Situations when it is required temporarily or permanently turn off the freezer in a two-chamber refrigerator do not arise very rarely for owners of household appliances. Most often this is due to the need to defrost, clean, or the desire to convert equipment to store only chilled products in the summer. Refrigerators Atlant are one of the most popular models in the post-Soviet space, and their design allows flexible control of temperature conditions.
However, before proceeding with manipulations, it is important to understand that the principle of operation of the unit depends on the type of cooling system. In models with the system No Frost and in classic versions with drop defrosting action algorithms may differ significantly. Improper shutdown can lead to damage to the compressor or disruption of refrigerant circulation.
In this article we will analyze in detail the technical nuances, consider software settings and physical methods for limiting the operation of the freezer compartment. You will learn how to safely switch the refrigerator to the “refrigerator only” mode and what restrictions are imposed by the design of your model Atlant.
Design features of two-chamber Atlant models
Two-chamber refrigerators Atlant are structurally divided into two independent compartments, but often have one common compressor This means that the refrigerant circulates in a single circuit, passing first through the freezer compartment and then through the refrigerator compartment. That is why it is physically impossible to simply “turn off” the freezer with a button in older models without disrupting the operation of the entire system.
Modern series, such as XM 4000 or XM 6000, are equipped with more complex electronics. Here, the cold flow is controlled by means of electromagnetic valves and dampers. If your model supports the “Vacation” function or has independent cooling circuits, the problem is solved in software. Otherwise, you will have to resort to mechanical methods.
⚠️ Attention: In models with one compressor and one freon circulation circuit, a complete stop of the freezer compartment while the refrigerator is running is impossible without the risk of compressor failure due to lack of oil return or overheating.
The key element is the thermostat or electronic control unit. In mechanical models, turning the thermostat knob to the “0” or “Off” position stops the operation of the entire unit. To implement the task, we need models with the possibility of separate adjustment or specific engineering modes.
Software shutdown via the control panel
If your Atlant is equipped with an electronic display and control panel, you have a high chance of solving the problem without interfering with the insides of the unit. Many modern models support Vacation mode. When this mode is activated, the refrigerator compartment goes into economy mode (usually +15°C), and the freezer continues to operate. But we need the opposite.
In some advanced models with a system Full No Frost and two fans, individual settings are possible. To do this, you need to enter the settings menu. Typically, the sequence of actions looks like this: hold down the “Mode” or “Freezer” button for 3-5 seconds until the indicators blink.
- 🔹 Press the freezer temperature adjustment button.
- 🔹 Reduce the value until the “--” or “OFF” symbol appears.
- 🔹 Confirm the action with the “OK” button or wait for automatic saving.
- 🔹 Make sure that the compressor operation indicator has gone out or changed its flashing mode.
It is important to note that even with a program shutdown, the temperature in the freezer will slowly rise, since the cold is partially transferred through the partition from the operating refrigeration compartment. It will not become completely “warm” if you do not defrost it manually.
Mechanical ways to limit freezer operation
For owners of classic models Atlant with mechanical control and one thermostat, the situation is more complicated. There are no electronics here that could shut off the supply of freon to one of the circuits. The only physical way is to block the access of cold air or stop the circulation.
In models with a system Low Frost or an improved drip system, sometimes you can manually close the damper through which cold air from the freezer enters the refrigerator compartment. However, this will not turn off the freezer itself, but will only isolate its air flow. The freezer will continue to freeze, consuming electricity.
There is a radical method that experts sometimes use, but it requires caution. This is the installation of an additional thermostat in the compressor power circuit, which will turn off the refrigerator when a certain temperature in the freezer is reached, but this will turn your two-chamber refrigerator into a single-chamber refrigerator with a non-working upper (or lower) part.
⚠️ Attention: Independent intervention in the electrical circuit of the refrigerator (inserting thermostats, reconnecting wires) will void the warranty and can lead to a fire hazard if the calculation is incorrect. loads.
The safest “mechanical” method for older models is to use dense thermal insulation of the entrance to the freezer and set the minimum compressor power through the thermostat, but this will require constant monitoring of temperatures.
Using the “Vacation” mode and its limitations
Many users confuse the modes, believing that “Vacation” turns off the freezer. In fact, in most refrigerators Atlant this mode is designed for the opposite purpose: it turns off the refrigerator compartment to prevent mold and odors while you are not at home, but keeps the freezer operating for storing frozen food.
However, in some new series with two compressors (for example, some models of the XM 7000series) independent operation of the circuits is possible. If you have just such a model, then turning off one of the circuits occurs normally through the control panel. You can find out the type of compressor in the technical data sheet or by the markings on the nameplate.
| System type | Ability to turn off the freezer | Method | Risks |
|---|---|---|---|
| One compressor, drip | Not possible normally | Only complete defrosting | High (compressor damage) |
| One compressor, No Frost | Partially (software) | Menu settings (if any) | Medium (imbalance) |
| Two compressors | Full | Separate thermostat | Low |
| Full No Frost system | Depends on the model | Electronic control | Medium |
Using the wrong mode may cause food in the refrigerator compartment to spoil and the freezer to continue to consume energy. Always check the instructions for the specific model Atlant.
What happens to freon when one chamber is turned off?
In systems with one circuit, freon continues to circulate throughout the circle. If you artificially block the path of cold into one chamber, the pressure in the system may increase, which will lead to emergency operation of the valves or stopping the compressor by the protection.
Step-by-step instructions for safe defrosting
If your goal is to temporarily free up the freezer for storing a large volume of food or for washing, it is better to do a complete defrosting rather than try to “deceive” the equipment. This is a standard procedure provided by the manufacturer.
First, you need to disconnect the refrigerator from the power supply. Remove all food from the freezer and refrigerator. If you want to use the refrigerator compartment while the freezer is defrosting, this is possible, but the temperature in it will be higher than normal.
☑️ Safe defrosting algorithm
Open the freezer door. Leave it open until the ice has completely melted. Speed up the process with a knife or hairdryer strictly prohibitedas the evaporator can be damaged. After the ice has melted, wipe the chamber dry.
If you need the freezer not to freeze while the refrigerator is running (for example, to store vegetables), simply do not turn on the freezer after defrosting. However, in models with one thermostat, this will cause the refrigerator compartment to stop cooling. In two-compressor models, you can simply not turn on the upper chamber.
Common mistakes and precautions
When trying to turn off the freezer, users often make mistakes that lead to expensive repairs. The most common mistake is trying to seal the temperature sensor in the freezer with tape or tape in order to “fool” the thermostat.
This leads to the compressor running continuously, trying to cool the “blocked” sensor. As a result, the overheating of the windings engine occurs and fails. It is also possible that the condensate drainage channels in No Frost systems may freeze.
⚠️ Attention: Never seal temperature sensors or block the ventilation holes between the chambers with foreign objects (foam, cloth) on a permanent basis. This disrupts heat transfer and can cause a fire in the wiring.
Another mistake is using external timer sockets to cycle the refrigerator on and off in order to regulate the temperature in the freezer. This is detrimental to the compressor, which is not designed for frequent starts and stops.
Alternative storage solutions products
If the standard capabilities of your Atlanta do not allow flexible control of the freezer, and the need for large refrigeration space is great, it is worth considering alternatives. For example, using a freezer only in winter on the balcony (if the model allows operation at low temperatures).
You can also use special thermal containers with refrigerants inside a working refrigerator to simulate freezing for small volumes. But this is not suitable for a complete replacement of functionality.
In conclusion, remember that a two-chamber refrigerator is a complex unit. Its repurposing must be carried out taking into account technical limitations. If the model does not provide for turning off the freezer, it is better not to risk the resource of the equipment.
FAQ: Frequently asked questions
Is it possible to permanently turn off a freezer in Atlanta with one compressor?
No using standard means. You can just not use it, leaving the door ajar (with a lock so it doesn’t slam) for ventilation, but there will still be cold there.
Why did the refrigerator become warmer after turning off the freezer?
In systems with one circuit, the cold is generated in the freezer and then transferred to the refrigerator compartment. If there is no cold in the freezer, there is no cold in the main compartment.
Is it harmful for the compressor to keep the thermostat at a minimum?
Yes, this forces the compressor to work at the limit, shortening its service life. It is better to set the average values and monitor the temperature with a thermometer.
How can I find out how many compressors are in my Atlanta?
Look at the back wall: if there are two motors (usually different sizes or the same), then there are two. There is also information in the technical data sheet in the “Characteristics” section.
