The situation when Beko refrigerator suddenly stops freezing, but at the same time the light inside continues to burn, always causes panic. This is a classic sign that the electrical power circuit of the outlet is working, but the cooling unit itself is not performing its function. In contrast to the complete lack of reaction of the equipment, here we are dealing with a specific malfunction in the refrigerant circuit or control system.
Owners of models with No Frost and drip system may encounter different symptoms: from a complete lack of cold to an insufficiently low temperature in the main chamber. It is important not to ignore the first signs, such as thawing of food or unusually quiet operation of the motor, since timely diagnosis can save the compressor from an expensive replacement. Below we will analyze in detail the main causes and methods for eliminating them.
Before calling a specialist, it is worth conducting an initial visual diagnosis. Often the problem lies in trivial things that are easy to fix on your own. However, if we are talking about freon leak or complex electronics, specialist intervention becomes inevitable to maintain the warranty and safe operation.
⚠️ Attention: If you heard a loud bang or smelled a burning smell before the refrigerator stopped cooling, immediately unplug the device. Turning it on again without checking the electrical system may result in a short circuit.
Checking the temperature mode and thermostat
The simplest reason why Beko refrigerator does not freeze is that the settings were accidentally changed. Someone in the household could have touched the temperature controller by switching it to minimum cooling or defrosting mode. In electronically controlled models, the failure may have occurred due to a power surge and the system requires a reboot.
The thermostat is a sensor that tells the compressor when to turn on. If it fails, it may “think” that it is already too cold inside and not give the command to start the engine. In mechanical models, this is checked by turning the knob: if the click does not occur even in the extreme position, the element requires replacement. In modern systems, this is responsible for thermal sensor, which is often located behind a plastic panel.
To check the correct operation of the control system, try performing a full reboot cycle. Unplug the device from the outlet for 10-15 minutes. This will allow you to reset errors in the electronic control unit if they were temporary.
If after returning to the factory settings the situation has not changed, you should pay attention to the tightness of the door. A loosely closed door leads to the fact that warm air constantly flows inside, and the unit simply does not have time to cool it, working non-stop. Check if the seal is interfering with anything and if there is a frozen “coat” that prevents the door from closing hermetically.
Diagnostics of the compressor and start relay
Compressor is the heart of the refrigerator, and if it does not start, there will be no cold anywhere. If the light is working and there is no hum of the motor, there is a high probability of problems with the starting relay or the motor itself. The relay is a small plastic block that is put on the contact group of the compressor and is responsible for starting the rotor.
Often the relay fails due to overloads or power surges. Symptoms of a malfunction may include clicking sounds when trying to start or complete silence of the unit. If you have minimal skills in working with technology, you can remove the back cover, carefully remove the relay and shake it. The sound of rattling inside indicates that the insides have crumbled and the part requires replacement.
☑️ Compressor diagnostics
The compressor itself can also burn out, which is a more serious problem. If a humming sound is heard when you turn it on, the motor tries to start, but after a few seconds a click is heard and it goes silent - this is a sign of an interturn short circuit in the winding or wedge of the motor. In this case, you will need to call a technician to replace the motor, since independent repair is impossible without special equipment for soldering and refueling.
⚠️ Attention: Do not try to repair the compressor or start relay if you do not have experience working with high voltage. Residual voltage in the capacitors can be life-threatening even after turning off the device.
Problems with refrigerant and freon leak
One of the most common reasons why Beko refrigerator stopped freezing is a leak refrigerant (freon). Unlike previous cases, the compressor in this situation works normally, often even without interruptions, but there is no cold. This happens because there is no working fluid in the system that transfers heat from the chamber to the outside.
A leak can occur in the places where the tubes are soldered, in the evaporator (especially if it is accidentally pierced with a knife during defrosting) or in the heating circuit of the door perimeter. It is difficult to determine a leak visually, since freon is colorless and odorless. Indirect signs are:
- 🌡️ The compressor works continuously without turning off.
- 🧊 The freezer compartment may freeze, but the main chamber may not (or vice versa).
- 🔊 Change in the sound of the motor (may become quieter or louder usual).
- 💧 The appearance of oily stains on the floor under the back wall of the refrigerator.
If you suspect a leak, under no circumstances leave the refrigerator turned on for a long time. Operating a compressor without a sufficient amount of freon leads to its overheating and eventual combustion. In this case, professional diagnostics using a leak detector are necessary, followed by sealing the leak and refilling the system.
Is it possible to refill a refrigerator with freon yourself?
Independent refilling is impossible without special equipment. The system must be evacuated to remove moisture and air, and the refrigerant must be accurately weighed. Unprofessional refueling will lead to rapid failure of the compressor.
Faults in the No Frost system
In models with the system No Frost the lack of cold when the light is on is often associated with icing of the evaporator. If the defrost system (heating element, timer or defrost sensor) fails, a coat of ice builds up on the evaporator. The fan, which is supposed to drive cold air into the chamber, is jammed with ice or simply cannot blow air through the ice monolith.
As a result, it may be cold in the freezer, but no air flows into the refrigerator compartment. Or the cold does not flow anywhere if the ice has completely blocked the channels. A characteristic sign of such a breakdown is the absence of the characteristic fan noise when the compressor is running.
Diagnostics often require partial disassembly of the rear wall inside the freezer. If you see a thick layer of ice on the evaporator, the defrost cycle is broken. A temporary solution may be to completely defrost the refrigerator within 24 hours, but if the heating element or sensor burns out, the problem will return in a few days.
| Component | Function | Failure symptom |
|---|---|---|
| Heating element defrost | Heats the evaporator to melt the ice | Ice build-up, lack of cold |
| Defrost sensor | Controls the evaporator temperature | No switching on Heating element or its overheating |
| Fan | Cold air circulates | Noise, creaking or complete silence when the motor is running |
| Timer/Board | Controls cooling and defrosting cycles | Chaotic operation of the system, lack of defrosting |
Failures in the electronic control module
Modern refrigerators Beko are controlled by complex electronics. If all the mechanical parts are working properly, the freon is in place, but there is no cold, the problem may lie in the “brains” of the device. The electronic module could fail due to a power surge, moisture or manufacturing defects.
Symptoms of a control board malfunction may include:
- 💡 Flashing indicators on the control panel.
- ❌ Refusal to respond to button presses.
- 🔄 Spontaneous switching on and off of the compressor.
- 📉 Inconsistency between the displayed temperature and the real one.
Module repair requires professional diagnostics using testers and circuits. Often it is necessary to re-flash the chip or replace burnt-out radio components. In some cases, it is cheaper and more reliable to replace the entire control unit with a new one.
When you need to call a technician
Despite the desire to save money, there are situations when DIY repairs are impractical or dangerous. If you've checked the outlet, temperature settings, and made sure the door is closing tightly, but the problem isn't resolved, you'll likely need professional attention. This is especially true for work related to a sealed circuit and high-voltage electrical work.
A master is needed if:
- 🛠️ The compressor needs to be replaced or pipes sealed.
- 💨 A leak is detected refrigerant.
- ⚡ There is a suspicion of a faulty wiring inside the case.
- 🧩 It is necessary to replace the electronic module or complex diagnostics of the sensors.
Remember that independent intervention in the sealed circuit can lead to the final loss of the refrigerator. In addition, the presence of factory seals on the compressor is a condition for maintaining the warranty. If the warranty period has not yet expired, any independent repair will void the manufacturer's obligations.
⚠️ Attention: Specifications and location of parts may vary depending on the specific model Beko. Before starting disassembly, check the technical documentation of your device or the official diagrams on the manufacturer's website.
Prevention and care refrigerator
To avoid situations when Beko refrigerator stops freezing, it is important to follow the operating rules. Regular defrosting (even for No Frost systems once a year), cleaning the drainage hole and checking the seals will prolong the life of the device. It is also important to ensure good ventilation of the back wall, moving the refrigerator away from the wall at least 5-10 cm.
Do not place hot foods in the chamber and do not overload the shelves, which interferes with air circulation. Monitor the condition of the outlet: it should not heat up or spark. Stable voltage in the network is the key to long service life of the electronic components of your unit. Regular maintenance will help you avoid costly repairs and loss of food.
Why does the refrigerator hum but not freeze?
If you hear a hum, it means the compressor is trying to work. Most often, this indicates a freon leak (the system is empty) or a jammed piston group. It is also possible that the circuit in the motor itself is broken, when it hums but cannot start.
Is it possible to operate a refrigerator if it does not freeze?
For a short time - yes, if you are waiting for a technician. However, it is impossible to keep it turned on for a long time if there is a malfunction (especially if there is a freon leak or problems with defrosting). This will lead to the compressor burning out, which will make repairs economically unfeasible.
How long does it take to repair a Beko refrigerator?
Diagnostics usually takes 30-60 minutes. Replacing a thermostat or relay can be done in 1-2 hours. If you need to replace the compressor or find a micro-leak, repairs can take from one to three days, depending on the availability of spare parts and the complexity of the work.
What to do if there is water in the refrigerator, but there is no cold?
Water can be a product of melting ice due to a non-working compressor or problems with defrosting. First check if the motor is working (by hearing and vibration). If the motor is silent, check the relay and thermostat. If it hums, there is probably a freon leak or a clogged capillary tube.
