The main chamber of the refrigerator does not freeze - what to do? Causes and solutions

Have you opened the refrigerator, and the food in the main chamber is warm, although the freezer compartment is working as usual? This is one of the most common malfunctions that owners of refrigerators Atlant, Indesit, Samsung and other brands encounter. In 70% of cases, the problem is solved without calling a technician, but to do this, you need to correctly diagnose the cause.

In this article we will analyze 10 main reasonswhy the main chamber stopped freezing, but the freezer is functioning normally. You will learn how to test the thermostat, sensors, compressor and refrigerant circulation system yourself. We will also give step-by-step instructions to troubleshoot problems and tell you in which cases professional repairs are indispensable.

Important: if the refrigerator does not turn on at all or makes uncharacteristic sounds (knocking, grinding, humming), this may indicate critical breakdowns - immediately disconnect it from the network and do not try to defrost it forcibly.

1. Incorrect temperature settings

The first thing to check is refrigerator operating mode. Often, users accidentally change the settings, turn on the "Vacation" mode, or set the temperature in the main chamber too high. Modern models (for example LG DoorCooling+ or Samsung Twin Cooling Plus) have separate controls for the refrigerator and freezer compartments.

How to check:

• 🔍 Look at the control panel to see if the indicator is on "Super Cool" or "Holiday"? These modes turn off the cooling of the main chamber.
• 📉 Make sure that the temperature is set in the range +2°C...+5°C. In some models (Bosch KIN86AF30, Liebert HRS), the factory settings are lost after a power surge.
• 🔄 If an error flashes on the display (for example, E1, H1), this may mean a program failure - try restarting the refrigerator (pull out the plug on 10 minutes).

In refrigerators with mechanical controls (for example, Biryusa 145 or Nord 243), the temperature control may be accidentally turned to the "OFF" or "MIN" position. Check if something inside the chamber is blocking it (for example, food packaging).

2. Clogging of the No Frost or drip defrosting system

If your refrigerator is equipped with a No Frost (Samsung RB37J5230, Indesit DF 5200or drip defrosting (Atlant MHM 1705, Stinol 102system), the reason for the lack of cold may be clogged drain hole or evaporator. Over time, ice, dust and mold accumulate there, which blocks air circulation.

Signs blockage:

• ❄️ A thick layer of ice forms on the back wall of the refrigerator compartment.
• 💨 The fan is louder than usual, but no cold is coming in.
• 🌡️ The temperature in the freezer is normal, but in the main chamber it is - above +10°C.

How to clean the system:

1. Unplug the refrigerator and defrost it at least 12 hours (in models with No Frost you cannot use a hairdryer or hot water!).
2. Clean the drainage hole (usually located at the bottom of the back wall) using a cotton swab or a special brush.
3. Rinse the internal surfaces with a soda solution (1 tablespoon per 1 liter of water) to remove mold.

In refrigerators with a system Full No Frost (for example, Electrolux ENN 2853), the blockage may be in the air duct between the freezer and the main chamber. If the problem remains after defrosting, professional cleaning will be required by disassembling the rear panel.

3. Malfunction of the thermostat or temperature sensor

The thermostat (or thermostat) is the “brain” of the refrigerator, which controls the on/off of the compressor. If it fails, the compressor either does not turn on at all, or works without stopping, but the cold does not enter the main chamber. In modern models (Samsung RL38, LG GA-B489), instead of a mechanical thermostat, electronic sensors are used, which can also break.

How to check the thermostat:

• 🔧 In mechanical refrigerators (Biryusa 6M, Nord 210) turn the thermostat knob to maximum. If the compressor does not start, the thermostat is faulty.
• 📊 In electronic models (Bosch KGE39XW20, Liebherr CP 3313) the sensor error is usually displayed on the display (codes F2, Er DS).
• 🔌 Call the thermostat with a multimeter: at room temperature the contacts should be closed (resistance ~0 Ohm).

Replacing the thermostat in mechanical models is cheaper than repairing electronic sensors. If you are not confident in your skills, it is better to call a technician, since incorrect installation can lead to overheating. compressor.

4. Freon leak or blockage of the capillary tube

Freon is a refrigerant that circulates through the refrigerator system and provides cooling. If freon leakage or a blockage occurs capillary tube, the compressor is working. idle, and the cold does not enter the main chamber. In this case, the freezer can continue to freeze, since it is connected to a separate circuit (in models with two compressors) or receives residual cold.

Signs of a leak freon:

• ⚙️ The compressor works without stopping, but does not cool.
• 🔥 The refrigerator body heats up more than usual.
• 🛠️ Oil stains are visible on the back wall (a sign of damage to the tube).

What do:

• 🚫 Do not try to fill freon yourself! This is dangerous and requires special equipment.
• 🔍 Inspect the back wall of the refrigerator for corrosion or mechanical damage to the tubes.
• 📞 Call a technician for diagnostics. Average cost. refilling freon - 3,500–6,000 rubles., depending on the model.

How to check for freon leaks without a technician?

If you have a leak detector (a device for detecting freon), run it along circuit tubes. If there is a leak, the device will make a sound. At home, you can use a soap solution: apply it to suspicious areas - if there is a leak, bubbles will appear.

In refrigerators with one compressor (Atlant MHM 1703, Stinol 101) a freon leak usually leads to a complete lack of cold in both chambers. If the freezer works, but the main chamber does not, most likely the problem is in clogging of the capillary tube or malfunction of the switching valve (in models with a system Twin Cooling).

5. Breakdown compressor or start relay

The compressor is the “heart” of the refrigerator, which pumps freon through the system. If it fails, the refrigerator stops freezing. In models with one compressor (Biryusa 220, Nord 254), a breakdown leads to the shutdown of both chambers, but in refrigerators with two compressors (Samsung RL-44, LG GR-B207) only one can fail. circuit.

Signs of a compressor malfunction:

• 🔇 The compressor does not turn on at all (no characteristic hum).
• 🔥 The compressor housing gets very hot (more than 90°C).
• ⚡ Protection is triggered (knocks out plugs or RCD when turned on).

How to diagnose:

1. Check that is power supplied to the compressor (use a multimeter in continuity mode).
2. Listen to see if the compressor turns on: if it hums, but does not start, the problem is in start relay.
3. If the compressor does not respond at all, the winding may have burned out.

The cost of replacing a compressor is from 8,000 rubles. (including work and refilling freon In older models). (ZIL-63, Minsk-15M) sometimes it is cheaper to buy a new refrigerator than to repair an old one.

6. Problems with the fan or. damper

In refrigerators with a system No Frost cold air from the freezer enters the main chamber through fan and damper. If the fan breaks or the damper freezes in the closed position, the main chamber stops cooling, and the freezer continues to operate.

How to check:

• 🌀 When the freezer door is open, you should hear the fan operating. If you can’t hear it, it’s broken.
• 🔍 Shine a flashlight into the air duct (usually located in the upper part of the back). walls). If there is ice there, the damper is frozen.
• 🌡️ In some models (Electrolux ERN 1400), when the fan breaks down, an error appears on the display F4 or Er CF.

What to do:

• 🔧 If the fan does not spin, check whether it is blocked by ice or foreign objects.
• 🔥 Defrost the refrigerator for 24 hours so that the ice on the damper melts.
• 🛠️ If the fan is burned out, a replacement will be required (the cost of the part is from 1,500 rub.).

In models with electronic damper (Bosch KAN90VI20, Siemens KG39NXB35), the problem may be a malfunction of the damper motor. In this case, the display usually displays an error E22 or Er DH.

7. Malfunction of the control board

In modern electronically controlled refrigerators (Samsung RL-60, LG GR-N309, Indesit BIAA 13) the cold distribution is responsible the board. control. If it fails, the refrigerator can behave unpredictably: for example, the freezer works, but the main chamber does not, or vice versa.

Signs of board failure:

• 📛 Random characters or errors are displayed on the display (E1, Er IF, H1).
• 🔄 The refrigerator spontaneously turns on/off modes.
• 🔌 After a power surge, the refrigerator stopped responding to buttons.

What to do:

• 🔌 Try resetting the settings by unplugging the refrigerator for 15 minutes.
• 🔧 Inspect the board for swollen capacitors or burnt tracks.
• 📞 If the board is burned out - it can be repaired (soldering elements) or replaced (the cost of a new board is from 5,000 rubles.).

How to protect the board from power surges?

Install a voltage stabilizer or phase control relay (for example, Zubr R116y). This will prevent output boards fail due to changes in the network.

In refrigerators Atlant i Biryusa control boards often fail due to moisture (for example, during defrosting) If you notice corrosion on the board, it is better to replace it, since repairs may not give a long-term result.

8. Loss of door seal

If the sealing rubber on the refrigerator door is worn out or deformed, warm air enters the chamber and the compressor cannot cope with the load. As a result, the main chamber stops freezing, but the freezer continues to work (since its door is sealed). data-i="224">How to check the tightness:

How to check for leaks:

• 📄 Take a sheet of paper and squeeze it between the door and the body. If the sheet is easily pulled out, the seal is faulty.
• 🔍 Inspect the rubber for cracks, tears or deformation.
• 🧊 If condensation constantly forms on the door, this is a sign of a leak.

What to do:

• 🧼 Wash the seal with warm water and soap - sometimes it sticks due to grease or dirt.
• 🔥 Warm up the deformed areas with a hairdryer (temperature 50–60°C) so that the rubber takes its original shape.
• 🛠️ If the seal is torn, replace it (the cost of a new one is from 800 rub.).

In models with double door (Samsung Family Hub), the problem may be a malfunction. closing mechanism. If the door does not close tightly, the refrigerator will constantly hum, trying to compensate for the loss of cold.

FAQ: Frequently asked questions about the main chamber not working

❓ The refrigerator does not freeze, but the light inside is on. problem?

If the light turns on, but the compressor does not work, the problem may be thermostat, start relay or control boardCheck whether power is supplied to the compressor (touch it - if it is cold, then it does not turn on.

❓ The freezer works, but the refrigerator does not. What is broken?

Probable reasons:

1. Clogged system No Frost or drip defrost.
2. Fault fan or damper (in models with one compressor).
3. Freon leak in refrigerator circuit.
4. Failure temperature sensor main camera.

Start by defrosting the refrigerator for 12-24 hours. If the problem persists, call a technician for diagnostics.

❓ Is it possible to refill freon yourself?

⚠️ No! Refilling freon requires special equipment (vacuum pump, pressure manifold) and skills. Incorrect filling can lead to:

• Damage to the compressor.
• Moisture entering the system (which will damage the capillary tube).
• Freon leakage and environmental pollution.

The average cost of refilling at a service center is 3,500–6,000 rubles..

❓ How much does it cost to repair if the main chamber does not freeze?

The cost depends on the cause of the breakdown:

Malfunction	Repair cost (rub.)
Replacing the thermostat	1 200–2 500
Cleaning the No Frost system	2 000–3 500
Replacing the fan	1 500–2 800
Refilling freon	3 500–6 000
Repairing the control board	4 000–7 000

In old refrigerators (over 10 years old), repairs may be unprofitable - sometimes it is cheaper to buy new equipment.

❓ How to prevent breakdown of the main one cameras?

Preventive measures:

• 🧊 Defrost the refrigerator at least once every 6 months (even if it has No Frost).
• 🔌 Use voltage stabilizer to protect against surges in the network.
• 🧽 Wash the rubber seal regularly and check its tightness.
• 🚫 Do not place the refrigerator near heat sources (battery, stove, window on the sunny side).
