Correctly setting up the freezer is not just a matter of comfort, and the need to maintain the quality of products and extend the service life of the compressor. Atlant refrigerators, which enjoy deserved popularity due to their reliability, require a careful approach to adjusting temperature conditions. Errors in setting parameters can lead to rapid deterioration of supplies or the formation of excessive ice.
Owners are often faced with a dilemma: set the maximum cold “just in case” or save energy. It is important to understand that mechanical thermostats electronic control panels operate on different principles. In this article, we will analyze the nuances of setting up for various series of equipment so that you can optimize the operation of your device.
Before taking active steps, it is worth assessing the current state of the camera. If the products do not freeze enough or, on the contrary, turn into “stone,” correction is required. The optimal temperature for long-term storage of meat and fish in the freezer is considered to be minus 18 degrees Celsius and below. It is this parameter that blocks the proliferation of bacteria and preserves the structure of the fibers.
Principles of operation of thermostats in different models
Understanding how your refrigerator “thinks” will help you avoid mistakes. Most classic models Atlant use a mechanical regulator. This is a simple but effective mechanism where turning the knob changes the force of pressure on the refrigerant valve. The higher the number on the scale, the more intense the compressor works.
Modern series, especially with the system No Frost, are often equipped with electronic control. Here the setting takes place through the display and buttons, where you set the exact numerical value of the temperature. The electronics independently control the operation of the fans and evaporator, minimizing differences.
It is worth considering that in two-compressor models, the freezer settings are completely independent of the refrigeration compartment. This has the advantage that you can freeze a large batch of food without affecting the storage mode of vegetables in the main chamber. In single-compressor units, changing the freezer mode indirectly affects the upper part.
Setting a mechanical thermostat
If on the front panel or inside the refrigerator compartment you see a round knob with numbers from 1 to 7 (or from Min to Max), then you have a mechanical model. There are no exact degrees here, only relative power levels. For normal operation in the summer, it is usually enough to set the regulator to position 3 or 4.
In winter, when the room temperature drops, the load on the system changes. If the room is colder than +16°C, the compressor may stop turning on during long cycles. In such cases, it may be necessary to force the switch on or set the regulator to maximum, but this is a temporary measure.
When turning on for the first time or after defrosting, it is recommended to set the knob to the middle value. Let the unit operate for several hours without loading food. If you notice that the ice is melting in the freezer, but it’s warm in the main chamber, turn the knob towards larger numbers.
⚠️ Attention: A sharp turn of the mechanical thermostat knob from minimum to maximum can lead to water hammer in the freon circulation system. Change the settings smoothly, at intervals of 15-20 minutes.
Temperature adjustment in models with electronic control
Owners of modern Atlantov with a display have the ability to see the exact temperature. Typically, to enter the setup mode, you need to press and hold the setup button (often indicated as Set or thermometer icon) for 3-5 seconds.
After activating the mode, the freezer indicator will begin to flash. Using the Up and Down buttons, set the desired value. The standard recommendation is -18°C. If you plan to load a lot of fresh food, you can activate the Super Freeze mode, which will temporarily lower the temperature to -24°C.
It is important to remember to turn off the intensive freezing mode in time. If you leave it on for several days, the compressor will wear out and the food may dry out. The electronics itself will turn off this mode after a certain time (usually 24-48 hours), but monitoring will not hurt.
The influence of seasonality and load on the operation of the refrigerator
External temperature directly affects the efficiency of heat transfer. In the summer, when the apartment is hot, it is more difficult for the refrigerator to transfer heat through the condenser (the grille at the back). During this period, it may be necessary to install the regulator 1 notch more powerful than in winter.
The degree of loading of the chambers also plays a role. An empty refrigerator cools down faster, but it also loses cold instantly when the door is opened. The products work as a cold accumulator. However, if the freezer is jam-packed, air circulation will be disrupted (especially in the systems No Frost), and the temperature will rise.
The optimal fill rate is about 70-80% of the total volume. There should be gaps between products for free circulation of air flow. If you have loaded a lot of warm food at once, use the fast freezing mode, but keep an eye on its operating time.
☑️ Checking the operating conditions
Table of recommended modes for different products
Different types of products require different storage conditions. Meat, fish, berries and ready-made dishes have their own nuances. Below is a table to help you navigate the settings for maximum preservation of benefits.
| Product type | Recommended temperature | Shelf life (approximate) | Features |
|---|---|---|---|
| Meat (beef, pork) | -18°C and below | 6-12 months | Requires quick freezing |
| Poultry | -18°C ... -20°C | 8-10 months | Sensitive to changes |
| Faty fish | -20°C ... -24°C | 3-6 months | Fat can oxidize |
| Vegetables and berries | -18°C | 8-12 months | Shock freezing is needed |
| Semi-finished products | -18°C | 3-6 months | Make sure the seal is tight |
Please note that the shelf life is indicated for products that have been frozen fresh and not subjected to repeated defrosting. Repeated freezing It is strictly not recommended, since ice crystals destroy the cellular structure, and the product loses its taste and beneficial properties.
Diagnosis of problems after adjustment
If you You have set the correct values, but the result does not meet expectations, it is worth checking the technical condition. Often the problem lies not in the settings, but in the tightness or condition of the seals. Check whether the freezer door fits tightly around the entire perimeter.
The formation of a thick “coat” of ice, even with correct settings, may indicate a malfunction of the defrost sensor or heating element (in No Frost models). If ice does not form at all, but the temperature does not hold, there may be a refrigerant leak.
Why does the refrigerator hum after adjustment?
An increase in hum after turning the regulator to maximum cold is normal. The compressor begins to work more intensively, creating more vibration and noise. If the sound is not a metallic clang, but a smooth hum, there is no need to worry.
⚠️ Attention: If, after setting the temperature, the motor-compressor runs non-stop for more than 12 hours without turning off, this is a malfunction signal. Prolonged operation at the limit can lead to burnout of the motor winding.
For accurate diagnostics, you can use an external thermometer. Place it between grocery bags in the center of the freezer and leave it for a few hours. Compare the readings with those you set on the regulator. The difference should not exceed 2-3 degrees.
Frequently asked questions (FAQ)
Is it possible to set the Atlant freezer to -25 degrees constantly?
Technically this is possible, but it is not economically feasible. At a temperature of -25°C, energy consumption increases significantly and the compressor life is reduced. For most products, -18°C is sufficient.
Why did more ice appear in the freezer after adjusting the temperature?
Most likely, you brought food at room temperature into the freezer or frequently opened the door. Humid air from the room condenses and freezes. Also check the tightness of the seal.
How to reset the electronics settings to factory settings?
Usually it is enough to unplug the refrigerator for 10-15 minutes. In some models with a display, the combination of reset buttons is described in the instructions (often this means pressing two buttons simultaneously).
Does setting the freezer affect the temperature in the refrigerator compartment?
In two-compressor models - no. In single-compressor systems (where there is one motor for both chambers) - yes, a change in power affects the overall operating cycle, but the distribution of cold is regulated by dampers or the proportion of work of the evaporators.
