Every owner of household appliances sooner or later is faced with the need to adjust the climate inside the chambers. Atlant refrigerators They are famous for their reliability, but for their effective operation, correct initial settings are required. The wrong choice of parameters can lead to rapid spoilage of food or the formation of excessive ice on the walls.
In this article we will look in detail at how to set the optimal values for different models, including systems with electronic control and mechanical thermostats. Understanding the principles of operation compressor and the system No Frost will help you extend the life of the unit. You will learn how to independently diagnose failures and correct the operation of the device without calling a specialist.
Principles of operation of the thermostat in different models
Climate control systems in the equipment of the Belarusian manufacturer are divided into two main types: mechanical and electronic. In models with mechanical control the user sees a rotary knob with numbers from 1 to 7 or from Min to Max. It is important to understand here that the numbers do not indicate degrees Celsius, but indicate the intensity of the compressor.
Electronic panels, often found in the series Atlant XM-4425 or XM-6025, allow you to set the exact temperature in steps of one degree. Digital sensor reads readings in real time and automatically turns off the motor when a preset threshold is reached. This provides a more stable microclimate and saves energy.
⚠️ Attention: When turning on a new refrigerator for the first time or after defrosting, do not try to immediately set the minimum temperature. Let the unit operate in standard mode for several hours so that the refrigerant is evenly distributed throughout the system.
Regardless of the type of control, the principle remains the same: the thermostat or electronic unit compares the current temperature with the set one. If the chamber is warmer than normal, the circuit closes and starts cooling. In models with one compressor, the cold first enters the freezer compartment and then into the refrigerator compartment, which creates a certain dependence of the settings.
Why does the thermostat click?
In mechanical models, a click when the compressor is turned on or off is the normal operation of the bimetallic strip inside the thermostat. It physically opens or closes contacts depending on the temperature. If the clicks become very loud or frequent, the part may need to be replaced.
Setting a mechanical thermostat
Owners of classic models, such as Atlant 4008 or 3398, need to focus on the regulator scale, usually located inside the refrigerator compartment. Turning the knob clockwise increases the cooling power. Value 3 or 4 is considered optimal for everyday use at standard room temperatures.
If you set the knob to maximum (number 7), the compressor will work almost without interruption. This may be required for quick freezing of a large volume of food, but in constant mode it will lead to overheating of the motor and freezing of the evaporator. At minimum (number 1), the unit may not cope with cooling in hot weather.
Seasonality plays an important role when choosing the position of the regulator. In the summer, when the apartment is hot, it makes sense to add power by moving the handle closer to maximum values. In winter, on the contrary, you can reduce the intensity of work to prevent excessive freezing of moisture from the products.
☑️ Checking the mechanical settings
Electronic display control
Modern series, for example Atlant XM-4625 or XM-6210, are equipped with convenient displays on the door. Here the setting temperature mode is made using touch buttons or arrow keys. The screen displays the current indicators for the refrigerator and freezer compartments separately.
To change the parameters, you usually need to press the chamber selection button, after which the corresponding numbers will begin to flash. Using the Up or Down arrows you set the desired value. Confirmation often occurs automatically a few seconds after the last press or manually with the button OK/Confirm.
| Camera | Optimal temperature | Super cooling mode | Economy mode |
|---|---|---|---|
| Refrigeration | +3...+5 °C | +2 °C | +6...+7 °C |
| Freezer | -18 °C | -24 °C | -15...-16 °C |
| Zero zone | 0...+1 °C | Not applicable | Not applicable |
The electronics also allow you to activate special functions such as “Vacation” or “Super Freeze”. The “Vacation” mode** increases the temperature in the refrigerator compartment to +15°C, preventing the appearance of mold during a long absence of the owners, but keeps the freezer in working condition. This is a useful function for saving electricity.
Optimal values for food storage
The correct temperature is the key to food safety. For the main compartment of the Atlant refrigerator, +3...+5 degrees Celsiusis considered the ideal range. Under such conditions, dairy products, meat and ready-made dishes remain fresh for as long as possible, without freezing or spoiling.
In the freezer, the standard value is -18 °C. It is this temperature that guarantees that bacteria will not multiply in the products, and their structure will not be destroyed during long-term storage. If you plan to store supplies for more than 3 months, it is better to reduce the value to -20 or -24 degrees.
- 🥩 Meat and fish: require stable cold, it is better to place them on the lower shelves closer to the back wall.
- 🥛 Dairy products: sensitive to changes, optimal storage on the middle shelves at +4 °C.
- 🥦 Vegetables and fruits: in the freshness zone (if available) or on the bottom shelf at +5...+7 °C.
- 🍺 Drinks: can be stored at a higher temperature, closer to the door, but not allowing heating above +10 °C.
It is important to consider that the temperature may differ in different areas of the same chamber. The back wall, where the cold air comes out, is always colder than the door. Therefore, perishable foods, such as raw meat or opened canned food, should be placed away from the entrance to the chamber.
⚠️ Attention: Do not fill the refrigerator with food immediately after purchase. Warm food will create a sudden temperature spike, causing the compressor to work harder. Allow food to cool to room temperature before loading.
Seasonal adjustments and external factors
Room temperature directly affects the operation of refrigeration equipment. If the kitchen is hot (+25 °C and above), heat exchange is disrupted and it is more difficult for the unit to gain cold. During such periods, the mechanical regulator should be turned a little stronger, and in electronic models you can temporarily turn on the intensive cooling mode.
In winter, the situation changes. If the refrigerator is in an unheated room or near a window, the surrounding air may be too cold. For some Atlant models, operation at temperatures below +10 °C is not recommended, since the oil in the compressor thickens, which can lead to breakdown.
It is also worth considering the frequency of door opening. In a large family, where the refrigerator is opened dozens of times a day, a lot of warm air enters. In this case, it makes sense to set the settings 1 degree lower than standard to compensate for heat transfer.
Diagnostics of temperature problems
If you notice that food has begun to deteriorate faster than usual or, conversely, to freeze in the main compartment, this is a signal of failure. A frequent problem is the formation of a snow coat on the back wall. This may indicate a loose door fit or a malfunction of the thermostat. snow coat on the back wall. This may indicate a loose door seal or a faulty thermostat.
In models with the system No Frost the absence of frost is the norm, but if ice appears there, it means that moisture removal is impaired or the fan is working. Check to see if the drainage holes are clogged with food crumbs. Regular cleaning the drainage helps to avoid many temperature problems.
- ❄️ Food freezes against the wall: move them away from the back panel where the cold stream comes out.
- 🔊 The compressor is constantly humming: Perhaps the temperature is set to maximum or there are too many warm foods in the chamber.
- 💧 Water on the floor: Check whether the condensate tray under the compressor has moved.
If after adjusting the settings and checking the seals the problem persists, you may need refilling with freon or replacing the sensor. In such cases, independent repairs can be dangerous, and it is better to contact a service center for diagnostics.
Why is there a different temperature in the Atlant refrigeration chamber?
This is a physical feature of the operation of any refrigerators. Cold air is heavier than warm air, so it sinks. In addition, the source of cold (evaporator) is usually located at the top or at the back wall. Therefore, it is always colder on the upper shelves and near the wall than on the door or in the lower drawers for vegetables.
Is it possible to set the temperature below -24 degrees all the time?
Technically it is possible, but it is not economically feasible. At extremely low temperatures, electricity consumption increases by 20-30%, but the nutritional value of products does not increase. The -24 °C mode is intended only for quick freezing of fresh food, after which the temperature should be returned to -18 °C.
What to do if the electronic display does not respond to pressing?
Some models have a child lock function (usually you need to hold down the button with the image of a lock for 3-5 seconds). If the lock is removed and the panel does not work, try turning off the power to the refrigerator for 10 minutes. If the problem persists, the control panel itself may be faulty.
