Is your refrigerator Beko humming, the light inside is on, and the food in the freezer is melting? The situation when the equipment “works, but does not freeze” is one of the most insidious. On the one hand, the compressor turns on, which means there is power, but on the other hand, the temperature in the chambers is far from normal. In 80% of cases, the problem is solved without calling a technician, if the cause is correctly identified.
In this article we will analyze 7 main reasonswhy the refrigerator Beko (models CNA 335 K20, DS 331020, GNE 114220 and others) stops freezing when the compressor is running. You will learn how to check thermostat, fan i refrigerant circulation system without special tools, and also when exactly it is time to call a service engineer. We will pay special attention to the “symptoms” that will help distinguish a breakdown from a temporary failure.
⚠️ Important: If refrigerator Beko with a system No Frost, the diagnostic algorithm will differ from models with drip defrosting. More on this in a separate section.
1. Clogged capillary tube: how to recognize and eliminate
The capillary tube is the “artery” of the refrigerator through which refrigerant (freon) circulates. If it becomes clogged oil deposits, metal shavings or with moisture, freon cannot move freely and the freezer stops cooling. At the same time, the compressor works for wear, trying to “push” the refrigerant through the blockage.
Signs of capillary blockage:
- 🔊 The compressor runs without stopping or turns on too much often (every 5-10 minutes).
- ❄️ The condenser (grid on the back wall) is cold, although it should heat up.
- 🌡️ The temperature in the refrigerator compartment is higher than normal, in the freezer it is slightly lower, but not sufficient for freezing.
To confirm the blockage, touch filter drier (the metal cylinder next to the compressor). If it hot at only one point or cold, this is a sure sign of a problem. It is impossible to clean the capillary tube on your own - you will need evacuating the system refilling with freon. But you can temporarily “reanimate” the refrigerator:
Disconnect the refrigerator from the network for 12-24 hours (let the oil drain)|Check that does the compressor heat up immediately after switching on|Inspect the condenser for ice or rust|If the problem persists, call a technician to clean the system-->
⚠️ Attention: Do not try to “blow out” the capillary tube with a compressor or pump! This can lead to rupture of the system or moisture getting inside, which will aggravate the breakdown.
2. Failure of the thermostat (thermostat): how to check
The thermostat is the “brain” of the refrigerator, which controls the temperature and sends signals to the compressor. If it fails, the compressor either runs continuously or does not turn on at all. In models Beko (CN 328220, DS 331020, the thermostat is often located inside the refrigerator compartment, next to the lamp.
How to check the thermostat:
- Unplug the refrigerator.
- Remove the thermostat protective cover (usually secured with latches or screws).
- Find two wires going to the thermostat and connect them to each other (for example, using a screwdriver with an insulated handle).
- Turn on the refrigerator. If the compressor starts working, the thermostat is faulty.
If the thermostat “sticks” in the “off” position, the compressor will not start at all. If it is stuck in the "on" position. — the compressor will work without stopping, but will not freeze (due to incorrect signals). Replacing the thermostat will cost 1 500–3 000 ₽ depending on the model.

3. Freon leak: signs and what to do
Freon is a refrigerant that circulates through the system and provides cooling. If a crack appears somewhere in the circuit (most often in evaporator or condenser), freon leaks out and the refrigerator stops freezing. In this case, the compressor works, but without results.
Signs of freon leakage:
- 🕳️ Oil stains are visible on the back wall of the refrigerator (freon leaks out along with oil).
- ❄️ The condenser (grid at the back) remains cold even after an hour of compressor operation.
- 🔧 The compressor turns on for 1-2 minutes and immediately turns off (overheating protection).
It is impossible to eliminate the leak on your own - required soldering the circuit, evacuating i filling with freon. But you can localize the leak location:
- Inspect weld seams on condenser and evaporator.
- Check for leaks filter drier (cylinder next to the compressor).
- If refrigerator No Frost, inspect evaporator tubes (they can corrode due to condensation).
⚠️ Attention: Freon has no smell and color, so a leak can only be detected by indirect signs or with the help leak detector (a device that craftsmen have). Do not try to “refuel” the refrigerator yourself - this is dangerous to your health!
4. Problems with the fan in No Frost refrigerators
If your Beko equipped with a system No Frost (GNE 114220, CNFE 5164 etc.), then the fan is responsible for the circulation of cold air. If it breaks, the freezer stops cooling, although the compressor is running. Reasons for fan failure:
- 🍂 Ice on the blades (due to a faulty defrost heater).
- 🔌 Broken motor winding.
- 🛠️ Mechanical blockage (for example, a piece of cling film got into blades).
How to check the fan:
- Unplug the refrigerator.
- Remove the back panel in the freezer (usually secured with screws).
- Try to turn the fan blades by hand. If they do not rotate, the problem is a mechanical blockage or a motor failure.
- Connect the refrigerator to the power supply and listen: if the fan does not make noise after 10-15 minutes of operation, it is faulty.
If the fan is blocked by ice, defrost the refrigerator for 24 hours. If the problem is in the motor, it will have to be replaced (the cost of the spare part is from 2 000 ₽).
5. Compressor malfunction: when You can’t do without a technician
The compressor is the “heart” of the refrigerator. If it is does not create the required pressure or works intermittently, the refrigerator will hum, but not freeze. In models Beko compressors often fail due to:
- 🔥 Overheating (if the refrigerator is close to the wall or radiator).
- ⚡ Power surges (especially important for dachas and old houses).
- 🛢️ Wear of the piston group (if the refrigerator is more than 10 years old).
How to check the compressor:
| Symptom | What does this mean | Solution |
|---|---|---|
| The compressor hums, but does not start | Interturn short circuit or faulty starting relay | Replacement of the relay (~1,000 ₽) or compressor (~8,000–15,000 ₽) |
| The compressor turns on for 1-2 seconds and turns off | Overheat protection (the winding may have burned out) | Diagnostics with a multimeter, replacement compressor |
| The compressor is hot, but the refrigerator does not freeze | Insufficient pressure (wear or leakage of freon) | Checking with a pressure gauge, refilling or replacing the compressor |
⚠️ Attention: If the compressor does not turn on at all, first check start relay (black box on the compressor). Sometimes it is enough to replace it for the refrigerator to work.
6. Failure of the electronic control module
In modern models Beko (GNE 124220, CNFE 5164) is responsible for the operation of all systems. electronic control unit. If it fails, the compressor may operate, but no cooling signals are received. Causes of failure:
- ⚡ Power surge.
- 💧 Moisture ingress (for example, during defrosting).
- 🛠️ Short circuit in circuit.
Symptoms of module malfunction:
- 📛 An error flashes on the display (for example,
E1,E3—the explanation is in the instructions). - 🔄 The compressor turns on chaotically, without connection with the temperature.
- 🔇 The refrigerator does not respond to button presses.
It is impossible to repair the module yourself - you need reflashing or board replacement (cost - from 3,000 to 6,000 ₽). If the refrigerator is under warranty, contact the service center Beko.
How to reset the error on the display?
In some models Beko the error can be reset by simultaneously pressing the Super Cool and Super Freeze buttons for 5-10 seconds. If the error appears again, the problem is not a failure, but a breakdown.
7. Door seal and other “little things” with big consequences
Sometimes the refrigerator Beko does not freeze due to leaky door or clogged drainage system. These problems seem minor, but lead to serious consequences:
- 🚪 Wear of the seal: If the rubber on the door is cracked or deformed, warm air gets inside and the compressor cannot cope with the load.
- 💧 Clogged drainage hole: Water accumulates under the drawers, ice forms, which blocks air circulation (relevant for No Frost).
- 🌡️ Incorrect installation: If the refrigerator is not level, the door warps and poor closes.
How to check and fix:
- 📏 Seal: Close the door, insert a sheet of paper between the seal and the body. If the sheet pulls out easily, the seal needs to be replaced.
- 🔍 Drainage: Clean the hole at the bottom of the refrigerator compartment with a wire or a syringe with warm water.
- 📐 Level: Adjust the legs of the refrigerator so that it stands level (check with a building level).
⚠️ Attention: If the seal is dirty, you can try it restore: wash with soapy water, lubricate with silicone grease and heat with a hairdryer (so that the rubber becomes elastic - only replace it!
FAQ: Frequently asked questions about Beko refrigerators that do not freeze
Is it possible to refill a refrigerator with freon yourself?
No. To refill you need special tool (a vacuum pump, a pressure manifold, a cylinder with freon) and skills in working with refrigerants. Incorrect refilling can lead to circuit rupture or poisoning (freon is toxic when heated). Contact a specialist.
The Beko No Frost refrigerator does not freeze, but the fan is working. What's the matter?
Most likely, the problem is in defrost heater or temperature sensorin the systems No Frost the fan can spin, but if the evaporator iced up, cold air does not enter the chambers. Try defrosting the refrigerator for 24 hours. If this does not help, you need diagnostics.
How much does it cost to repair a Beko refrigerator if it does not freeze?
The cost depends on the reason:
- Thermostat replacement - 1 500–3 000 ₽.
- Compressor repair - 8 000–15 000 ₽.
- Freon leak elimination + refilling - 4 000–7 000 ₽.
- Electronic module replacement - 3 000–6 000 ₽.
If the refrigerator is more than 7-10 years old, sometimes it is more profitable to buy a new one.
After defrosting, the Beko refrigerator stopped freezing. What should I do?
Probable reasons:
- Moisture has entered the system (you need to vacuum and refill with freon).
- The defrost heater has burned out (in models No Frost).
- The thermostat or relay contacts have oxidized (check and clean).
Do not turn on the refrigerator immediately after defrosting - let it stand for 1-2 hours at room temperature.
Can a Beko refrigerator not freeze due to a power surge?
Yes. Voltage surges most often damage:
- 🔌 Electronic control module (board).
- ⚡ Compressor (winding burns out).
- 📛 Temperature sensors.
If the voltage in your area is unstable, use stabilizer or surge filter for the refrigerator.
