Owners of household appliances Atlant often face a dilemma when, after purchasing or defrosting, it is necessary to correctly set the thermostat settings. The control panel usually has a rotary knob with a digital designation, the range of which may vary depending on the specific model of the unit. Incorrect setting of the value can lead to food spoilage, excessive energy consumption, or even compressor failure due to operation in extreme mode.
Understanding the principle of operation of a mechanical thermostat is the key to the long service life of your device. The numbers on the regulator do not indicate degrees Celsiusand represent conventional units of cooling power. The higher the value you set, the more intensely the motor-compressor works, trying to achieve a lower temperature inside the chambers. For most models, the optimal mode is considered to be the middle position, however, there are nuances depending on the season and the load of the shelves.
In this material we will analyze in detail how to find the “golden mean” for your Atlant refrigeratorto ensure ideal storage conditions and minimize the load on the nodes unit. We will consider the influence of external factors, decipher the symbols on the scale and answer frequently asked questions from users.
The principle of operation of a mechanical thermostat
The mechanical thermostat installed in most models Atlantis a simple, but reliable device. Inside the housing there is a bellows tube filled with refrigerant, which reacts to changes in temperature. When you turn the knob, you mechanically change the tension of the spring, setting the contact threshold.
It is important to understand the logic of the scale: one means minimum cooling, and the maximum number (usually 5, 6 or 7) is the “Super Freeze” mode. In position “1” the compressor turns on rarely and operates for a short time, maintaining a temperature of about +5...+7°C. In the maximum position, the unit will work almost non-stop, lowering the temperature to -18°C and below, which is not required in normal food storage mode.
You shouldn’t think that setting the knob to maximum will make the food fresher. Excessive freezing can spoil the structure of vegetables, lead to cracking of glass and plastic containers, and also cause the formation of excess ice on the evaporator, which will require frequent defrosting.
Optimal values for different seasons
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 transfer heat through the condenser located at the rear. In winter, on the contrary, natural cooling of the room facilitates the operation of equipment. Based on this, seasonal adjustment is a prerequisite for proper operation.
In the summer, when the room temperature exceeds +25°C, it is recommended to set the regulator to the values 2 or 3. This will allow you to compensate for the high thermal load without switching the compressor to constant operation. If you set the knob to maximum in the summer, the refrigerator may simply not turn off, trying to reach the set low temperature, which will lead to overheating of the motor.
In winter, the situation changes. When the room temperature is around +18°C or lower, heat transfer occurs more efficiently. During this period, you can safely switch the regulator to 4 or 5. This will ensure deeper freezing and longer pauses in compressor operation, which saves equipment life. However, if you have central heating in your apartment and the temperature is consistently high, return to the average values.
Deciphering the digital scale on Atlant models
Different series of refrigerators Atlant may have different gradations of the thermostat scale. There are models with divisions from 1 to 5, from 1 to 6 and even from 1 to 7. In order not to get confused, it is important to know that the logic remains the same for all modifications: clockwise movement increases the cold.
Consider the average table of correspondence between the position of the regulator and the approximate temperature regime inside the main one cameras:
| Knob position | Operating mode | Approximate t° in the chamber | Recommendation |
|---|---|---|---|
| 1 (Min) | Economy | +5...+7°C | For storing drinks, small loads |
| 2-3 | Normal (Summer) | +3...+5°C | Standard mode for the warm season |
| 4 | Normal (Winter) | +2...+4°C | Optimal for a full load of products |
| 5-6 | Reinforced | 0...+2°C | For quick freezing or hot summer |
| 7 (Max) | Frozen | Lower 0°C | Super Freeze mode (short-term) only |
Please note that temperatures are approximate. The exact indicators depend on the serviceability of the seals, the amount of food and the frequency of opening the door. Reference point the middle position should always serve. If you have a scale up to 5, set it to 3. If up to 7, turn it to 3 or 4.
Why can’t you keep the regulator at maximum all the time?
Constant operation at maximum power leads to drying out of the oil in the compressor and cracking of plastic parts inside the chamber due to freezing and a significant increase in energy bills.
The influence of loading food on settings
Refrigerator shelves filled with food and an empty unit require different approaches to setting. The air in an empty chamber cools quickly, but heats up just as quickly when the door is opened. An array of products, on the contrary, has a high heat capacity: it takes a long time to cool down, but then holds the cold for a long time.
If you have just returned from the store with full bags, you should not immediately turn the regulator to maximum. It is better to spread the food evenly, leaving gaps for air circulation, and set the average value. The compressor itself will handle the initial cooling. An attempt to “force” the process can lead to food freezing to the walls and back panel.
If the refrigerator is not completely filled, it makes sense to slightly reduce the cooling power (move the knob to a division closer to 1 or 2). This will prevent energy from being wasted on cooling the excess volume of air that constantly changes when the door is opened.
⚠️ Attention: Never place hot or warm pots inside the refrigerator. This will not only disrupt the temperature regime for other products, but will also force the thermostat to give a command for continuous operation of the compressor, which can damage it.
Diagnosis of problems through regulator settings
Sometimes the incorrect position of the thermostat knob masks real malfunctions, or, conversely, creates their illusion. If you notice that the refrigerator Atlant is behaving strangely, carry out initial diagnostics through the settings.
- ❄️ The refrigerator does not turn off: Check whether the regulator is set to maximum. If yes, turn it down. If the position is in the middle and the motor hums continuously, there may be a freon leak or a malfunction of the thermostat.
- 💧 The chamber is too warm: If the handle is set to 4-5 and the food is spoiling, check the tightness of the door and the condition of the seal. The cause may also be a clogged drain hole.
- 🧊 Increasing “coat” of ice: A common occurrence when the regulator is set to values higher than normal. Ice acts as a heat insulator, interfering with cooling, and the compressor starts working even longer.
If after moving the regulator to the middle position (3 or 4) the situation did not return to normal within 24 hours, most likely the problem lies deeper. This may be a loss of tightness of the system or failure of the thermostatthermoregulator itself, which has ceased to correctly read the temperature.
☑️ Diagnostics of the operating mode
Saving energy and compressor life
Correct settings mean not only food safety, but also significant savings on the family budget. The compressor is the main energy consumer in the refrigerator. Working in the “every 10 minutes for 5 minutes” mode, it consumes significantly less than in the “20 minutes work, 2 minutes rest” mode.
Optimal adjustment of the regulator allows you to achieve a working time ratio of about 30-40%. This means that the unit should run less than half the time. This can be achieved by choosing the correct position of the handle depending on the season. The difference in consumption between the “Maximum” mode and the “Normal” mode can reach 20-30%.
In addition, the gentle operating mode reduces the noise level. When operating at maximum power, the vibration and hum of the motor intensify, which can cause discomfort, especially if the kitchen is combined with the living room.
Frequent questions and answers (FAQ)
What to do if there are no numbers on the regulator, only dots or marks?
In some models Atlant the scale can be indicated by dots. The logic remains the same: one point is the minimum, the maximum number of points is the maximum. Find the middle of the scale (usually the 3rd or 4th point) and set the knob there. This will be your base value for further adjustment.
Is it possible to leave the refrigerator turned off in winter on the balcony?
It is strictly not recommended to operate the refrigerator at a temperature below +5°C (for single-compressor units) or below that specified in the instructions for your climate class. The oil in the compressor thickens, which leads to failure when starting. If the balcony is unheated, the use of equipment there is unacceptable.
Why does the refrigerator take a long time to gain temperature after defrosting?
After complete defrosting, the walls and food take time to reach normal conditions. This usually takes from 4 to 8 hours. During this period, do not open the door frequently and do not add warm food. If after 12 hours the cold does not appear even on the maximum regulator, you need to call a technician.
How to understand that the thermostat is broken?
If when you turn the knob you do not hear a characteristic click (in silence), or if the refrigerator either does not turn on at all or never turns off (even at minimum), most likely the mechanics of the thermostat are broken and you need it replacement.
⚠️ Attention: Technical characteristics and temperature ranges may vary slightly depending on the specific series of the refrigerator Atlant and the year of its manufacture. Always check the device passport that comes with the kit to obtain the most accurate data for your model.
