness zone | 0 | Fresh meat, fish without freezing | Increased |
After setting the desired parameters, you need to confirm the selection, usually this happens automatically a few seconds after the last press, or you need to press the confirmation button. The electronics itself will distribute cold air throughout the system air ducts.
☑️ Checking the electronic settings
The influence of loading and placing products
Even a perfectly tuned refrigerator will not work effectively if the rules for its loading are violated. Circulating cool air is key to uniform cooling. In models with the system No Frost air is forced by a fan and passes through special channels, so it is important not to block the outlet openings.
If you tightly fill the chamber with products to the very top, blocking the shelves and back wall, cold air will not be able to get into the lower drawers. As a result, food in the upper part can freeze, and in the lower part it can spoil due to lack of cold. The optimal occupancy is about 70% of the total volume.
It is also important to take into account thermal inertia. Hot or even just warm dishes placed on a shelf sharply increase the overall temperature inside, forcing compressor to work hard. This leads to an increase in energy consumption and a reduction in the service life of equipment.
⚠️ Attention: Never place hot pots directly on the shelves. Allow food to cool to room temperature in the kitchen before storing it in the refrigerator.
Distribute food evenly across the entire shelf area. Don't leave large empty spaces on one side and a dense wall of food on the other. Air should freely flow around each bag and container.
Why can’t you store food in bags at the back wall?
The back wall in static refrigerators (drip type) is an evaporator. Its temperature can drop below zero even at a setting of +4°C. Products that come into contact with it freeze, lose moisture and spoil. Always leave a gap of 2-3 cm.
Seasonal characteristics and external factors
External ambient temperature has a direct impact on the operation of the refrigeration unit. In summer, when the kitchen is hot, heat exchange between the refrigerator body and the air in the room is difficult. The compressor has to work longer and more often to maintain the set internal mode.
In winter, the situation changes. If the refrigerator is located in an unheated room (for example, on a balcony or in a garage, which, by the way, is not recommended by manufacturers), the oil in the compressor may thicken and the refrigerant may stop circulating effectively. However, if the equipment is in a warm kitchen, it is easier for it to give off heat in winter, and it may work less often.
For mechanical thermostats, there is the concept of “ambient temperature compensation”. Some models are equipped with an additional Winter/Summer switch (usually inside the camera next to the handle). In winter, this switch activates an additional heating element so that the thermostat “thinks” that the chamber is warmer and turns on the compressor to operate the freezer.
- ☀️ In summer: Increase the cooling intensity (move the knob closer to maximum or lower the degrees on the electronics) if the room is stuffy.
- ❄️ In winter: When using mechanics in a cool room, you may need to turn on the "Winter" mode or shift the knob to lower values.
- 🏠 Location: Do not place the refrigerator close to the wall or next to the radiator/stove. This disrupts the heat dissipation and disrupts the temperature settings.
If you notice that with the normal setting, the refrigerator begins to work continuously or, conversely, almost does not turn on, check whether its operating conditions have changed. Perhaps summer has arrived and it has become hotter, or you have moved the equipment to a warmer place.
Diagnostics of problems with temperature conditions
Sometimes users turn the controls endlessly, trying to achieve the desired effect, although the problem lies not in the settings, but in a malfunction. How to understand that equipment requires repair, and not just calibration? The first sign is a discrepancy between the actual temperature and the set one.
If the electronic display shows +4°C, but the milk has frozen into ice, or vice versa - the food is warm, but the compressor is silent, this is a signal of a failure. In mechanical models, problems are indicated by the freezing of a “coat” of ice on the back wall (in drip models) or the lack of periodic thawing.
Frequent switching on and off of the compressor (short cycle) also indicates a problem with thermoregulation. The sensor can “lie”, telling the control unit that the temperature has already been reached, although this is not the case, or vice versa.
It is also worth checking the integrity of the sealing rubber bands on the doors. If the rubber is dry or torn, cold air will evaporate and warm air will flow inside. In this case, no adjustment of the thermostat will help - the refrigerator will work for wear and tear, trying to compensate for heat inflows.
Why does ice freeze on the back wall in the Atlant refrigeration chamber?
In models with a drip defrosting system, the formation of ice on the back wall during compressor operation is a normal physical process. Moisture from the air condenses and freezes. The problem occurs if the ice does not drain into the drain hole after the compressor is turned off. This may be due to the set temperature being too low (knob at 6-7), clogged drainage or the door not closing tightly.
Is it possible to store a refrigerator at sub-zero temperatures?
Manufacturers categorically do not recommend operating household refrigerators at ambient temperatures below +10°C (and for some models below +16°C). At low temperatures, the oil thickens, the thermostat stops working correctly and the plastic housing may be damaged. If the refrigerator must operate in an unheated room, you need a special model with climate class SN-T or ST.
How often do you need to defrost the Atlant refrigerator?
The frequency of defrosting depends on the system. Models with No Frost (no frost) do not need to be defrosted in the refrigerator compartment at all; it is enough to wash the shelves as they become dirty. It is recommended to defrost the freezer compartment in No Frost systems once a year for hygiene. Models with a drip system (crying wall) require defrosting only if the ice thickness exceeds 5-7 mm, usually 1-2 times a year.
What to do if the Atlant refrigerator makes a lot of noise after setting it up?
If you have increased the cooling power (set the minimum degrees), the compressor will work more intensely and, accordingly, noisier. This is fine. However, if there is a knocking, vibration or humming that was not there before, check whether the refrigerator is level (adjusting the legs), whether the pipes are touching the back wall of the wall, and whether the chamber is overloaded with products that create resonance.
