Correct temperature setting is the foundation for the long service life of your refrigeration equipment and maintaining food freshness. For owners of Belarusian brand equipment Atlant this question is especially relevant, since mechanical thermostats require an understanding of the principles of their operation. An incorrectly set mode can lead to rapid spoilage of food or, conversely, to excessive consumption of electricity and the formation of excess ice.
In two-chamber models, the microclimate in the refrigerator compartment and freezer compartment is regulated differently, but interconnected. The main control is usually located inside the refrigerator compartment, and the freezer may be controlled by a separate knob or damper. Understanding exactly how your thermostat reacts to changes will help you avoid common operating mistakes.
In this article we will look in detail at what values are considered normal for various products, how to set up a mechanical regulator and what to do if the refrigerator stops keeping cold. You will learn why you cannot blindly rely on the numbers on the scale and how to check the real temperature inside the chambers using simple means.
Standard temperature operating conditions
For most models Atlant with a two-chamber system, there are average parameters that are considered ideal for everyday food storage. In the refrigerator compartment, the optimal range is considered to be from +2 to +5 degrees Celsius. It is under such conditions that pathogenic bacteria multiply slowest, and products retain their taste.
The freezer must provide deep freezing, so the standard requirement is to maintain a temperature no higher than -18 degrees. Some modern models allow you to lower this threshold to -24 degrees in super-freezing mode, but for permanent storage such cold is not required and is even harmful for some types of frozen semi-finished products.
It is important to understand that cold distribution there is unevenness inside the chambers. The shelves near the back wall are always colder than those near the door. Therefore, perishable foods such as meat or fish should be placed closer to the source of cold, and drinks or sauces should be placed on door shelves.
- 🌡️ The optimal zone for dairy products is on the middle shelves, where the temperature is stable.
- ❄️ Vegetables and fruits are best stored in the lower drawers, where the mode is most gentle.
- 🥩 Place raw meat and fish on the coldest shelf, usually the top one, closer to the back wall.
If you notice that condensation appears on the products or, conversely, they begin to freeze, this is a signal that you need to adjust the thermostat settings. Small changes in the position of the handle can significantly affect microclimate inside the chamber.
Setting the mechanical thermostat
In classic models Atlant control is carried out via a mechanical thermostat, often located inside the refrigerator compartment at the top right or under the lampshade. The scale of such a regulator is usually graduated with numbers from 1 to 7, where 1 is the minimum cold (maximum heat), and 7 is the maximum cooling.
Many users mistakenly believe that the number on the scale corresponds to degrees Celsius. This is wrong. The number indicates the intensity of the compressor. Setting the knob to position 7 forces the motor to work almost without stopping, which can lead to freezing of the evaporator. Position 1, on the contrary, turns on the compressor rarely, which is dangerous in the hot season.
The optimal position for year-round operation is considered to be the middle of the scale - values 3 or 4. In the summer, when the temperature in the kitchen is high, it makes sense to slightly increase the cooling by moving the knob towards higher values. In winter, when the room is cool, the load on the compressor can be reduced.
When first turning on or after defrosting, it is recommended to set the regulator to the middle position and let the refrigerator operate for several hours without loading food. This will allow the system to reach operating mode and stabilize the temperature background.
Adjusting the freezer compartment
In two-chamber refrigerators Atlant the freezer compartment often has its own cooling circuit or a separate regulator, especially in models with No Frost system or additional frost button. If your model has a separate handle for the freezer, it also works on the principle of intensity, rather than exact temperature.
For long-term storage of stocks of meat, fish and berries, the standard mode is sufficient. However, if you plan to prepare a large amount of fresh food, you should activate the super-freezingmode. In mechanical models, this is often done by moving the switch to the extreme position or by pressing a special button, which lights up with an indicator.
⚠️ Attention: Do not keep the super-freezing mode turned on continuously for more than 24 hours. This places excessive load on the compressor and can shorten the life of the refrigeration unit refrigeration unit.
After the food has frozen (usually after 24 hours), the regulator must be returned to the standard position. Constant operation at the limit of capacity does not make sense for already frozen products and only increases bills for electricity.
☑️ Checking the operation of the freezer
Pay attention to the condition of the ice in the freezer. If it has a white, cloudy tint, this may indicate a violation of the temperature regime or air entry during freezing. Transparent ice is a sign of proper and rapid freezing.
Seasonal features of operation
The ambient temperature directly affects the efficiency of the refrigerator. In the summer, when the apartment is hot, heat exchange from the condenser (the grille at the back) is difficult. In such conditions, the compressor has to work longer to maintain the set temperature regime temperature regime inside the chambers
In winter, the situation changes. If the refrigerator is in an unheated room or in the kitchen, where the temperature drops below +10 degrees, the oil in the compressor may thicken and the refrigerant may lose its properties. This is especially critical for single-compressor models Atlant.
| Season | Recommended regulator position | Features |
|---|---|---|
| Summer (+25°C and higher) | 4-5 (closer to the maximum) | Enhanced cooling to compensate for the heat |
| Off-season (+15...+20°C) | 3-4 (average) | Standard operating mode |
| Winter (in a heated room) | 2-3 (closer to the minimum) | Reducing the load on the compressor |
It is not recommended to place the refrigerator in close proximity to heating appliances or in direct sunlight. This creates a false sensation of overheating for the sensors or actually increases the temperature inside the chambers, causing the motor to wear out.
The influence of loading on temperature
A full refrigerator keeps the temperature more stable than an empty one. Products are essentially cold accumulators. If you just bought a new one Atlant or defrosted an old one, do not load it with food right away. Allow the chambers to cool to operating temperature when empty.
Loading hot or warm products is one of the most common causes of temperature failure. The evaporator becomes covered with a thick layer of frost, the temperature sensors (or the thermostat bellows) cannot read the readings correctly, and the compressor works without interruption. This leads to the formation of a “snow coat” and increased electricity consumption.
Air circulation also plays an important role. Don't overcrowd the shelves, leave gaps between products. Cold air should freely wash the contents of the chambers. In models with forced circulation (No Frost), blocking the ventilation holes with food is strictly prohibited.
The myth of a full load
There is an opinion that an empty refrigerator works more economically. In fact, the empty volume of air quickly heats up when the door is opened, and the compressor has to cool the entire volume again. Shelves filled with food keep it cold longer.
If you need to cool a large amount of food (for example, after a holiday), use the maximum cooling mode in advance, several hours before loading. This will create a supply of cold in the evaporator.
Diagnostics of temperature problems
Sometimes users are faced with a situation where the regulator is set to the desired value, but the food spoils or freezes. First of all, you should check the tightness of the door. If the rubber has dried out or become dirty, warm air enters the chamber and the refrigerator cannot gain temperature. sealing rubber doors. If the rubber becomes dry or dirty, warm air enters the chamber and the refrigerator cannot reach temperature.
The second common problem is a malfunction of the thermostat. If the refrigerator does not turn on at all or, on the contrary, works non-stop, not responding to turns of the handle, most likely the sensor has failed. In models Atlant this is a repairable unit, the replacement of which does not require calling a technician.
⚠️ Attention: If you hear clicks of the thermostat, but the compressor does not start, the problem may be in the starting relay or the motor itself. Prolonged operation in this mode is dangerous.
It is also worth checking the defrosting system. If the drainage hole in the refrigerator compartment is clogged, the water does not drain, freezes and blocks the cold supply channels. As a result, it may be warm in the chamber, but there may be a block of ice in the freezer.
Frequently asked questions (FAQ)
Why does ice freeze on the back wall in the Atlant refrigerator?
This is a normal process for a drip defrosting system. Water condenses on the back wall, freezes, and then flows into the drain when the compressor is turned off. If there is too much ice, check the position of the thermostat - perhaps it is set to maximum.
What temperature should you set in the summer if the apartment is +30 degrees?
In hot weather, it is recommended to move the thermostat knob towards higher values (4-5), but not to set it to maximum (7), so as not to overload the compressor. It is also important to ensure good ventilation around the refrigerator body.
What does a flashing temperature indicator on the display mean (if any)?
Flashing usually indicates that the temperature in the chamber has risen above the permissible norm. This may be due to the door being open for a long time, warm food being loaded, or a malfunction of the cooling system. If the indicator does not go out after a few hours, contact the service.
Is it possible to use the Atlant refrigerator on the balcony in winter?
Operation at temperatures below +10 degrees is not recommended by the manufacturer. The oil in the compressor thickens, which leads to failure when starting. If the balcony is insulated and it’s warm there, use is possible.
