How to disable the upper chamber in the Atlant refrigerator

Modern two-chamber refrigerators Atlant are reliable assistants in the kitchen, however, in certain situations, owners are faced with the need to change the standard operating mode of the unit. Most often, the question of how to turn off the upper chamber arises during the holidays, when the bulk of food is stored in the freezer, or when the upper compartment defrosting system temporarily fails. Understanding the design of your model is the first step to competent management of device resources.

It is important to immediately note that in most models Atlant there is no single “Turn off chamber” button that would completely stop the supply of cold to the refrigerator compartment, leaving the freezer operating normally. The design of these units involves the joint operation of the compressor and the refrigerant circulation system. However, there are effective ways to minimize energy consumption and actually “mothball” the upper compartment, making its use impractical.

In this article we will analyze in detail the technical nuances of the operation of evaporators, methods of temperature control and features of the operation of refrigerators with a system No Frost and drip defrosting. You will learn which controller settings allow you to achieve the minimum temperature in the upper compartment without compromising the safety of food in the freezer. Physical methods of insulating the chamber to prevent heat transfer will also be considered.

The principle of operation of the Atlant cooling system

To effectively manage temperature conditions, it is necessary to understand the basic physics of the process. In two-chamber models Atlant with one compressor, the cooling capacity is distributed between two chambers. The refrigerant, passing through condenser and the capillary tube, first enters the evaporator of the freezer compartment, and then into the evaporator of the refrigeration compartment. That is why it is technically difficult to completely stop the cooling of the upper chamber, leaving the freezer operating at full capacity, without intervention in the design.

The temperature control system is based on the readings of temperature sensors. When the temperature in the freezer reaches the set point, the thermostat or electronic controller turns off the compressor. At this moment, the upper chamber also stops cooling. However, if it is warm in the upper compartment, the compressor will turn on more often to maintain the cold below, which leads to excessive energy consumption and possible freezing of food in the freezer.

⚠️ Attention: In models with the system No Frost fans may continue to circulate air even when the compressor is stopped (in some modes), so simply closing the door is not enough - air will circulate between the compartments through the ventilation holes.

Electronic control systems installed on modern models Atlantallow you to configure parameters more flexibly, but they also have limitations. The controller operation algorithms prioritise (give priority) to the freezer compartment, since a lower temperature is required there. Understanding this priority is critical for correct settings.

Temperature adjustment via the control panel

The first and safest step to “turning off” the upper chamber is to set the maximum possible temperature in this compartment. On refrigerators Atlant with electronic control this is done through a panel on the body. Your task is to raise the temperature threshold to the maximum value at which the compressor will turn on only upon a signal from the freezer.

Usually the adjustment range in the refrigerator compartment is from +2 to +10 degrees Celsius. By setting the value to +8..+10 °C, you will create conditions close to a cool cellar. Products will not be stored in such an environment, but mold will not have time to form during a short period of inactivity. Mechanical thermostats (turns inside the chamber) also allow you to move the slider to the minimum cold zone (usually indicated by the number 1 or Min).

• 🌡️ Find the control panel on the front of the case or inside the upper chamber.
• ❄️ Press the temperature adjustment button for the refrigerator compartment (often indicated by a snowflake symbol or letter F).
• 📈 Increase the value to the maximum available limit (usually +8°C or +10°C).
• 🔒 If there is a Child Lock function, lock the panel so as not to accidentally reset the settings.

After changing the settings, the system takes time to stabilize. The compressor can operate as usual for several more hours. Do not try to abruptly change the settings back and forth, this may lead to an error in the operation of electronic module.

Using the “Vacation” mode

Many modern models Atlant are equipped with a special “Vacation” mode. This functionality is designed specifically for situations when the owners are absent for a long time and the main compartment of the refrigerator remains empty. Activating this mode automatically switches the refrigerator compartment to an economical operating mode.

In the “Vacation” mode, the temperature in the upper chamber rises to +15..+17 degrees Celsius. This prevents the appearance of unpleasant odors and mold when the door is closed, but makes it impossible to store perishable foods. At the same time, the freezer continues to operate as normal, preserving frozen stocks. This is the closest analogue of “turning off” the upper camera using standard means.

To activate the function you must:

1. Press the button Mode or a special button with a suitcase/palm tree icon.
2. Hold the button for 3-5 seconds until the corresponding indicator appears on display.
3. Make sure that the "Vacation" mode indicator lights up.

⚠️ Attention: The "Vacation" mode is not intended for storing food in the upper chamber. If you plan to leave the refrigerator on with food, this mode cannot be used - the food will spoil.

However, the physical partition between the chambers is not airtight, so some cold will still flow down if the freezer is working hard.

Physical isolation and shutting off the damper

If software the methods are not effective enough or your model Atlant does not support the “Vacation” mode, you can resort to physical isolation. In refrigerators with a No Frost system, cold air from the freezer is forced into the upper chamber through a special channel with an air damper. Blocking this channel allows you to stop the supply of cold.

The damper is usually located in the upper part of the rear wall of the refrigerator compartment or in the partition between the chambers. In some models it is controlled automatically. Covering this hole with a dense material (foam, rolled up towel) will prevent cold air from circulating. This will allow the temperature in the upper chamber to rise to room temperature while the freezer operates independently.

The table below shows the effect of various insulation methods on the temperature in the upper chamber when the freezer is running:

When using the method of blocking the air duct, it is necessary to monitor the condition of the compressor. If you have blocked the flow of cold air, and the sensors in the upper chamber (if any) continue to demand cold, the compressor may run without stopping. However, if the freezer has priority, it will quickly reach its temperature and turn off the unit.

How to find the air duct?

In most Atlant No Frost models, the air duct is located in the upper part of the rear wall of the refrigerator compartment, hidden by a plastic grille. Remove the shelves and look up.

Energy saving during partial operation

Partial operation of the refrigerator, when only the freezer is used, does not always lead to significant energy savings. The compressor still has to cool the volume of the freezer, and heat loss through the walls of the overall structure does not disappear. Moreover, if the upper chamber is warm and the freezer is cold, a temperature difference occurs that increases heat inflow.

To minimize energy costs in this mode, it is recommended:

• 📦 Fill the freezer compartment as much as possible with food or bags of water (ice accumulates cold).
• 🚪 Check the tightness of the seals of both doors.
• 🧊 Do not open the upper chamber again, so as not to heat its contents (air).
• 🧹 Ensure good ventilation of the condenser at the back of the refrigerator.

Modern inverter compressors installed on top models Atlantcope more effectively with maintaining the temperature in one chamber, smoothly regulating power. Older models with conventional compressors will operate in jerks, which is less economical.

⚠️ Attention: If you leave the refrigerator operating in this mode for more than a month, be sure to check the condition of the rubber seals on the top door once every two weeks. The lack of cold can lead to their drying out faster than usual.

It is also worth considering that when only the freezer is used for a long time, condensation may accumulate in the system in places where it was previously dry. This can lead to corrosion of internal elements or the appearance of moisture in the insulation.

Frequent errors and precautions

When trying to turn off the upper chamber, users often make mistakes that can lead to equipment breakdown. One of the most common is an attempt to seal temperature sensors or jam thermostat reeds with foreign objects. This leads to incorrect operation of the automation and possible failure compressor due to operation in abnormal mode.

Another mistake is complete ignoring of the upper chamber. If you don't use it for months, it can develop mold or insects that will then move into the seals and other parts of the refrigerator. Periodic maintenance is necessary even for “disabled” compartments.

Basic prohibitions when manipulating cameras:

1. Do not cut the wires leading to the light bulb or the sensor of the upper chamber.
2. Do not seal the ventilation holes tightly with foam or sealant.
3. Do not use heating devices inside the chamber to “defrost” before turning it off.

If you notice that after setting the “Vacation” mode or increasing the temperature in the upper chamber, the ice in the freezer has stopped freezing or the food has begun to thaw, immediately return the settings to the factory settings. This means that your model does not structurally support long-term operation with a warm upper chamber.

FAQ: Frequently Asked Questions

Is it possible to completely turn off the freon supply to the upper chamber?

Technically, in household refrigerators Atlant there is no separate valve for shutting off the freon pipe to the refrigeration compartment. The system is one. Stopping the circulation is only possible when the compressor is stopped, which will also freeze the freezer. Therefore, methods are used to increase the temperature or block air flows.

Will there be savings in electricity if the upper chamber is warm?

There will be savings, but not 50%, as many people think. The compressor still works to cool the freezer. The savings will be about 20-30% due to the absence of heat inflows from opening the upper door and loading warm products, but the basic consumption to maintain frost will remain.

What to do if in the “Vacation” mode it is still cold in the upper chamber?

This is normal for some models where the air channels are wide open. Try to physically limit the circulation by placing bulky objects (boxes) in the upper chamber that will block the air movement, or carefully cover the ventilation hole with a cloth.

Is it harmful for the compressor to work only on the freezer?

For a short time - no. Long-term operation (for months) in a mode where one chamber is warm and the other cold creates an uneven thermal load on the housing and can increase the frequency of compressor switching on, which reduces its service life. It is better to defrost the refrigerator completely if it is not in use.
