The safety of food directly depends on the correct operation of the climate system of your refrigerator. Many equipment owners Atlant face a situation where milk turns sour faster than usual or vegetables in the bottom drawers begin to freeze. This is a sure sign that the temperature regime is down and requires immediate adjustment.
The two-chamber models of this Belarusian brand, be it the classic series or modern versions with No Frost, are designed to operate in a strictly defined range. Understanding the physical processes of cold air circulation will help you set up the appliance so that it consumes less electricity and food stays fresh for as long as possible.
In this article we will look in detail at what indicators are considered standard for different zones of the refrigerator compartment, how to turn the regulator correctly and why the numbers on the scale do not always correspond to degrees Celsius. You will learn to diagnose cooling problems without calling a technician.
Standard temperature standards for different zones
The refrigerator compartment is not a single monolith with the same temperature everywhere. Due to the laws of physics and the peculiarities of air flow circulation, zones with varying degrees of cooling are formed inside. In two-chamber models Atlant the cold distribution is uneven, which must be taken into account when arranging food.
The coldest zone is traditionally considered to be the area near the back wall, especially in models with drip system defrosting. Here the temperature can drop to the minimum values specified in the technical data sheets. That is why it is better to store dairy products and meat on the middle shelves, away from the back panel, to avoid their premature spoilage or freezing.
The refrigerator door is the warmest place in the entire device. Constantly opening the door causes indoor air to come into contact with warm room air. Therefore, shelves on the door are ideal for storing sauces, drinks and products that do not require deep refrigeration, but not for perishable food.
The lower drawers, often called the “fruit drawer” or “freshness zone,” have their own microclimate. Depending on the design of a particular model Atlant, the temperature here can be slightly above average, which prevents vegetables from freezing, or it can be specially cooled for long-term storage. It is important to understand that the ideal average temperature for the main storage area is +3...+5°C.
How to correctly set the thermostat in the Atlant refrigerator
Temperature control in refrigerators Atlant is carried out using a mechanical or electronic thermostat. Most classic dual-chamber models use a mechanical rotary switch located inside the camera or on the top panel of the housing. The scale of such a regulator usually contains numbers from 1 to 7 (or from Min to Max).
It is critically important to understand the operating principle of this device: the number on the scale does not mean the number of degrees Celsius. It denotes work intensity compressor. The higher the number you set, the colder it will be inside the chamber. Setting the regulator to maximum (7 or Max) forces the motor to work almost without interruption, which can lead to icing of products and increased electricity consumption.
For everyday use in the middle zone, it is recommended to set the regulator to value 3 or 4. This is the “golden mean” in which the refrigerator is able to maintain the required +4°C even when the ambient temperature in the kitchen increases in the summer. If you have just loaded a large amount of warm food, you can temporarily increase the cooling, but then be sure to return the switch to normal mode.
On models with electronic control settings are made via the display on the door. Here you set specific degrees. However, even in this case, it is worth remembering the inertia of the system: changing the settings will affect the actual temperature inside the chamber only after a few hours.
Factors affecting the cooling of products
Even with the regulator set correctly, the temperature inside the chamber may fluctuate. There are many external and internal factors that affect the efficiency of the refrigerator Atlant. Ignoring these factors often leads to false conclusions about equipment failure.
One of the main enemies of proper cooling is dense loading. If shelves are filled to capacity with food, cold air cannot circulate. As a result, some corners of the chamber will be warm, while others will be extremely cold. Air should flow freely around each product.
It is also worth considering the frequency of door opening. Every time you open your refrigerator, warm, moist air enters. If the house is hot or humid (for example, it is raining or soup is cooking), the load on the compressor increases many times over. During such periods, the refrigerator may not have time to gain cold, and the temperature will temporarily rise above normal.
The technical condition of the door seals plays an equally important role. The rubber cuff should fit snugly around the entire perimeter of the body. If a gap has formed somewhere, the cold will escape, and warm air will constantly flow in, forcing the thermostat to keep the compressor on.
⚠️ Attention: If you notice that a “coat” of ice more than 5-7 mm thick is forming on the back wall of the refrigerator compartment, this is a signal of a violation of the temperature regime or a malfunction of the defrost system. Operation in this mode is harmful to equipment.
Table of temperature zones and food storage
For the convenience of distributing food supplies inside a two-chamber refrigerator Atlant a reference table has been compiled. It will help you arrange the contents so that the product is in the most suitable conditions for it.
| Refrigerator area | Approximate temperature | What to store | Shelf life (approximate) |
|---|---|---|---|
| Top shelf | +5...+7°C | Ready meals, cakes, yoghurts | 2-3 days |
| Middle shelves | +3...+5°C | Dairy products, sausages, cheeses | 3-5 days |
| Bottom shelf (above the drawers) | +2...+4°C | Raw meat, fish, semi-finished products | 1-2 days |
| Door shelves | +7...+10°C | Sauces, drinks, eggs, oil | Depends on the product |
| Freshness zone (zero zone) | 0...+2°C | Chilled meat, fish, herbs | Up to 7 days |
Using this table will allow you to use the resource of your refrigerator as efficiently as possible. Please note that storing raw meat and fish on the top shelves is unacceptable, since dripping juice can infect bacteria with the products lying below.
Diagnostics of problems: why it doesn’t hold up temperature
If you notice that food is spoiling faster, and the inside of the chamber is clearly warmer than it should be, it is necessary to carry out an initial diagnosis. The reason is not always a compressor failure or freon leak. Often the problem is solved by simple actions.
First of all, check whether air ductsare not blocked. In modern models Atlant with an air distribution system, cold is pumped through special channels. If you place the pan directly in front of the air outlet, the circulation will stop and the temperature sensor will no longer receive correct data.
The second important point is the location of the refrigerator. If it stands close to a wall or in a niche without gaps for ventilation, heat from the condenser (grids at the back or on the sides) is not removed. This leads to overheating of the unit and reduced cooling efficiency. The minimum gap to the wall should be 5-10 cm.
It is also worth checking the operation of the thermostat. If the refrigerator is “silent” (the compressor does not turn on) when it is clearly warm inside, the temperature controller itself or the start relay may have failed. In such cases, specialist intervention is required.
⚠️ Attention: It is strictly forbidden to use sharp objects (knives, screwdrivers) to remove ice from the evaporator or chamber walls. A puncture of the evaporator will lead to an immediate release of freon and expensive repairs, which are often not economically feasible.
Seasonal operating conditions and energy consumption
The ambient temperature directly affects the operation of refrigeration equipment. In the summer, when the apartment is +25...+28°C, the refrigerator Atlant has to work harder to maintain the internal +4°C. In winter, with ventilation or low temperatures in the room, the load drops.
There is a concept climate class refrigerator. Most Atlant models belong to the SN-T or SN-ST class, which means they can operate at ambient temperatures from +10 to +38 (or +43) degrees Celsius. If you plan to install the refrigerator in an unheated country house in the winter, where the temperature drops below +10°C, the standard model may not start or may not work properly.
In the summer, it is recommended to check the tightness of the door more often and, if necessary, wipe the seal. Also, in summer, you should not load hot products into the chamber - this will give a powerful jump in temperature and humidity, which will make the compressor work harder.
☑️ Checking the operation of the refrigerator
Maintaining the cooling system for a stable temperature
So that the temperature in the refrigerator compartment always corresponds to the norm, for equipment needs to be maintained. Even modern systems No Frost or Low Frost require user attention. Cleanliness inside the chamber is not only hygiene, but also the key to proper operation of the sensors.
Regularly, at least once a quarter, it is recommended to carry out defrosting (for drip systems) or general cleaning. During this procedure, you need to thoroughly rinse the drainage hole through which moisture escapes. If it becomes clogged with crumbs or mold, water will begin to accumulate at the bottom, which can lead to increased humidity and disruption of heat transfer.
You should also periodically check the cleanliness of the condenser (black grill) at the back of the refrigerator. A layer of dust several millimeters thick acts as a heat insulator, preventing heat transfer. This causes the compressor to run longer but cool less. Vacuum the grille carefully so as not to damage the tubes.
⚠️ Attention: When cleaning the rear condenser grille, do not use wet cloths or detergents. Dry clean only with a soft brush or vacuum cleaner. Moisture getting on the electrical contacts of the compressor is dangerous.
Why does ice freeze on the back wall in the Atlant refrigerator?
In models with a drip system (crying evaporator), ice freezing is a normal operating process. While the compressor is operating, moisture from the air freezes on the rear wall. When the compressor turns off, the wall heats up, the ice melts and flows into the drain. The problem occurs if the ice does not have time to melt (the door is opened too often, the thermostat is faulty) or if the drainage is clogged.
Frequently asked questions (FAQ)
Why does the Atlant refrigerator freeze food on the shelf next to the back wall?
This is typical for a drip cooling system. The rear wall is the evaporator, and the temperature on it is always lower than in the center of the chamber. Try not to place food close to the back panel, leaving a gap of 2-3 cm for air circulation.
What number should you set on the regulator in the summer?
In the summer, when the room is hot, it is recommended to set the regulator to value 4 (or closer to Max, but not to the maximum). This compensates for the high external temperature, allowing the compressor to gain the required cold.
Why is the top shelf warmer than the bottom?
Warm air is lighter than cold air and rises. Therefore, in the upper part of the chamber the temperature will always be 1-2 degrees higher than in the lower part. This is a physical norm, not a malfunction.
Is it possible to place the Atlant refrigerator near the battery?
It is highly not recommended. The battery heats the side of the refrigerator where the condenser is located. This dramatically reduces cooling efficiency and increases energy consumption. The minimum distance from the battery to the refrigerator must be at least 50-60 cm, or a heat-insulating screen is required.
What to do if the refrigerator is humming and does not turn off?
If the compressor works without interruptions and does not turn off, and the temperature inside does not drop to normal, the following options are possible: freon leak, thermostat malfunction or loss circuit tightness. It is necessary to defrost the refrigerator for 10-12 hours. If after turning on the problem repeats, call a technician.
