The Pozis refrigerator is very cold: reasons and what to do

If your refrigerator Pozis started working in “eternal winter” mode - it freezes food in the main chamber, covers the back wall with a thick layer of ice, or does not turn off at all, the problem requires an urgent solution. Such a malfunction not only spoils the food, but also leads to increased energy consumption, overload of the compressor and the risk of serious breakdown. In most cases, excessive cooling is associated with control system failures or mechanical failures. However, refrigerators

In most cases, excessive cooling is due to incorrect settings, control system failures or mechanical failures. However, refrigerators Pozis (especially models Pozis RK-101W, Pozis RK-149 and series FK) have their own “weak points” that are worth knowing about. Next, we will analyze all the possible reasons - from trivial to hidden - and give clear instructions on how to return the equipment to normal operation.

⚠️ Important: If the refrigerator Pozis not only gets very cold, but also makes uncharacteristic sounds (knocking, humming, clicking), go straight to the section about compressor malfunctions —this can be critical.

1. The thermostat or thermostat is faulty

The thermostat (or thermostat) is the “brain” of the refrigerator, which controls the temperature and sends signals to the compressor to turn on/off. If it is broken or does not work correctly, the compressor can continuously drive cold, thinking that the temperature in the chamber is not yet low enough.

Signs of a malfunctioning thermostat Pozis:

• 🔹 The refrigerator does not turn off at all (the compressor works 24/7).
• 🔹 Temperature in the main chamber it drops lower +2°C, the products freeze slightly.
• 🔹 Manually changing the mode (for example, from Normal to Eco) has no effect.
• 🔹 The display (if any) shows error E1, E2 or the temperature indicator is flashing.

How to check the thermostat yourself:

1. Unplug the refrigerator.
2. Remove the protective cover from the thermostat (usually located next to the light bulb or on the back wall).
3. Carefully remove the thermostat and check it with a multimeter in dial mode. At room temperature, the contacts should be closed.
4. Immerse the thermostat sensor in ice for 10-15 minutes - the contacts should open.

If the thermostat does not respond to temperature changes, it needs to be replaced. For models Pozis thermostats are suitable K59-L1938 (for single-chamber) or WDF19 (for double-chamber). The cost of the part is from 800 to 1500 rubles.

2. The temperature or operating mode settings are lost

Often the problem lies not in a breakdown, but in accidentally changed settings. Refrigerators Pozis have several "traps":

• 🔸 "Super Freeze" mode (Super Freeze or Fast Cool) - if you do not turn it off, the refrigerator will freeze at maximum for up to 72 hours.
• 🔸 Incorrect temperature range. Optimal values for Pozis:
  • 🍎 Main chamber: +3…+5°C
  • ❄️ Freezer compartment: -18…-20°C
• 🔸 Failure after power outage — some models reset the settings to factory settings (+2°C in the refrigerator camera).

How to reset settings on Pozis:

1. On models with mechanical controls (Pozis RK-101W, FK-120), turn the temperature control to 0, then set to 2–3 (middle position).
2. On electronic panels (Pozis RK-149, RK-167), press the button Set (or Mode) for 5-10 seconds to reset.
3. Check whether the mode is disabled Super Freeze —its indicator should not be lit.

Make sure that the "Super Freeze" mode is turned off|

Check the current temperature on the display (should be +3...+5°C)|

If after resetting the problem remains, proceed to the next sections - it's not the settings.

3. Wear or damage to the sealing rubber

The sealing rubber on the refrigerator door Pozis over time loses elasticity, cracks or deforms. Because of this, warm air constantly penetrates into the chamber, and the compressor is forced to work without stopping, trying to compensate for the loss of cold.

Signs of problems with the seal:

• 🔺 Ice or frost forms on the back wall of the refrigerator compartment.
• 🔺 The door closes not tight (there are gaps).
• 🔺 Dirt, mold or cracks are visible around the rubber band.
• 🔺 When the door is closed, the light inside is on (on models with a closure sensor).

How to check the tightness:

1. Take a sheet of A4 paper.
2. Place it between the seal and the refrigerator body.
3. Close the door and try to pull out the sheet. If it slipped out easily the seal is faulty.

Solutions:

• 🛠️ Cleaning and restoration: Wash the rubber band with warm water and soap, lubricate it with silicone grease (for example, WD-40 Specialist).
• 🔧 Heating and leveling: Heat the seal with a hairdryer (temperature 50–60°C) and shape it by pressing the door.
• 🛒 Replacement: For Pozis suitable elastic bands 580x520 mm (for single-chamber) or 1160x520 mm (for double-chamber). Average price - 1200–2500 rubles.

4. Failure of the temperature sensor

In modern models Pozis (for example, RK-149, RK-167), instead of a mechanical thermostat, an electronic temperature sensor is used. If it breaks, the control unit receives incorrect data and causes the compressor to freeze without stopping.

Symptoms of a faulty sensor:

• 📉 The temperature on the display flashes or shows inadequate values (for example, -30°C in the refrigerator compartment).
• 🔄 The refrigerator spontaneously switches between modes.
• 🚨 An error appears on the display E3, E4 or SENSOR ERROR.

How to diagnose the sensor:

1. Disconnect the refrigerator from the network.
2. Remove the back panel in the refrigerator compartment (usually the sensor is located next to evaporator).
3. Test the sensor with a multimeter. The resistance at +20°C should be within 5–7 kOhm.
4. Immerse the sensor in cold water - the resistance should be increase.

If the sensor does not respond, it needs to be replaced. For Pozis sensors are suitable NTC 10kOhm or B57560G104F (analogue from EPCOS). 800 rubles.

Where to buy a sensor for Pozis?

Original sensors can be ordered from official Pozis dealers or service centers. Analogs (for example, from EPCOS or Thermik) are sold in radio parts stores (ChipDip, MasterKit) or on AliExpress. When purchasing, check compatibility with your model - some sensors require soldering or adapting connectors.

5. Problems with the compressor or refrigerant

If the refrigerator Pozis not only gets very cold, but also makes uncharacteristic sounds (humming, knocking, vibration), the problem may lie in the compressor or refrigerant circulation system. Here are the most common malfunctions:

⚠️ Attention: If the problem is related to the refrigerant or compressor, do not try to repair it yourself. Freon is toxic, and improper refilling can lead to an explosion. Contact a service center Pozis or a technician with a license to work with refrigerants.

Repair cost:

• 💰 Compressor replacement: 5000–12000 rubles (including work).
• 💰 Refilling freon: 2500–4000 rubles.
• 💰 Replacing the expansion valve: 3000–6000 rubles.

6. Malfunction of the fan or No Frost system

Refrigerators Pozis with the system No Frost (models RK-149NF, RK-167NF) are equipped with a fan that distributes cold air among the chambers. If it breaks or freezes, the cold stops circulating evenly, and part of the chamber begins to freeze, and the other, on the contrary, does not cool well.

Signs of problems with the fan:

• 🌀 The refrigerator compartment is too cold, and the freezer compartment is warmer than usual (or vice versa).
• 🌀 Noise, grinding or crackling is heard during operation.
• 🌀 Ice (“fur coat”) is growing on the back wall of the freezer.

How to troubleshoot:

1. Turn off the refrigerator and defrost it on 12–24 hours.
2. After defrosting, check whether the fan rotates. If not, it may have iced up or the motor has burned out.
3. Test the fan winding with a multimeter. The resistance should be within 200–500 Ohm.
4. If the fan does not work, replace it. For Pozis models are suitable YDK120-12 or MZD120.

⚠️ Attention: If after defrosting the ice builds up again within 1–2 weeksthe problem may be in defrost heater or the timer No Frost. In this case, diagnostics at the service is required.

7. Incorrect installation or external factors

Sometimes the refrigerator Pozis freezes too much not because of a breakdown, but because of improper operation. Check the following points:

• 📍 Distance to the wall: If the refrigerator is standing close to each other, air circulation is disrupted and the compressor overheats, causing wear and tear. The optimal gap is 5–10 cm.
• ☀️ Direct sunlight or heating: If the refrigerator is located next to a stove, radiator or window, it will try to compensate for external heat.
• 🔌 Unstable voltage: Voltage surges can knock down the electronic control unit. Use a stabilizer (for example, Resanta ASN-1000).
• 🧊 Overload products: If the refrigerator is packed to capacity, the air does not circulate and the temperature is distributed unevenly.

How to fix:

• 🔧 Move the refrigerator away from heat sources.
• 🔧 Install a voltage stabilizer (especially important for rural areas).
• 🔧 Do not load the refrigerator more than 70% from the volume.
• 🔧 Check whether the drainage system hose is pinched (if there is condensation on the floor).

FAQ: Frequently asked questions about Pozis refrigerators

My Pozis RK-101W refrigerator freezes so much that the food is covered with ice. What should I do?

First check the settings: set the temperature control to position 2–3 (medium). defrost the refrigerator for 12 hours and check the sealing rubber. If the problem remains, the thermostat is most likely faulty (K59-L1938).

The Pozis RK-149 display shows error E2. What does this mean?

Error E2 indicates a problem with the refrigerator temperature sensor. Try turning off the refrigerator at 10 minutes, then turning it on again. If the error remains, the sensor needs to be replaced (cost - about 500 rubles).

The compressor works without stopping, but the refrigerator does not turn off. What's the matter?

Probable reasons:

1. The thermostat or temperature sensor is faulty.
2. Refrigerant leakage (freon).
3. The thermostatic valve (TEV) is jammed.

You can check only the thermostat yourself (see section 1). For the rest, you need a specialist.

After defrosting, the Pozis refrigerator began to freeze even more. stronger. Why?

Perhaps the temperature sensor or seal was damaged during defrosting. Also check if moisture got into the electronic control unit. If the refrigerator is with No Frost, the defrost heater could burn out - in this case, ice will build up again after 1–2 weeks.

Is it worth repairing an old Pozis refrigerator or is it better to buy a new one?

Focus on the cost of repairs:

• If repairs cost $ 30–50% of the price of a new refrigerator -it makes sense to repair.
• If the breakdown is serious (compressor, freon leak) and the refrigerator is larger 10 years it is cheaper to buy a new one.

For Pozis critical threshold - 7–8 years. After this period, electronic components begin to fail en masse.
