The situation when Beko refrigerator turns on, buzzes, and the indicators are on, but inside the temperature rises to indoor, is one of the most alarming for the owner. Products begin to deteriorate, an unpleasant odor appears, and it becomes clear that the equipment requires immediate intervention. Users often mistakenly believe that if the motor is noisy, then cold must also be produced, but in modern cooling systems this is not always the case.
The problem can be hidden either in a banal overload of products or in a serious breakdown compressor or a refrigerant leak. Diagnosing a fault requires consistently eliminating simple causes before calling a technician. Understanding the principles of operation of your unit will help you quickly determine the nature of the breakdown.
In this article we will analyze in detail all possible scenarios why Beko it stopped freezing, and what actions you can take yourself, and when professional repairs using special tools are required.
Primary diagnostics and simple causes
Before you panic and look for a service center number, you need to conduct a basic check, which often reveals non-obvious operating errors. Sometimes the reason lies in a violation of heat transfer or incorrect setting of temperature conditions. Overheating The back wall is a frequent companion of cooling problems.
Make sure that there is a gap of at least 5-7 cm between the back wall of the refrigerator and the kitchen wall. If the unit is standing closely, the radiator will not be able to keep up give off heat, and the system goes into a protective cycle or simply cannot cope with the load. Also check whether the air access inside the chamber is blocked by the products.
Particular attention should be paid to the quick freezing mode. If you accidentally activated the function Super Freeze or Quick Cool for a long time, the compressor could wear out and then go into error or simply stop cooling effectively due to overheating.
Faults of the defrost system (No Frost)
In models with the system No Frost most A common reason for the lack of cold when the engine is running is a failure in the evaporator defrost system. Ice builds up on the radiator, blocks the air supply channels, and the cold flow simply does not reach the products, remaining behind the rear panel.
Several key elements are responsible for the defrosting process: defrost timer, heating element (heater), defrost thermostat and defrost sensor. If one of these components fails, the ice “coat” blocks the fan from working. You can hear the motor humming, but there is no air circulation.
- ❄️ The defrosting heating element: The coil burns out, the ice does not melt during the defrost cycle.
- ⏱️ Timer or board: does not send a command to turn on the defrosting mode.
- 🌡️ Defrost thermostat: incorrectly reads the temperature and interrupts the cycle prematurely.
⚠️ Attention: Trying to pick the ice yourself with a knife or sharp objects will lead to a breakdown of the evaporator and an instant leak of freon. This is a fatal failure for the refrigerator.
To check the No Frost system, it is often necessary to completely defrost the unit within 24 hours. If after this the refrigerator worked normally for a couple of days, and then stopped cooling again, the problem is guaranteed to be in one of the elements of the defrost system.
Symptoms of a faulty defrost sensor
If the sensor is “stuck” in the “defrost complete” position, the heating element may turn on constantly or not turn on at all, which leads to either melting of food or icing.
Problems with the compressor and start relay
Compressor - this is the heart of the refrigerator, and if it works but does not create pressure in the system, there will be no cold. It often happens that the motor hums for 10-20 seconds, then a click is heard and it goes silent. This is a classic sign of a malfunction of the start relay or the compressor itself.
The start relay is a small plastic block that fits onto the contact of the compressor. Inside it is a mechanism that helps start the engine. Over time, the contacts burn out or the mechanism jams. Replacing the relay is one of the simplest and cheapest repair procedures.
If the relay is working properly, but the compressor still does not start or runs “idle” (does not compress the gas, but simply circulates it), this may indicate an interturn short circuit of the windings or a loss of performance of the piston group. In this case, replacement of the unit is required.
☑️ Compressor diagnostics
It is worth noting that inverter compressors, which are often found in modern Beko, are diagnosed differently. They do not emit characteristic clicks when starting, but smoothly gain momentum. If the inverter control module is burned out, the compressor may not start at all.
Refrigerant leak and capillary blockage
If the compressor runs continuously without turning off, it hums very loudly, but there is no cold at all - this is a sure sign freon leaks or clogging capillary tube. There is no pressure in the system, and the refrigerant does not circulate through the circuit, without taking heat from the chambers.
Leaks often occur at soldering points, in foamed parts of the body or through microcracks in the evaporator, especially if you have previously tried remove the ice with sharp objects. Freon is odorless and colorless, so it is impossible to detect it visually without special equipment (leak detector).
| Symptom | Freon leak | Capillary clogged |
|---|---|---|
| Compressor operation | Works without stopping | Works without stopping |
| Condenser temperature | Cold or partially warm | Hot before blockage, cold after |
| Sound | Monotonous hum | Gurgling, hissing |
| Repair | Search for leaks, soldering, refilling | Purge the system, replace the filter |
It is impossible to eliminate these faults on your own. You need to call a technician with a vacuum pump, a pressure gauge station and a supply of freon. Refilling a refrigerator is a technologically complex process that requires precise adherence to dosages and evacuation of the system.
Malfunctions of the thermostat and electronics
In mechanical models Beko the thermostat is responsible for maintaining the temperature. If its bellows tube has lost sensitivity or the contacts have oxidized, a signal to start the compressor may not be received, or, conversely, the compressor will not receive a signal to stop (which leads to the previous point about continuous operation).
In models with electronic control (Electro Control), the role of a thermostat is performed by temperature sensors (NTC). They are located at different points: in the freezer, in the refrigerator compartment, on the evaporator. The failure of one sensor can block the operation of the entire cooling system.
- 🔌 Contacts: oxidation in the sensor wiring connectors.
- 💻 Module controls: a burnt triac on the board does not supply voltage to the compressor.
- 📟 Display: no indication or error code (for example, E0, E1) will indicate a specific node.
Diagnostics of electronics often requires testing sensors with a multimeter at different temperatures. The resistance of a working sensor should change smoothly. If the device shows an open circuit or short circuit, the element must be replaced.
⚠️ Attention: Before replacing any electrical components, be sure to disconnect the refrigerator from the network. Working under voltage is life-threatening and can permanently damage the control board.
When you need to call a technician
Not all breakdowns can be repaired with your own hands. If you have checked simple reasons, done defrosting, but the situation has not changed, most likely a complex repair is required. Sealed circuit The refrigerator is a system that does not tolerate amateurish intervention.
A technician is needed if you need to replace the compressor, search for leaks, refill with freon or repair electronic fees. These works require special tools: a burner, a vacuum sealer, and testers. Trying to do this “on the knee” will only lead to an increase in the cost of repairs in the future.
In addition, a professional technician will be able to accurately diagnose rare faults, for example, a micro-leak through a capillary tube or a malfunction in the control module of an inverter compressor that cannot be detected visually.
Repair cost
Replacing a thermostat or relay is usually inexpensive, while replacing a compressor or finding a leak in the foamed part can amount to up to 50-70% of the cost of a new refrigerator.
Prevention and care of a Beko refrigerator
So that Beko refrigerator serves for a long time and does not let you down the most inopportune moment, it is important to follow the operating rules. Regular defrosting (even for the No Frost system once every year or two) helps extend the life of the compressor and maintain the efficiency of heat transfer.
Keep the condenser grill at the back clean. Dust and pet hair act as a heat insulator, forcing the engine to work at its limit. You need to vacuum the grille at least once every six months.
Also, do not overload the chambers with products. Cold air should circulate freely. If you fill the shelves to capacity, the fan will run idle, and the temperature in different corners of the chamber will vary greatly.
Frequently asked questions (FAQ)
Why does the Beko refrigerator hum, but does not freeze after defrosting?
If after 24 hours of defrosting the cold does not appear, The problem is probably not an ice jam. Most likely, there was a freon leak (gas could escape through a microcrack while the system was passive) or the compressor/relay failed. Diagnostics by a specialist is required.
Is it possible to operate a refrigerator if it does not cool?
For a short time - yes, for storing vegetables at room temperature. But you cannot leave it turned on in this state for a long time: the compressor will work without rest, which will lead to its overheating and burnout of the windings. It is better to turn off the device before repair.
What refrigerant is used in Beko refrigerators?
In modern models it is most often used R600a (isobutane). This is an explosive gas, so repair of a system with a leak (soldering, refilling) should only be carried out by a specialist in a well-ventilated area.
What does the flashing temperature indicator on Beko mean?
A flashing indicator usually signals an increase the temperature in the chamber is higher than the permissible norm. If you just turned on the refrigerator or loaded a lot of warm food, this is normal. If the blinking continues for a long time when the shelves are empty, this is a malfunction code.
