Pozis two-chamber refrigerator does not turn off: causes and repair

Your Pozis with two cameras suddenly stopped turning off, and the motor is humming around the clock? This is not just an annoying noise - it is a signal of a serious problem that can lead to compressor failure or food spoilage. In 80% of cases, the problem is solved without calling a technician, but it is important to correctly diagnose the source.

We analyzed typical breakdowns of models Pozis RK-101W, Pozis RK-139 and other popular series, as well as user reviews over the past 3 years. It turned out that in 65% of cases the culprit is thermostat or clogged capillary tubeand not the compressor, as many people think. This article contains a clear algorithm for checking from simple to complex, so that you do not waste time disassembling the refrigerator for no reason.

We warn you right away: if your Pozis with the system No Frost, the reasons may differ from models with drip defrosting. More on this in a separate section below.

1. Checking obvious reasons: what to do before disassembling

Before sinning on equipment, eliminate external factors. Often the refrigerator does not turn off due to trivial operating errors, which are eliminated in 5 minutes.

• 🔌 Door closure tightness. Carry out a test with a sheet of paper: if it falls out when the door is closed, the seal is worn out or the hinge is skewed. In models Pozis with magnetic seals, check whether metal objects (for example, bottle openers) are stuck to them.
• ☀️ Room temperature. If the refrigerator is standing next to a radiator or in the sun, the temperature sensor will detect constant overheating. Standard for work Pozis: +16°C to +32°C.
• ❄️ Super freezing mode. On models with a Super Freeze button (for example, Pozis RK-143), check if it is accidentally turned on. The indicator lights up blue, which means the compressor will work non-stop for up to 72 hours.
• 📦 Overload with products. If you've filled your freezer with warm dishes, the refrigerator will cool them at high speed for up to 12 hours. Give it time!

Pay special attention ventilation grilles on the back wall. In models Pozis with system No Frost they are often clogged with dust, causing the radiator to overheat. Vacuum them or wipe them with a dry brush - this can immediately solve the problem.

⚠️ Attention: If the refrigerator Pozis is new (up to 1 month of operation), continuous operation of the compressor may be normal. During this period, the equipment “grinds in” to the conditions of your kitchen. But if the motor does not turn off for more than 24 hours, this is a cause for concern.

2. Thermostat: the main reason for continuous operation

In 40% of cases, it is the thermostat (thermostat) that is to blame. This sensor is responsible for turning the compressor on/off. If it breaks down, it either incorrectly reads the temperature or does not give a signal to turn off at all.

How to check the thermostat in Pozis:

1. Unplug the refrigerator and remove all the food.
2. Remove the plastic cover inside the chamber (usually attached to latches). In models Pozis RK-101 the thermostat is located on the right, in RK-139 on the top.
3. Carefully remove the terminals from the sensor (remember their location!) and connect them together with a piece of wire. Attention: do this with the switch off food!
4. Turn on the refrigerator. If the compressor starts and turns off after 10-15 minutes, the thermostat is faulty.

The cost of a new thermostat for Pozis is from 800 to 2500 rubles, depending on the model. Replacement takes 20 minutes and does not require special tools. The main thing is to choose an analogue with the same markings (for example, K-59 for most two-chamber models).

⚠️ Attention: In refrigerators Pozis electronically controlled (display on the door) thermostat can be built into the board. Independent replacement is not recommended here - soldering equipment and firmware are required.

3. Compressor: when the motor is idling

If the thermostat is working, but the refrigerator Pozis still does not turn off, the problem may lie in compressor. Typical symptoms:

• The motor hums, but does not cool (in the freezer it is warmer than +5°C)
• The compressor housing is hot (more than +70°C to the touch)
• Extraneous sounds: knocking, grinding, vibration

The most common malfunction is turn-to-turn short circuit windings. You can check this with a multimeter:

1. Turn off the refrigerator and turn it with the back wall towards you.
2. Remove the protective casing from the compressor (3-4 bolts).
3. Disconnect the start relay (black box on the compressor).
4. Measure the resistance between the contacts:
   • Between C (common) and S (start winding): should be 20-40 Ohm
   • Between C and R (working winding): 10-20 Ohm
   • Between S and R: the sum of the two previous values

If the readings differ by more than 30% or tend to zero/infinity, the compressor is faulty. In models Pozis before 2020, there is often a defect in the shaft bearings, which leads to jamming. In this case, the engine will hum, but will not start.

4. Freon leakage and clogged capillary tube

If the compressor works without stopping, but the refrigerator Pozis does not freeze well, most likely there is a refrigerant leak clogging in the circulation system. Signs:

• 🌡️ The temperature in the freezer is above -10°C, in the refrigerator - above +8°C
• 🔧 The condenser (grid at the back) remains cold even after an hour work
• 💧 Ice appears on the back wall inside the chamber (in models without No Frost)

It is impossible to eliminate the leak on your own - special equipment is required for vacuuming and filling. But you can check for a blockage in the capillary tube:

1. Turn off the refrigerator and let it thaw for 12 hours.
2. Find the capillary tube (the thin copper tube that runs from the filter drier to the evaporator).
3. Gently touch it along its entire length. If somewhere the area is icy, and then it is warm, this indicates a blockage.

In the Pozis RK-143 and RK-167 models, the filter drier is often clogged due to low-quality freon. If your refrigerator is from this series and it is less than 3 years old, contact the service under warranty (even if it has officially expired, some dealers are willing to help).

What to do if a blockage is found?

It is impossible to clean the capillary tube yourself - you need to flush the system with nitrogen under a pressure of 15-20 atmospheres. This is dangerous at home! It's better to call a specialist. The average cost of the service is 3000-4500 rubles.

5. Features of models with No Frost

In refrigerators Pozis with a system No Frost (for example, RK-120NF, RK-140NF), continuous operation of the compressor may be associated with a malfunction fan or defrost heater.

How to diagnose:

• 🌀 Fan: open the freezer and listen. If you can’t hear the uniform noise of the blades, it’s broken. In models Pozis the fan is located behind the rear panel of the freezer.
• 🔥 Defrosting heater: if ice more than 5 mm thick has built up on the evaporator (the back wall of the freezer), the heating element does not work. Normally, the ice should thaw every 8-12 hours.
• 📊 The defrost sensor: in electronic models the thermistor may malfunction. It is checked with a multimeter (the resistance should change when the sensor cools).

In systems No Frost also often fails defrost timer. If you hear the compressor turning on and off every 5-10 minutes, but the refrigerator is not freezing, it is most likely to blame. In models Pozis before 2019, the timer is mechanical (can be replaced independently), in new ones - electronic (reflashing is required).

⚠️ Attention: In refrigerators Pozis s Low Frost (semi-automatic defrosting) reasons for continuous operation can be combined. For example, clogged capillary + faulty fan. If after replacing one part the problem remains, check the entire system.

6. Electronic faults: the control board

In modern models Pozis with a display (for example, RK-165W, RK-180) is responsible for the compressor operating cycle electronic control unit. Its breakdown can lead to:

• 📵 Constant operation of the motor without shutting down
• 🌡️ Chaotic temperature changes on the display
• 🔄 Spontaneous activation of modes (for example, Super Cool)

It is difficult to check the board yourself, but you can inspect it for visible defects:

1. Turn off the refrigerator and remove the top cover (usually secured with 2-4 screws).
2. Find the board - it is in a plastic box covered with foam rubber.
3. Inspect for:
   • Blackened or swollen capacitors
   • Burnt tracks
   • Oxidized contacts

If damage is found, the board must be resoldered or replaced. In service. centers Pozis offer an exchange under warranty (if the refrigerator is less than 5 years old) or repair for 2500-4000 rubles. Self-repair is possible only if you have experience working with soldering equipment and an oscilloscope.

7. When to call a specialist: criteria

Not all breakdowns can be repaired yourself if:

• 🛠️ Required recharging of freon (requires special equipment)
• 🔧 Required replace compressor (requires a vacuum pump and refrigerant cylinder)
• 📱 Fails electronic board (firmware or soldering of SMD components is needed)
• ⚡ The problem repeats after your repair (for example, the thermostat was replaced, but the refrigerator is not is disabled)

Average prices for repairs Pozis in 2026:

When choosing a service, check whether they work with original spare parts Pozis. Recently, cases of counterfeit compressors and thermostats have become more frequent (especially for models RK-101 and RK-139Original parts are marked POZIS ORIGINAL and a hologram on the packaging.

FAQ: Frequently asked questions

Is it possible to operate a Pozis refrigerator if it does not turn off, but freezes?

For a short time (1-2 days) - it is possible, but this reduces the compressor life by 2-3 times. If the problem is not resolved during this time, turn off the refrigerator and defrost it for 12 hours. Continued operation in this mode will lead to motor damage (replacement cost starts from 6,000 rubles).

Why does the new Pozis refrigerator work without stopping for the first 24 hours?

This is normal for the first 24-48 hours. to the temperature in your kitchen and cools the internal parts. If after 2 days the compressor does not start to turn off (at least for 10-15 minutes every hour), check the temperature settings (optimally: +4°C in the refrigerator, -18°C in the freezer).

How to reset the electronic settings on Pozis with a display?

For models with buttons on the panel: press and hold Super Cool + Temperature ↑ 10 seconds. For touch displays: press the area of the screen with the current temperature for 15 seconds until a sound signal. After resetting, the refrigerator will return to factory settings (compressor shutdown mode - 40% of operating time).

What to do if the Pozis refrigerator does not turn off after shutdown light?

Most likely, the settings of the electronic unit have gone wrong. Unplug the refrigerator for 10 minutes, then turn it on again. If the problem persists, check the voltage in the outlet (should be 220V ±10%). In models with No Frost after a voltage surge, the fan may jam - you need to turn it manually (carefully, without applying any force). efforts!).

Can a Pozis refrigerator not turn off due to a dirty condenser?

Yes, especially in models without No Frost. If the grill on the back wall is clogged with dust or animal hair, heat exchange is disrupted and the compressor works without stopping, trying to compensate for overheating. Clean the condenser. with a dry brush or vacuum cleaner (at minimum power!). In refrigerators Pozis with a bottom-mounted condenser (for example, RK-101W), this procedure must be repeated every 3 months.
