How to adjust the Atlant two-chamber refrigerator: a complete guide

Two-chamber refrigerators of the Belarusian brand Atlant have earned a reputation as reliable and durable equipment, however, even the highest quality unit requires periodic adjustments. Incorrect adjustment often leads to food in the freezer freezing too much, and in the refrigerator compartment, on the contrary, spoiling due to lack of cold. Owners are often faced with a situation where the equipment operates in increased mode, consuming excess electricity, or makes extraneous sounds.

Independent adjusting the Atlant refrigerator is a process that does not require calling a specialist in 90% of cases and can be completed by one person in 15-20 minutes. It is important to understand that most models are equipped with mechanical or electronic control systems, each of which has its own configuration nuances. Ignoring these features can lead to rapid failure of the compressor or the formation of an ice coat.

In this article we will analyze all aspects of adjustment: from rotating the thermostat knob to adjusting the position of the doors and dampers. You will learn how to correctly set the temperature for various operating conditions and what to do if the standard settings no longer cope with their task. A competent approach will extend the life of your device.

⚠️ Attention: Before starting any adjustment work, be sure to disconnect the refrigerator from the power supply. Working with electrical components or mechanical adjustment of live components can be life-threatening and damage the electronics of the device.

The principle of operation of the thermostat in different models

The main element responsible for maintaining the microclimate inside the chambers is the thermostat. In models Atlant with mechanical control, it is a handle, usually located on the top panel or inside the refrigerator compartment. Turning this knob changes the tension of the bellows, which, in turn, opens or closes the contacts, starting the compressor. Temperature mode directly depends on the position of this knob.

Electronic systems controls found in more modern series use temperature sensors and a digital display. Here the adjustment occurs by changing the settings on the controller. Unlike mechanics, where you specify an approximate “degree of cold,” in electronics you operate with specific degrees Celsius. This allows you to achieve greater accuracy, but requires an understanding of the logic of the digital control unit.

It must be taken into account that a mechanical thermostat has a range of values, often designated by numbers from 1 to 7 or Min/Max. Accordingly, the number “7” or “Max” is the maximum freezing mode, in which the compressor operates almost without interruption.

⚠️ Attention: The design of thermostats may differ depending on the year of manufacture of the model. If you cannot find the adjustment knob, check the official instructions for your specific modification, as the location of the control may vary.

Understanding how it works thermostat is critical to proper operation. If you turn the knob to maximum in the summer in a hot kitchen, the compressor will work hard, trying to compensate for heat inflows from the outside. This is a direct path to overheating and breakdown.

⚠️ Attention: Do not try to disassemble the thermostat itself or change its settings inside the case without special knowledge. Only the external handle or interface buttons can be adjusted.

Setting the temperature mode and freezing power

Correct temperature setting is the key to food safety. For the refrigerator compartment, the optimal range is considered to be from +3 to +5 degrees Celsius. In the freezer, the temperature should be maintained at -18 degrees or lower. In mechanical models Atlant this corresponds to the middle position of the regulator, usually numbers 3 or 4.

If you notice that ice is forming in the refrigerator compartment on the back wall, and the food near the door is melting, it means that the operating mode is selected incorrectly or the air circulation is impaired. In this case, it is necessary to shift the regulator towards lower values ​​(towards number 1 or Min). Conversely, if the ice cream has become soft and the meat is not frosted deeply enough, add power by turning the knob towards larger numbers.

Particular attention should be paid to the Super Freeze function, if it is provided in your model. This mode forces the compressor to run without stopping to quickly freeze fresh food. You cannot use it constantly - this will lead to freezing of the evaporator and increased energy consumption. After freezing a fresh batch of food, the function must be turned off manually or wait for automatic shutdown after 24-48 hours.

To accurately diagnose the current condition, it is recommended to use an external thermometer. Place it in a glass of water on the middle shelf of the refrigerator and leave it for several hours. This is the only way to understand the real temperature, since the built-in indicators (if any) often show only approximate values or the operating status of the compressor.

Adjusting the position of the doors and damper

One of the common causes of temperature violations is loose fitting of the doors. If the sealing rubber does not provide a tight seal, warm, moist air constantly enters the chamber. This leads to the formation of a “fur coat” on the evaporator and increased frequency of compressor switching cycles. Door adjustment Atlant is carried out using hinges.

First, check the horizontal installation of the refrigerator itself. If the floor is uneven, the door may open spontaneously or not close completely. Use a building level to check. If the refrigerator is tilted backwards or to the side, this must be corrected using adjustable supports located in the front lower part of the case.

If there are no distortions in the floor, but the door hangs crookedly, adjustment of the hinges will be required. Usually the top hinge is fixed with screws under the decorative trim. By loosening the fasteners, you can move the door up, down, left or right, achieving uniform clearance around the entire perimeter. After alignment, the fasteners need to be tightened.

In two-chamber models with a No Frost or mixed type system, the air damper (damper) plays an important role. It regulates the flow of cold air from the freezer to the refrigerator compartment. If the damper is stuck open, the upper chamber will be too cold and everything will freeze. If it is closed, it is warm.

• 🔧 Check the cleanliness of the air supply channel - it should not be clogged with products.
• ❄️ Make sure that the damper moves freely, without mechanical obstacles.
• 🚪 Test the tightness of the door after adjusting the hinges with a sheet paper.

⚠️ Attention: When adjusting the hinges, do not remove the door completely if you are not confident in your abilities. Refrigerator doors are heavy and easy to drop, damaging the floor or legs.

Aligning the body and adjusting the supports

Stable operation of the compressor and the correct distribution of refrigerant in the system depend on the position of the refrigerator in space. The instructions for Atlant state that deviation from the vertical is allowed no more than 2 degrees. However, for gravity flow of oil into the compressor and correct operation of the condensate drainage system, it is better for the device to stand perfectly level, with a slight, barely noticeable tilt back.

Adjustment is carried out by two front support screws (legs). They screw into the bottom of the front panel. By rotating them clockwise, you raise the corner of the refrigerator, counterclockwise, you lower it. The rear wheels or supports are usually unadjustable and serve only to roll the equipment.

Why is a slight tilt back important? This provides the door with a self-closing effect. If the door is opened less than 30-40 degrees, it should close itself under the influence of gravity. If the door remains open or, conversely, slams too hard, the angle of inclination is incorrect.

An unstable position of the refrigerator leads to increased vibration. The compressor, when operating, creates vibrations that are transmitted to the housing. If the refrigerator is positioned crookedly, vibration increases, causing rattling of shelves, bottles and increased noise. This is not only annoying, but can also lead to loosening of the internal fastenings of the unit.

Table of optimal settings for different seasons

External temperature environment directly affects the operation of refrigeration equipment. In summer, when the kitchen is hot, heat flow through the walls of the refrigerator increases. In winter, on the contrary, it may be cooler in a heated room, but if the refrigerator is on an unheated loggia, the situation changes dramatically. For models Atlant the following recommendations are relevant:

It is important to understand that a mechanical thermostat does not know about the temperature outside. It only reacts to the temperature inside the chamber. Therefore, seasonal adjustment of the position of the handle is the responsibility of the owner, allowing to compensate for external factors and maintain stable climate inside.

*Note: Most refrigerators Atlant are intended for operation in climate class N (normal), that is, at ambient temperatures from +16 to +32 degrees. Operation at lower temperatures can lead to solidification of the oil in the compressor and disruption of refrigerant circulation.

What to do if the refrigerator is on an unheated loggia?

If the temperature drops below +10 degrees, the thermostat may not “see” that it is warm in the chamber, and do not turn on the compressor. The food will begin to defrost. In such cases, it is necessary to install a special thermostat heater or transfer the equipment to a warm place.

Typical errors during adjustment and their consequences

Many users, trying to “improve” the operation of the refrigerator, make mistakes that nullify all efforts. The most common one is to set the regulator to the maximum value (7 or Max) in the hope that the food will be stored better. In practice, this leads to continuous operation of the compressor, freezing of the evaporator and, as a result, deterioration of cooling.

Another mistake is ignoring the loading of the chambers. An empty refrigerator and a completely stocked refrigerator require different settings. If you have loaded your freezer to capacity with fresh meat, it makes sense to temporarily turn on the super-freeze mode, but then be sure to return the settings to normal mode. Constant work at the limit of capabilities reduces the service life of equipment.

Incorrect assessment of tightness is often encountered. Users think that if the door closes, then everything is fine. However, microcracks in the seal or contamination of the magnetic tape can allow enough air to leak to upset the temperature balance. Regular washing and lubrication of the seal (for example, with glycerin or a special silicone grease) is part of the process of “adjusting” the condition of the equipment.

Do not forget about the placement of products. If you crowd the back wall of the refrigerator compartment tightly with pots, you will block the air circulation channels. The cold will not be distributed evenly, and the temperature sensor will show incorrect values, causing the compressor to work incorrectly.

Diagnosis of problems after adjustment

After you have made all the adjustments, you need to wait time for the processes to stabilize. The refrigerator needs from 4 to 6 hours (sometimes up to a day) to reach the specified temperature conditions and form the correct operating cycle. You should not evaluate the result immediately after turning the knob.

If after adjustment and stabilization you observe the following signs, perhaps the problem is deeper than just the setting:

• 🔊 The compressor hums constantly, without turning off, and the temperature is not reached.
• ❄️ On the back wall of the refrigerator compartment a “fur coat” is formed even with minimal settings.
• 💧 There is water inside the chamber, although the drainage hole is clean.
• 🌡️ The temperature in the chambers strongly fluctuates (jumps) even with the regulator position unchanged.

In such cases, it may be required replacing the thermostat, defrost system repair or refrigerant refill. Self-adjustment will no longer help here, since the physics of the operation of the units is disrupted. However, correctly set parameters will help the technician quickly diagnose the malfunction, eliminating the factor of improper operation.

Remember that regular maintenance and proper adjustment are the key to the fact that your Atlant will serve the stated 10-15 years and even more. Do not neglect simple rules, and the equipment will reward you with stable operation.

How often should you check the settings?

It is enough to check the position of the regulator when the seasons change (spring/autumn) or when the temperature in the room changes significantly. The check is also carried out after complete defrosting or general cleaning.

What to do if the thermostat knob scrolls endlessly?

If the knob turns without noticeable resistance or clicks, most likely the thermostat itself has failed (broken bellows or rod). In this case, adjustment is impossible; the part must be replaced. Before the technician arrives, you can try to carefully remove the handle and check whether the stem inside is intact.

Is it possible to adjust the Atlant refrigerator if it is standing close to the wall?

No, this is a critical error. For correct operation of the condenser (radiator at the back or on the sides), a gap of at least 5-10 cm from the wall is required. Without ventilation, the refrigerator will overheat, and no adjustment of the temperature inside will help - it simply will not be able to transfer heat effectively.

Why, after adjusting the door, did it become worse to close?

Perhaps you violated the geometry when adjusting the hinges or packaging/product got into the gap. Also check whether the body itself is warped when the support legs rotate. Return everything to its original position and repeat the alignment procedure more carefully, using a level.

Do you need to change the settings when the power goes out?

There is no need to specifically change the settings. However, if there has been no light for a long time and the food has defrosted, after turning it on, it is advisable to temporarily set a more intensive cooling mode (closer to Max) for 2-3 hours in order to quickly increase the temperature, and then return the regulator to its normal position.

Does the number of products affect the setting?

Yes, it does indirectly. A full chamber holds the cold better (the products act as a cold accumulator), so the compressor can turn on less often. An empty refrigerator heats up faster when the door is opened. In the summer, when fully loaded, you can slightly reduce the power, and when empty, add more, but within reasonable limits.
