Modern two-chamber refrigerators Atlant are often equipped with a function that allows you to temporarily turn off one of the chambers, which is especially important when it is necessary to store large volumes of food at a certain temperature or to save money electricity. Owners of equipment may be faced with a situation where they need to turn the device into a chest freezer or, conversely, use only the refrigerator compartment to keep vegetables fresh without the risk of them freezing. Understanding the operating principles of the temperature control system will allow you to effectively use the device's resources.
The deactivation process depends on the specific series and year of manufacture of your unit, since the engineering solutions of the Belarusian plant are constantly being improved. In some models, it is enough to change the settings of the electronic control unit, while in older or simpler modifications, mechanical intervention in the operation of the air dampers may be required. Important clearly identify the type of control of your equipment before starting any manipulations in order to avoid malfunction of the compressor or sensors.
In this article we will detail We will analyze the algorithms of actions for various modifications, explain the physical meaning of the processes occurring and point out critical nuances that cannot be ignored. You will learn how to correctly configure the “Solo” mode, if provided, or how to artificially limit the supply of cold to an unnecessary compartment. A competent approach will ensure long compressor life and product safety.
Principles of operation of the No Frost and static cooling system
To understand how to isolate one chamber, you must first understand the basic architecture of the refrigeration circuit. Most modern models Atlant use a single compressor that drives the refrigerant through both evaporator circuits, or a system with one evaporator in the freezer and a channel for supplying cold air to the refrigerator compartment. Temperature conditions it is regulated either by redistributing air flows through the dampers, or by changing the operating time of the compressor.
In systems No Frost cold is generated in the freezer compartment and is forced by a fan into the upper chamber through special channels. If you want to turn off the refrigerator compartment, you actually need to block these channels or trick the system into thinking that it has already reached the desired temperature. In static systems (with drip defrosting), the process is tied to natural circulation and the operation of the thermostat, which makes the task of partial shutdown more difficult without intervention in the design.
⚠️ Attention: An attempt to completely shut off the air supply channels in the systems No Frost without changing the electronics settings can lead to overheating of the motor-compressor or failure of the fan blowing.
The electronic control module receives data from temperature sensors located at different points of the unit. If you turn off the camera, but the sensor remains active and shows an increase in temperature, the compressor will work continuously, trying to cool the “void” or leaky volume. Operating algorithm The controller must be coordinated with the physical state of the cameras, otherwise an imbalance will arise, leading to increased wear and tear of the equipment.
Using Solo mode and electronic control
Many advanced refrigerator models Atlant, especially series with a digital display, have a built-in program, often called the “Solo” or “Single Chamber” mode. This mode programmatically reconfigures the operation of the unit, ignoring the readings of the sensor in the section being switched off and fixing the damper in the closed position. To activate this function, you usually need to simultaneously press certain buttons on the control panel.
To activate a special mode, find the temperature setting button or the special “Mode” button on the control panel. Often you need to hold down the combination of keys for adjusting the temperature of the refrigerator and freezer compartments for 3-5 seconds. A flashing indicator or symbol may appear on the display, indicating that one of the zones is excluded from the cooling cycle. Indication on the screen is the main signal that the system has switched to an alternative operating mode.
If your model has a “Vacation” or “Eco” function, it can also partially solve the problem by increasing the temperature in the refrigerator compartment to +10...+15°C, which actually stops active cooling, but does not freeze the food completely. However, this is not a complete shutdown, but only a transition to energy-saving mode. To completely stop the operation of one camera, the electronics must contain the appropriate program code.
Mechanical regulation and operation of dampers
In models without complex electronics, where the temperature is regulated by a mechanical thermostat, the process of turning off one chamber is physical in nature. Often in such refrigerators Atlant there is a partition with an adjustable flap between the freezer and refrigerator compartments. Turning the lever or slider allows you to completely block the flow of cold air from the freezer into the upper compartment.
With mechanical control, it is important to understand that the compressor will still be guided by the sensor located in the active zone. If you close the damper, but the thermostat is in the chamber being switched off, the compressor simply will not turn on, and the food in the work area will begin to deteriorate. Therefore, in such designs, the thermostat is always located in the chamber that is considered main (usually the freezer in two-compressor or common in simple ones).
- 🔧 Find the air damper regulator, often it is located on the back wall of the refrigerator compartment or at the top of the chamber.
- ❄️ Move the lever to the “Min” or “Closed” position to stop the flow of cold air.
- ⏱️ Make sure that the thermostat is in the active chamber, otherwise the cooling cycle will be disrupted.
In some cases, physical blocking of the damper is required if the standard mechanism does not provide a tight closure. To do this, you can use a piece of foam rubber or a plastic plug, but this must be done carefully so as not to damage the fragile plastic of the partition. Sealing The transition is critical to prevent condensation and ice formation in the unnecessary compartment.
Features of two-compressor Atlant models
The situation is radically simplified if you are the owner of a two-compressor refrigerator Atlant. In such devices, each chamber has its own independent cooling circuit, its own evaporator and its own compressor. This means that to turn off one chamber you just need to turn off the corresponding thermostat or press the shutdown button on the electronic module, if provided.
In mechanical two-compressor models, just turn the temperature control knob of the chamber being switched off to the “0” or “Off” position. The compressor of this section will stop working, while the second will function normally. This is the safest and most effective way, since the systems are completely autonomous and do not influence each other.
☑️ Checking the type of compressor
Electronic dual-compressor systems allow you to control each zone separately through a single interface. You can set the freezer temperature to -18°C and set the refrigerator compartment to Off. The electronics itself will block the operation of the corresponding compressor and fan. This is an ideal option for situations when you need to turn a refrigerator into a large freezer or vice versa.
| System type | Number of compressors | Difficulty of shutdown | Risk to food |
|---|---|---|---|
| Mechanical (1 compressor) | 1 | High (requires manipulation of the dampers) | Medium (risk of defrosting or freezing) |
| Electronic (1 compressor) | 1 | Medium (mode settings) | Low (if Solo mode is available) |
| Two-compressor | 2 | Low (independent control) | Minimum |
| No Frost (general circuit) | 1 | High (depending on electronics) | High (circulation disturbance) |
Problems and risks with incorrect shutdown
Incorrect shutdown of one of the cameras can lead to a number of technical problems. The most common of them is the “crying” of the refrigerator, when condensation begins to accumulate in a disconnected but not sealed chamber, flowing down and forming a puddle under the unit. This occurs due to temperature differences and disruption of air circulation, which is not compensated by the operating system.
Another risk is associated with the operation of the compressor. If the system “thinks” that it should cool two volumes, but physically you have closed one, excess pressure may occur in the system or, conversely, insufficient cooling of the motor if it relies on airflow from both sections. Overheating compressor windings are a serious failure that may require an expensive replacement of the unit.
⚠️ Attention: Prolonged operation of the refrigerator with the damper closed without switching to a special mode can lead to freezing of the evaporator and failure of the defrosting system.
It is also worth mentioning the risk to products. If you turn off the refrigerator compartment but do not provide sufficient insulation there, the temperature may drop below zero due to residual cold or a loose damper. Vegetables and fruits will freeze and lose their properties. Conversely, when you turn off the freezer in a single-compressor unit, food may begin to defrost faster than usual.
Why can’t you just unplug the cord of one chamber?
In two-compressor models this is possible, but in single-compressor models you will turn off the entire unit. In electronic systems, turning off the power to one zone without software support will cause a controller error (Error Code), and the refrigerator may go into protection, stopping cooling altogether.
Recommendations for use and care
If you plan to use the refrigerator in single chamber mode (for example, only as a freezer), make sure that the door seals of the disconnected section are clean and fit tightly. Otherwise, warm air will constantly penetrate inside, forcing the operating chamber to compensate for the heat gain, which will increase energy consumption. Regular checks seals are the key to effective operation.
Do not forget to defrost and clean the disconnected chamber, even if it is not working. Bacteria may multiply there or an unpleasant odor may appear, which is then difficult to remove. Wipe the internal surfaces with a weak solution of soda and leave the door slightly open for ventilation if the camera is not used for a long time.
- 🧼 Wash the disconnected camera regularly to avoid mold and odor.
- 🚪 Check the tightness of the magnetic seals on both doors cameras.
- 🌡️ Monitor the temperature in the core using an external thermometer to ensure the operation of the sensors.
Following these simple rules will allow you to flexibly manage the capabilities of your refrigerator Atlant, adapting it to current needs without the risk of breakdown. Remember that technical progress in household appliances is moving forward, and new models may have their own unique features, therefore manufacturer's instructions always remains the main document.
Is it possible to turn off the freezer compartment in the Atlant refrigerator, leaving the refrigeration compartment?
Yes, this is possible, but only if you have a two-compressor model or an electronically controlled model that supports independent settings. In simple single-compressor refrigerators, the freezer is the source of cold, and it is technically impossible to turn it off, leaving the refrigeration compartment running, without disrupting the cycle.
Why did a strong smell appear after the chamber was turned off?
Probably, there were food or moisture left in the disconnected compartment, which began to deteriorate at above-zero temperatures. The smell can also come from plastic elements if they are heated. It is necessary to thoroughly wash the chamber with a solution of vinegar or soda and dry it.
Does turning off one chamber affect energy consumption?
In two-compressor models, the consumption will decrease by almost half, since one motor does not work. In single-compressor models with the “Solo” mode, the savings will be insignificant, since the compressor continues to operate, albeit in a less loaded mode. In mechanical models with a blocked damper, consumption may even increase due to inefficient operation.
How can I understand that my Atlant model has a camera shutdown mode?
Pay attention to the control panel. If there are separate buttons for the refrigerator and freezer compartments, or a "Mode"/"F" button, the function is most likely present. In mechanical models, the presence of two separate regulators (knobs) also indicates the possibility of independent control (most often in two-compressor versions).
