The situation when a refrigerator Beko buzzes without interruption is familiar to many owners of this popular Turkish appliance. Instead of the usual cycle of operation, followed by a period of silence, the unit continues to operate in an enhanced mode, trying to achieve the set temperature indicators. This not only leads to increased energy consumption, but also creates a significant load on the compressor, which can cause its rapid failure.
Continuous operation of the compressor often indicates that the system thermoregulation has failed or the tightness of the circuit has been compromised. In some cases, the problem lies in trivial operating errors that are easy to fix yourself. However, ignoring alarm signals in the form of a continuous hum can lead to expensive repairs.
In this article we will look in detail at why the refrigerator Beko does not turn off, and what actions need to be taken to resolve the problem. We will consider both external factors and complex technical breakdowns that require specialist intervention.
Incorrect installation and violation of temperature conditions
The first thing you need to check if your refrigerator stops turning off is the conditions of its placement. Units Beko, like any other equipment, require free space for air circulation around the radiator grille. If the refrigerator is pushed close to the wall or side cabinets, the heat is not removed effectively, and the compressor is forced to work non-stop.
It is also worth paying attention to the temperature in the room. If the kitchen is overheated, for example in the summer or due to a running stove, the cooling system has a harder time keeping up with the load. In hot weather, it is normal to increase the operating time of the compressor, but it must still stop periodically.
⚠️ Attention: The minimum distance from the back of the refrigerator to the wall should be at least 7-10 centimeters. Ignoring this rule will lead to overheating of the motor.
Another common reason is setting the temperature too low. If you set the mode Super Freeze or minimum values on the thermostat, the equipment will work non-stop. For normal storage of food, a temperature of +4...+5°C in the main chamber is sufficient.
Check the door for tight seal. If the sealing rubber is dirty or damaged, warm air constantly enters the chamber. Sensors detect the temperature increase and give the command to the compressor to continue working. It is enough to wipe the seal with a soft cloth and soapy water to fix the problem.
Malfunctions of the defrost system and ice freezing
In models Beko with the system No Frost or Low Frost the condition of the system is critical defrost. If the evaporator is covered with a thick crust of ice, the cold stops circulating normally through the chambers. The fan moves the air, but it does not cool to the required temperature, and the refrigerator works without interruption.
The main culprits here are often:
- ❄️ defrost heating element —a heating element that could burn out and stop melting the ice.
- ⏱️ Defrost timer - a mechanism that does not switch the refrigerator to defrost mode.
- 🌡️ Defrost sensor - a sensor that erroneously tells the controller that there is no ice.
Diagnostics often require a complete defrost of the unit. Leave the refrigerator turned off for 10-12 hours with the doors open. If, after turning on in normal mode, the equipment started working correctly and began to turn off, then the problem lies precisely in the defrosting system.
If after defrosting the situation repeats after 1-2 weeks, you need to call a technician to replace the burnt-out element of the system. It is not recommended to climb inside the case yourself without skills, as you can damage fragile plastic parts or wiring.
Refrigerant leak and problems with the compressor
One of the most serious reasons why Beko refrigerator does not turn off is a freon leak. The refrigerant circulates in a closed circuit and transfers heat. If a microcrack has formed in the tubes (often due to corrosion or mechanical damage), the gas gradually evaporates.
If there is a lack of freon, the pressure in the system drops. The compressor tries to compensate for the lack of cold by working at the limit of its capabilities. A characteristic sign of a leak is that the motor is hot, and the chambers are warm, or cold only near the evaporator.
| Symptom | Probable cause | Action |
|---|---|---|
| Compressor is hot, cold is weak | Freon leak | Call a technician, search for leaks, refuel |
| There is a buzzing sound, no cold | Clogged capillary tube | Purge the system, replace the filter |
| The engine gets very hot and clicks | Faulty start relay | Replacing the relay |
It is important to understand that refilling with freon is not just “topping up gas.” It is necessary to find the leak, solder it and only then refill the system. If you simply add refrigerant, after a short time it will evaporate again, and the compressor will burn out due to dry operation.
Is it possible to refill the refrigerator yourself?
Refilling it yourself with freon at home is extremely difficult and dangerous. Requires a vacuum pump, a pressure gauge station and precise knowledge of the type and amount of refrigerant (R600a is explosive). An error will lead to complete breakdown of the compressor.
Another problem may be Clogged capillary tube. The refrigerant circulation system has a filter-drier that retains moisture and microparticles. Over time, it becomes clogged and freon stops circulating normally. The symptoms are similar to a leak: the refrigerator hums, but does not freeze.
Failure of the thermostat and temperature sensors
The thermostat (temperature regulator) is the “brain” that makes decisions about turning on and off compressor. Older models Beko use mechanical thermostats, while new ones use electronic sensors. If this element fails, it can send the wrong signal that the chamber is too warm.
In mechanical models, the failure is often associated with a loss of seal in the bellows tube, which is filled with a temperature-sensitive gas. The tube is attached to the evaporator inside the chamber. If the gas has evaporated, the thermostat contacts remain closed and the motor runs constantly.
Electronic temperature sensors (NTC sensors) are also susceptible to failure. They can give erroneous resistance readings, causing the electronic control module to not command the engine to stop. Diagnosis of such faults is carried out using a multimeter.
⚠️ Attention: Before replacing the thermostat, be sure to disconnect the refrigerator from the power supply. Working with live electrical components is life-threatening.
Replacing the thermostat is a procedure that can be done with your own hands if you have basic skills. It is necessary to remove the old device, noting the length and position of the capillary tube, and install a new one with similar markings. Electronic sensors often require access to the rear wall of the evaporator.
Problems with the control module and relays
Modern refrigerators Beko are controlled by complex electronics. The control board analyzes data from all sensors and regulates the operation of the compressor, fans and heating elements. If the motor control triac on the board burns out or a software failure occurs, the compressor may go into constant operation.
Often the culprit is the start-up relay. This device starts the engine and protects it from overloads. If the relay contacts burn out or “stick” in the closed state, current continues to flow to the compressor windings even when it is not needed.
Signs of a malfunctioning module or relay:
- 🔥 The compressor runs continuously and gets very hot.
- 💡 On the control panel there may be indicators flash or an error light comes on.
- ⚡ Relay clicks are heard, but the engine does not start or stop.
Diagnostics of the electronic module requires special knowledge and equipment. At home, you can visually inspect the board for blackening, swollen capacitors, or a burning smell. However, it is better to entrust the repair of the board to professionals, since it requires re-soldering of components and configuration.
☑️ Diagnostics before calling a technician
Inverter compressors: normal or broken?
Owners refrigerators Beko s inverter compressor it is worth knowing one important feature. Unlike classic models, which turn on and off, inverter motors work constantly, but with different power. They do not turn off completely, but only reduce the speed to maintain the temperature.
Therefore, if your new refrigerator hums quietly and continuously, but the food is well frozen, and it is cold inside the chambers, this is not a breakdown, but normal operation. Inverter systems are more energy efficient and make less noise.
However, if the inverter refrigerator begins to hum louder than usual, the temperature in the chambers has risen, or an error appears on the display, this is a signal of a malfunction. The inverter control unit may have failed, or the compressor itself needs to be replaced.
⚠️ Attention: Inverter compressors are very sensitive to voltage surges. It is recommended to connect such refrigerators through a voltage stabilizer to avoid costly repairs.
To accurately determine the type of compressor, look at the technical data sheet or the sticker on the back of the unit. It will say "Inverter" or "Linear". If you have a regular model, and it works non-stop, this is definitely a malfunction.
Frequently asked questions (FAQ)
How long should a Beko refrigerator work normally?
In normal mode, the operating cycle is approximately: 15-20 minutes of work and 30-40 minutes of rest. The ratio of operating time to stopping time should be approximately 1:2 or 1:3. If the refrigerator works more than it costs, and at the same time it is warm inside, this is a sign of a malfunction.
Can the refrigerator not turn off due to the heat in the summer?
Yes, in the summer, when the room temperature is above +30°C, the compressor operating time increases. However, it should still turn off periodically. If the room is very hot, try to ventilate the kitchen or do not place heating devices near the refrigerator.
What to do if after defrosting the refrigerator does not turn off again?
If complete defrosting (24 hours) did not help, then the problem is not in the ice, but in a technical malfunction: a freon leak, a broken thermostat or compressor. In this case, you need to contact a service center for professional diagnostics.
Is it dangerous if the refrigerator runs continuously for 24 hours?
Yes, it is dangerous. The compressor is not designed for 24/7 operation without rest. Under such a load, it overheats, the oil in the system loses its properties, and the motor may burn out. If continuous operation is detected for more than 6-8 hours, it is better to turn off the device and call a technician.
