Refrigeration equipment brand Atlant deservedly popular due to its reliability and maintainability. Owners of models with two compressors often wonder whether it is possible to save energy by turning off one of the chambers, for example, a freezer, when it is not needed. This situation may arise when residents are away from home for a long time or when only fresh food is temporarily stored. The answer lies in the design features of the temperature control system.
The main advantage of two-compressor systems is the complete autonomy of the cooling circuits. This means that you can physically turn off the power to the freezer compressor while leaving the refrigerator compartment running as normal. It is important to understand that simply closing the door is not enough - the unit will continue to consume energy, trying to maintain the set temperature. The correct sequence of actions will avoid breakdowns and extend the life of the equipment.
Before you begin any manipulations, you need to understand the type of control of your model. Modern and some older models Atlant can use different control systems: mechanical thermostats or electronic control units. The shutdown method directly depends on this. Incorrect actions can lead to defrosting of food in the refrigerator compartment or failure of the start relay.
The principle of operation of the Atlant two-compressor system
Two-chamber refrigerators Atlant are designed with two compressors so that each chamber has its own independent refrigerant circuit and its own compressor motor. One compressor is responsible for creating cold in the refrigerator compartment, and the second in the freezer. This technical solution allows you to set different temperature conditions independently of each other. It is this independence that makes it possible to turn off one of the chambers without disrupting the operation of the second.
When you turn off the freezer, you interrupt the power supply circuit to its compressor. At this moment, the evaporator of the freezer stops cooling, and the temperature inside it begins to rise to room temperature. At the same time, the refrigerator compartment compressor continues to operate, maintaining cold in the main chamber. This scheme is effective for saving energy if the freezer is empty or is used to store products that do not require deep freezing.
It is worth noting that in some models with the system No Frost there may be nuances with air circulation, although in classic two-compressor models Atlant a drip defrosting system is more common. If your model provides forced air circulation between the chambers (which is rare for two compressors, but possible in some series), then turning off one circuit may upset the temperature balance. In classic models with evaporators behind the rear wall, this problem does not arise.
⚠️ Attention: Before turning off the compressor, make sure that there are no products in the freezer that require storage at temperatures below -18°C. A prolonged increase in temperature will lead to spoilage of frozen goods and the growth of bacteria.
Understanding the operating principle helps to avoid common mistakes. Many users try to simply set the regulator to minimum, but this does not turn off the compressor completely, but only makes it turn on less often. To completely stop, it is necessary to break the electrical control circuit of a specific unit. This ensures that the engine will not start accidentally due to an electronic failure or stuck contacts.
Determining the type of refrigerator control
The first step in the shutdown process is to accurately determine the type of control system for your refrigerator Atlant. The set of actions that you have to perform depends on this. Models can be equipped with mechanical thermostats, electronic controls with a display, or a combined system. An error in determining the type can lead to attempts to turn non-existent knobs or look for buttons where there are none.
Mechanical control is characterized by the presence of rotary controls inside the refrigeration chamber or on the case. Usually these are round knobs with numbers from 1 to 7 or from Min to Max. In dual-compressor models, there may be two such handles: one for the refrigerator compartment, the other for the freezer. Electronic control implies the presence of a display on the outer door and touch buttons for setting modes.
To accurately identify the model and type of control, refer to the technical data sheet of the device or look for a label with markings. It is located inside the chamber or on the rear wall of the unit. Knowing the exact model, for example Atlant XM-4425 or XM-6025, you can find the specification on the Internet. Below is a table that helps classify the main types of control.
| Type of control | Location of regulators | Signs of the presence of two compressors | Method shutdown |
|---|---|---|---|
| Mechanical | Inside the chambers (handles) | Two temperature controllers | Rotate the handle to the "0" or "Off" position |
| Electronic | Display on the door | Separate indicators for each camera | Through the settings menu or the "Disable" button |
| Combined | Handle + Display | One compressor with valve (rarely) | Depends on the specific configuration |
| Mechanical (old) | External or internal | Lack of electronics | Physical disconnection from the network or thermostat |
If you find that your model has only one thermostat, but two compressors (which happens in very old or specific industrial models), then the control can be centralized. However, household refrigerators Atlant are characterized by the following scheme: one thermostat per compressor. Carefully inspect the interior of the refrigerator compartment: usually the freezer thermostat is located in the same place as the refrigerator regulator, or is placed on the front panel if the model allows external control.
Instructions for turning off using a mechanical thermostat
The most common way to turn off the freezer compartment in refrigerators Atlant is using a mechanical thermostat. This method is applicable for models where control is carried out by rotary knobs. The process is simple, but requires consistency so as not to disrupt the operation of the main cooling circuit. The main thing is to find the right regulator that is responsible specifically for the freezer.
Usually the regulators are labeled or color-coded. If there are no labels, focus on the location: the freezer regulator is often located next to the refrigerator regulator, but can be moved to the side. On the thermostat scale, look for the position indicated by the number 0 or the word Off (Off). Turning the knob to this position opens the electrical contacts and the compressor stops receiving power.
Follow these steps to safely shut down:
- 🔌 Locate the freezer thermostat (often located inside the refrigerator compartment on the top wall or side panel).
- 🔄 Smooth turn the knob counterclockwise all the way to the position
0orOff. - 👂 Listen: after a few minutes the freezer compressor should stop, if it was running at that moment.
- ❄️ Make sure that the refrigerator compartment continues to operate (check the presence of cold or the operation of the main compressor).
Some models of mechanical thermostats do not have an explicit “Off” position. In this case, you need to turn the knob to the minimum value (usually a number 1). This will not turn off the compressor completely, but will cause it to operate minimally, which will gradually defrost the chamber. To completely turn off in such cases, it may be necessary to physically disconnect the device from the outlet, but then the refrigerator compartment will also stop working if they are not completely separated by power (which is rare for household models; usually they are in the same case, but on different circuits).
⚠️ Attention: Do not use excessive force when turning the thermostat knobs. The mechanism is plastic and can break when jerked, which will require replacing the entire thermostat.
☑️ Checking the freezer shutdown
Setting up the electronic control and display
Modern models Atlant often equipped with an electronic control unit with a digital display. This provides more flexible setup options, including Vacation modes or individually turning off cameras. The interface may differ depending on the series of the refrigerator, but the logic of actions remains similar. You will need to interact with the touch buttons on the outer panel of the door.
To turn off the freezer via the electronic unit, find the button responsible for setting the freezer temperature. It is often indicated by a snowflake symbol or an inscription Freezer. By pressing the temperature adjustment button, bring the value to the minimum possible or to the symbol indicating shutdown (for example, a dash - or inscription Off). Some models require a long press of the button (3-5 seconds) to activate the shutdown mode.
If your model has a "Vacation" (Vacation) mode, it can automatically turn off the freezer or put the refrigerator in economy mode. However, be careful: in some implementations, this mode, on the contrary, turns off the refrigerator compartment, leaving the freezer running. Read the symbols on the display carefully. Electronics Atlant often uses flashing indicators to signal the transition to a new mode.
Sequence of actions for electronic models:
- 🖱️ Press the camera selection button (symbol of a refrigerator or freezer) until the setting of the desired compartment is activated.
- 📉 Use the temperature adjustment buttons to change the value on the display.
- ⏸️ Bring the freezer indicator to the off value (usually
Off). - ✅ Confirm the selection if the system requires confirmation (sometimes you just need to stop pressing the buttons and wait 10 seconds).
What to do if the display does not respond?
If the touch buttons do not respond to pressing, the control panel may be locked. Find the button with the image of a lock and hold it for 3-5 seconds until a beep sounds or the characters on the screen unlock.
Physically turning off the compressor and safety measures
In cases where it is impossible to turn off the freezer using standard means (for example, the thermostat is faulty or the design does not provide such a function), you can resort to physically turning off the compressor. This method requires basic skills in working with electrical equipment and observing safety measures. Remember that any intervention in the electrical part of the device can affect it. guarantee.
First, you need to completely disconnect the refrigerator by removing the plug from the socket. Then remove the rear protective panel at the bottom of the unit, where the compressor compartment is located. In two-compressor models, you will see two compressor motors. They are usually labeled or differ in the location of the pipelines. The freezer compressor is usually more powerful and connected to thicker tubes. freezer.
Physical shutdown process:
- 🔌 Disconnect the refrigerator from the power supply (unplug the plug).
- 🔧 Remove the back metal cover covering the compressors.
- 🔍 Identify the freezer compressor (usually it is the top one or has a marking).
- ✂️ Disconnect the power wires from the start relay or terminal block of the specific compressor (after taking a photo of the connection diagram!).
⚠️ Attention: Physical turning off the compressor should only be done by a qualified specialist. Incorrect connection of the wires can lead to a short circuit, fire or failure of the second compressor. Insulate the disconnected ends of the wires with electrical tape.
If you are not confident in your abilities, it is better not to risk installing a separate timer socket on the power supply line of the freezer, if it is possible to separate the power supply of the circuits. (requires intervention in the wiring inside the case). However, for most users, standard means of adjustment are sufficient. After physically disconnecting, be sure to check the operation of the remaining compressor by turning on the refrigerator.
Features of operation in single camera mode
Operating a two-compartment refrigerator Atlant with the freezer turned off has its own characteristics. First of all, this concerns the temperature regime in the main chamber. Since heat exchange between the chambers still occurs (through the partition), the lack of cold from the freezer may slightly affect the operation of the refrigeration compartment, although the two-compressor system should compensate for this. automatically.
It is important to monitor the formation of condensation. If the freezer is defrosting, water may appear inside it. Make sure that the melt water drain system (if it is designed for the defrosting mode) is not clogged. Under normal conditions, water evaporates, but when a large volume of ice is completely defrosted, there may be too much of it. It is recommended to put absorbent materials in the chamber or periodically wipe it.
It is also worth considering the load on the running compressor. If you leave the refrigerator in single chamber mode for a long time (for example, during a vacation), make sure that the door seals are working properly. Heat from the warm freezer (which has become just a cabinet) can penetrate into the refrigerator compartment, causing the running compressor to turn on more often. energy consumption, although less than when operating two compressors.
Recommendations for care in this mode:
- 🧼 Regularly ventilate the disconnected freezer, leaving the door ajar to prevent the appearance of mold and odors.
- 🌡️ Monitor the temperature in the refrigerator compartment; you may need to slightly reduce the power of the main thermostat.
- 🔌 For long periods of inactivity (more than a month), it is recommended to completely defrost and wash both chambers, leaving the doors open.
Is it possible to turn off the freezer if Is there food left in it?
You can turn off the freezer with food inside only for a short time (for example, to defrost ice), if the food is not temperature critical. If you plan to turn off the camera for days or weeks, the food must be transferred to another freezer or consumed. When the temperature rises above -6°C, active growth of bacteria begins, and the food spoils, even if it looks normal on the outside.
Why, after turning on, does the freezer not reach the temperature for a long time?
After a long period of inactivity or complete defrosting, the compressor takes time (from 2 to 12 hours) to freeze the chamber to operating values. During this time, do not load the chamber with food, let the system return to mode. If the temperature does not drop for more than 12 hours, there may be a freon leak or a fault. compressor.
Does the shutdown of one chamber affect the service life of the second?
No, the operation of compressors in dual-circuit systems Atlant disconnection of one unit does not create additional load on the second, on the contrary, the total resource of the equipment in this mode is consumed more slowly, since one of the engines is resting. ventilation around the operating compressor.
What does the flashing indicator mean after shutdown?
A flashing temperature or alarm indicator on the display means that the actual temperature in the chamber is higher than the set one. This is normal immediately after turning off or loading warm products. If the indicator does not stop flashing after entering the mode, check the density. the fit of the door and the operation of the thermostat.
Do you need to defrost the freezer before turning it off?
If you turn off the camera for a short time (several hours), defrosting is not necessary. If the camera will be turned off for several days or weeks, it is recommended to first defrost it and wipe it dry, the remaining ice will melt, and the water may melt. leak onto the floor or cause corrosion of internal elements.
