Have you opened the refrigerator, and the food in the main chamber is warm, although the freezer is working as usual? This is a common problem faced by owners of equipment Atlant, Samsung, Indesit and other brands. In 80% of cases, the malfunction is associated with a breakdown of the cooling system or electronics, but sometimes banal operating errors are to blame.
In this article we will analyze 7 main reasonswhy the refrigerator stopped cooling, mientras que the freezer is functioning normally. You will learn how to diagnose the problem yourself, which parts most often fail, and in which cases you cannot do without calling a specialist. We will also give step-by-step instructions for troubleshooting simple problems - from defrosting to checking the thermostat.
Let us warn you right away: if your refrigerator has a system No Frost, the troubleshooting algorithm will differ from models with drip defrosting. This is important to consider when diagnosing.
1. Capillary tube clogged: why the refrigerator does not cool
The capillary tube is a thin copper channel through which the refrigerant (freon) flows from the condenser to the evaporator. If it becomes clogged the freezer continues to work, but the main chamber remains warm. The cause of blockages is the entry of moisture, oil or small particles into the system.
How to recognize the problem:
- 🔍 The compressor runs non-stop or turns on too often
- ❄️ The freezer freezes food and forms thick layer of ice
- 🌡️ The temperature in the refrigerator compartment does not fall below +10...+15°C
It is impossible to clean the capillary tube on your own - you will need special equipment (vacuum pump, pressure gauges) and experience. If you suspect a blockage, it is better to call a professional immediately. However, you can check indirect signs:
Touch the condenser (the grill at the back of the refrigerator) - if it is cold, this is a sign of poor freon circulation|
Listen to the compressor: when clogged, it works louder than usual, with vibration|
Check if the freezer evaporator is not covered with a thick layer of frost (more than 5 mm)-->
⚠️ Attention: Do not try to clean the tube with wire or blow it with a compressor! This will lead to system damage and freon leakage. The work must be performed by a certified specialist with a license to handle refrigerants.
2. Malfunction of the temperature regulator (thermostat) of the fridge compartment
The thermostat is a sensor that monitors the temperature in the fridge compartment and sends a signal to the compressor to turn on/off. If it breaks, the compressor either does not receive a command to cool the main chamber or does not work correctly.
Signs of a thermostat failure:
- 📉 The temperature in the refrigerator is increased, but in the freezer it is normal
- 🔄 The compressor turns on rarely or does not turn off at all
- 💡 The light inside the chamber is on, but there is no cooling
- 🔧 When you turn the thermostat knob, you cannot hear a click (characteristic operation sound)
How to check the thermostat yourself:
- Disconnect the refrigerator from the mains and take out everything products.
- Remove the thermostat protective cover (usually it is located next to the light bulb or on the back wall of the chamber).
- Disconnect the wires from the thermostat and short them together (simulating a closed state).
- Turn on the refrigerator - if the compressor starts working, the thermostat is faulty.
The cost of a new thermostat for popular models (Samsung RL-34, Atlant MXM-180, LG GA-B409) is from 800 to 2500 rubles. You can do the replacement yourself if you are confident in your skills. The main thing is do not mix up the wires when connecting!
3. Freon leak: why the freezer works but the refrigerator does not
Freon is a refrigerant that circulates through the system and provides cooling. If a leak occurs, its quantity decreases and the compressor cannot fully cool both chambers. Most often the freezer continues to workbecause it is closer to the compressor and receives residual freon.
Causes of leakage:
- 🛠️ Mechanical damage to the tubes (for example, when moving the refrigerator)
- 🔥 Corrosion of copper tubes due to high humidity
- 🧊 Microcracks in solder joints (often found in refrigerators older than 10 years)
How to recognize a leak:
| Symptom | What occurs | Additional symptoms |
|---|---|---|
| The compressor works non-stop | Tries to compensate for the lack of freon | The compressor housing heats up |
| Condenser (grid at the back) cold | Freon does not circulate fully | Icing of the tubes may occur |
| The freezer does not freeze well | Freon is only enough for partial cooling | The temperature in the freezer is above -12°C |
| Oil stains on the floor under the refrigerator | Oil has leaked from the compressor (often accompanies a freon leak) | Smell of burning or chemicals |
⚠️ Attention: Freon is harmless to humans, but if there is a leak in the room, gas can accumulate, displacing oxygen. If you smell a chemical smell, ventilate the kitchen and do not turn on the refrigerator until repairs.
The leak can only be repaired at a service center. The technician will find the location of the damage, solder the tube and fill the system with new freon. The average cost of repairs is from 3,500 to 7,000 rubles, depending on the model and amount of work.

4. No Frost fan failure: why the cold does not blow
If your refrigerator is equipped with a system No Frost, the problem may lie in the fan that distributes cold air between the chambers. When it breaks, the freezer continues to freeze (since the evaporator is located next to it), and the refrigerator compartment remains warm.
Causes of fan failure:
- 🍂 Clogged blades with ice or dust
- 🔌 Motor malfunction fan
- 🧊 Icing of the evaporator (due to a malfunction of the defrost heating element)
- 🔋 Power problems (fuse blown or contacts oxidized)
How to check the fan:
- Disconnect the refrigerator from network.
- Remove all food from the freezer and remove the back panel (in most models it is secured with latches or screws).
- Try turning the fan blades by hand - if they do not rotate or make a squeaking sound, the problem is in the bearings.
- Turn on the refrigerator and listen - if the fan is not making noise, which means it is not working.
If the fan is blocked by ice, defrost the refrigerator for 12-24 hours. If the problem is in the motor, a replacement will be required (the cost of the part is from 1,500 to 4,000 rubles). In 30% of cases, defrost timer or Evaporator heating element is to blame - they also need to be checked.
What will happen if you don’t fix the No Frost fan?
If you ignore the breakdown, the ice on the evaporator will build up until it completely blocks the air circulation. This will lead to overheating of the compressor and its failure. In the worst case, the compressor will need to be replaced (from 8,000 rubles).
5. Malfunction of the solenoid valve (for two-compressor models)
In refrigerators with with one compressor and two chambers, the solenoid valve is responsible for the distribution of cold. It switches the flow of freon between the freezer and refrigerator. If the valve jams or its winding burns out, the cold stops flowing into the main chamber.
Symptoms of valve malfunction:
- 🔄 The freezer freezes too much and the refrigerator does not cool
- 🔊 There are no clicks when switching the valve
- 🌡️ The temperature in the refrigerator rises to room temperature
How to check the valve:
- Turn off the refrigerator and remove the back cover (in most models the valve is located next to compressor).
- Check whether voltage is supplied to the valve coil (you need a multimeter).
- Try to manually switch the valve - if it does not move, it means it is jammed.
The cost of a new valve is from 1200 to 3000 rubles. Replacement requires soldering work, so it is better to entrust it to a professional. If the valve is working properly, but does not work, the problem may be in the control unit.
6. Problems with the door seal: why warm air gets inside
If the rubber seal on the refrigerator door is worn out or dirty, warm air gets inside and the temperature rises. At the same time, the freezer continues to work normally, since its door is sealed.
How to determine that the seal is to blame:
- 📏 A gap of more than 2 mm is visible between the door and the body
- 🧽 The rubber is sticky, with cracks or peels off
- 💧 Condensation accumulates on the back wall of the refrigerator
- 🔍 When the door is closed, the light inside is on (which means the contacts do not work)
How to fix the problem:
- Clean the seal warm water and soap, then wipe with ammonia (this will restore elasticity).
- If the elastic band is deformed, try adjust the door - sometimes it helps to tighten the hinges.
- Check sealing using a sheet of paper: close the door by clamping the sheet - if it pulls out easily, the seal needs to be changed.
The cost of a new seal is from 500 to 2000 rubles. Replacement does not require special skills: the elastic band is attached with glue or in a groove. The main thing is to choose the right model for your refrigerator (Bosch KGE39XW25R, Samsung RB-30 J3200EF etc.).
7. Failure in the control unit: when the electronics fail
Modern refrigerators are equipped with electronic boards that control the operation of all systems. If the control unit fails, it may distribute cold incorrectly, ignore sensor signals, or completely turn off cooling of the refrigeration chamber.
Signs of electronics failure:
- 📱 The display shows errors (for example,
E1,F2,H1—see the instructions for decoding) - 🔄 The refrigerator turns on/off spontaneously
- 🎛️ Does not respond to changes in temperature settings
- 💡 Indicators light up chaotically or do not light up at all
What to do:
- Disconnect the refrigerator from the network for 10-15 minutes, then turn it on again (sometimes a reboot helps).
- Check whether the contacts on the board have oxidized (if you have access).
- If an error appears on the display, find its explanation in the instructions or on the manufacturer's website.
⚠️ Attention: Do not try to repair the board yourself if you do not have experience working with electronics! Improper soldering or shorting of contacts can completely damage the refrigerator. The average cost of repairing a control unit is from 2000 to 6000 rubles.
In 20% of cases, the problem lies not in the board itself, but in temperature sensorsthat send incorrect signals to it. They also need to be checked with a multimeter.
What to do if the refrigerator does not cool: step-by-step plan
Before calling a technician, follow these steps:
Check whether the refrigerator door is tightly closed cameras|
Make sure that the refrigerator is not close to the wall (you need at least 5 cm for ventilation)|
Unplug the refrigerator for 1 hour, then turn it on again (sometimes helps with ice blockages)|
Listen if the compressor is running (should be quiet buzz)|
Check whether the light inside the camera is on (if not, there is a power problem)-->
If simple measures did not help, use this table for further action:
| Symptom | Probable cause | Actions |
|---|---|---|
| The compressor works non-stop, the freezer freezes | Clogged capillary tube or freon leak | Call a technician for diagnostics |
| The refrigerator does not cool, but the light inside is on | Malfunction of the thermostat or temperature sensor | Check the thermostat with a multimeter or close the contacts |
| The freezer is working, the refrigerator is warm, the fan is not making noise | No Frost fan failure | Defrost the refrigerator for 24 hours, if that doesn’t help, replace the fan |
| The temperature in the refrigerator is rising, there is an error on the display | Failure of the control unit or sensors | Reboot the refrigerator, if the error remains, call a technician |
If your refrigerator is under warranty Do not disassemble it yourself this may be the reason for refusal of free repairs. Contact an authorized service center of the brand (Indesit, Beko, Haier etc.).
FAQ: Frequently asked questions about a non-working refrigerator
Is it possible to use a refrigerator if only the refrigerator compartment does not work?
Yes, but with caution. The freezer will function normally, but:
- Do not store perishable foods in it (dairy, meat, ready meals) - they may spoil due to frequent openings.
- Do not load the freezer more than 70% - this will increase the load on the compressor.
- Defrost the freezer regularly to avoid icing.
If the problem is in the thermostat or seal, you can use the refrigerator until it is repaired. If the compressor or freon leak is to blame, it is better not to risk it and turn it off.
How much does it cost to repair if the refrigerator does not cool, but the freezer works?
The cost depends on the cause of the breakdown:
- Replacing the thermostat — 800–2500 rubles. (including work).
- Cleaning the capillary system + refilling freon — 3500–7000 rubles.
- Replacement of the No Frost fan — 1500–4000 rubles.
- Repair of the control unit — 2000–6000 rubles.
- Replacement of the compressor —8000–15000 rubles.
In the regions, prices can be 10–20% lower than in Moscow or St. Petersburg. The technician will tell you the exact cost after diagnostics.
How to defrost a No Frost refrigerator if it does not cool?
Instructions for models with Full No Frost (for example, Samsung RB-37 J5240SA, LG GA-B489 YDQZ):
- Unplug the refrigerator.
- Remove all products and shelves.
- Leave the doors open for 12-24 hours (depending on the degree of icing).
- Place a tray to collect water or put towels.
- After defrosting, wipe the internal surfaces with a dry cloth.
- Turn on the refrigerator and let it work for 2-3 hours without loading food.
⚠️ Do not use a hair dryer or other heating devices to speed up the process - this can damage the plastic and seals!
Why does the refrigerator not cool after defrosting?
Possible reasons:
- Fan No Frost blocked by ice - defrost again for 12 hours.
- Failed Heating element defrost -replacement required.
- Burned fuse fan - check it with a multimeter.
- Problems with defrost sensor - it can give incorrect signals to the board.
If the problem remains after repeated defrosting, call a technician to diagnose the system No Frost.
How to check if the compressor is working in the refrigerator?
Checking methods:
- Aurally: Put your ear to the back wall of the refrigerator. The operating compressor produces a uniform hum. If you hear clicks or silence, it is faulty.
- To the touch: Touch the compressor (black cylinder at the bottom back) - if it is cold, it means it is not working. A hot or warm compressor indicates normal operation.
- With a multimeter: Turn off the refrigerator, remove the cover from the compressor and check the resistance of the windings. Normal values are 20–50 Ohms (see the technical data sheet for exact data).
If the compressor does not turn on, check start relay (black box next to the compressor). Often the problem lies in it, and not in the compressor itself.
