Modern refrigerators Polaris require a competent approach to setting the temperature regime in order to ensure long-term storage of food and economical energy consumption. Incorrect settings can lead to rapid spoilage of food or the formation of excessive ice on the walls of the chamber. Owners often have to understand the intricacies of the electronic control unit or mechanical regulators in order to find the optimal balance.
In this article we will analyze in detail the action algorithms for various series of Polaris refrigeration equipment, including models with the system No Frost and static cooling. You will learn how to avoid common mistakes during initial launch and seasonal reconfiguration. Understanding the principles of operation of the compressor and sensors will help you extend the life of your household appliances.
Adjusting the climate inside the chamber is not just turning a knob or pressing buttons, but a complex process that depends on the load of products and the temperature in the room. If you've just purchased your unit or are experiencing problems with it not freezing properly, this will be a helpful guide. We will look at the nuances that are rarely written about in brief instructions.
Features of temperature control in different Polaris models
The brand's refrigeration equipment Polaris is divided into two main groups according to the type of control: electronic and mechanical. In models with an electronic display, such as series RF or QR, settings are carried out via the touch panel located on the front door. Here the user sees precise digital values, which allows you to control the microclimate with an accuracy of a degree.
Mechanical models, often indicated by an index O or S in the name, use a rotary regulator inside the fridge compartment. This is a classic solution, where the position of the knob from 1 to 7 does not correspond to specific degrees, but only sets the intensity of the compressor. It is important to understandthat in such systems the number 1 means minimum cooling, and 7 - maximum, which often causes confusion among inexperienced users.
⚠️ Please note: There is no fixed Celsius scale for models with a mechanical regulator. Trying to set the "average" value may lead to different results depending on the temperature in the room and the density of the shelves.
Electronic control systems allow you to set separate parameters for the freezer and refrigerator compartments independently of each other. This is especially true for devices with two compressors or a complex air circulation system. Mechanical models most often have one common thermostat that regulates the operation of the unit as a whole, which makes them simpler, but less flexible in operation.
Instructions for models with an electronic display
If your door Polaris has an LED screen, the setup process begins with unlocking the control panel. Manufacturers specifically implement a child lock function, so simply pressing the buttons may not produce results. Typically, to activate the setting mode, you need to hold the button with the image of a lock for 3-5 seconds until a characteristic sound signal appears.
After unlocking, select the camera whose temperature you want to change. The standard factory setting for the refrigerator compartment is +4°C, and for the freezer -18°C. To change the value, use the arrow buttons or touch the + and -symbols. Do not forget to confirm the selection if the system does not do so automatically after a few seconds of inactivity.

Available in some advanced models function Super Freeze or “Super Freeze”, which forcibly turns on the compressor at maximum power. This mode is useful when loading a large amount of fresh food, but it is not recommended to keep it activated constantly, as this leads to increased wear of parts and increased electricity consumption.
⚠️ Attention: When the fast freezing mode is activated, the corresponding indicator may flash on the display. Do not turn off the device from the network at this moment to avoid malfunction of the electronic module.
☑️ Checking the display settings
Setting the mechanical thermostat
Owners of refrigerators Polaris with mechanical control need to focus on the position of the handle thermostat, which is usually located inside the main chamber, often next to the light bulb or on the ceiling of the compartment. The regulator scale, as a rule, has divisions from 0 to 7 or from Min to Max. The optimal position for most everyday situations is considered to be the middle of the scale - values 3 or 4.
If you notice that the food in the refrigerator begins to freeze at the back wall, you should turn the knob towards lower values. Conversely, if the milk quickly sours, and the chamber is clearly warm, it is necessary to increase the cooling intensity by moving the regulator towards higher numbers. Remember that changing the position of the knob does not give an instant result - temperature stabilization takes from 2 to 6 hours.
It is worth noting that mechanical thermostats are sensitive to ambient temperature. In winter, when the apartment is cool, the compressor may turn on less often, so it makes sense to slightly increase the cooling power. In the summer, in the heat, the load on the unit increases, and it is recommended not to set the regulator to maximum unless absolutely necessary, so as not to overload the motor.
What do the numbers on the mechanical regulator mean?
The numbers on the thermostat do not show degrees Celsius. They indicate the tension of the spring inside the valve. Number 1 is the minimum tension (weak cooling), number 7 is the maximum tension (the unit works almost without interruption).
Optimal temperature conditions for storage
To maintain food freshness and prevent the growth of bacteria, it is important to maintain strictly defined temperature parameters in different zones of the refrigerator. There is no universal value for all shelves, since in modern models Polaris with the system No Frost air circulation can create small temperature gradients.
Below is a table of recommended settings for different types of products. Compliance with these parameters will maximize the shelf life of food without losing its taste and vitamin composition. deviations from these standards even by 2-3 degrees can significantly reduce storage time.
| Product type | Recommended temperature | Storage area | Shelf life (approximate) |
|---|---|---|---|
| Fresh meat and poultry | from 0°C to +2°C | Zero zone / Meat and fish | 1-3 days |
| Dairy products | from +2°C to +4°C | Middle shelves | 3-7 days |
| Vegetables and fruits | from +4°C to +6°C | Bottom drawers | 5-10 days |
| Ready meals | from +2°C to +5°C | Top shelves | 1-2 days |
| Frozen products | below -18°C | Freezer compartment | up to 12 months |
Particular attention should be paid to the so-called “zero zone” or Fresh Zone compartment, if it is provided in your model Polaris. This compartment is kept at a temperature close to 0°C and the humidity is frequently adjusted. This is an ideal place for storing chilled meats, fish and cheeses, which quickly spoil at higher temperatures and lose their structure when frozen.
Seasonal adjustment and external factors
The temperature in the room where the refrigerator is installed directly affects the efficiency of its operation. The instructions for the equipment Polaris indicate operation in the climate class SN-T, which means normal operation at ambient temperatures from +10°C to +38°C. However, within this range, adjustments to the settings may be required.
In the summer, when the temperature in the kitchen rises, heat transfer from the condenser is difficult. The compressor takes longer to reach the set parameters. At this time, it is not recommended to set the minimum temperature in the chamber, as the unit will wear out. It is better to ensure good ventilation around the case and, if necessary, increase the temperature inside by 1 degree.
In winter, the situation may be the opposite, especially if the refrigerator is in an unheated room or near a window. At temperatures below +10°C, the oil in the compressor may thicken and the refrigerant may no longer evaporate effectively. In such conditions, mechanical thermostats may not turn on the motor at all, which will lead to defrosting of food.
⚠️ Attention: Installing the refrigerator next to heating appliances, a gas stove or in direct sunlight is strictly not recommended. This upsets the thermal balance and causes the electronics or thermostat to operate in an incorrect mode.
Diagnostics of problems with temperature conditions
Sometimes the user is faced with a situation where the seemingly correct setting does not bring results: the chamber is too warm or, conversely, everything freezes. Before calling a specialist, it is worth conducting an initial diagnosis. A common cause is not a malfunction, but a violation of operating rules or simple overload.
Check the tightness of the door and the condition of the sealing rubber. If warm air constantly enters the chamber, no regulator will be able to compensate for heat loss. Also make sure that the ventilation holes inside the chamber (especially in models No Frost) are not blocked by food. Blocked air circulation leads to local overheating or hypothermia.
- 🔍 Check whether the door to the housing is frozen due to ice.
- 📦 Make sure that the products are not lying close to the back wall.
- ❄️ Check freezer evaporator for excessive icing.
- 🔌 Make sure the voltage in the network is stable, surges can affect the operation of the electronics.
If after checking all the parameters and re-adjusting according to the instructions the situation has not improved within 24 hours, the temperature sensor, thermostat may have failed, or a refrigerant leak has occurred. In models Polaris with electronics, this can be signaled by a flashing temperature indicator or an audible alarm.
Why does the temperature alarm indicator light up?
A red flashing indicator (often an exclamation mark or the letter A) indicates that the temperature in the chamber has risen above normal. This may be caused by opening the door for a long time, loading hot food, or a malfunction of the cooling system. If the indicator does not go off after closing the door and stabilizing the mode, diagnostics are required.
Frequently asked questions (FAQ)
What value should be set on the mechanical regulator in the summer?
In the hot season, when the room temperature exceeds +25°C, it is recommended to set the regulator to values 2-3. This will prevent excessive load on the compressor. If you set it to maximum (6-7), the motor will work almost without stopping, which can lead to overheating and breakdown.
Why does ice freeze in the Polaris refrigerator, although it is set to No Frost?
The system No Frost prevents the formation of ice only if there is free air circulation. If you tightly packed the shelves with products or blocked the ventilation holes on the back wall, moist air will not flow to the evaporator, and condensation will begin to freeze on the products and the walls of the chamber.
How long will it take for the temperature to stabilize after setting?
After changing the thermostat settings or initially turning on the refrigerator Polaris it takes from 2 to 6 hours to reach the specified mode. During this period, it is not recommended to load the chamber with food and frequently open the door. The exact time depends on the volume of the chamber and the temperature in the room.
Is it possible to store medications in a Polaris refrigerator?
You can store medications in a household refrigerator only if the instructions for the drug allow a temperature range of +2...+8°C. However, it should be taken into account that in household models short-term temperature fluctuations are possible when the door is opened. For particularly sensitive drugs, it is better to use special thermal containers.
