Two-chamber refrigerators Atlant with system No Frost are deservedly popular due to their reliability and the absence of the need for regular defrosting. However, many owners encounter difficulties during the initial setup or changing climate modes, since the temperature control here differs from classic models with a drip system. Incorrect adjustment can lead to damage to products or excessive energy consumption.
In this article we will look in detail at how to correctly set the necessary parameters, what the numbers on the regulators mean and why it is important to take into account the location of the products. You will learn about the nuances of the operation of thermostats and electronic control systems characteristic of modern models of the Belarusian manufacturer. Correct settings will extend the life of the compressor and keep your supplies fresh.
Before you start changing settings, you need to make sure that the unit is installed level and the doors fit tightly. Temperature conditions directly depends on the tightness of the chambers and proper circulation of cold air. Ignoring basic operating rules can negate all efforts for accurate calibration.
The principle of operation of the No Frost system and climate control
The system No Frost (translated as “no frost”) operates on the principle of forced circulation cooled air. Unlike crying evaporators, here the cold is distributed by a fan evenly throughout the entire volume of the chamber. This is why adjusting the temperature in the refrigerator Atlant requires understanding that the air here is dry and moves faster. This eliminates the formation of an ice crust on the walls, but dictates its own rules for storing food.
Climate control in different models can be carried out by a mechanical thermostat or an electronic panel. In mechanical models, you do not set the degrees directly, but select the conditional cooling power. Electronics allows you to set the exact value in degrees Celsius, which greatly simplifies control. Setting accuracy is critical for preventing over-drying of vegetables or insufficient freezing of meat.
⚠️ Attention: In refrigerators with No Frost, you cannot completely block the ventilation holes inside the chamber with food, otherwise The temperature sensors will read incorrect data and the compressor will work under overload.
It is important to understand the difference between the main chamber and the freezer. In two-chamber models, these zones are independent, but connected by a common refrigerant system. Changing the mode in one zone can indirectly affect the operation of another, especially in models with a single compressor. Therefore, adjustments should always be made comprehensively, assessing the condition of the products in both compartments.
Deciphering the scale of a mechanical thermostat
In most models Atlant with mechanical control, the regulator is a rotary knob with numbers from 1 to 7 (sometimes up to 5). Many users mistakenly believe that the number corresponds to the temperature in degrees. In fact, this is an indicator cooling power: the higher the number, the colder it will be inside.
Position “1” means minimum power - the temperature will be the highest (closer to 0°C or even higher depending on the load). Position “7” (or “Max”) causes the compressor to work almost non-stop, creating extremely low temperatures. The golden mean for everyday use is considered to be a position between 3 and 4. This is the optimal balance between food safety and energy consumption.
There is also an intermediate position, often indicated by a dot or the word “Off”. In this mode, the cold supply stops and the refrigerator only works for defrosting or is turned off. Switching to this mode should only be done when defrosting is necessary or the equipment will be idle for a long time. Constant operation in the “Max” mode will quickly cause compressor to fail.
Setting up the electronic control panel
Modern series Atlant are equipped with digital displays located on the outside of the door or inside cameras. Here the adjustment is made with an accuracy of one degree. Typically the adjustment range for the refrigerator compartment is +3°C to +7°C, and for the freezer compartment -6°C to -24°C. To change the values, use the “+” and “-” buttons or touch symbols.
When turning on for the first time or after defrosting, it is recommended to set the standard factory values: +4°C for the refrigerator and -18°C for the freezer. The electronics itself stabilizes the mode within several hours. If you notice that food is freezing at the back wall, you can increase the temperature by 1-2 degrees. Conversely, if the meat does not freeze, the value in the freezer needs to be lowered.
Some models have indicators that blink when they deviate from the set parameters. If after setting the numbers continue to flash or a beep is heard, check that the door is closed tightly. Electronics are sensitive to voltage changes, so if there are surges in the network, the settings may be lost and will have to be set again.
Optimal temperature conditions for different products
Correct temperature settings directly affect the shelf life of products. In the refrigerator compartment Atlant there are zones with different temperatures, even if the general mode is set correctly. Understanding this gradation will help you place inventory in the most efficient way. Below is a table of recommended parameters.
| Product type | Recommended temperature | Refrigerator storage area | Shelf life (approximate) |
|---|---|---|---|
| Fresh meat and fish | 0°C ... +2°C | Zero zone (Bio Fresh / Fresh Zone) | 1-3 days |
| Dairy products | +2°C ... +4°C | Middle shelves, closer to the back wall | 3-5 days |
| Vegetables and fruits | +4°C ... +7°C | Bottom drawers (vegetable containers) | 5-10 days |
| Ready meals | +2°C ... +5°C | Middle and upper shelves | 2-3 days |
Particular attention should be paid to the “zero zone” if it is provided in your model Atlant. This is a special compartment where the temperature is maintained at about 0°C and high humidity. You cannot store food here that is sensitive to the cold, such as bananas or tomatoes. The top shelves, where the temperature is slightly higher, are better suited for them.
The freezer should provide deep freezing. The optimal value is -18°C. At this temperature, bacteria do not multiply, and the structure of the products is preserved for months. If you plan to store supplies for more than 3 months, it makes sense to lower the temperature to -20°C ... -22°C, but this will increase energy consumption.
Common mistakes when adjusting
One of the most common mistakes is trying to quickly cool hot products by setting the regulator to maximum. Thermostat not is able to instantly change the temperature, and the compressor will receive excess load. Hot food must first be cooled to room temperature, and only then put in the refrigerator.
⚠️ Attention: Never immediately set the mechanical thermostat control to the maximum value (7 or Max) in hot weather. This can lead to the door freezing and making it impossible to open it without damaging the seal.
Another common mistake is ignoring seasonal changes. In summer, when the room is hot, the refrigerator requires more intensive work. In winter, on the contrary, the load can be reduced. If you have a mechanical model, in summer it is better to keep the knob at 3-4, and in winter you can lower it to 2-3 if the room is cool.
☑️ Checking the settings correctly
Also, users often forget that the chambers are full. An empty refrigerator cools faster, but holds the temperature worse when the door is opened. A unit that is too full prevents air circulation. The optimal filling of the refrigerator volume is about 70-80% to ensure proper convection.
What to do if the temperature does not hold
If you have set the correct settings, but the food spoils or, conversely, freezes, the problem may not be regulator First of all, check the rubber seals on the doors. If they are worn out or dirty, the cold will go away, and the thermostat will drive the compressor without rest. Wipe the seal with a soft cloth and check the seal.
In models Atlant with No Frost, the condensate drain channel sometimes becomes clogged or the defrost sensor fails. In this case, a “coat” of ice may grow in the chamber, which blocks the flow of cold air. As a result, the temperature sensor “thinks” that the chamber is warm and turns on the compressor, although in fact the air simply does not circulate.
How to check the operation of the thermostat without instruments?
Place a glass of water in the middle of the refrigerator compartment and put a household thermometer in it. After 2-3 hours, check the readings. If they differ greatly from those set on the regulator (by more than 2 degrees), the thermostat may require calibration or replacement.">To accurately diagnose a malfunction of the thermostat or sensors, you need to call a technician with special equipment. Replacing these elements on your own in No Frost refrigerators can lead to a leak in the system.
If the refrigerator makes unusual sounds or operates cyclically with very short breaks, this may indicate a leak. refrigerant or problem with the fan. In such cases, simply resetting the temperature will not help - you will need professional repair.
Seasonal adjustment and energy efficiency
External ambient temperature significantly affects the operation of refrigeration equipment. data-i="134">says that the equipment is designed to work in a certain climate class (usually from +10°C to +32°C or +43°C). If the kitchen is colder than +10°C (for example, in winter in an unheated country house), the refrigerator may stop turning on, since the thermostat will “seem” that it is already cold. Atlant states that the equipment is designed to work in a certain climate class (usually from +10°C to +32°C or +43°C). If the kitchen is colder than +10°C (for example, in an unheated country house in winter), the refrigerator may stop turning on, since the thermostat will “seem” that it is already cold.
In the summer, when the room temperature rises, heat transfer deteriorates. During this period, it is not recommended to set the knob to minimum (number 1), since the products may spoil. However, turning the knob to maximum (number 7) is also dangerous. It is better to leave the middle position and check the condition of the products more often. Electronic models themselves adapt to external conditions, but they also need help by providing ventilation to the rear grille.
Remember that every extra degree of cold is extra kilowatts. The difference between mode “3” and “5” on a mechanical regulator can be up to 20% of the energy consumed. Therefore, do not try to freeze everything “just in case” if this is not directly necessary.
Why does ice freeze in the refrigerator compartment of Atlant No Frost if it shouldn’t be there? be?
An accumulation of ice in the No Frost system usually indicates a malfunction of the defrost system. This could be a burnt-out evaporator heating element, a faulty defrost timer or a temperature sensor. Ice can also appear if you have kept the door open for a long time and humid air has entered, or if the drainage hole is clogged with debris.
Is it possible to set the temperature below -24 degrees. in the Atlant freezer?
In most household models Atlant the minimum threshold is limited to -24°C. Setting lower values is technically impossible without reprogramming the electronics (if any) or intervening in the mechanics, which is not recommended. Temperatures below -24°C do not provide significant benefits for food storage, but significantly increase wear. compressor.
How long does the Atlant refrigerator keep cold during a power outage?
The time it keeps cold depends on the model, load volume and room temperature. On average, two-chamber refrigerators Atlant with the No Frost system keep the temperature in a safe range (up to +9°C) for 10-17 hours with the doors completely closed. The more tightly the shelves are packed, the longer the cold remains.
What does the flashing temperature indicator on the panel mean?
A flashing indicator usually indicates that the temperature in the chamber is above the set norm. This happens immediately after turning on. after loading warm food or when the door is not tightly closed. If the indicator blinks constantly after the refrigerator has been running for several hours, the sensor may be faulty or there is a freon leak.
Is it necessary to defrost the Atlant No Frost refrigerator?
The No Frost system assumes that there is no need for regular defrosting to remove ice. However, sanitary defrosting and washing are recommended. 1-2 times a year to remove bacteria and odors. At this time, the equipment must be unplugged, washed and dried.
