Modern two-chamber refrigerators, especially models from the Belarusian manufacturer Atlant, are often equipped with two independent compressors, which allows you to regulate the temperature in the refrigerator and freezer compartments separately from each other. Such a cooling system No Frost or a drip system in different chambers gives the user flexibility in controlling the climate inside the device. However, there are situations when it is necessary to completely turn off one of the chambers, for example, to save energy or when there is a temporary lack of demand for freezing food.
Many owners are wondering whether it is possible to simply turn off the freezer, leaving the main department working, and how to do this correctly without damaging the equipment. Unlike old single-compressor models, where turning off one zone was impossible without stopping the entire unit, equipment Atlant with two motor-compressors structurally allows you to isolate the operation of the freezer. It is important to understand the difference between putting the camera into standby mode (minimum load) and completely physically turning off the power to the unit.
In this article we will analyze in detail the technical aspects of operating such refrigerators, consider standard adjustment methods and non-standard solutions. You will learn what temperature modes are available, how to interpret the readings of thermostats, and what absolutely cannot be done with the electronics or mechanical relays of your device. Complete physical shutdown of the freezer compressor is only possible by disconnecting the power wires or using an external socket with a timer, since there is usually no standard “On/Off” switch for a separate compressor on the case.
The principle of operation of a two-compressor system
Refrigerators Atlantequipped with two compressors are actually two independent refrigeration units in one housing. Each compressor is responsible for its own cooling circuit: one serves the refrigeration chamber, the second serves the freezer. This means that the breakdown or shutdown of one motor does not affect the performance of the other, which is the main advantage of such a scheme.
Temperature control is carried out independently. The refrigerator compartment is usually equipped with a mechanical or electronic thermostat that controls the temperature in the range from +2 to +10 degrees Celsius. The freezer compartment has its own regulator, which allows you to change the mode from minimal cooling to the fast freezing mode. Independence of the circuits allows you to theoretically stop the cooling cycle in the freezer if you stop supplying voltage to it or set the regulator to the extreme position.
However, it is worth taking into account the characteristics of the refrigerant and oil. Compressors are designed for intermittent operation. If you simply leave the freezer turned off for a long time, the oil in the crankcase may thicken or mix with the refrigerant, which, upon subsequent startup, will lead to water hammer or increased wear of rubbing parts. Therefore, long-term idle time of one of the circuits requires compliance with certain operating rules.
⚠️ Attention: Do not try to forcibly block the thermostat contacts in the “off” position using foreign objects. This can lead to a short circuit in the control circuit or melting of the plastic elements of the panel.
Standard shutdown methods via a thermostat
The safest way to minimize the operation of the freezer, provided by the manufacturer, is to use a standard thermostat. In models Atlant with mechanical control, the regulator is a rotary knob with divisions from 0 to 7 (or from Min to Max). Position “0” or “Off” means the electrical circuit of the thermostat is opened.
When the knob is moved to position "0", the freezer compressor stops receiving the start signal. The engine does not turn on, and the temperature inside the chamber begins to gradually rise to room temperature. In fact, this is a regular shutdown. If your goal is to simply stop freezing food, but keep the cold in the main compartment, this action is enough.
In electronic models, control is carried out via the display. Here you need to find the freezer temperature setting menu and set the maximum possible value (usually -6 or -8 degrees, or the “Vacation” mode if it is implemented in software for one chamber). However, the “Vacation” mode more often turns off the refrigerator compartment, not the freezer, so carefully study the instructions for the specific model.
- ❄️ Turn the freezer thermostat knob counterclockwise until it clicks or stops.
- 🔌 Make sure that the compressor operation indicator (if any) goes off, indicating stop.
- 🌡️ Control the temperature inside the chamber to avoid the appearance of an unpleasant odor or mold.
It is important to understand that even when turned off, heat exchange will occur through the partition between the chambers. The cold from the operating refrigerator compartment can partially penetrate into the freezer, maintaining the temperature there slightly below room temperature, but not sufficient for storing frozen food. Thermal insulation of the partition in two-chamber models it is usually high, but not absolute.
Physically turning off the compressor: technical nuances
If there is no standard switch, or the thermostat is faulty and does not open the circuit in position “0”, users are considering the option of physically turning off the compressor. In two-compressor Atlantakh each motor has its own start-up protection equipment and is independently connected to the network. Theoretically, it is possible to break the power circuit of a specific compressor.
To do this, you will need access to the electrical circuit of the refrigerator, which is usually located in the lower rear part of the case or under the plastic cover on the rear wall. Electrical diagram a two-compressor refrigerator is more complicated than a single-compressor one, but the principle remains the same: phase and zero goes to the start relay and motor windings. Disconnecting wires requires electrical skills and compliance with safety precautions.
There is a simpler, but less aesthetic method - using an intermediate socket with a timer or a separate switch installed in the break of the power cord (if the design provides for a removable cable, which is rare for refrigerators) or in the break of the internal wiring. However, installing an external switch on the housing or inside the cabinet requires professional intervention so as not to compromise the tightness and fire safety.
| Disconnection method | Complexity | Risks | Recommended period |
|---|---|---|---|
| Thermoregulator (position 0) | Low | Minimum | Up to 1 month |
| External timer-socket | Low | Medium (heating of contacts) | Short-term |
| Open circuit inside the case | High | High (warranty, safety) | Permanently |
| Disconnecting the relay manually | Average | Damage to the relay | Emergency |
⚠️ Attention: Any interference with the electrical circuit of the refrigerator (opening the case, cutting wires) will void the manufacturer's warranty. If the refrigerator is under warranty service, use only standard controls.
☑️ Check before physical disconnection
Using the “Vacation” mode and its limitations
Many modern models Atlant are equipped with the “Vacation Mode” function. Users often mistakenly believe that this mode turns off the freezer, leaving the refrigerator compartment to work. In fact, the logic of this mode is most often the opposite or specific.
In the classical sense, the “Vacation” mode is intended for long-term preservation of the refrigerator, when it remains turned on but is not used. In this mode, usually the refrigerator compartment is turned off (to prevent food from becoming moldy and not wasting energy), and the freezer continues to operate normally. This allows you to preserve frozen supplies and prevent the appearance of odor in the empty main compartment.
However, in some electronic models with advanced functionality, the algorithm may be reprogrammed or have variations. There are modifications where “Vacation” switches both circuits to an energy-saving mode, or allows you to choose which camera to leave active. To find out exactly how your Atlantbehaves, you need to refer to the product data sheet.
If your goal is to turn off the freezer, the “Vacation” mode most likely will not suit you, since it is designed to maintain freezing while minimizing the operation of the main compartment. Trying to use this mode for the opposite effect may result in defrosting food in the main chamber while the freezer continues to consume electricity.
Why can’t you keep the refrigerator empty for a long time?
An empty refrigerator works less efficiently. The thermal inertia of food helps stabilize the temperature. If the chambers are empty, the compressor may turn on more often for short periods of time, which is harmful to the engine. It is recommended to fill the free space with bottles of water.
The consequences of long-term downtime of the freezer
When deciding to turn off the freezer, it is important to be aware of the consequences for the equipment. A compressor that doesn't start for months is at risk. Oil circulates in the system, which lubricates the rubbing parts. During prolonged idle time, the oil drains into the crankcase, and condensation may form in the pipelines if the seal is broken or there are microcracks.
In addition, in the warm and humid environment of a stopped freezer (especially if there is moisture left in it from a previous defrost), bacteria and mold fungi actively multiply. Rubber door seals without cold can quickly lose elasticity or, conversely, “stick” to the body if you do not wipe them periodically. Rubber seal requires care even when the chamber is not used for its intended purpose.
If you plan to turn off the freezer for a period of more than two weeks, it is recommended:
- 🧹 Wash thoroughly and, most importantly, dry the chamber before turning it off.
- 🚪 Leave the freezer door slightly open for ventilation (use a limiter).
- 🧴 Wipe the seals with glycerin or a special care product rubber.
Ignoring these rules will lead to the fact that when you turn it on again you will be greeted by a persistent musty smell, which is difficult to get rid of. In some cases, replacement of seals or professional cleaning with ozonation may be necessary.
Common problems and their solutions
When operating a two-chamber refrigerator Atlanta with a partially turned off freezer, users may encounter a number of problems. One of them is ice freezing at the boundaries of the chambers or in the air flow channel (if the model allows partial heat exchange). This is due to differences in temperature and humidity.
Another problem is noise. A running refrigerator compressor can create vibration that is transmitted to the body of a stopped freezer, causing resonance. If the freezer is empty, it acts as a resonator, increasing the hum. A solution could be to densely fill the chamber with food or containers of water, which will improve the acoustics.
An electronics malfunction is also possible. On electronically controlled models, turning off one of the circuits through the menu may be perceived by the system as a temperature sensor error if the actual temperature does not reach the set values within a reasonable time. In this case, a malfunction indicator may light up on the display.
⚠️ Attention: Technical characteristics and operating algorithms may vary depending on the year of manufacture and the specific series of the refrigerator. Always check the official documentation for your model, as manufacturers can change the operating logic of the controllers.
FAQ: Frequently asked questions
Is it possible to completely remove the freezer from the Atlant refrigerator?
Structurally dismantle the freezer (remove the drawers, remove evaporator) is possible, but this makes no sense, since it is part of the housing. However, you can completely stop using its functionality by turning off the compressor, and use the volume as a closet or pantry, having previously provided ventilation.
Will electricity be saved if you turn off one compressor?
Yes, the savings will be significant. Two-compressor refrigerators consume energy independently for each chamber. By turning off the freezer, you will reduce the total energy consumption by almost 40-50%, since the freezer requires more intensive work to maintain low temperatures.
What to do if after turning on the freezer does not work?
If after a long period of inactivity and turning the regulator to the operating position, the compressor does not start within 15-20 minutes, it may have worked thermal protection relay or electronics failure. Try turning off the power to the refrigerator completely for 10-15 minutes, then turning it on again. If the startup sound does not appear, diagnostics by a technician is required.
Is rare startup (once a week) harmful for the compressor?
Rare startup is worse than constant operation or complete shutdown. During rare starts, the oil does not have time to be evenly distributed throughout the system, and condensate that gets into the oil during idle time can cause corrosion of internal parts. For such modes, it is better to use timers with more frequent cycles or keep the camera turned off constantly.
