Owners of household appliances are often faced with the need to change the standard operating parameters of the unit in order to extend the shelf life of products or adapt the device to the summer heat. Adjusting the Atlant refrigerator - a process that does not require calling a technician, but requires a precise understanding of the principles of operation of the thermostat and defrosting system. Many users mistakenly believe that simply turning the knob is enough, but different models have their own nuances, ignoring which can lead to damage to the compressor or poor-quality cooling.
Correct setting temperature conditions directly affects energy consumption and the preservation of the taste of food. If the chamber is too warm, bacteria multiply faster, and if it is cold, the food freezes and loses its structure. In this article, we will look in detail at how to manage the settings of various series, from classic two-chamber models to modern units with the No Frost system, so that you can achieve an ideal microclimate inside.
The design and principle of operation of the thermostat
The main element responsible for maintaining cold is is thermostat (thermostat). It is he who reads the temperature inside the refrigerator compartment and gives the command to the compressor to turn on or off. In classic models Atlant this device is a mechanical device with a rotary knob, usually located inside the camera or on the front panel. The principle of operation is based on the expansion and contraction of the sensitive element (bellows) under the influence of heat.
When you turn the knob, you change the spring tension, which shifts the contact threshold. It is important to understand that the numbers on the scale (usually 1 to 7 or Min to Max) do not represent degrees Celsius. They indicate the intensity of work: the higher the number, the lower temperature inside and longer the motor works. The mistake of many is to try to set the maximum value immediately after loading the products, which creates an excessive load on the system.
⚠️ Attention: Abruptly moving the thermostat knob from minimum to maximum can lead to water hammer in the refrigerant circulation system. Change the settings smoothly, at intervals of 30-40 minutes.
In more modern models, control can be carried out by an electronic module, where data from the sensors is displayed. Here temperature adjustment happens with an accuracy of a degree, and the system itself controls the operating time of the compressor, preventing overheating. However, even in such systems, mechanical elements may require calibration during long-term operation.
Adjusting the temperature in the refrigerator compartment
The optimal temperature for storing most products in the main chamber is considered to be the range from +2 to +4 degrees Celsius. To achieve these indicators in mechanical models, the thermostat knob should be set to the middle position. If you are using a model with divisions from 1 to 7, then the “golden mean” is usually a value of 3 or 4. This provides a balance between cooling quality and energy consumption.
When filling the chamber with a large amount of food or in the hot season, you may need to increase the cooling. In this case, the regulator can be shifted towards larger values. However, it is worth remembering that maximum power mode is not intended for permanent work. Long-term operation at the maximum capacity reduces the life of the compressor and leads to the formation of an ice crust on the back wall.
- 🌡️ For everyday storage of food (milk, cheese, ready meals), it is enough to set the regulator to the middle value.
- ❄️ When loading a large volume warm (but not hot!) products, you can temporarily increase the power by returning the settings after 5-6 hours.
- ☀️ In the summer, when the temperature in the kitchen exceeds +25°C, it makes sense to add 0.5-1 division to the current setting.
If you notice that the products at the back wall are freezing, and on the contrary, they are getting warmer at the door, this is a signal about the need for adjustments. Try reducing the power by one notch and checking the cold distribution after a day. Also make sure that you do not block the air ducts if your model provides air circulation.
Adjusting the freezer compartment and quick freezing
The freezer compartment requires special attention, since it is critical to maintain the temperature below -18 degrees. In models Atlant with a separate regulator for the freezer (often this is the lower cap or second handle), the settings are similar to the main chamber: more numbers - colder. However, the rule here is: the lower the temperature, the higher the energy consumption.
The function quick freezing (Super Freeze) allows you to lower the temperature to -24...-26 degrees. This is necessary when loading large quantities of fresh products so that they undergo crystallization quickly and preserve the cell structure. In mechanical models, to activate this mode, the handle is moved to the extreme position (often indicated by an asterisk or number 7), and in electronic models, the corresponding button is pressed.
| Operating mode | Knob position | Temperature (approximate) | Duration of use |
|---|---|---|---|
| Economy | 1-2 (or Min) | -12...-15°C | Light load |
| Normal | 3-4 (Average) | -18...-20°C | Continuous mode |
| Intense | 5-6 | -22...-24°C | Heat or full load |
| Super freezing | 7 (Max) | below -24°C | No more than 12-24 hours |
It is important not to forget to turn off the super-freeze mode after completing the cycle (usually 12-24 hours). If you leave the refrigerator in this mode, compressor it will work continuously, which will lead to its overheating and possible failure. In models with electronics, this mode is often turned off automatically, but the mechanics must be controlled manually.
☑️ Checking the freezer settings
Features of setting up the No Frost system
Refrigerators Atlant with system No Frost (or Partial No Frost) have a fundamentally different cold distribution scheme. There is no need to monitor the formation of ice on the walls, since moisture is removed automatically. However, temperature control in such models is often hidden behind the control panel or requires more precise settings.
In electronically controlled models, you set the target temperature, and smart electronics decide how long the compressor should run. Mechanical versions of No Frost also use thermostats, but they may be calibrated differently. Often in such refrigerators there are dampers that regulate the flow of cold air from the freezer to the refrigerator compartment.
⚠️ Attention: In No Frost refrigerators, you cannot completely block the ventilation holes inside the chamber with food. This will disrupt air circulation and lead to local overheating or, conversely, freezing.
If you notice that the temperature in the refrigerator compartment Atlant No Frost floats, check whether the air ducts are clogged with ice. Sometimes it is necessary to defrost the unit (complete shutdown for 10-12 hours) to clean the defrost channels. After turning on, let the refrigerator get cold for 2-3 hours without loading food.
Why does ice still appear in No Frost?
Ice in the No Frost system can appear only in two cases: if the defrosting heating element is faulty or if the door does not close tightly, allowing moist air to pass through. Adjusting the temperature will not help here; repair or replacement of the seal is needed.
Seasonal adjustment and operating conditions
External conditions play a huge role in the operation of refrigeration equipment. In winter, when the apartment is cool, the refrigerator may turn on less often, which sometimes leads to the food in the freezer thawing. In the summer, at high air temperatures, heat exchange is difficult, and the unit is forced to work more intensely. Seasonal adjustment helps compensate for these differences.
In the summer, it is recommended to check the temperature inside the chambers more often. If you feel that the motor is running almost non-stop and the inside is not getting any colder, you may need to clean the condenser (the grille at the back) of dust rather than changing the thermostat settings. A dirty heat exchanger is a common cause of ineffective operation.
- 🍂 In autumn and spring, when the heating operates moderately, return the settings to standard values (3-4 divisions).
- ☀️ In summer, make sure that the refrigerator does not stand next to the stove or in direct sunlight - this will negate any adjustments.
- ❄️ In winter, if the room is cold (+15°C and below), some models may not turn on at all. In such cases, it may be necessary to install a special winter kit.
Remember that climate class your Atlant refrigerator determines the permissible range of ambient temperatures. This information is located on a label (sticker) inside the camera or on the back. Exceeding these limits makes the warranty invalid and may lead to breakdown.
Diagnostics of problems after adjustment
After you have made adjusting the refrigeratorit is important to control the result. Don't expect immediate changes—temperature stabilization in large-volume chambers can take 4 to 8 hours. If after this time the situation has not changed, perhaps the problem lies deeper than just the settings.
Among the common symptoms of incorrect adjustment or malfunction are: the formation of a “snow coat” on the food, lack of cold when the motor is running, or vice versa - turning on and off too often (clocking). In the first case, it is worth reducing the power, in the second, check the tightness of the door, and in the third, perhaps the thermostat has failed.
⚠️ Attention: If, after adjustment, the compressor runs for more than 20 minutes without a break, and the temperature does not drop, immediately unplug the device. Long-term operation in this mode can burn the motor winding.
For accurate diagnosis, use a household thermometer, placing it in a glass of water in the center of the chamber. This will provide objective data, as opposed to tactile sensations. If the thermometer readings diverge greatly from the set mode even after a day of operation, you need to call a specialist to check thermostat or the amount of freon.
What to do if the regulator rotates endlessly?
If the thermostat knob rotates in a circle without clicks and restrictions, most likely the regulator mechanism itself has broken. In this case, adjustment is impossible - the part needs to be replaced.
Frequently asked questions (FAQ)
How to understand that the thermostat is broken?
Main symptoms: the refrigerator does not turn on at all (and there is a light inside), or it turns on and works non-stop, without turning off even at low temperatures. Also, a sign of a malfunction may be the absence of a characteristic click when turning the knob.
Is it possible to adjust the temperature while the refrigerator is running?
Yes, the mechanical thermostat Atlant can be turned in any position, even on the go. However, sudden movements are undesirable. Electronic settings also change in real time, but take effect immediately.
Why does water freeze in the refrigerator compartment?
Most likely, the temperature regulator is turned to the maximum (6-7) or the thermostat itself is faulty (contacts are stuck). Try lowering the value to 2-3. If the problem persists after a day, diagnostics is needed.
Do you need to change the settings when you turn it on for the first time?
When you turn it on for the first time, it is recommended to set the average value (3 or 4) and let the refrigerator run empty for 2-3 hours. After loading the products, you can fine-tune it to your needs.
Does overcrowding the chamber affect the temperature?
Yes, a full chamber keeps the cold longer, but it takes longer for the initial cooling. An empty refrigerator turns on less often, but when the door is opened, the temperature in it fluctuates more. The optimal load is 50-70% of the volume.
