Correct set temperature in the Atlant refrigerator is a key factor that determines not only the shelf life of products, but also the energy efficiency of the entire device. Owners of two-chamber models often face a dilemma: how to set the thermostat so that vegetables do not freeze in the main chamber, and meat retains its properties in the freezer for months. Incorrect calibration leads to accelerated deterioration of stocks or, conversely, to unnecessary energy consumption.
Belarusian plant engineers Atlant design their equipment taking into account the climatic characteristics of the region, but the basic physical principles of storage remain unchanged for all modern refrigeration units. Understanding how cold air is distributed inside the cabinet will help you properly arrange food and extend the life of the compressor.
In this article we will analyze the technical nuances of the operation of thermostats and electronic control units, characteristic of different series of two-chamber units. You will learn why the indicators on the shelves at the back wall and at the door may differ, and how to avoid this with proper operation.
Standard temperature conditions for storage zones
In two-chamber models Atlant the climate inside is divided into several conditional zones, each of which is intended for certain categories of products. The main camera, where the mode is usually maintained from +2 to +5 degrees Celsius, is the most visited. This is where it is important to observe temperature gradient, since cold air is heavier than warm air and sinks down, although in models with the NoFrost or Fresh system the distribution can be more uniform thanks to fans.
The upper shelves are traditionally considered a zone for prepared foods, dairy products and drinks that do not require extreme refrigeration. The lower shelves, located above the vegetable drawers, are the coldest in the main compartment (not counting the freshness zone, if it is separate). This is where you should place raw meat, fish or semi-finished products that are planned to be cooked in the next 24 hours.
The refrigerator door is the warmest zone, subject to constant temperature changes when opened. It is strictly not recommended to place perishable products that require stable cold here. However, this is where it is convenient to store sauces, juices in original packaging and other goods with a long shelf life.
⚠️ Attention: In models with a drip defrosting system, an ice crust may form at the back wall. This is normal, but if the layer of snow exceeds 5 mm, check the tightness of the door and the operation of the seal.
The freezer in two-chamber Atlantakh usually provides a temperature of -18 to -24 degrees. This mode allows you to store food for up to a year without losing its nutritional value. It is important to understand what freezing temperature affects the cell structure of the product: the faster and deeper the freezing, the better the taste is preserved after defrosting.
Setting up a mechanical thermostat
Most classic models Atlant equipped with a mechanical regulator, which is a rotary knob with numbers from 1 to 7 (or from Min to Max). Many users mistakenly believe that the number on the scale corresponds to degrees Celsius, but these are only symbols of cooling power. The higher the number, the more intensively the compressor works and the lower the temperature inside the chambers.
For normal operation in the summer, when the ambient temperature in the kitchen is high, it is recommended to set the regulator to the middle position (usually 3 or 4). In winter, if the refrigerator is in an unheated room (although this is not recommended for most climate classes), the load can be reduced. Overloading the motor in the heat when setting the maximum value can lead to premature wear.
The setting process takes time to stabilize. After each turn of the knob, you must wait several hours before taking measurements or evaluating the result. Sudden mode switches create stress for the refrigerant and compressor.
If you notice that the food in the main chamber begins to freeze, and in the freezer, on the contrary, melts, the thermostat may have failed or the refrigerant needs to be replaced. In such cases, simply turning the knob will not help solve the problem.
Control of the electronic unit and display
Modern series Atlant, especially those belonging to the premium segment or equipped with the NoFrost system, are often equipped with electronic control. Here, settings are made through a keypad and digital display located on the outside of the door or inside the chamber. This interface allows you to set exact temperature in steps of 1 degree, which is impossible to do manually.
To enter the setting mode, you usually need to press and hold the temperature adjustment button for 3-5 seconds until the indicators start flashing. After this, short presses select the desired value. Some models allow you to independently regulate the climate in the refrigerator and freezer compartments, which is a big advantage when loading a large volume of food.
Electronics can also signal malfunctions. For example, a flashing light or beep often indicates that the internal temperature has exceeded an acceptable threshold. This can happen after defrosting, prolonged opening of the door or if the sensor breaks down.
| Mode | Temperature (HC) | Temperature (MK) | Purpose |
|---|---|---|---|
| Standard | +4°C | -18°C | Daily storage |
| Super freezing | +4°C | -24°C | Quick freezing of fresh food |
| Vacation | +15°C | -18°C | Energy saving, freezer is working |
| Cooling | +2°C | -18°C | Intensive cooling of drinks |
If the lights flicker frequently in your area, it is recommended to use a stabilizer or at least a surge protector to avoid resetting or burning the board.
Seasonal adjustments and climate influences
The ambient temperature directly affects the operation of the refrigeration circuit. In the summer, when the kitchen is hot, heat transfer from the condenser (the black radiator at the back) is difficult. In such conditions compressor he is forced to work longer and more often in order to maintain the specified parameters inside. If during this period you turn the regulator to the maximum, the motor can work without stopping, which can lead to overheating.
In winter, the situation is the opposite. If the refrigerator is in a cool kitchen (for example, +16..+18°C), it requires less effort to cool. However, for the correct operation of the freezer and condensate removal system in drip models, a minimum load is also necessary. Some older models may not start if the room is too cold, since the sensor does not see the need to turn on.
In the off-season, when the heating is not yet (or no longer) working effectively, the settings can be slightly adjusted to reduce power, saving energy. The main thing is to ensure that the temperature in the main chamber does not rise above +6 degrees, since this is already an area of active reproduction of bacteria.
⚠️ Attention: Do not install the refrigerator near heating radiators, stoves or in direct sunlight. Heating the outer wall causes the equipment to wear out, regardless of the settings.
Air humidity also plays a role. In very humid climates, condensation may form on the outer walls and seals, which is sometimes mistaken for a cooling system problem. Regular ventilation of the kitchen helps normalize the operation of equipment.
What is climate class?
Climate class (SN, N, ST, T) indicates the range of air temperatures in the room at which the refrigerator is guaranteed to operate correctly. For Russia, N (normal) and SN (subnormal) are most often suitable.
Features of storage of various products
Different groups of products require an individual approach to the temperature regime. Meat and fish are the most demanding: for their long-term storage in the main chamber (if not in the freezer) they need a temperature closer to 0..+2 degrees. For this purpose, some models Atlant provide a special zero zone or freshness zone.
Vegetables and fruits, on the contrary, do not like extreme cold. At temperatures below +4 degrees, many of them (especially cucumbers, tomatoes, greens) lose their taste, become watery or begin to rot. That is why they should be placed in special sealed boxes at the bottom of the refrigerator, where temperature changes are minimal.
- 🥛 Dairy products: require stable +2..+4°C, it is better to store on the middle shelf, not in the door.
- 🥩 Raw meat: optimally +0..+2°C, stored no more than 2 days, preferably in a vacuum.
- 🍺 Drinks: withstand a wide range from +3 to +10°C, can be placed in the door.
- 🥚 Eggs: sensitive to changes, it is better to keep them in the main chamber in a closed package.
Ready meals, soups and Salads should be cooled to room temperature before refrigerating. A hot pan will create local overheating, causing the sensors to give false commands to the compressor, and will also increase the risk of ice forming on neighboring products.
☑️ Checking the correct storage
Diagnostics of problems with temperature conditions
If you notice that the food deteriorate faster than usual or, conversely, freeze in the main chamber, it is necessary to carry out diagnostics. The first step should always be to check the door seal. Often the problem lies not in the settings, but in a dirty or damaged sealseal through which the cold escapes.
Another common reason is incorrect layout. If food is packed too tightly and blocks the vents (on air-circulating models), the cold may not be distributed evenly. As a result, an ice lump forms at the back wall, and there is heat at the door.
In models with mechanical controls, over time the thermostat itself may lose calibration. The spring weakens, and the numbers on the handle no longer correspond to the real state of affairs. In this case, only calling a technician to replace the part or experimental adjustment “by eye” with thermometer control helps.
⚠️ Attention: If the compressor operates continuously for more than 24 hours, and the temperature does not drop to the set temperature, or if the motor does not turn on at all, and there is heat in the chamber, these are signs of a serious malfunction (freon leakage, compressor failure). Professional repairs are required.
It is also worth checking whether the melt water drainage channel is clogged. If the water does not leave, it freezes, forming an ice plug that disrupts heat transfer and can lead to the evaporator “blowing out.”
Quick freezing modes and their influence
The “Super Freeze” function allows you to temporarily lower the temperature in the freezer to -24..-26 degrees. This is necessary when you load a large amount of fresh, not yet frozen food. Rapid freezing prevents the formation of large ice crystals inside the cells of meat or berries, preserving their structure and taste after defrosting.
In mechanical models Atlant this mode is often implemented by forcing the compressor to bypass the thermostat. The user must turn on the button or toggle switch himself and, what is critically important, do not forget to turn it off after a few hours (24 hours are usually recommended, but no more than 3 days in a row). Long-term operation in this mode leads to freezing of the evaporator and overload of the engine.
In electronic models, the shutdown timer is often built in automatically: after a specified period of time (for example, 24 or 48 hours), the system itself will return to standard settings. This eliminates the human factor and protects the equipment from working at its limit.
There is no point in using this mode for already frozen products - it is just a waste of electricity. Also, you should not turn it on “just in case” during normal loading with stores.
Is it possible to set the temperature below -24 degrees in the freezer?
Technically, some models allow you to lower the temperature to -26 or even -30 degrees in super-freeze mode, but it is not advisable to constantly maintain this mode. This increases energy consumption by 20-30%, and the quality of food storage at -18°C and -26°C for household needs is practically the same. Deep cold is justified only for short-term shock freezing.
Why does ice freeze in the Atlant refrigerator if you set it to maximum?
When the thermostat is set to maximum cooling (number 7 or Max), the compressor works almost without stopping. The moisture contained in the food and air actively evaporates and, when it hits the cold walls or evaporator, instantly crystallizes. In drip systems, water does not have time to flow into the drainage and freezes, forming a “fur coat.”
How often do you need to defrost the Atlant refrigerator?
Models with the NoFrost system do not require manual defrosting; it is enough to wash them 1-2 times a year. Classic drip refrigerators Atlant it is recommended to defrost completely (with unplugging for 10-14 hours) at least once every 6-8 months, or when the layer of ice on the back wall becomes noticeable (more than 3-5 mm).
Does the fullness of the refrigerator affect temperature?
Yes, it does. An empty refrigerator loses cold faster when the door is opened, as air circulates freely. A refrigerator that is filled (about 2/3) works more stable: food accumulates cold and maintains its temperature longer. However, you cannot overcrowd the chamber - air must circulate freely between the products for uniform cooling.
What to do if after defrosting the temperature does not return for a long time?
After complete defrosting, the refrigerator may take from 2 to 6 hours to reach operating mode. At this time, do not load products, let the equipment run idle. If the temperature has not stabilized after 8-10 hours, check if the super freeze mode is on and make sure the door is closed tightly. If the problem persists for more than a day, a technician needs to diagnose it.
