Correctly setting the temperature in the refrigerator is not just a matter of comfort, but a key factor influencing the safety of food and the service life of the unit itself. For equipment owners Atlant this issue is especially acute, since many models are equipped with mechanical regulators that do not have a digital display, which often causes confusion among users. Incorrectly set parameters can lead to rapid spoilage of food, the appearance of ice, or, conversely, to over-drying of food.
In this article we will analyze in detail how to find the “golden mean” for the operation of your refrigerator, taking into account seasonal changes and the type of loaded products. Understanding the operating principles of thermostat will help you avoid common mistakes that many owners make during initial installation or after defrosting.
It is worth noting that there is no ideal value for all situations, however, there are basic standards established by the manufacturer and sanitary standards. We will look at the difference between the settings for the refrigerator and freezer compartments, and also find out what the numbers on the adjustment knob mean.
How the temperature regulator works in Atlant refrigerators
Most models of the Belarusian brand, especially the classic series, are equipped with a mechanical thermostat. This is a reliable device that closes and opens an electrical circuit depending on the temperature inside the chamber. On the front panel of the refrigerator or inside it (depending on the model) there is a knob with divisions, usually from 1 to 7 or from Min to Max. It is important to understand: the number does not mean degrees Celsius.
The higher the value you set on the regulator, the more intense it works compressor and the lower the temperature inside the chamber drops. That is, position “7” or “Max” is the maximum cooling mode, and “1” or “Min” is the minimum. Many users mistakenly believe that a large number means a higher temperature, which leads to spoilage of products.
Inside the housing there is a sensitive element - a bellows filled with gas or liquid. When the air in the chamber is heated, the gas expands and presses on the membrane, closing the contacts and starting the motor. When the desired temperature is reached, the pressure drops and the cycle stops. It is on the calibration of this mechanism that the climate will be maintained accurately Never try to forcibly turn the control knob beyond the extreme divisions. The mechanical limiter exists for a reason - excessive force can break the plastic rod or damage the internal spring of the thermostat, which will lead to the need to replace the part. inside your refrigerator.
⚠️ Attention: Never try to forcefully turn the knob beyond the outermost divisions. The mechanical limiter is there for a reason - excessive force can break the plastic rod or damage the internal thermostat spring, resulting in the need to replace the part.
There are also models with electronic control, where the temperature is set with an accuracy of a degree. In such cases The optimal value for the refrigerator compartment is +4°C, which is confirmed by numerous tests and recommendations of plant engineers. However, mechanics requires a more subtle approach and understanding of indirect signs.
Optimal values for the refrigerator and freezer compartments
To ensure long-term storage of products, it is necessary to maintain a stable temperature background. In the refrigerator compartment, where we keep ready-made meals, milk and vegetables, the temperature should range from +2 to +6 degrees Celsius. In the freezer, the standard is -18 degrees and below. These indicators ensure that bacteria will not multiply and the structure of the products will not be disrupted.
If you have a two-chamber refrigerator Atlant with one compressor, the setting is made according to the main (refrigeration) chamber. The freezer compartment in such models works in tandem, and the temperature in it depends on how long the compressor worked to cool the upper compartment. Therefore, it is important to avoid situations where the refrigerator is “warm”, but the freezer is already “freezing.”
For a mechanical regulator with a scale from 1 to 7, the “gold standard” under normal conditions is position 3 or 4. This value ensures a balance between energy consumption and cooling quality. Lower values (1-2) may not be sufficient in the summer, and high ones (6-7) will make the motor work almost without stopping.
In the freezer, if it is equipped with a separate regulator (in some No Frost models), the value should be set according to the instructions, but usually this is the middle of the scale. When loading a large amount of fresh food for freezing, you can temporarily turn on the “Super Freeze” mode, if it is provided by the design, but do not forget to turn it off after 24 hours.
Seasonal adjustment of settings: summer and winter
The environment has a direct impact on the operation of refrigeration equipment. In summer, when the temperature in the kitchen can reach +25..+30 degrees, heat exchange between the outer walls of the refrigerator and the air is difficult. The compressor takes longer to remove heat from the chambers. During this period, it is recommended to shift the regulator towards lower temperatures (large numbers), for example, by 4 or 5.
In winter the situation is the opposite. If the refrigerator is in a cool room, it requires less effort to keep it cold. However, here lies an important nuance for models with drip system defrosting. If the room is too cold (below +10..+12 degrees), the thermostat may simply not turn on, believing that it is already cold enough inside. This leads to defrosting of the freezer.
In some older models Atlant there was a special winter switch or recommendation for use. Modern models, as a rule, are designed to work in climate class SN (subnormal) up to +10 degrees, but it’s better not to take risks. If the kitchen is not heated, the refrigerator may require setting the thermostat to the minimum value or even turning it off if the temperature drops below the permissible limit.
It is also worth considering air humidity. In wet weather, condensation can form on the interior walls if the temperature is set too low relative to the dew point in the room. Adjusting the mode helps to minimize this effect.
Deciphering the numerical designations on the thermostat
To avoid confusion, let's systematize the data. On the control panel of refrigerators Atlant the most common scale is from 1 to 7. Understanding what is hidden behind each number will help you fine-tune the device to your needs. Below is a table of correspondence between the handle position and the approximate temperature conditions.
| Handle position | Operating mode | Approximate t° inside | When to use |
|---|---|---|---|
| 1 (Min) | Minimum cooling | +8..+10°C | Fruit storage, short-term storage, warm room |
| 2-3 | Economical / Standard | +5..+7°C | Everyday use, partial load |
| 4 | Optimal | +3..+5°C | Normal load, standard kitchen conditions |
| 5-6 | Intense | +1..+3°C | Summer heat, full load, storing meat/fish |
| 7 (Max) | Freezing / Super-cooling | 0..+2°C | Only for quick freezing (not more than 24 hours) |
As can be seen from the table, position 4 is the most universal. However, if you plan to store a lot of meat products or prepare supplies for the week, it is better to move the regulator to 5. For storing vegetables and fruits that do not like extreme cold (for example, some varieties of apples or potatoes, although it is better to store them separately), position 2-3 is suitable.
The exact temperature depends on the serviceability of the seals, the amount of food and the temperature in the room. Therefore, the numbers on the regulator are more of an indicator of the power of the compressor than an accurate thermometer.
How to check the temperature inside the refrigerator
You should not trust only sensations “by eye” or “by touch”, since the human body does not feel well the difference of a couple of degrees. To make sure that the selected mode is correct, it is best to use an external thermometer. This is a simple household appliance that can be placed on the middle shelf.
The testing procedure is quite simple, but requires patience. Place the thermometer in a glass of water (so that the inertia of measurement is higher) and place it on the middle shelf of the refrigerator, away from the walls and door. Leave the refrigerator alone for at least 6-8 hours without opening the door during this time. Only after this can you take readings.
☑️ Checking the temperature
If the thermometer shows a value above +6 degrees, it is necessary to increase the cooling power (turn the knob to a higher value). If the temperature drops below +2 degrees and the food begins to freeze, the regulator needs to be loosened. Repeat the procedure until you achieve a stable result around +4°C.
Also pay attention to the distribution of cold. It is always colder near the walls than in the center. Therefore, it is better to place perishable products (meat, fish, open dairy products) closer to the back wall or on lower shelves, and vegetables and fruits in special drawers or on the top shelves, where the temperature is slightly higher.
Typical errors when setting the mode
One of the most common mistakes is setting the regulator to maximum immediately after purchase or defrosting. Users want to cool food faster and set the knob to 7. This leads to the compressor working hard, trying to achieve a balance that is unattainable in this mode, and the products on the lower shelves freeze into ice.
The other extreme is ignoring the filling of the chambers. An empty refrigerator and a completely full one require different settings. Air cools faster than dense foods. If you have loaded the refrigerator completely with warm food, it makes sense to temporarily increase the mode, but then be sure to return the regulator to the normal position. Constant operation at maximum reduces the life of the engine.
⚠️ Attention: Do not put hot or warm foods in the refrigerator. This will not only disrupt the temperature regime for all other products, but will also force the thermostat to work in emergency mode, which can lead to the formation of a large “coat” of ice on the evaporator.
Another mistake is frequent twisting of the handle. The thermostat needs time (from 30 minutes to several hours) to stabilize the system. If you turn the knob in the morning, you shouldn’t turn it again in the afternoon if it seems to you that “it’s not getting colder.” Give the system time to react.
Why does the thermostat click?
The characteristic click when turning the refrigerator on or off is the sound of the thermostat contacts opening or closing. If the clicks become too frequent or, on the contrary, disappear when the compressor starts, this may indicate a malfunction of the temperature sensor.
Signs of incorrect mode settings
How to understand that you made a mistake in choosing the mode without using a thermometer? The system itself will give signals. If water constantly collects on the inner walls of the refrigerator compartment, which does not have time to drain into the drainage hole, or the products are covered with condensation, the temperature is probably too high for the current load, or air circulation is impaired.
On the other hand, if the vegetables in the boxes become limp and lose color, and the milk on the shelf closer to the wall is covered with an ice crust, you have gone too far with refrigeration. In this case, the regulator must be turned towards lower values. Also, a sign of excessive cooling may be frequent turning on of the compressor for short periods of time.
Pay attention to the operation of the No Frost system (if it has one). If the mode is incorrect, defrosting problems may occur and ice will begin to build up in the freezer, blocking the ventilation holes. This will cause the refrigerator compartment to become warm, even if the compressor is humming constantly.
Regular monitoring of the condition of the products and the internal space of the refrigerator will help you quickly adjust the settings and extend life your Atlanta.
Frequently asked questions (FAQ)
What to do if the control knob spins endlessly?
If the thermostat knob scrolls without characteristic stop clicks or without a feeling of resistance at the ends of the scale, this may indicate for mechanism failure. In normal condition, the Min and Max positions in which the handle locks should be clearly defined. In this case, the thermostat needs to be replaced.
Is it possible to keep the refrigerator on mode 7 all the time?
It is strictly not recommended. Mode 7 (Max) is designed for fast freezing or emergency cooling. Constant operation in this mode leads to overheating of the compressor, increased energy consumption and the risk of defrosting food in the refrigerator compartment due to freezing of the cold supply channels.
Why does ice freeze on the back wall in the Atlant refrigerator?
In models with a drip system, this is normal during the cooling cycle. The ice should melt when the compressor rests. If the ice does not melt, the temperature may be set too low, the drain hole is clogged, or the defrost heating element is faulty (in No Frost models). Check the position of the regulator.
How to switch the Atlant refrigerator to vacation mode?
In most mechanical models there is no separate “Vacation” mode. It is enough to simply empty the refrigerator compartment of perishable products, wash it, leave the door ajar (if the design allows, so that mold does not appear) and unplug it. Some modern models have a “Vacation” button, which turns off the refrigerator compartment, leaving the freezer to work.
Does the amount of food in the refrigerator affect the choice of mode?
Yes, directly. An empty refrigerator cools faster, and the thermostat can turn off the compressor earlier, preventing the freezer from freezing (in single-compressor models). A fully loaded refrigerator requires a more intensive mode (closer to 4-5), since the products have a large thermal capacity and slowly release heat.
