Owners of two-chamber refrigerators Atlant often face the need to change the operating mode of the freezer compartment. This may be required to save energy, perform defrosting, or temporarily use the device solely as a refrigerator. However, the design of these units does not always provide for the complete and independent shutdown of one of the cooling circuits without losing the functionality of the other.
Understanding the principle of operation No Frost systems or static cooling helps to avoid mistakes that can lead to compressor failure or defrosting of food in the main compartment. In this article, we will analyze in detail the technical capabilities for controlling the freezer compartment, available for various series of Belarusian-made equipment.
It is worth noting right away that complete electrical shutdown of the freezer while the refrigerator is running is impossible in standard household models, since the refrigerant circulates through a single circuit or is controlled by a single compressor. However, there are ways to minimize energy consumption or change the temperature regime, which will be discussed below.
The principle of operation of the Atlant cooling system
Most refrigerator models Atlant, especially two-chamber ones, operate on the basis of a single compressor, which pumps refrigerant into the evaporator. Even in systems with two compressors, control is often tied to a single logic center or thermostats working in conjunction. When you try to “turn off” the freezer, you actually disrupt the freon circulation cycle, which can lead to overheating of the motor.
The temperature in the freezer is regulated either by a mechanical thermostat or an electronic control unit. In mechanical models, turning the knob to the “0” or “Off” position usually stops the operation of the entire refrigerator, and not a separate chamber. This is a critically important nuance that must be taken into account before starting any manipulations with the settings.
⚠️ Attention: An attempt to physically disconnect the defrost heater or sensor in the freezer in order to stop its operation will lead to the formation of an ice coat and failure of the system.
Electronic control allows you to more flexibly configure parameters, But even here there are strict restrictions. The controller's operating algorithms are programmed to maintain the minimum required temperature to preserve food. If the system detects anomalies (anomalies) in the form of too high a temperature in one of the zones, it can increase the compressor power, which will negatively affect another zone.
Mechanical control: thermostats and their capabilities
In classic models Atlant with mechanical control, the temperature regime is set by a rotary knob inside the refrigerator camera or on the front panel. The adjustment range is usually from 0 to 7 or from Min to Max. It is important to understand that these numbers indicate the cooling intensity, and not degrees Celsius directly.
The position of the knob "0" or "Off" opens the electrical circuit of the thermostat, completely stopping the compressor. There is no separate handle for turning off only the freezer compartment in such models. The only way to reduce the temperature in the freezer is to reduce the overall intensity of operation, but this will lead to an increase in the temperature in the refrigerator compartment.
There are models with two thermostats, but they are rare and usually belong to older or specific modifications. In such cases, the second regulator may be responsible for “Super Freeze”, but not for complete shutdown. Using the superfreeze mode, on the contrary, forces the compressor to work without stopping, ignoring temperature shutdowns.
- 🌡️ A standard thermostat controls the temperature of the evaporator, not a separate chamber.
- ❄️ The "Superfreeze" mode (button with a snowflake) forcibly turns on the compressor for a long time time.
- 🔌 Complete shutdown occurs only when all controls are moved to position "0".
If your goal is to save energy, then reducing the thermostat setting to the minimum values (1 or Min) will be the safest option. However, this will not stop the freezing process completely, but will only slow it down, allowing the temperature in the chamber to rise to -6...-10°C, which is not enough for long-term storage of meat, but acceptable for vegetables or ready-made products.
Electronic control and display panels
Modern refrigerators Atlant XM series and others equipped with an electronic control unit with a digital display. Here the temperature is adjusted to the nearest degree. The user interface may allow you to independently set the temperature for the refrigerator and freezer compartments, but the physical principle of cooling remains the same.
Attempting to set the temperature in the freezer compartment as high as possible (for example, +5°C or +10°C, if the model allows it) will effectively turn it into an additional refrigerator compartment. However, not all models support such a wide range of adjustment. Typically, the upper limit for a freezer is limited to -6°C or -10°C.
Sequence of settings (example):1. Press the "Lock" button to unlock.
2. Select the "Freezer" zone.
3. Use the "+" or "-" buttons to set the value.
4. Wait 5-10 seconds before saving.
Some advanced models have a “Vacation” mode. When activated, the refrigerator compartment goes into economy mode with a temperature of about +15°C to prevent the formation of mold, and the freezer continues to operate normally. There is usually no reverse mode, when the freezer sleeps and the refrigerator is working, in standard firmware. Atlant usually not.
Why can’t you completely turn off the freezer programmatically?
Manufacturers do not provide this function, since the evaporator design is often common or located in the freezer area. Turning off the circulation of air or refrigerant will lead to defrosting of food in the refrigerator and overloading the compressor.
Using the "Super Freeze" mode and its reverse effect
Mode Super Freeze (Super Freeze) is often confused with the ability to control the operation of the chamber. In fact, this function is designed to quickly freeze large quantities of fresh food. When this function is enabled, the refrigerator ignores the current temperature and operates continuously.
Understanding the operation of this mode is important for those who want to know how to do it turn offif it was activated accidentally. On mechanical models, the yellow light comes on and the compressor does not shut off. In electronic models, the mode can be turned off automatically after a certain time (usually 24-72 hours) or manually by pressing the button again.
| Control type | Indication | Action to turn off | Auto shutdown time |
|---|---|---|---|
| Mechanical | Yellow indicator | Press the button again | No (works manually) |
| Electronic | Symbol flashing | Select mode and press OK | 24-72 hours |
| Touch | Button backlight | Touching the button functions | Depends on the model |
| No function | Absent | Not applicable | Not applicable |
If you accidentally enabled this mode, The freezer will work hard, consuming maximum electricity. Therefore, unless you plan to freeze 10 kg of meat right now, make sure that the super freeze indicator is off. Long-term operation in this mode reduces the life of the compressor.
The defrosting procedure as a method of temporary shutdown
The only legal way to completely “turn off” the freezer while still being able to use the refrigerator (albeit with restrictions) is to perform a complete defrost. This process requires time and preparation, but it allows you to clear the unit of ice and temporarily stop cooling.
First, you need to disconnect the refrigerator from the power supply. Then you should remove all food from the freezer. If you want the main compartment to continue to work, and the freezer to defrost, this will not work - when defrosting, the entire appliance turns off.
☑️ Checklist for safe defrosting
After the ice has melted and the internal surfaces dry, you can turn on the refrigerator again. If you do not load food into the freezer and close its door, the temperature there will begin to rise slowly, but the compressor will still turn on periodically to maintain cold in the main compartment, slightly freezing the empty compartment.
⚠️ Attention: Never use sharp objects (knives, screwdrivers) to chip ice in the freezer. Damage to the evaporator will lead to freon leakage and costly repairs.
Energy saving and alternative solutions
If your goal is to save energy and you do not use the freezer, the best solution would be to completely defrost it, dry it and leave the door slightly open (if the design and safety allow) so that the compressor does not try to cool the empty space. However, as we have found, it is difficult to separate the contours.
An alternative is to set the temperature in the freezer to the highest possible value (for example, -6°C), if the model allows it. This will reduce the load on the system. It is also worth checking the door seals: if they do not fit tightly, the cold goes away and the compressor runs more often.
In the long term, if you don't need a freezer at all, consider buying a separate refrigerator without a freezer (for example, for storing drinks or medications) or using the freezer as an additional cabinet for vegetables, setting it to the minimum cold setting.
Frequently asked questions (FAQ)
Is it possible to physically disconnect the freon supply hose to the freezer?
Theoretically, this is only possible for a qualified technician with equipment for vacuuming and filling the system. Independent intervention in a sealed circuit will lead to an immediate loss of refrigerant, moisture entering the system and failure of the compressor. This is impractical and dangerous.
Why does the freezer not get cold for a long time after defrosting?
After complete defrosting and turning on, the refrigerator takes time (from 2 to 10 hours depending on the model and amount of refrigerant) to reach operating mode. At this time, it is not recommended to load food so as not to create unnecessary heat load.
Does filling the freezer affect energy consumption?
Yes, a full freezer is more economical than an empty one. Foods (especially frozen ones) accumulate cold and act as thermal insulators. In an empty chamber, each time the door is opened, cold air is quickly replaced by warm air, causing the compressor to work harder.
What to do if the freezer has stopped freezing, but the refrigerator is working?
This is a sign of a malfunction. Possible reasons: freon leak, capillary tube clogged, thermostat malfunction or problems with the defrost system (in No Frost). It is necessary to call a technician for diagnostics, since operation in this mode will lead to damage to the products.
