The situation when the Beko refrigerator works continuously without pausing causes concern for any owner. This is not just unnecessary noise that prevents you from sleeping at night, but also a direct threat to the safety of the products and the unit itself. Constant operation of the compressor leads to overheating of the components, accelerated engine wear and a sharp increase in electricity bills.
In most cases, the reason lies in a violation of heat exchange or a refrigerant leak, although sometimes the problem is solved by simply adjusting the thermostat. It is important not to ignore the first symptoms, since long-term operation in non-stop mode it can destroy an expensive compressor in a matter of days.
Next we will analyze in detail the main reasons why your refrigerator does not turn off and determine what steps need to be taken right now. You will learn to distinguish software failures from serious mechanical breakdowns.
Incorrect setting of the Super Freeze mode
The most common and easily eliminated reason for the endless operation of the refrigerator is the accidentally activated mode Super Freeze (Super Freeze). In models Beko with the No Frost system, this mode forcibly turns on the compressor at maximum power, ignoring standard shutdown cycles.
Usually users activate this function before loading a large volume of fresh food in order to quickly freeze them, and then forget to turn it off. If the “snowflake” indicator or the corresponding light is on on the panel, the equipment will work in enhanced mode for up to 24–48 hours or until the function is manually turned off.
Check the control panel: if the Super Freeze button is on, press it and hold it for several seconds until the indicator goes off. After this, the unit will return to normal operation.
However, you should be careful: in some electronically controlled models, a failure in the board can simulate the on mode. If the button does not light up, but the refrigerator hums continuously, look deeper for the cause.
Violation of tightness and thermal insulation
If the cold “leaves” freely from the chamber, temperature sensors record the increase in degrees and give the command to the compressor to work without stopping. The main task is to find the place where the tightness of the circuit is broken circuit tightness.
First of all, inspect the sealing rubber on the doors. Over time, it dries out, cracks, or simply becomes overgrown with plaque, causing the door to not fit tightly. Even a gap of 1-2 millimeters can disrupt the entire temperature balance.
Also check whether anything is preventing the door from closing tightly:
- 🥫 Bulging products or dishes resting on a shelf or wall.
- 🧺 Incorrectly installed drawers or trays that interfere with the movement of the door.
- 🧹 Dirt or crumbs on the seal, preventing it from pressing against the body.
- 🏠 Distortion of the refrigerator itself due to an uneven floor.
☑️ Checking the tightness
Perform a simple test: close the door on a sheet of paper. If the sheet can be easily pulled out when the door is closed in different places around the perimeter, then the seal requires replacement or cleaning.
⚠️ Attention: If the seal is severely deformed or torn, attempts to restore it with boiling water or a hairdryer will only give a temporary effect. For Beko it is better to order original rubber, since universal options may not provide the required tightness.
Refrigerant (freon) leak
One of the most common technical reasons why the refrigerator Beko does not turn off is a freon leak. The refrigerant circulates through the system, picking up heat. If its quantity decreases due to microcracks in the tubes or corrosion of the evaporator, the cooling efficiency decreases.
The compressor tries to compensate for the lack of cold by working at the limit, but the temperature in the chamber still does not drop to the set values. As a result, the equipment hums for days on end.
Main signs of a leak:
- ❄️ The freezer is working normally, and the refrigerator compartment is warm.
- 🔥 The side walls of the case (condenser) remain cold or only partially warm.
- 💧 The appearance of oily spots near the compressor or on the floor under the equipment.
- 🔊 Change in the sound of the engine (may become more strained).
Why can’t you just add freon?
Simple refueling without finding and eliminating the leak is temporary solution. The freon will leave again in a few weeks or months, and the compressor may burn out due to operation in an inappropriate mode.
It is difficult to find the location of the leak on your own, since it often occurs in the foamed part of the housing or in hard-to-reach places of the evaporator. The use of a leak detector and professional equipment is required.
Malfunction of the thermostat or temperature sensor
The thermostat (in mechanical models) or temperature sensor (in electronic Beko) is the “brain” that decides when to turn on and when to turn off the engine. If this element fails, it can send the wrong signal that the chamber is too warm, causing the compressor to run continuously.
In mechanical refrigerators, the thermostat is a capillary tube relay. If the tube loses its seal or moves, the contacts do not open. In electronic models, the sensor (thermistor) changes its resistance depending on the temperature. If it breaks down, an erroneous signal is sent to the control board.
Diagnostics requires a multimeter:
- Disconnect the refrigerator from the network.
- Get to the thermostat (usually inside the chamber or behind the back panel).
- Ring the contacts: in a cold state they should be are closed, when heated, they open.
If you are not confident in your abilities, it is better to call a technician, since incorrect installation of a new sensor can lead to the refrigerator not turning on at all.
Problems with the compressor and start relay
The heart of the refrigerator is the compressor. If it hums but does not start, or starts and immediately stalls (clicking), the problem may be with the start relay or the motor windings. However, if the motor is running constantly, but there is not enough cold, this may indicate a loss of compression.
The pistons inside the compressor wear out, and it ceases to create the necessary pressure for freon circulation. In this case, replacing the compressor is not economically feasible on older models, but on modern ones Beko it often makes sense.
Table of symptoms and possible malfunctions of the compressor group:
| Symptom | Possible cause | Solution |
|---|---|---|
| Buzzes, but does not start | Stuck, faulty relay | Replacing the relay or compressor |
| Works without stopping, there is cold | Freon leak, blockage | Searching for leaks, vacuuming |
| The motor housing gets very hot | Overload, wear | Diagnostics of windings |
| Clicks and turns off | Overheat protection | Checking the starting device |
Constant operation of the engine leads to overheating. If you feel that the compressor housing (the black “tank” at the bottom back) is hot to the point where you cannot touch it with your hand, immediately unplug the device.
Clogged capillary tube
Another technical problem typical of the No Frost system and conventional refrigerators is the formation of a blockage in the capillary tube. Through it, freon enters the evaporator under high pressure. If there is moisture or oil breakdown products in the system, an ice or dirt plug will form.
In this case, freon does not circulate, the pressure in the system drops, and the sensors record the absence of cold. The compressor works non-stop, trying to pump the refrigerant, but to no avail.
To eliminate the blockage, you need:
- 🛠️ Removing the filter drier.
- 💨 Blowing the system with nitrogen under pressure.
- 🔄 Installing a new filter and refilling with freon.
Do this yourself the procedure is extremely difficult without specialized equipment (vacuum pump, pressure gauges, burner). Attempts to clean the system using “folk methods” can lead to complete failure of the refrigerator.
⚠️ Attention: Working with refrigerants requires a license and special knowledge. Improper handling of freon is hazardous to health and the environment. If you suspect a blockage or leak, contact a certified service.
Frequently asked questions and answers (FAQ)
How long should a Beko refrigerator work normally?
In normal mode, the refrigerator operates cyclically: it works for about 10-15 minutes and rests for 20-30 minutes. The work rate is about 30-40%. If the compressor hums for more than 20 minutes in a row without a break in a warm room, this is a cause for concern.
Can the refrigerator not turn off in the summer due to the heat?
Yes, in hot weather (+30°C and above) heat exchange is difficult, and the refrigerator may work longer than usual. However, it should still go into standby mode, at least for a short time. If it does not turn off for days, even in summer, then there is a malfunction.
What to do if the refrigerator does not turn off after defrosting?
After complete defrosting (especially if it lasted more than 24 hours), the system takes time (up to 6-8 hours) to enter operating mode and set the temperature. If after a day of operation in an empty state it does not turn off, check the thermostat and the presence of a leak.
Is it dangerous to leave a running refrigerator unattended?
Long-term continuous operation leads to overheating of the wiring and the compressor itself, which creates a risk of fire. If you notice that the equipment does not turn off for more than 24 hours, it is better to disconnect it from the network until the technician arrives.
Is it possible to replace a Beko compressor with an analogue?
Technically, it is possible if the power, type of refrigerant and overall dimensions match. However, for inverter models Beko it is advisable to use original components or certified analogs, since the electronics may not work correctly with a “foreign” motor.
