The refrigerator has stopped cooling and freezing: 10 reasons and what to do right now

Has the refrigerator stopped freezing, and instead of being cool, the main chamber is at room temperature? Don't rush to call a specialist. In 60% of cases the problem is solved without disassembling the equipment: it is enough to remove the blockage, restart the system or adjust the settings. But if you ignore the first signs, the breakdown will worsen, and repairs will cost 2-3 times more expensive.

In this article we will look all possible reasonswhy the refrigerator does not cool or freeze - from a banal power outage to failure compressor. You will learn how diagnose the malfunction by the sounds and behavior of the equipment, what manipulations you can do yourself, and when immediately disconnect the refrigerator from the network. We also present step by step instructions for NoFrost systems and drip models —they differ in operating principles and “symptoms” of breakdowns.

⚠️ Warning: If the refrigerator turns on, but does not freeze and at the same time emits loud humming or relay clicks it is a sign of compressor overheating. Immediately disconnect the equipment from the network and do not turn it on until the cause is eliminated!

1. First steps: what to check before diagnostics

Before disassembling the refrigerator or looking for a technician, eliminate external factors that could trigger the failure. Start with the most obvious:

• 🔌 Power: Make sure that the plug is firmly inserted into the outlet and that the outlet itself works (connect another device, for example, a phone charger). If the refrigerator is connected through an extension cord, check it for melting or overheating.
• ⚡ Network voltage: During voltage surges (lower 180 V or higher 240 V), the compressor may not start. Use a voltage stabilizer or relay if there are frequent fluctuations in your area.
• 📛 Door: Check whether the refrigerator door is tightly closed. Even a small gap in 2–3 mm will lead to the entry of warm air and malfunction. Inspect the seal for cracks or deformations.
• ❄️ Operating mode: The mode Vacation or Ecomay be activated, in which the freezer compartment is running and the main compartment is turned off. Look at the instructions for the model - the combinations of buttons for resetting the mode Samsung, LG and Indesit are different.

If everything is in order, but the refrigerator still does not freeze, proceed to diagnosing the internal systems. Pay attention to the sounds: the compressor may hum, click, or show no signs of life at all. This is the key to determining the cause.

2. The compressor works, but does not freeze: 4 reasons

If the compressor buzzes or vibrates slightly, but the refrigerator does not cool, the problem lies in one of the four systems. Let's consider them in descending order of probability.

2.1. Freon (refrigerant) leak

Freon is a gas that circulates through the refrigerator tubes and removes heat. If there is a leak (for example, due to corrosion of tubes or mechanical damage), the compressor runs idle: it drives air instead of refrigerant. Symptoms:

• The compressor works without stopping or with minimal pauses.
• Condenser (grid on the rear wall) remains cold.
• Freon appears in the freezer only near the evaporator.

⚠️ Attention: Freon leakage is hazardous to health! Inhalation of vapors may cause dizziness and nausea. If you suspect this malfunction - turn off the refrigerator and ventilate the room.

2.2. Capillary tube clogged

The capillary tube is a thin channel through which freon enters the evaporator. Over time, it can become clogged with oil decomposition products or moisture. Symptoms:

• The compressor works, but the refrigerator does not cool or freezes weakly.
• The condenser tube heats up unevenly (one part is hot, the other is cold).
• An oily coating appears on the back wall of the refrigerator oily coating.

Special equipment is required to remove the blockage. It is impossible to do this on your own - contact the service. blowing the system special equipment. It is impossible to do this on your own - contact the service.

2.3. Malfunction of the thermostat or temperature sensor

The thermostat (or electronic sensor in modern models) regulates the inclusion of the compressor. If it breaks, the compressor either does not start or works without stopping. How to check:

1. Disconnect the refrigerator from the network.
2. Remove the thermostat protective cover (usually located next to the light lamp).
3. Check the contacts with a tester: when at room temperature they should be closed.

If the contacts do not close, the thermostat must be replaced. For models with electronic control (Samsung RB37, LG GA-B489), board diagnostics will be required.

2.4. Failure of the start relay

The relay starts the compressor and protects it from overheating. If the relay is faulty, the compressor may:

• Buzz, but not start.
• Click with pauses for 5–10 seconds.
• Heat to high temperatures.

To check relay:

1. Turn off the refrigerator.
2. Remove the relay (usually attached to the compressor).
3. Shake it: if you hear a knock, the magnet has broken off inside, the relay must be replaced.

3. The compressor does not turn on: 3 critical malfunctions

If the compressor does not respond at all turns on the refrigerator, the problem is more serious than a blockage or leak. Here are the three most likely reasons:

3.1. The compressor burned out

The compressor is the “heart” of the refrigerator. If there is an interturn short circuit or a break in the winding, it stops starting. Symptoms:

• The refrigerator does not freeze, the compressor does not hum.
• When you try to turn it on, it works the machine in the panel (if there is short circuit).
• The compressor housing is excessively heated.

To confirm the malfunction you will need continuity of the windings with a tester. If the resistance between the terminals:

• 0 Ohm —short circuit.
• ∞ (infinity) —winding break.

In both cases, the compressor must be replaced. The cost of a new compressor + the work of a technician will be 50–70% of the price of the refrigerator - sometimes it is more profitable to buy new equipment.

3.2. Control board malfunction

In electronically controlled refrigerators (Samsung RL, LG Inverter, Bosch KGE), the board is responsible for starting the compressor. If it breaks down:

• The display does not respond to pressing or shows errors (E1, ER, FF).
• The compressor does not start, although there is power.
• Fans in the system NoFrost do not work.

The board may fail due to voltage surges, moisture or manufacturing defects. Independent repair possible only if you have soldering equipment and a circuit diagram of the board. In other cases, replacement.

3.3. Open circuit. data-i="175">If the refrigerator does not show signs of life (the lamps do not light up, the display does not work), the problem may lie in:

If the refrigerator shows no signs of life (the lamps do not light up, the display does not work), the problem may lie in:

• 🔌 Power cord: Check for kinks or melting.
• 🔧 Terminal block: Inspect the place where the wires are connected to the compressor - they often oxidize contacts.
• ⚡ Fuse: Some models (Atlant, Stinol) have a thermal fuse that trips when overheated.

4. Problems in the NoFrost system: why the upper chamber does not freeze

Refrigerators with the system NoFrost (Samsung RB, LG GA, Beko CN) have additional components that may fail. If the freezer is working but the refrigerator is not, check:

4.1. Fan malfunction

The fan distributes cold air among the chambers. If it is broken:

• The freezer freezes, but the refrigerator does not.
• You can hear inside unusual noise (creaking, crackling).
• Back wall the refrigerator compartment is covered with ice.

To check:

1. Turn off the refrigerator.
2. Remove the back panel in the refrigerator compartment.
3. Try to turn the fan blades by hand - if they do not rotate, it means it is jammed bearing.

4.2. Evaporator freezing

In the system NoFrost the evaporator should automatically defrost. If this does not happen:

• Ice is accumulating on the back wall of the freezer.
• The refrigerator runs non-stop, but does not cool.
• The fan hums, but the air does not circulate.

Cause - breakdown defrost timer or Evaporator heating element. To eliminate:

1. Defrost the refrigerator for 24 hours.
2. Check the resistance of the heating element with a tester (should be 20–40 Ohm).
3. If the heating element is working, replace the defrost timer.

4.3. Broken damper

In two-chamber refrigerators, cold air from the freezer enters the refrigerator compartment through damper. If it is jammed:

• The freezer freezes, but the refrigerator does not.
• It is too warm in the refrigerator compartment or, on the contrary, it freezes the food.

The damper may jam due to:

• 🍂 Ingress of crumbs or ice.
• 🔧 Drive breakdowns (in electronic models).
• ❄️ Icing of guides.

How to check the damper in NoFrost

Open the refrigerator compartment and listen: if the damper is working, you will hear a slight click when the door opens/closes. If there is no sound, the damper is jammed.

5. Problems in drip refrigerators: why the main chamber does not cool

In drip refrigerators (Atlant MHM, Indesit C, Birusa) the cold spreads naturally, without a fan. If your refrigerator is not cooling, check:

5.1. Clogged drainage hole

If the drainage hole is clogged, water does not drain into the pan, but freezes on the back wall. to:

• Formation of an ice “coat”.
• Impaired heat exchange.
• Continuous operation of the compressor.

For cleaning:

1. Turn off the refrigerator.
2. Clean the hole with a cotton swab or wire.
3. Rinse the drainage tube with warm water using a syringe.

5.2. Failure of the thermostat

In drip refrigerators, the thermostat often fails due to oxidation contacts. Symptoms:

• The compressor does not turn on or runs without stopping.
• When you rotate the thermostat knob, you do not hear a click.

To replace the thermostat:

1. Remove the handle and protective casing.
2. Disconnect the wires (take a photo of their location!).
3. Install a new thermostat and connect the wires.

5.3. Freon leak in the evaporator

In drip refrigerators, the evaporator is located on the rear wall. If the tubes are corroded or mechanically damaged, freon leaks. How to determine:

• The compressor works, but the refrigerator does not cool.
• Visible on the back wall oily stains.
• The condenser remains cold.

⚠️ Attention: If the leak occurs in the foamed part of the case, repairs will be expensive - it will require opening the foam layer re-foaming. In such cases, it is often more profitable to buy a new refrigerator.

6. When to call a repairman: 5 signs of a serious breakdown

Not all faults can be repaired yourself. Contact a service center immediately centerif:

• 🔥 Compressor it gets very hot or there is a burning smell coming from it.
• ⚡ When you turn on the refrigerator the machine is triggered in the electrical panel.
• ❄️ On the back wall, ice more than 5 cm thick is formed within a day.
• 💧 It flows from the refrigerator oily liquid (a sign of freon leakage).
• 🔧 The display shows an error E1, ER, FF (in models with electronic control).

The cost of repairs depends on the type of breakdown:

• Replacing the thermostat: 1 500–3 000 ₽.
• Eliminating freon leakage + refilling: 3 500–6 000 ₽.
• Replacing the compressor: 8 000–15 000 ₽.
• Repairing the control board: 4 000–10 000 ₽.

⚠️ Attention: If the refrigerator is under warranty - do not disassemble it yourself! This will void the warranty. Contact an authorized service center of the brand.

7. Prevention: how to avoid breakdowns

To make the refrigerator last longer, follow simple rules:

• 🧊 Defrosting: Even for NoFrost recommended defrosting once a year. For drip models - every 3-6 months.
• 🔌 Voltage stabilizer: Connect the refrigerator through a stabilizer if your network has frequent jumps.
• 🚪 Sealant: Regularly clean the rubber door seal from crumbs and dirt. If deformed, replace it.
• 🍎 Loading products: Do not put hot foods in the refrigerator and do not overload the shelves. - this disrupts air circulation.
• 🧹 Cleaning the condenser: Once every six months, vacuum the grill on the back wall of the refrigerator.

A critical mistake of most users: ignoring the first signs of a malfunction. If the refrigerator freezes worse, but still works, this is the best time for diagnosis. Further operation will lead to failure of the compressor, and repairs will cost an amount comparable to the cost of a new refrigerator.

Frequently asked questions

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

If the light is on and the compressor does not start, check:

1. Thermostat (in mechanical models).
2. Start relay (clicks, but the compressor does not start).
3. Control board (in electronic models).

A freon leak or a break in the compressor winding is also possible.

The freezer works, but the refrigerator does not. What to do?

In two-chamber refrigerators, this is a problem for systems NoFrost. Reasons:

• The damper between the chambers is jammed.
• Blowage fan.
• Evaporator freezing (defrost required).

For drip refrigerators, check the refrigerator thermostat cameras.

The refrigerator hums, but does not freeze. Is it a compressor?

Not always. Possible reasons:

• The compressor is working, but no freon (leakage).
• Clogged in capillary tube.
• Malfunction condenser (does not remove heat).

Check the temperature of the condenser (grid at the back): if it is cold, this is a freon leak.

How long can you store food if the refrigerator is not does it work?

Shelf life at room temperature (20–25°C):

• Dairy products: 2–4 hours.
• Meat and fish: 1–2 hours.
• Vegetables/fruits: 6–12 hours (depending on type).
• Eggs: up to 1 day (in a cool place).

If the refrigerator still cools a little, the food will last longer. Use a cooler bag or ice for temporary storage.

Is it possible to refill freon yourself?

No. To refill freon you need:

• Special. equipment (vacuum pump, pressure gauges).
• Knowledge of the type of freon (for old models - R12, for new ones - R134a or R600a).
• Ability to solder copper tubes (in case of leakage).

Improper refueling can lead to a compressor explosion!
