Two-compressor models of refrigeration equipment of the brand Atlant are deservedly very popular due to their reliability and the ability to independently control temperature conditions. This design feature allows owners to flexibly customize the operation of the unit to suit their needs, up to completely turning off one of the compartments. Most often, users are interested in how to correctly and safely turn off the fridge compartmentleaving the freezer running, for example, to save energy or during a long absence.
Unlike single-compressor systems, where such functionality is often absent or implemented through "Vacation" mode; in models with two motors, this process is extremely simple and does not require complex manipulations with electronics. Understanding the principle of operation thermostat and knowledge of the location of control elements is the key to the correct operation of your equipment. In this article, we will analyze the algorithm of actions in detail, consider the features of the various series and answer frequently asked questions.
The principle of operation of a two-compressor system
The main difference between a dual-circuit cooling system is the complete autonomy of the circuits. One compressor with its own evaporator is responsible for cooling the upper compartment, and a second, independent unit is responsible for freezing food in the lower zone. This means that thermostat the refrigerator compartment controls exclusively its motor, without affecting the operation of the freezer in any way.
This scheme provides a huge advantage: you can theoretically turn off one of the circuits, and the second will continue to operate normally. This is especially true for models Atlant XM-4008, XM-4423 and others equipped with mechanical or electronic regulators. When the thermostat knob is turned to position "0" or "Off", the power circuit of the corresponding compressor is opened.
It is important to understand that even when the upper compartment is turned off, the cold from the operating freezer can be partially transferred to the adjacent compartment through a common partition. However, there will not be full cooling and air circulation in the upper part. Independent circuits guarantees that the products in the freezer will not suffer from manipulations with the upper compartment.
Location of controls in different models
Before you begin setting up, you must accurately determine the control type of your model. In refrigerators Atlant there are two main types of regulators: mechanical (rotary) and electronic (with a display). The location of these elements may vary depending on the year of manufacture and series of the device.
In classic mechanically controlled models, temperature controllers are usually located inside the refrigeration chamber. They are rotary knobs, often located in the upper right corner of the interior volume or on the ceiling of the compartment. Next to them there may be a quick freezing button, which in two-compressor models is responsible only for the freezer.
If you have a modern model with electronic control, then the display and button panel is located on the outer door. In such cases, the camera is turned off by long pressing the corresponding button or through the settings menu. Always check the product data sheet, as control interface may differ.
⚠️ Attention: In some older models, the mechanical thermostat may be hidden behind a decorative trim or have a tight movement. Do not use excessive force when turning the handle so as not to break the plastic rod.
For clarity, let's look at the main differences in control:
- 🔹 Mechanical models: control through a thermostat handle inside the chamber.
- 🔹 Electronic models: control through an external panel with display.
- 🔹 Combined: mechanics inside, but with an indication on the door (rarely).
Instructions: turning off with a mechanical thermostat
If your refrigerator is equipped with a classic rotary handle, the shutdown process will take a few seconds. Locate the temperature control inside the refrigerator compartment. Usually it has a scale from 1 to 7 (or from Min to Max), where number 1 is the minimum cooling, and 7 is the maximum.
To completely turn off the circuit, you must turn the knob counterclockwise until it stops. In this position, you will hear a slight click and the pointer will move to the “0” or “Off” mark. This means that the electrical circuit is broken and the upper chamber compressor will no longer receive a signal to start.
After moving the regulator to the zero position, the running motor may make another stopping sound after a while, as the refrigerant needs time to be redistributed in the system. Make sure the handle is locked in the leftmost position. If it scrolls freely without a click, the regulator mechanism may be faulty.
☑️ Algorithm for turning off the mechanics
It is worth noting that even when the thermostat is turned off, the light bulb in the chamber may continue to light if it is powered from a separate circuit. This is normal and does not indicate a malfunction. The main thing is that it does not start compressor and frost does not form on the back wall.
Setting up electronic control and the "Vacation" mode
In models with electronic control, the procedure may differ. There is no physical breaking of the circuit by turning the knob; all commands are processed microprocessor. To turn off the refrigeration chamber, a special mode is often used, which in the documentation may be called “Vacation”, “Eco” or simply indicated by the icon of a crossed out chamber.
Activation of the mode is usually done by long pressing (3-5 seconds) the button with the corresponding symbol on the external panel. The display may indicate "OFF" in the sector responsible for the refrigerator compartment. In some models Atlant it is necessary to successively press the temperature selection button; the shutdown symbol will not appear.
The electronic system itself controls the process. Once the command is activated, the control unit stops supplying voltage to the upper circuit compressor. It is important to wait for confirmation from the system - a sound signal or a change in the display. If the display is flashing, it means the command was not accepted or the settings are being reset.
Why is the indicator flashing after shutting down?
If the indicators continue to flash after attempting to shutdown, this may mean that the door is not tightly closed or the door open alarm has tripped. Check the seals and make sure the door is completely closed before repeating the procedure.
Unlike mechanics, an electronic thermostat allows you to more accurately control the process. However, it should be remembered that electronics are sensitive to power surges. If, after turning off the camera, the display does not behave correctly, try turning off the power to the refrigerator for 10-15 minutes to reboot the system.
Comparison of models and technical characteristics
Different series of refrigerators Atlant may have their own design features. Below is a table that helps identify the capabilities of your model by type of control and the presence of independent circuits.
| Series / Model | Type of control | Independent shutdown | Location of the regulator |
|---|---|---|---|
| Atlant XM-4008 | Mechanical | Yes (knob 0-7) | Inside, top right |
| Atlant XM-4423 | Electronic | Yes (OFF mode) | On the external door |
| Atlant XM-6021 | Mechanical | Yes (knob 0-7) | Inside, chamber ceiling |
| Atlant XM-4208 | Mechanical | Yes (knob 0-7) | Inside, on the right |
As can be seen from the table, most two-compressor models support the independent control function. However, in the most budget or specific modifications (single-circuit systems with one compressor), turning off one chamber without stopping the entire unit is impossible. Always check the technical data sheet.
Energy savings and conservation products
Disconnecting the refrigerator compartment is a great way to save energy if you are leaving for a long period of time or store food on the balcony in winter (provided that the temperature there does not fall below the permissible temperature for the compressor to operate). However, an empty chamber can become a source of unpleasant odors or mold.
Before disconnecting the circuit, it is recommended to completely defrost and wash the interior. Leave the refrigerator door slightly open to allow air circulation and prevent mustiness. To do this, you can use a special clamp or simply place a small board.
If you turn off the camera temporarily (for several days), make sure that there are no quickly perishable products left in it. Even when the compressor is turned off, the temperature will increase gradually, but the risk of bacterial growth will remain. Hygiene in this case, saving is more important.
⚠️ Attention: Do not store foods that require low temperatures in the switched off chamber, even if the freezer is running. The temperature in the upper compartment will quickly become equal to room temperature, which will lead to food spoilage.
It is also worth considering that a working freezer will give off heat through the body and partition. Therefore, when the refrigerator compartment is turned off, it may be warmer than the rest of the room. This is a normal physical process of heat transfer.
Frequently asked questions (FAQ)
Is it possible to turn off only the freezer, leaving refrigeration?
Technically, this is possible by moving the freezer regulator to the "0" or "Off" position. However, manufacturers do not recommend leaving food in the refrigerator compartment when the freezer is turned off, as this upsets the overall balance of the system, although for dual-compressor models this is less critical than for single-compressor models.
Will the light in the chamber work if I turn off the thermostat?
Yes, the lighting is usually powered directly from the mains and not depends on the position of the thermostat knob. The light will come on when the door is opened, even if the compressor is turned off. To turn off the light, you will have to keep the door closed or remove the light bulb.
Why is it still a little cold after turning off the camera?
This is due to heat exchange with the working freezer and the common internal partition. Cold air from the bottom can sink or be transmitted through the walls. This does not mean that the upper chamber compressor is working.
Do you need to defrost the refrigerator before completely turning it off?
If you plan to completely disconnect the refrigerator from the network, it is necessary. If you only turn the thermostat to “0”, but leave the plug in the socket (the freezer is running), then defrosting the upper chamber is desirable for hygiene, but is not necessary for the safety of the device.
Is frequent switching on and off harmful for the compressor?
Sudden changes in modes are undesirable, but normal operation turning off via the thermostat (handle) does not harm the equipment. However, it is not recommended to turn the knob back and forth every 5 minutes. Allow the system to stabilize. It is optimal to leave the mode unchanged for at least several hours.
