Reducing the temperature in the refrigerator or freezer Atlant is often required when the load on the cooling system sharply increases. This may be due to loading a large amount of fresh food, summer heat or changes in operating hours. Understanding the operating principles of thermostat and sensors is critical for the correct operation of equipment.
Owners are often faced with a situation when food stops freezing or, conversely, the cooling chamber turns into a glacier. Adjusting the parameters allows you to return optimal storage conditions. It is important to know that mechanical and electronic control systems require different approaches to setting.
Incorrect setting of values can lead to rapid deterioration of inventory or compressor breakdown due to continuous operation. Before interfering with the settings, you need to determine the control type of your model. This will help avoid mistakes and ensure energy saving during the operation of the unit.
Adjustment features in single-chamber models
Single-chamber refrigerators Atlant equipped with one thermostat that regulates operation compressor based on the evaporator temperature. Reducing the temperature in the main chamber is achieved by turning the regulator knob towards larger numbers. However, it is worth remembering that in such models temperature mode the freezing and refrigeration parts are interconnected.
When you turn the knob to the value “maximum” or “5” (depending on the model), the compressor will work almost without stopping. This will result in deep freezing, but will significantly increase electricity consumption. If the chamber is too cold and the knob is already at minimum, the thermostat itself may be faulty or there may be a refrigerant leak.
⚠️ Attention: In single-chamber models, the cold in the freezer and refrigerator compartment cannot be independently adjusted. Setting the maximum mode can lead to freezing of vegetables at the bottom.
For precise settings, it is recommended to use a household thermometer placed in a glass of water on the middle shelf. This will allow you to objectively assess real temperature inside the chamber, and not rely only on sensations or numbers on the regulator.
Setting up two-chamber refrigerators with mechanical control
Two-chamber models with mechanical control usually use one thermostat located in the refrigeration chamber. It controls the air temperature in the upper compartment, and the freezer is cooled according to the residual principle. To reduce the temperature, you need to turn the regulator knob clockwise.
The values on the scale from 1 to 7 (or Min/Max) do not correspond to degrees Celsius, but indicate the intensity of the compressor. Setting the value to maximum will cause the unit to run continuously. This is permissible in the mode super freezing, but not for constant use.
- 🌡️ For normal storage of products, it is recommended to set the knob to position 3 or 4.
- ❄️ Use the “Super” mode or the maximum value only when full load of fresh products.
- ⚙️ If the compressor does not turn off for more than 12 hours when set to minimum, check the tightness of the seals.
It is important to consider that in models with one compressor changing the settings in the refrigerator compartment will immediately affect the freezer. If the freezer is not cold enough, and the refrigerator is already at the “north pole”, the problem may not be in the settings, but in the defrost system or the amount of refrigerant.
Temperature control in models with an electronic controller
Refrigerators Atlant with electronic control (XM, KHT series and others) allow you to set the exact temperature for each chamber regardless. The control panel usually contains display and adjustment buttons. To change parameters, you often need to press and hold the setting button for several seconds until the flashing indicators appear.
Reducing the temperature in the refrigerator compartment is done using the "up" or "down" arrow buttons after activating the setting mode. The optimal value for food safety is considered to be a range from +3 to +5 degrees Celsius. In the freezer, it is recommended to set the value to -18°C.
Electronics are more sensitive to power surges, so if the network fails, the settings may be reset to factory settings. In this case temperature adjustment you will have to do it again. Some models are equipped with a panel lock function that must be disabled before making changes.
| Parameter | Recommended value | Acceptable range | Impact on products |
|---|---|---|---|
| Refrigerator compartment | +4°C | +2...+5°C | Optimal for dairy and meat products |
| Freezer compartment | -18°C | -16...-24°C | Guarantees long-term storage without loss of properties |
| Freshness zone | 0°C | -1...+1°C | Ideal for vegetables, fish and meat for 1-2 days |
| Super mode | On (temporarily) | Automatic shutdown | Quick freezing of large volumes |
⚠️ Attention: When setting up the electronic control unit, avoid frequently pressing buttons without pauses. This can lead to the controller freezing and the need to completely disconnect the device from the network.
What to do if the display does not respond?
If the control panel is locked, find the button with the image of a lock or key. Hold it for 3-5 seconds until a beep appears or the screen unlocks. Some models require pressing two buttons simultaneously.
Using the super freeze mode and its effect
The function superfreezing (Super Freeze) is designed to quickly lower the temperature in the freezer to extreme values (usually -24°C and below). In refrigerators Atlant this mode is often activated by a separate button or by turning the knob to the red zone.
When this function is activated, the compressor runs non-stop, ignoring standard shutdown cycles. This allows you to quickly freeze fresh food, preserving its structure and nutrients. However, prolonged use of the mode leads to hypercooling already frozen stocks and increased wear of the motor.
In models with mechanical control, the super-freezing mode often does not have an automatic shutdown. The user must return the regulator to its operating position after 24–48 hours. Forgetfulness in this matter is fraught with icing of the evaporator and difficulties with opening doors.
- 🕒 Turn on the super freezing mode 4-6 hours before loading a large batch of products.
- 🛑 Do not keep the function active for more than 3 days unless absolutely necessary.
- 🔌 In mechanical models, be sure to turn off the mode manually after freezing is complete.
Use intensive cooling is justified when preparing for a long absence or after defrosting. Under normal conditions of daily use, standard thermostat settings are sufficient.
☑️ Check after turning on super freezing
Factors affecting cooling efficiency
Even with the correct settings temperature inside may remain high due to external factors. One of the main enemies of efficiency is the location of the refrigerator. If Atlant stands close to the wall or in a niche, the air circulation around condenser (grids at the back) is disrupted.
Dense loading of cameras also plays a role. The refrigerator works more efficiently when it is full, since food serves as a cold accumulator. However, if the shelves are packed to capacity, blocking the vents, cold air will not be able to circulate. This will lead to the appearance of “warm zones.”
Frequent opening of doors during the hot season significantly increases the load on the system. Warm, humid air, getting inside, condenses and requires additional energy for cooling. Tightness of seals is a key factor in temperature stability.
⚠️ Attention: Do not put hot or warm foods in the refrigerator. This will not only increase the overall temperature, but will also cause the compressor to wear out, which can shorten its service life.
Seasonality also makes its own adjustments. In summer, the ambient temperature (room temperature) is higher, so the refrigerator takes longer to cool down. During such periods, a slight adjustment of the regulator may be required in the direction of increasing cold.
Diagnostics: when the settings do not help
If you have set the temperature to the minimum values, but the food still spoils or does not freeze, the problem may be technical. Often the culprit is thermostatwhich has stopped transmitting the correct signals to the compressor. In this case, replacing the regulator solves the problem.
Another common cause is a freon leak. If there is a lack of refrigerant, the compressor may hum continuously, but there will be no cold in any of the chambers. It is also worth checking the system defrosting: if the evaporator is overgrown with ice (“fur coat”), the cold simply does not enter the chamber.
In models with No Frost, a malfunction of the defrost fan or heating element will stop the circulation of cold air. In such cases, a simple temperature adjustment will not help, you will need to call a technician to troubleshoot the components.
- 🔊 Loud knocking or clicking during operation may indicate problems with the start relay.
- 💧 Puddles under the refrigerator often indicate about a clogged drainage channel.
- ❄️ A “snow coat” on only one wall is a sign of a malfunction of the No Frost system.
Timely diagnostics allows you to avoid a complete replacement of the compressor. If the refrigerator Atlant stops freezing even at maximum settings, you should not delay contacting service.
How to check the thermostat yourself?
You can carefully remove the regulator handle and twist the rod. If when turning there is no characteristic click and no change in the sound of the engine, the thermostat is probably faulty. However, for accurate diagnosis you need a multimeter.
Why doesn’t the temperature in the Atlant refrigerator drop even at minimum?
If the regulator is turned to maximum and the temperature does not drop, most likely there is a refrigerant leak or the compressor has failed. It is also possible that the valve in the freon circulation system gets stuck. Professional diagnostics with a pressure gauge are required.
How often do you need to defrost the Atlant refrigerator for normal operation?
Models with manual defrosting require unplugging and defrosting at least once every 6 months. The accumulation of ice on the evaporator acts as a heat insulator, interfering with the cooling of products and causing the compressor to work longer.
Is it possible to install an Atlant refrigerator near the battery?
It is strictly not recommended. The proximity of heating devices disrupts the heat exchange of the condenser. The compressor will work with overload, trying to compensate for external heating, which will lead to rapid failure and excessive consumption of electricity.
What does a flashing temperature indicator on the panel mean?
A flashing indicator usually indicates that the temperature in the chamber is above the set norm. This may happen immediately after switching on, after loading warm food, or when the door is not tightly closed. If the blinking does not stop,
