Refrigerators Polair are known for their reliability and energy efficiency, but even the most modern equipment requires proper configuration. Incorrectly set temperature leads to overfreezing of food, ice formation, or, conversely, insufficient cooling. As a result, not only the quality of storage suffers, but also the service life of the compressor.
In this article you will find detailed instructionshow to adjust the refrigerator Polair depending on the model, time of year and workload of the chambers. We will analyze the optimal modes for the freezer and refrigerator compartments, explain how to use mechanical and electronic control panels, and also give tips on diagnosing typical problems.
If your refrigerator Polair is unstable - it turns on noisily, does not freeze or cover well frost - in 80% of cases, incorrect settings are to blame. You can fix this yourself, without resorting to the help of a specialist.
Optimal temperature conditions for Polair refrigerators
The manufacturer recommends maintaining a temperature of refrigerator compartment from +2°C to +5°C, and in freezer - from −18°C to −24°C. However, these values may vary depending on several factors:
- 📅 Time of year: in summer at high room temperatures the refrigerator works more intensively, so you can reduce the indicator by 1-2 degrees.
- 🍗 Camera load: if the refrigerator is full of food, especially hot ones, a lower temperature will be required for uniform cooling.
- ⚡ Energy consumption class: models Polair with an inverter compressor (Inverter) reach the set parameters faster and turn on less often.
For most modern models (Polair PCD-100, PCD-140, PCD-180 etc.), the optimal mode is considered:
- 🧊 Freezer compartment: −18°C (enough for long-term storage of meat, fish, semi-finished products).
- 🥦 Refrigerator compartment: +4°C (ideal for vegetables, dairy products, eggs).
If in yours model has a freshness zone (Fresh Zone), its temperature is usually 0°C - this allows you to preserve greens, fruits and cheeses longer without freezing.
Mechanical adjustment: how to use the thermostat
Most budget models Polair (for example, PCD-85, PCD-90) are equipped mechanical thermostat —a round switch with numbers from 1 to 7 (sometimes up to 9). The higher the number, the colder it is in the chamber. However, there are nuances here:
- ❄️ Position 1–2: minimal cooling (suitable for winter or if the refrigerator is almost empty).
- ⚖️ Position 3–4: optimal mode for most conditions (temperature in the refrigerator compartment ~+4°C).
- 🔥 Position 5–7: maximum cooling (needed in summer or when fully loaded).
To change the settings:
- Find the regulator - usually it is located inside the refrigerator compartment on the right wall or on top.
- Turn the knob clockwise to increase the cold, counterclockwise to decrease it.
- Wait 6-12 hours for the temperature to stabilize, then check with a thermometer.

Use a separate thermometer for an accurate check-->
Important: In models with one compressor (Polair PCD-100W) temperature control in the freezer and refrigerator compartments is interconnected. If you make the freezer colder, the refrigerator compartment will also cool by 1-2 degrees.
⚠️ Attention: If, after changing the settings, the refrigerator runs without stopping for more than a day, this may indicate thermostat malfunction or a freon leak. In this case, diagnostics of the master is required.
Electronic control: setting via display
Premium models Polair (PCD-180I, PCD-220I) are equipped touch panel or LED display, which simplifies adjustment. The interface may differ, but the general principle is the same:
To change the temperature:
- Press the button
Temp(orFridgefor refrigeration cameraFreezerfor the freezer). - Use the buttons
+/−set the desired value (steps are usually 1°C). - Confirm the selection with the button
OKor wait for automatic saving (3–5 seconds).
Some models support additional functions:
- 🌙 Vacation mode (Holiday): increases the temperature to +12°C, saving energy during long periods of absence.
- ❄️ Quick freezing (Super Freeze): temporarily reduces the temperature to −24°C for quick freezing of large volumes products.
- 🔄 Automatic defrosting (No Frost): disables the need for manual ice removal.
The display may show:
- 🔋 Energy consumption indicator (green/yellow/red).
- ⚠️ Alarm (if the door is open or the temperature is outside the normal range).
What to do if the display flashes or shows error?
If an error code appears on the screen (for example, E1, E2), this may mean:
- E1 — a problem with the refrigerator compartment temperature sensor.
- E2 — a malfunction of the freezer sensor.
- E3 — malfunction fan (for models with No Frost).
Actions:
1. Unplug the refrigerator from the outlet for 10-15 minutes, then turn it on again.
2. If the error repeats, contact a service center - independent repair of electronic boards can cause damage.
| Polair model | Control type | fridge compartment adjustment range | Freezer chamber adjustment range |
|---|---|---|---|
| PCD-85 | Mechanical | +2°C – +8°C | −12°C – −24°C |
| PCD-140 | Mechanical | +1°C – +7°C | −14°C – −26°C |
| PCD-180I | Electronic | +1°C – +9°C (1°C step) | −16°C – −24°C (1°C step) |
| PCD-220NF | Electronic + No Frost | 0°C – +8°C | −18°C – −26°C |
How to check the accuracy of the settings: tools and methods
Even if you have set the recommended values, the actual temperature may differ. This is due to:
- 🔌 Voltage fluctuations on the network.
- 🚪 Frequent opening the door.
- 🌡️ Failure of the sensors.
To accurately measure the temperature:
- Place household thermometer (preferably alcohol, as electronic may give an error) in a glass of water.
- Place the glass on the middle shelf of the refrigerator (not against the walls!) and close the door.
- Wait 8-12 hours, then check the readings.
For the freezer, the thermometer can be placed between bags of food. The optimal measurement time is at night, when the refrigerator is opened less often.
Normal fluctuations:
- In the refrigerator compartment: ±1°C from the set value.
- In the freezer compartment: ±2°C.
If there is a difference more, this is a reason to check:
- 🔧 Door seal (replacement may be required).
- 🌀 Fan operation (in models with No Frost).
- ❄️ Ice thickness on the evaporator (if exceeding 5 mm, you need defrosting).
Seasonal adjustment: winter vs summer
The temperature in the room directly affects the operation of the refrigerator. In the summer, when the air in the kitchen warms up to +25°C and above, the compressor is forced to work more intensely. In winter, especially if the refrigerator is on an unheated balcony, the opposite may occur. problem - hypothermia.
Summer settings:
- 🔥 Set the thermostat to 4–5 (for mechanics) or +3°C (for electronics).
- 🚫 Avoid placing the refrigerator next to a stove or a window that receives direct sunlight.
- 💧 Check the drainage hole - in summer it can become clogged due to high humidity.
Winter settings:
- ❄️ If the room temperature is lower +16°C, reduce the power to 2–3 (mechanics) or +5°C (electronics).
- 🔌 If there is a risk of freezing (for example, on cottage) turn off the refrigerator, drain the water and leave the door ajar.
⚠️ Attention: If the refrigerator Polair with the system No Frost is in an unheated room at a temperature below +10°C, this can lead to failure of automatic defrosting and icing of the fan. In such conditions, it is recommended to use models with manual defrosting or move the equipment to a heated area.
Typical problems and methods for eliminating them
If the refrigerator Polair does not work correctly, first check the settings. Often the problem is solved by simple adjustment:
| Problem | Possible cause | Solution |
|---|---|---|
| The refrigerator is not cools | Thermostat is set to minimum or broken | Turn the knob to 4-5, check after 6 hours. If it doesn’t help, replace the thermostat. |
| The freezer freezes food | The temperature is below −24°C or sensor is faulty | Set to −18°C, defrost the chamber. If the problem remains, diagnose the sensor. |
| The compressor runs without stopping | High room temperature or freon leak | Reduce the load (set 3–4), check the seal. If that doesn’t help, call a technician. |
| Ice forms on the back wall | The drainage hole is clogged or faulty No Frost | Clean the hole with a cotton swab, defrost the refrigerator for 12 hours. |
If problems remain after adjustment, pay attention to indirect signs of malfunctions:
- 🔊 Extraneous sounds (knocking, grinding) - the compressor or fan may break down.
- 💡 The light flashes inside the camera - lighting or board malfunction controls.
- 🌬️ Warm air from under the door - the seal or magnetic tape is damaged.
Energy saving: how to save electricity without damaging products
The refrigerator is one of the main consumers of energy in the house. (up to 30% of the total consumption). You can optimize its operation without compromising the quality of storage:
- 🔄 Vacation mode: if you are leaving for 1-2 weeks, activate this function (if available) or set it to +10°C.
- 🧊 Do not load the freezer to capacity: there should be air circulation free.
- 🔌 Move the refrigerator away from the wall 5-10 cm for better ventilation of the compressor.
- ☀️ Do not place hot dishes - this forces the compressor to work in increased mode.
For models with No Frost additional savings are achieved through:
- 🌀 Regular cleaning of the ventilation grilles (dust increases the load on the motor).
- 🔋 Using a voltage stabilizer (differences in the network increase energy consumption by 15–20%).
Comparison of energy consumption (with the same volume of 150 l):
- 🟢 Polair PCD-140 (class A+) - ~35 kWh/month.
- 🟡 Polair PCD-180I (class A++) - ~28 kWh/month.
- 🔵 Polair PCD-220NF (class A+++) - ~22 kWh/month.
FAQ: Frequently asked questions about adjusting Polair refrigerators
How to reset a Polair refrigerator to factory settings?
For mechanical models: turn the knob to 0, unplug the refrigerator for 1 minute, then turn it on and set the desired temperature.
For electronic models: press and hold the button Temp (or Set) for 5-10 seconds until the reset signal appears (display flashing or sound signal).
Why does the freezer work in the Polair refrigerator, but the refrigerator compartment does not?
This is a typical problem for models with one compressor. Possible reasons:
- Clogged capillary tube (requires cleaning by a technician).
- Malfunction switching valve between the chambers.
- Freon leak in the refrigeration circuit.
You can independently check only the tightness of the door closure and thermostat settings.
How often should you defrost a Polair refrigerator with No Frost?
The system No Frost prevents the formation of ice, but does not eliminate the need for maintenance.It is recommended:
- 🧹 Once every 6-12 months, turn off the refrigerator and wash the internal surfaces.
- 🌀 Once every 3 months, clean the ventilation grilles from dust.
- ❄️ If ice does appear (for example, due to frequent opening of the door), carry out a complete defrost on the 12–24 hours.
Is it possible to regulate the temperature in the Fresh Zone separately?
In most models Polair the fresh zone does not have a separate regulator. Its temperature depends on the general setting of the refrigerator compartment, but is usually maintained at the level 0°C ±1°C due to a separate air duct.
If you need more precise regulation, use additional thermometer and adjust the basic settings.
What to do if after adjustment the refrigerator becomes noisier?
An increase in noise level after a change in temperature is a normal phenomenon if:
- The compressor runs longer than usual (the first 1-2 hours after changing the mode).
- The mode is activated Super Freeze (fan runs at maximum speed).
If the noise does not go away after 6-12 hours, check:
- 🔧 Compressor mounting (vibrations are possible).
- 🌀 The location of the refrigerator (it should stand level, without distortions).
