Correct regulation of climatic conditions inside the refrigeration chamber is the foundation for long-term storage of products and preservation of their taste. Owners of Belarusian brand equipment are often faced with the need for precise calibration, especially after loading a large volume of products or changing the season. The system No Frostimplemented in modern models requires a special approach, since air circulation here is forced, and not due to natural convection.
Incorrect settings can lead to drying out of vegetables or, conversely, to the formation of an ice crust on food. Understanding how your device works will help you avoid these problems and reduce your energy consumption. In this article we will look in detail at how to set the optimal mode for different operating conditions.
It is important to consider that different series of refrigerators Atlant may have differences in control. Somewhere a mechanical regulator is used, and somewhere a full-fledged electronic display. Adjustment accuracy directly affects the service life of the compressor and the efficiency of the moisture removal system.
Principles of operation of the No Frost system in Atlant models
System No Frost (translated as “no frost”) in Atlant refrigerators is based on the constant circulation of cooled air inside the chambers. Unlike old models with a “crying” wall, here moisture does not settle on the products, but is removed through a special drainage. This ensures uniform temperature in all corners of the refrigerator, but requires correct initial settings.
The air is forced by a fan and passes through the evaporator, hidden behind the rear panel. There it is cooled and dried, after which it is returned to the chamber. Circulation flows can be quite intense, so it is important to position the products correctly so as not to block the air outlet openings. If the dampers are closed, the temperature sensors may read incorrect data.
The key control element is thermostat or an electronic module that reads readings from the sensors. Based on this data, he decides whether to turn the compressor on or off. In models with two compressors, the refrigeration and freezer compartments are adjusted independently, which gives more flexibility.
Why can frost appear in No Frost?
Despite the name of the system, a small amount of frost can form on the evaporator during operation. Once every 6-12 months (depending on the model), automatic defrosting occurs when the heating element melts the ice. If you see ice inside the chamber on the products, this is a sign of a leak or incorrect setting, and not a failure of the No Frost system.
Determining the type of control: mechanics or electronics
Before you begin adjustment, you need to determine exactly what type of control is installed in your model Atlant. The algorithm of actions and the available range of settings depend on this. Erroneous attempts to configure the electronic menu mechanically will lead to nothing.
Most often found in budget and mid-range models mechanical thermostat. This is a rotary knob, usually located inside the refrigerator compartment on the ceiling or top wall. It contains numbers from 1 to 7 (or from Min to Max), which indicate the cooling intensity, not degrees Celsius.
More advanced series are equipped with electronic control unit (ECU). It can be located on the outside door or inside the chamber. Here the temperature is set in degrees Celsius with an accuracy of 0.5 or 1 degree. The presence of a display greatly simplifies control, but requires careful handling.
Setting a mechanical thermostat
Temperature adjustment in models with mechanical control is carried out by turning the handle. The numbers on the scale indicate the level of cooling power: the higher the number, the lower temperature inside the chamber. It is important to understand this logic so as not to freeze food by mistake.
The optimal position for year-round operation is considered to be “3” or “4”. This provides a balance between power consumption and storage quality. Setting the regulator to the maximum (6-7) is allowed only in emergency cases, for example, when quickly freezing a large volume of food, but for no more than a few hours.
After changing the position of the knob, you should not expect an instant result. Thermostat it takes time (from 2 to 6 hours) to stabilize the climate inside the volume. Frequent twisting of the handle “back and forth” disorients the system and leads to increased wear on the compressor.
- 🌡️ Position 1-2: Minimum cooling, suitable for storing drinks or at very low room temperatures.
- ❄️ Position 3-4: Standard mode for daily use of most products.
- 🧊 Position 5-7: Intensive freezing mode, requires control to avoid spoilage of vegetables and fruits.
Adjustment of the electronic control unit
In models with electronics, the setup process looks different and provides the user with more options. Here you operate with specific values in degrees Celsius. For the refrigerator compartment, the standard range is from +3 to +5 °C, and for the freezer - from -18 to -24 °C.
To change the settings, you usually need to press and hold the setting button (often indicated by a thermometer symbol or an asterisk) for 3-5 seconds until the numbers begin to flash. After this, use the “+” and “-” or “Up/Down” buttons to set the desired value. Confirmation occurs automatically after a few seconds or by pressing the same button.
Modern models Atlant often have a function super freeze (Super Freeze). When this mode is activated, the compressor works without stopping, quickly lowering the temperature in the freezer to -24 °C and below. This is useful when loading fresh products, but you must not forget to turn off this mode.
☑️ Checking the settings of the electronic unit
⚠️ Attention: In some models, if the power is turned off, the settings may be reset to factory values. After resuming the power supply, be sure to check the set parameters so that the products do not become defrosted.
Seasonal adjustment and environmental influence
The temperature in the room where the refrigerator is installed directly affects its operation. In the summer, when the room is hot, the compressor has to work harder to maintain the set temperature. In winter, when central heating is operating, the situation is similar, but there are nuances with installation near a window or on an unheated loggia.
If the refrigerator is located near a heat source (battery, stove, direct sunlight), sensors can read the increased temperature and force the motor to work to the limit. In such cases, it is permissible to shift the setting by 0.5–1 degree towards lower values, but it is better to eliminate the heat source.
In winter, if the temperature in the room drops below +16 °C (for example, in a country house or balcony), standard refrigerators may stop turning on or work intermittently. This is due to the fact that the refrigerant has nowhere to give off heat, and the thermostat “thinks” that it is already cold inside. For such conditions, a special climate class techniques.
| Indoor conditions | Recommended setting (Mechanics) | Recommended setting (Electronics) | Note |
|---|---|---|---|
| Summer (+25...+30°C) | 4 - 5 | +3...+4°C | Increase the gap at the back wall |
| Normal (+18...+22°C) | 3 - 4 | +4...+5°C | Standard mode work |
| Winter/Cool (+16...+18°C) | 2 - 3 | +5...+6°C | Monitor the compressor operation |
| Loading fresh products | Temporarily for 5-6 | Super mode Freeze | Return after 12-24 hours |
Typical errors when setting the temperature
One of the most common mistakes is setting the minimum temperature immediately after defrosting or turning it on for the first time. An empty refrigerator will quickly cool down, but the sensor may not have time to react, and the products you put inside will be in the extreme cold zone, which will lead to their spoilage.
Another mistake is ignoring the fullness of the chamber. A half-empty refrigerator loses cold every time you open the door, forcing the compressor to turn on frequently. On the contrary, a tightly packed refrigerator (but without blocking the ventilation) holds the temperature better. Heat capacity products help stabilize the climate.
Incorrect placement of temperature-sensitive elements can also throw off the settings. If you put a hot pan right next to the sensor (in models where it is visible) or block the air flow to it, the refrigerator will “think” that it is already cold inside and will turn off until the food in the far corner spoils.
- 🚫 Overload: Do not overcrowd the chamber at once, let the air circulate.
- 🔥 Hot products: Never put hot food inside, it will upset the settings and spoil neighboring products.
- 🌬️ Ventilation: Do not cover the cold air outlets with vegetables or bags.
⚠️ Attention: If you notice that the back wall of the refrigerator compartment is covered with a solid crust of ice (in No Frost models this is unacceptable), the drainage hole may be clogged or the defrosting heating element is faulty, and not the temperature is incorrectly set.
Diagnostics of problems with temperature conditions
How understand that the settings are wrong or the equipment is faulty? The first sign is a change in the taste or consistency of foods. If the milk turns sour quickly and the meat turns grey, the temperature is too high. If cucumbers turn into ice and bread goes stale in a couple of days, the refrigerator “freezes.”
For accurate diagnosis, it is recommended to use an external thermometer placed in a glass of water on the middle shelf. Leave it overnight. The readings must correspond to the established values with an error of no more than 1-2 degrees. If the spread is greater, you need to call a technician to calibrate or replace the thermostat.
Continuous operation of the compressor without turning off is a sure sign that the refrigerator cannot reach the set temperature. This may be caused by a freon leak, wear of the door seal, or a malfunction of the door seal itself. In such cases, simple reconfiguration will not help. thermostat. In such cases, a simple reconfiguration will not help.
What to do if the refrigerator is humming, but not cooling?
If the compressor is working, but there is no cold, check whether you have blocked the ventilation channels inside the chambers. If this is ok, the start relay may be stuck or there may be a refrigerant leak. It is dangerous to get into the system with freon on your own; you need a specialist.
Frequently asked questions (FAQ)
Why does ice freeze on the back wall in the Atlant No Frost refrigerator?
In the No Frost system there should be no ice on the walls of the chamber. If it appears, check the tightness of the door, the integrity of the seal, and whether the drainage hole is clogged. This may also be a sign of a malfunction of the evaporator defrost system.
What temperature should be set in the summer if the apartment is hot?
In the summer it is recommended to set the value 1 division higher than usual (for example, “4” instead of “3” on mechanics or +3°C instead of +5°C on electronics). However, the main thing is to ensure good ventilation around the refrigerator body and move it away from the radiator or stove.
Is it possible to store a refrigerator at sub-zero temperatures on the balcony?
Most Atlant models have a climate class of SN-N-ST, which means operating at ambient temperatures from +10 to +32°C. Operation at sub-zero temperatures can lead to oil solidification in the compressor and equipment breakdown. Special models are needed for the balcony.
How often do you need to defrost a No Frost refrigerator?
The No Frost system does not require regular defrosting by the user, as it occurs automatically. However, 1-2 times a year it is recommended to completely defrost, wash and disinfect the chambers to maintain hygiene and remove odors.
Why, after setting the temperature, does it not change immediately?
The refrigerator needs time to stabilize the heat balance. After changing the settings, the compressor must run a full cycle for the new mode to take hold. This usually takes from 2 to 6 hours, depending on the workload of the chambers and the temperature in the room.
