Polyus refrigerator does not turn off: reasons and solutions malfunction

The refrigerator Polyus should automatically turn off every 10-20 minutes of operation to maintain the set temperature and save energy. If the unit is working without stopping, this not only increases electricity bills, but also signals serious problems. In 80% of cases, the problem is related to thermostat, freon leak or improper operation. In this article, we will analyze all the possible reasons why the refrigerator Polyus does not turn off, and we will give step-by-step recommendations for diagnosis and repair - from simple checks to complex technical manipulations.

Do not ignore the constant operation of the compressor: this can lead to overheating of the engine, failure of the start relay, or even fire due to overload of the electrical wiring. It is especially dangerous if the refrigerator is older than 10 years - in such models the parts responsible for automatic shutdown often wear out.

Before starting repairs, make sure that the problem is not temporary. For example, if you have just loaded the refrigerator with a large amount of warm food or turned on the super freezingfunction, the compressor may run longer than usual (up to 2-3 hours). But if the unit does not turn off more than 6 hours in a row this is a cause for concern.

In the article you will find:

• 🔍 Top 7 reasonswhy the refrigerator Polyus turns off (with photos and diagrams).
• 🛠️ Step-by-step instructions for diagnosing faults with your own hands.
• ⚠️ Warnings about what actions can aggravate breakdown.
• 📊 Comparative table symptoms and solutions for different models Pole.

1. Malfunction of the thermostat (thermostat)

The thermostat is the “brain” of the refrigerator, which controls the temperature and sends a signal to the compressor to turn on/off. If it breaks, the compressor will work Continuousas it does not receive a command to stop. In models Pole (for example, Pole HKF-120 or Pole KShD-240), the thermostat is usually located inside the chamber, next to the light lamp.

How to check the thermostat:

1. Disconnect the refrigerator from the mains and remove all products.
2. Remove the thermostat protective cover (usually attached to latches or screws).
3. Press the small lever button under the casing - if you hear a click, the thermostat is working. If not, the part must be replaced.

For accurate diagnostics, you can use a multimeter:

1. Turn the device into resistance testing mode (ohmmeter).
2. Attach the probes to the thermostat contacts.
3. If when rotating the temperature control knob the resistance does not change (or is equal to zero/infinity), the thermostat is faulty.

⚠️ Attention: In refrigerators Pole with electronic control (for example, Pole PKE-180) instead of a mechanical thermostat, temperature sensoris used. Checking it requires special equipment - it is better to contact the service.

2. Freon leak or clogged capillary tube

Freon is a refrigerant that circulates through the refrigerator system and removes heat. If there is leakage (for example, due to corrosion of tubes) or blockage in capillary tube, the compressor will work non-stop, trying to reach the set temperature, but to no avail. Signs of a freon leak:

• 🧊 The refrigerator freezes slightly or does not cool at all, despite constant operation.
• 🔥 The compressor gets very hot (you can check it with your hand - it should be warm, but not scalding).
• 💧 Rust or oily stains appear on the back wall of the refrigerator.

It is impossible to eliminate a freon leak on your own - it is required special equipment for soldering pipes and refilling the refrigerant. However, you can check for a blockage in the capillary tube:

1. Turn off the refrigerator and turn it with the back wall towards you.
2. Find the capillary tube (thin copper tube running from the compressor to the evaporator).
3. If the tube is covered with frost or ice, this is a sign of blockage.

⚠️ Attention: Do not try to clean the capillary tube with wire or blow it with a compressor! This may damage the system. For cleaning, a hydraulic method with nitrogen is used, which is used only in service centers.

3. Failure of the compressor or start relay

The compressor is the “heart” of the refrigerator, which pumps freon through the system. If it is worn or broken, it may run continuously but not produce the required pressure for cooling. In models Pole over 10 years old, compressors often fail due to:

• 🔋 Wear of the piston group (a characteristic sign is that the compressor hums, but does not freeze).
• 🔌 Faulty start relay (the compressor turns on and immediately turns off with a click).
• 🔥 Overheating of the windings (the compressor works, but the housing is scalding hot).

How to check compressor:

1. Turn off the refrigerator and touch the compressor housing (the black “barrel” on the back). If it is cold, the compressor does not work. If it is too hot, interturn breakdown of the windings is possible.
2. Listen to the sound: a working compressor emits a smooth hum. If you hear knocking, grinding or clicking noises, the part is faulty.

The starting relay is located next to the compressor and is responsible for starting it. If the relay is broken, the compressor may:

• Not turn on at all.
• Turn on for 1-2 seconds and turn off.
• Work continuously due to “sticking” contacts.

To check the relay:

1. Remove the relay from the compressor (disconnect the terminals and unscrew the fasteners).
2. Shake the part - if you hear knocking or rattling inside, this is a sign of a breakdown.
3. Check the resistance between the contacts with a multimeter (should be 20-40 Ohms).

What will happen if you do not repair a broken compressor?

If you ignore a compressor malfunction, this will lead to:

1) Complete failure of the engine (repair will cost 70-80% of the cost of a new refrigerator).

2) Overloading of electrical wiring and risk fire.

3) Food spoilage due to insufficient cooling.

4. Incorrect operation of the refrigerator

Sometimes the refrigerator Pole does not turn off due to trivial errors in use. Check the following points:

Temperature mode:

• 🌡️ If the temperature control is set to maximum (for example, 7 or Super Cool), the compressor will work longer than usual.
• 🥶 In hot weather (above +30°C) the refrigerator needs more time to cool.

Loading food:

• 🍗 If you put hot foods (soup, roast) in the refrigerator, it will work non-stop for 1-2 hours.
• 🧊 Overcrowded shelves impair air circulation, and the compressor is forced to work more intensely.

Ventilation:

• 🪟 The refrigerator should be at a distance 5–10 cm from the wall for normal cooling of the compressor.
• 🔥 Do not place the refrigerator next to the stove, radiator or in direct sunlight.

Door seals:

• 🚪 If the rubber band on the door is torn or dirty, warm air enters the chamber and the refrigerator runs non-stop.
• 🧼 Wipe the seal with soapy water and check the tightness: attach a sheet of paper to the closed door. If it pulls out easily, the seal needs to be replaced.

✅ Make sure the temperature regulator is not at maximum

✅ Check if the shelves are overloaded

✅ Inspect the door seals for leaks

✅ Make sure that the refrigerator is not close to the wall

✅ Disable the "Super Freeze" function (if enabled)

5. Failure of the electronic control module

In modern models Pole (for example, Pole PKT-140 or Pole PKE-200) is responsible for the operation of the compressor. electronic control unit. If it fails, the refrigerator can:

• 🔄 Work without stops.
• 🔥 Turn on and turn off immediately.
• 📛 Show errors on the display (for example, E1, E2).

Causes of module failure:

• ⚡ Voltage surges in the network (especially relevant for dachas and private houses).
• 💧 Moisture getting on the board (for example, during defrosting).
• 🔌 Short circuit due to wear of the wiring.

It is almost impossible to repair the electronic module yourself - you need soldering equipment and a board diagram. However, you can:

1. Turn off the refrigerator for 10-15 minutes and then turn it on again (sometimes resetting the settings helps).
2. Check the fuse on the board (if it is blown, you can replace it yourself).

⚠️ Attention: If the refrigerator is under warranty, do not open the electronic module yourself. This will lead to loss of warranty service. Contact an authorized service center. center Pole.

6. Clogged drainage system or fan

In refrigerators Polyus with system No Frost (for example, Polyus PKN-160) the fan is responsible for air circulation. If it becomes clogged with ice or dust, the compressor starts working harder, trying to compensate for the lack of cooling. Signs of blockage:

• 🌬️ Weak or warm air is blowing in the refrigerator compartment.
• ❄️ A thick layer of ice forms on the back wall.
• 🔊 The fan is noisy or does not rotate.

How to clean fan:

1. Unplug the refrigerator and defrost it (at least 12 hours).
2. Remove the back panel in the freezer (usually secured with screws).
3. Remove ice and dirt from the fan blades with a cotton swab or soft brush.
4. Check the drainage hole (at the bottom of the refrigerator) - if it is clogged, water will accumulate and freeze.

If the fan does not work after cleaning, its motor may be broken. In this case, the part must be replaced.

7. Temperature sensor malfunction (in models with an electronic one). control)

In refrigerators Pole with a display (for example, Pole PKE-180) instead of a mechanical thermostat, temperature sensoris used. If it fails, the control unit receives incorrect data and forces the compressor to work without stopping.

Signs of sensor malfunction:

• 📉 The temperature in the chamber does not correspond to the set one (for example, on display +5°C, and inside +10°C).
• 🔄 The refrigerator either freezes too much or barely cools.
• 🚨 An error appears on the display (for example, E3 or SENSOR ERROR).

How to check sensor:

1. Find the sensor (usually it is located on the back wall of the refrigerator compartment, inside the plastic box).
2. Disconnect the connector and check the resistance with a multimeter. At room temperature it should be about 5–7 kOhm.
3. If the resistance equals 0 (short circuit) or ∞ (break), the sensor is faulty.

Replacing the temperature sensor will cost 1,500–3,000 rubles (depending on the refrigerator model. You can replace it yourself if you are confident in your soldering and work skills). with electronics.

Frequently asked questions

Is it possible to fill the refrigerator with freon yourself Polyus?

No. Refilling freon requires special equipment (vacuum pump, pressure gauges, etc.) refrigerant cylinder) and a certificate for working with freon. Incorrect filling can lead to explosion or poisoning (freon is toxic). Contact the service.

How long should the refrigerator operate before automatic operation? shutdown? Pole before automatic shutdown?

In normal mode, the compressor operates 10–20 minutes., then turns off for 20–30 minutesThe ratio of work and rest depends on:

• Room temperature (the hotter, the longer it works).
• Refrigerator load.
• Set cooling mode.

If the compressor is running more than 1 hour without stopping is a sign of a malfunction.

What to do if the refrigerator Pole does not turn off, but freezes normally?

Rather In general, the problem is thermostat or temperature sensor. The compressor runs continuously because it does not receive a signal that the desired temperature has been reached. Try:

1. Adjust the temperature to a higher value. (for example, from 5 to 3).
2. Check the thermostat with a multimeter (instructions above).
3. If that doesn’t help, replace the thermostat or sensor.

Why a new refrigerator Polyus works without stopping first day?

This is normal! When you turn it on for the first time, the refrigerator reaches the desired temperature in the chambers, so the compressor can work. up to 8–10 hours. in a rowIf after a day the mode has not returned to normal, check the settings and seals.

Can a power surge cause continuous operation of the refrigerator?

Yes. Voltage surges often damage:

• Electronic control module (the refrigerator does not respond to settings).
• Start relay (the compressor turns on and immediately turns off).
• Temperature sensors (show incorrect values).

To protect the refrigerator, use voltage stabilizer or surge protector.
