The refrigerator is the heart of a modern kitchen, maintaining food freshness and the safety of your food. Owners of Belarusian brand equipment Atlant often face the need to fine-tune the temperature, especially when changing seasons or after the cameras are fully loaded. Correct adjustment directly affects the energy consumption and service life of the compressor.
Unlike complex electronic systems, mechanical models require the user to understand the physical principles of the thermostat. Incorrect setting can lead to either excessive energy consumption or damage to perishable products. In this article we will look at the nuances of climate control inside your refrigeration unit.
Many users mistakenly believe that it is enough to simply turn the knob to the maximum value. However, different models, be it a classic two-chamber Atlant MHM 2808 or more modern series, have their own characteristics. Let's figure out how to find the “golden mean” for ideal storage.
The principle of operation of a mechanical thermostat
The main control element in most models Atlant is a mechanical thermostat. This device is a relay that opens the electrical circuit when a set temperature is reached and closes it when heated. Inside the case there is a sensitive capsule with gas or liquid that responds to thermal expansion.
When you turn the knob, you physically change the pressure on the mechanism spring, setting the response threshold. Scale from 0 to 7 (or from Min to Max) does not display degrees Celsius directly. The numbers indicate the intensity of the compressor: the higher the number, the lower the temperature inside the chamber and the longer the motor operates.
It is important to understand that the thermostat responds to the temperature of the evaporator or air at a specific point, and not to the average temperature in the chamber. Therefore, placing products near the sensor can distort the readings and cause frequent engine starts.
⚠️ Attention: Suddenly moving the thermostat knob immediately to maximum can lead to the formation of a “snow coat” on the back wall and freezing of products. Change the settings smoothly, at intervals of several hours.
In some modifications, for example, in the series Atlant 4008, a dual-circuit regulator is installed, which allows you to independently (albeit roughly) control the cooling of the refrigeration and freezer chambers, if the design provides for such a possibility through the distribution system cold.
Why does the thermostat click?
The click you hear is the normal sound of the contacts opening or closing inside the relay. If the clicks become very frequent (every 2-3 minutes), this may indicate a freon leak or a malfunction of the thermostat itself.
Decoding the temperature scale
Understanding the numerical values on the regulator is the key to success. The standard scale for refrigerators Atlant usually ranges from 1 to 7, where 1 is the minimum cooling (the warmest temperature) and 7 is the maximum (the coldest temperature). The “0” or “Off” position completely turns off the power supply to the compressor.
The optimal operating range for everyday use is considered to be the handle position between 3 and 4. In this mode, the refrigerator compartment maintains a temperature of about +3...+5°C, which is ideal for most products. The freezer freezes food to -18°C and below.
If you set the regulator to 6 or 7, the compressor will work almost non-stop, trying to achieve a minimum that is unattainable under normal conditions. This leads to freezing of the melt water drainage channel and overload of the electrical network.
To store a large amount of food in the freezer or quickly freeze fresh berries, you can temporarily switch the regulator to position Max or 7. However, do not keep the equipment in this mode for more than 6-8 hours to avoid damage.
Seasonal adjustment of settings
Ambient temperature directly affects the operation of refrigeration equipment. In summer, when the apartment is hot, heat inflows increase and the compressor takes more time to cool the chambers. In winter, the situation is the opposite: in a heated room the load is less, but there are nuances with the location of the equipment.
In the summer, it is recommended to move the thermostat knob closer to higher values (4-5) if you notice that the food in the refrigerator compartment begins to thaw or the milk quickly sours. However, make sure that an excessive layer of ice does not form on the back wall.
In winter, especially if the refrigerator is located close to the radiator or in the sun, the settings may require reducing the intensity (2-3). If the equipment is in a cool place (for example, on an insulated balcony, although this is not recommended for most models), the compressor may not turn on at all. Atlant), the compressor may not turn on at all.
Seasonal changes require not only turning the knob, but also monitoring the filling of the chambers. An empty refrigerator cools down faster, but it also heats up instantly from the warm air when the door is opened. Loading stabilizes the temperature background.
Instructions: how to set the temperature correctly
The setting process is simple, but requires consistency. First, make sure the refrigerator is plugged in and working. If you have just defrosted the appliance or turned it on for the first time, let it operate for 5-6 hours in normal mode before making the first adjustment.
Find the thermostat. In classic models Atlant it is located inside the refrigerator compartment, usually in the upper right corner or on the ceiling of the chamber. In some older models, the handle may be located outside, above the door.
☑️ Setting algorithm
Turn the knob to the desired position. To start, choose the average number (usually a number of 3 or 4). Don’t try to set the “ideal” right away; it’s better to do it in two stages. After turning the knob, listen: after a while the compressor should start or, conversely, stop.
If you change the settings, be sure to wait a few hours (usually the cycle is from 30 minutes to 2 hours of work and the same amount of rest) for the system to stabilize. You should not expect an instant result due to the inertia of the system.
⚠️ Attention: Never try to remove the regulator handle or pick the mechanism with a screwdriver when the refrigerator is plugged in. This may lead to a short circuit or damage to the capillary tube of the thermostat.
Features of models with electronic control
Modern refrigerators Atlantsuch as the series XM-6025 or XM-4425, are equipped with electronic control panels. Here the adjustment occurs not mechanically, but through digital sensors and a display. The accuracy of such systems is much higher.
On the display you can see the exact temperature in degrees Celsius. Typically, the setting range for the refrigerator compartment is from +3°C to +8°C, and for the freezer from -15°C to -24°C. Control is carried out by touch buttons or mechanical keys next to the screen.
To change parameters, you need to press the mode selection button (often indicated as Freeze for the freezer or Cool for the refrigerator) and hold it or use the “+” and “-” buttons. The numbers on the screen will begin to flash, signaling readiness for input.
Electronics allows you to activate the “Super Freeze” or “Vacation” modes. Mode "Vacation" turns off the refrigerator compartment, leaving only the freezer working, which saves energy during your long absence.
Diagnostics of problems with temperature conditions
If you notice that the food in the refrigerator compartment is freezing (especially vegetables at the back wall) or, conversely, quickly deteriorating, and the regulator is in the middle position, this is a signal of a malfunction. A common cause is a refrigerant leak or thermostat failure.
If there is a freon leak, the compressor works almost non-stop, trying to gain temperature, but there is no cold. In this case, twisting the thermostat knob will not produce results - the equipment will hum, but not cool. You need to call a technician to find a leak and refill it.
If the compressor turns on very rarely, and the chamber is warm, the contacts of the thermostat may have become “stuck” or the sensitive capsule has lost sensitivity. In mechanical models Atlant replacing the thermostat is a standard and inexpensive repair procedure.
| Symptom | Possible cause | Action |
|---|---|---|
| Food freezes at the back wall | The mode is too strong or the damper is faulty | Reduce the regulator value, check the seal |
| The compressor works without stopping | Freon leakage or thermostat failure | Call a technician, do not operate for a long time |
| The chamber is warm, the motor is silent | Thermostat malfunction (does not close the circuit) | Replacing the thermostat |
| Frequent on/off | The capacitor is clogged or the sensor is faulty | Clean the grille at the back, check the ventilation |
Frequently asked questions and answers (FAQ)
Why ice freezes in the Atlant refrigerator even at a minimum temperature?
This may indicate a loose door fit (wear of the seal), frequent opening of the door, or a malfunction of the melt water drainage system (clogged drainage hole). Also check whether the products are adjacent to the back wall.
What temperature should be in the Atlant freezer?
The optimal temperature for long-term storage is -18°C. For short-term storage of meat (up to 2-3 days), -6...-12°C is enough, which corresponds to the “one star” mode on the door.
Is it possible to replace a mechanical thermostat with an electronic one in Atlanta?
Theoretically it is possible, but it requires a deep reworking of the control system, drilling holes and selecting compatible sensors. The plant does not provide for such an upgrade, and there will be no guarantees for operation after such an intervention.
What does the flashing temperature indicator on the display mean?
Flashing usually signals an increase in the temperature in the chamber above the permissible threshold. This could be after defrosting, loading warm food or if there is a malfunction. If the blinking does not stop after a day of operation, diagnostics are needed.
