Correct setting of the temperature regime in the refrigerator Atlant
is the foundation for long-term preservation of products and efficient operation of the compressor. Errors in adjustment often lead to food spoilage, unpleasant odors or excessive energy consumption. The owner must understand that each model, be it a classic two-chamber Atlant 4008 or a modern unit with a system No Frostrequires an individual approach.In this article we will analyze the physical principles of operation of thermostats and electronic control panels. You will learn why you cannot blindly trust the factory settings and how seasonal changes affect operation refrigeration circuit. Proper calibration will extend the life of your equipment.
Principles of operation of the thermostat in Atlant refrigerators
Mechanical thermostats installed in most models Atlantoperate on the principle of closure and opening the electrical circuit depending on the temperature of the sensitive element. Inside the chamber there is a capillary tube that responds to changes in the thermal background. When you turn the knob, you change the spring tension, which shifts the contact threshold.
It is important to understand that the numbers on the thermostat scale (usually from 1 to 7) do not indicate degrees Celsius. They reflect cooling intensity. One means the minimum cooling capacity, and seven means the maximum. Many users mistakenly believe that the number 1 is +1°C, which is a gross misconception. In fact, position “1” can correspond to a temperature of about +8...+10°C, and position “7” can freeze food in the main chamber.
⚠️ Attention: Never set the mechanical type regulator to the maximum value (7 or Max) to quickly freeze a large volume of food. This can lead to the compressor freezing and overheating, since the shutdown sensor may not respond in time.
Electronic control systems, found in more expensive series, use thermistors to accurately measure temperature. Here you set specific degrees, and microprocessor he decides when to turn on the motor. Such systems are devoid of mechanical inertia, but require a stable voltage in the network.
Optimal temperature conditions for different products
To ensure food safety, certain temperature ranges must be observed. In the main chamber of the refrigerator Atlant the most favorable area for storing most products is the middle shelf, where the temperature remains stable. However, different groups of goods require different conditions.
Dairy products, ready meals and meat delicacies are best preserved at a temperature of +2 to +4°C. Vegetables and fruits, on the contrary, can suffer from cold at temperatures below +4°C, losing moisture and taste. Frozen food in the freezer should be stored at a temperature not exceeding -18°C to preserve the cell structure.
| Product type | Optimal temperature (°C) | Recommended shelf | Shelf life (approximate) |
|---|---|---|---|
| Fresh meat/poultry | 0...+2 | Lower shelf (freshness zone) | 1-2 days |
| Dairy products | +2...+4 | Middle shelves | 3-5 days |
| Vegetables/Fruits | +4...+8 | Bottom drawers (vegetables) | 3-7 days |
| Ready meals | +2...+5 | Middle/Upper shelves | 1-2 days |
Use Freshness zones (if it is provided by the model, for example, in the series Atlant XM-4425) allows you to store food at a temperature of about 0°C without freezing. This is ideal for chilled meat or fish that you plan to cook in the near future.
Instructions: how to set the temperature in single-compressor models
Single-compressor refrigerators Atlant have one cooling system for both compartments. This means that cold is generated in the freezer compartment and then transferred to the refrigerator compartment. The adjustment occurs through a mechanical thermostat located inside the refrigeration chamber or on the body.
To adjust, find the thermostat knob. It usually has a scale from 1 to 7. The factory setting most often corresponds to position 3 or 4. If you have just placed the refrigerator in the kitchen, let it sit for 2-3 hours before turning it on, and then set the regulator to the middle position.
☑️ Setting a single-compressor refrigerator
If you notice that the food in the refrigerator compartment is freezing (for example, milk turns into ice near the wall), reduce the regulator value by one. If food spoils quickly or the chamber is too warm, increase the value. Remember that changing settings does not take effect instantly - the system requires time to stabilize the cycle.
⚠️ Attention: In single-compressor models, you cannot independently adjust the temperature in the freezer and refrigerator compartment. Increasing the cold in one compartment automatically increases it in the other. Make sure that in pursuit of cold in the freezer you do not overcool the main chamber.
Setting up two-compressor refrigerators and the No Frost system
Two-compressor models Atlant (for example, series 45 series or 60 series) are equipped with two independent cooling circuits. This allows you to set the temperature in each compartment separately without affecting the operation of the neighboring one. Such models often use electronic control panels or two separate mechanical regulators.
In models with a system No Frost it is important to understand the principle of air circulation. Cold air is pumped by a fan and distributed throughout the chamber through special channels. If you pack the shelves too tightly, blocking the outlet openings circulation will be disrupted, and the temperature sensor may not read the data correctly, causing the compressor to work longer than necessary.
Why can it be warmer at the door in No Frost?
B In systems with forced air circulation, the coldest flow is located at the rear wall, where the evaporators are located. Closer to the door, the temperature may be 2-3 degrees higher due to heat losses when opening and distance from the cold source. Do not store perishable food on the door or at the very edge of the shelves.
When setting the electronic display, use the Temp buttons or separate keys for the refrigerator and freezer compartments. The recommended value for the refrigerator compartment is +3...+4°C, for the freezer compartment - -18...-20°C. Lower temperatures in the freezer (-24°C) make sense only in the fast freezing (Super Freeze) mode, which must be turned off after use.
The influence of external factors and seasonal adjustment
The ambient temperature directly affects the operation of the refrigerator Atlant. In summer, when the kitchen is hot, heat exchange in the condenser (grid at the back) is difficult. The compressor has to work longer to release the heat. In winter, on the contrary, the load decreases.
If your refrigerator is located next to a stove, a radiator, or in direct sunlight, the standard settings may not be enough. In such cases, the unit will operate under increased load. It is recommended to rearrange the equipment or, if this is not possible, set the regulator to stronger cooling, but be prepared to increase electricity bills electricity.
In winter, if the refrigerator is in an unheated room (for example, on a balcony, which is not recommended for most models Atlant), oil in the compressor may thicken. This results in failure at startup. If the appliances are in a warm kitchen, in winter you can slightly reduce the cooling power, since heat inflows from outside are minimal.
Common errors and problem diagnosis
Often users are faced with a situation where a seemingly correctly set temperature does not give the expected result. One of the most common mistakes is overloading the chamber with warm products. If you put a three-liter pan of hot soup in the refrigerator, the temperature sensor will detect a sharp jump in heat and cause the motor to wear out until the soup cools down.
Another mistake is a violation of the tightness of the seals. If the rubber band on the door Atlant does not fit tightly, warm air constantly flows inside. In this case, no adjustment of the thermostat will help: the refrigerator will work continuously, becoming overgrown with a “coat” of ice. Check the seal by pressing a sheet of paper against it: if it is pulled out without force, the seal requires replacement or adjustment.
It is also worth mentioning the correct placement of the thermometer for checking. Do not place a household thermometer directly against a back wall or a fan. Place a glass of water on the middle shelf, lower the thermometer there and close the door. After a few hours, you will get the real temperature of the product, not the air.
⚠️ Attention: If you set the minimum temperature, but the food still spoils, or vice versa - freezes at minimum power, the problem may not be in the settings, but in a refrigerant leak or a malfunction of the thermostat. In this case, diagnostics by a specialist is necessary.
Frequently asked questions (FAQ)
Why does ice freeze in the Atlant refrigerator, even if I don’t open the door?
This can happen for several reasons: a loosely closed door (check the food to see if it’s in the way), damaged seal, or clogged drain hole. In models with a drip system, a small amount of ice on the rear wall while the compressor is operating is normal; it should drain when turned off.
What thermostat value should you choose to save energy?
For maximum savings, try to keep the regulator in a position corresponding to +4...+5°C in the main chamber (usually 2-3 divisions on the mechanics). Each additional division towards the maximum increases energy consumption by approximately 5-10%. It is also important to ensure that the refrigerator does not stand close to the wall.
Is it possible to store food in the refrigerator without packaging?
It is strictly not recommended. Products without packaging quickly weather, lose moisture and transfer odors to each other. In addition, open products can become a source of bacteria that will settle on the evaporator, which will lead to an unpleasant odor and disruption of the moisture removal system moisture removal systems.
What does the flashing temperature indicator on the display mean?
A flashing indicator usually indicates that the temperature in the chamber is above the set norm. This often happens immediately after switching on, after defrosting, or after loading a large amount of warm food. If the blinking does not stop during the day when the door is closed, the sensor or compressor may be faulty.
