The question of how to switch the temperature in the refrigerator Atlant, occurs quite often among equipment owners, especially after the first load of groceries or on hot summer days. Correct adjustment of the compressor operating mode directly affects the safety of products and the energy consumption of your device. An incorrect setting can lead to overfreezing of vegetables or, conversely, to spoilage of perishable food due to insufficient cooling.
Modern models of the Belarusian manufacturer are equipped with two main types of control: mechanical and electronic. Mechanical regulators are found in more budget and older series, while electronic panels with a display are typical for new products with the system No Frost. Understanding the operating principle of your specific unit is the first step to competent operation.
In this article we will analyze in detail the algorithms of action for various modifications, explain the meaning of the numbers on the regulators and answer frequently asked questions. The optimal temperature in the main chamber is considered to be in the range from +2 to +4 degrees CelsiusHowever, achieving these indicators depends on external factors and the load on the shelves.
Determining the type of refrigerator control system
Before you begin setting up, you must visually inspect the inside of the fridge compartment or the outer door panel. It is there that the control is located, which allows you to switch the temperature mode. Depending on the year of manufacture and series, you will encounter either a rotary knob or a keypad.
Mechanical thermostats are a round knob with a numerical designation from 1 to 7 (or from Min to Max). Such devices are installed in classic two-chamber models, such as Atlant MXM-1700 or MXM-2800. There is no exact value in degrees, you just set the relative intensity of the compressor.
Electronic control looks more modern and is usually located on the outside of the door or inside on the ceiling of the chamber. It allows you to set the exact temperature in 1 degree steps. Models with a display, such as the Atlant XM-6025 series, often have separate settings for the refrigerator and freezer compartments, which gives more flexibility.
⚠️ Attention: Before setting up the first time, allow the new refrigerator to sit for at least 4-6 hours after transportation. Turning on the unit immediately after skidding from the cold or after shaking during transportation can damage the compressor.
Setting a mechanical thermostat
If inside the refrigerator compartment you find a round knob with numbers, then you have a mechanical control system. The principle of its operation is extremely simple: turning the knob changes the force of the spring, which acts on the sensitive element of the thermostat. This, in turn, determines at what temperature inside the chamber the contacts will open and the compressor will turn off.
The numbers on the scale do not indicate degrees Celsius. One means the minimum cooling power (warmest temperature), and seven means maximum (coldest temperature). If the knob is set to position 0 or Off, the refrigerator will not work, since the compressor power supply circuit is broken.
For standard operation, it is recommended to set the knob to the middle position - 3 or 4. This strikes a balance between cooling efficiency and energy savings. In winter, when the room is cool, you can reduce the power to 2-3, and in summer, when it’s hot, increase it to 4-5.
The thermostat takes time (from 30 minutes to 2 hours) to react and stabilize the climate in the chamber. Therefore, you should not turn the knob back and forth in search of the ideal.
Temperature adjustment in models with electronic control
Owners of models with electronics, such as Atlant XM 4425 or XM 6021, are luckier: they can see the exact numbers on the display. Control is usually carried out using touch buttons or buttons with LEDs. The screen displays the current indicators of the refrigeration (often indicated by a snowflake symbol or letter H) and freezer (snowflake symbol with an asterisk or letter F) chambers.
To switch the temperature, you must press the mode selection button (often indicated as Mode, Temp or the image of a thermometer). After the indicator of the desired camera starts blinking, use the + and - (or Up/Down) buttons to set the desired value. A few seconds after the last press, the settings are saved automatically.
Electronics allows you to implement special modes that are not available to mechanics. For example, the Vacation mode raises the temperature in the refrigerator compartment to +10..+15°C to prevent mold while saving energy while the freezer continues to operate normally.
Some advanced models support the function Super Freeze (Super Freeze). When turned on, the compressor runs continuously, quickly freezing fresh food. However, you cannot keep this mode turned on all the time - this will lead to overloading the system and the formation of a thick ice crust.
Features of two-compressor Atlant models
A distinctive feature of many refrigerators Atlant is the presence of two separate compressors - one for the refrigerator compartment and one for the freezer. This allows you to adjust the temperature in each compartment independently of each other, which is a huge advantage over single-compressor analogs.
In such models, two separate mechanical thermostats are often installed. They can be located inside the refrigerator compartment (usually on the left or right side of the wall) and have markings. One regulator is responsible for the upper chamber, the second for the lower one. It is difficult to confuse them if you follow the labeling, but it is important to understand: turning off one does not affect the operation of the other.
Independent control makes it possible to:
- ❄️ Freeze large volumes of food in the freezer without affecting the mode of storing vegetables on top.
- 🥦 Disable the refrigerator compartment in the summer, if it is not needed, leaving only the freezer running.
- 🔇 Reduce noise by turning off one of the compressors at night if the second is not required to maintain temperature.
When setting up a two-compressor system, the thermal load should be taken into account. If you have loaded the freezer with indoor products, turn on the fast freezing mode specifically for the lower circuit, without touching the settings of the upper chamber.
Table of recommended temperature conditions
To preserve the taste and healthiness of products, it is important to adhere to certain temperature ranges. Below is a table that will help you figure out what temperature to set on the display or what number to select on the mechanical regulator (average).
| Product type | Recommended temperature (°C) | Storage area | Shelf life (approximate) |
|---|---|---|---|
| Fresh meat, fish | 0.. +2 | Zero zone / Bottom | 1-3 days |
| Dairy products | +2.. +4 | Middle shelves | 3-7 days |
| Vegetables, fruits | +4.. +6 | Drawers below | 3-10 days |
| Ready meals | +2.. +5 | Top shelves | 1-2 days |
It is worth noting that in mechanical refrigerators it is difficult to achieve exact compliance with these figures. The rule works here: the closer to the evaporator (back wall), the colder it is. Therefore, it is better to place milk away from the back wall, and meat, on the contrary, closer to the source of cold.
☑️ Checking the correct settings
Common problems and ways to solve them
Sometimes users are faced with a situation where seemingly correct settings do not give the expected result. The refrigerator is too warm or, conversely, everything freezes. Before calling a technician, it is worth checking several basic parameters that are often ignored.
One of the common causes of temperature violations is a loose door fit. If the rubber seal is dirty, worn or deformed, cold air escapes and warm air enters. The compressor tries to compensate for the loss by working non-stop, but it never reaches the desired temperature.
Another common mistake is installing hot or warm products. If you place a pot of just-cooked soup in the chamber, the thermostat (especially a mechanical one) may not have time to react, and the temperature in the chamber will rise critically. This will cause the compressor to wear out.
⚠️ Attention: Never set the temperature control to maximum (7 or Max) to quickly freeze fresh food, unless the instructions for your model indicate otherwise. This can lead to freezing of the evaporator and damage to the thermostat. For quick freezing, use a special mode, if available.
It is also worth checking the location of the refrigerator. If it stands close to the wall, the radiator (grille at the back) is not cooled by air. Efficiency drops, and switching the temperature to a lower one becomes physically impossible - the equipment is working at its limit.
Why does the thermostat click?
The characteristic click when a mechanical refrigerator is operating is the sound of the thermostat contacts opening or closing. If the clicks become too frequent or, on the contrary, disappear completely (and the compressor does not turn on), perhaps the thermostat is faulty and requires replacement.
The influence of external factors on the operation of the refrigerator
The temperature in the room where it is located Atlantplays a colossal role. Most household refrigerators are designed to operate in climate class N (Normal), that is, at ambient temperatures from +16°C to +32°C. If the room is colder than +10°C, the oil in the compressor thickens, and it may not start or quickly fail.
In the summer, when the apartment is +30°C and above, the refrigerator has to work harder. In such conditions, it makes sense to turn the mechanical knob 1 notch in the direction of increasing power. However, make sure that the compressor does not work without interruption - this is a signal of overload or freon leakage.
Direct sunlight falling on the housing also heats the unit. In this case, even the maximum setting may not help. It is better to move the refrigerator into the shade or shade the window than to drive the equipment at maximum settings.
What to do if, after switching the temperature, strong ice appears?
Formation of a “fur coat” of ice often indicates that the temperature is set too low for current conditions, or the door seal is broken. Ice can also build up if you frequently open the door in a room with high humidity. Try reducing the power (lower the number on the regulator) and defrosting the refrigerator completely (for 24 hours with the power turned off).
Is it possible to completely turn off the freezer in a two-compressor Atlanta?
Yes, in most two-compressor models this is possible. To do this, you need to find the thermostat that is responsible specifically for the freezer compartment (usually it is smaller in size or has the appropriate marking), and turn it to position 0 or Off. The upper chamber will continue to operate as usual.
Why is the temperature on the display blinking?
Flashing numbers on the electronic display Atlant usually indicate an alarming condition. Most often this means that the actual temperature in the chamber is higher than the set temperature (for example, after defrosting or loading warm food). Once the camera has cooled down to the set temperature, the flashing will stop. If the blinking does not stop for a long time, check the tightness of the door closure.
How often should you check the temperature settings?
It is enough to check the relevance of the settings when changing the season (summer/winter), after completely defrosting the refrigerator or when changing the usual set of products. The rest of the time, if the equipment is working properly, intervention in the operation of the thermostat is not required.
