The situation when the refrigerator Beko buzzes without interruption, and the compressor does not stop for a minute, is familiar to many owners of this popular Turkish equipment. In normal operation, the unit should turn on and off cyclically, maintaining the specified temperature conditions inside the chambers. If the motor works non-stop, this not only leads to huge bills for electricity, but also creates a direct threat to the safety of the device itself due to overheating of the components.
There can be many reasons for this behavior: from a banal blockage of the drainage system to a serious refrigerant leak or failure of the electronics. It is important to understandthat ignoring the first symptoms of constant operation of the compressor can lead to its complete combustion, the repair of which is often comparable to the cost of a new refrigerator. Let's look at the main factors influencing this process.
The first thing to do is to assess the scale of the problem. If the equipment has just been defrosted or a large amount of warm food has been loaded into it, prolonged operation is quite natural. However, if the “no rest” mode lasts more than 12–24 hours, it is necessary to sound the alarm. Modern inverter compressors they can indeed work longer than usual, but they should change speed and not constantly hum at the power limit.
The influence of external factors and operating conditions
Before looking for breakdowns within the system, it is worth eliminating operational errors. Often users themselves create conditions under which Veko refrigerator they are forced to work more intensely. For example, installing the unit close to a wall or in a niche without gaps for ventilation leads to overheating of the condenser. In this case, the heat is not removed effectively, and the sensors detect insufficient cooling, causing the motor to work without stopping.
Another common factor is the room temperature. If the refrigerator is located next to the stove, radiator, or in direct sunlight, the system does not have time to release heat. It is also worth checking the tightness of the door. If sealing rubber is worn out or dirty, warm air constantly flows inside, forcing the automation to keep the compressor on.
⚠️ Attention: Do not install the refrigerator in niches where the distance to the walls is less than 5-7 cm. Impaired heat transfer is one of the main reasons for premature failure of the compressor due to oil overheating.
Check the temperature settings. If you accidentally set the maximum cooling (Super Freeze mode or minimum degrees), the equipment will tend to reach unrealistically low values. In summer, this may be physically impossible, and the engine will run idle. Try returning the settings to standard values: +4..+5°C for the refrigerator and -18°C for the freezer.
Loading frequency also plays a role. If you just put a bucket of hot soup or defrosted meat at room temperature into the chamber, the refrigerator will run until the food has cooled down. In such cases cooling cycle may last a day or more, which is a normal situation and not a breakdown.
Malfunctions of the control system and sensors
If external factors are excluded, the problem most likely lies in the “brains” or “sense organs” of the refrigerator. The electronic control module receives data from various sensors and makes a decision to turn the compressor on or off. If this data is distorted, the operation algorithm is disrupted. Most often, the culprit is thermostat (in mechanical models) or a temperature sensor (in electronic ones).
In models with mechanical control, the thermostat is a device with a capillary tube that responds to changes in temperature. If the tube is leaking or dislodged, the contacts may become stuck in the on position. In electronic models, thermistors are responsible for this. Their resistance changes depending on the temperature, and if the sensor “lies”, the controller does not see that the norm has already been reached.
Another important element is the defrost sensor. In systems No Frost it controls the process of defrosting the evaporator. If it is faulty, the refrigerator may not go into defrost mode or, conversely, not start cooling after it, although more often this leads to freezing rather than constant operation. However, a failure in the control circuit can block the signal to stop the compressor.
Diagnostics of these elements requires a multimeter. It is necessary to “ring” the sensors to ensure that their nominal resistance corresponds to the current temperature. If the values deviate significantly from the tabulated ones, the part must be replaced.
Problems with refrigerant and compressor
The most serious and expensive group of reasons is associated with a violation of the tightness of the circuit or wear and tear of the very heart of the refrigerator - the compressor. If the system freon leakpressure drops, the refrigerant cannot absorb heat effectively. The compressor runs constantly, trying to compensate for the lack of gas, but the temperature does not drop to the set values. In this case, you may notice that the back wall of the refrigerator either does not get colder at all, or is covered with an uneven “fur coat.”
Wear of the compressor also leads to loss of performance. The piston group may wear out, the valves may burn out or become coked with soot. In this state, the motor hums and vibrates, but does not create the necessary pressure. It runs “idle”, consuming electricity but not cooling the camera. This can be determined by the characteristic sound: instead of a smooth hum, a metallic knock or ringing is heard.
Clogged capillary tube is another reason for changes in pressure in the system. If the filter drier is clogged with oil or moisture breakdown products, the circulation of freon is disrupted. The pressure at the outlet of the compressor increases, and at the inlet it decreases. The unit is trying to push through the plug, working without interruption, but there is no cold. Often in such cases, you can hear gurgling or see that the condenser (grid at the back) is only partially hot.
| Symptom | Probable cause | Difficulty of repair |
|---|---|---|
| Compressor is hot, no cold | Freon leakage | High (needs a technician) |
| Strong vibration and knocking | Compressor wear | High (replacement of unit) |
| The refrigerator turns on for 1 minute, turns off for 10 minutes | Malfunction of the start relay | Medium (you can do it yourself) |
| Works constantly, but freezes weakly | Clogged capillary tubes | High (requires a master) |
Failures in the defrost system (for No Frost models)
In refrigerators Beko No Frost constant operation of the compressor is often associated with problems with the defrost system. If the evaporator is covered with ice, air cannot circulate through the chambers. The temperature sensor in the refrigerator compartment does not detect cooling and gives the command to continue working. In this case, there may be cold in the freezer, and warmth in the upper chamber.
Key elements that need to be checked: defrost heating element, timer (or electronic defrost control module) and defrost sensor. If the heating element burns out, the ice does not melt, and the “fur coat” grows, blocking the channels. If the timer is faulty, it simply does not switch the refrigerator to defrost mode. This can be checked visually by disassembling the back panel in the freezer.
Often the problem lies in the drainage hole. If it is clogged with dirt or ice, the water does not melt away, but freezes below, forming an ice plug. This also disrupts the entire system. Cleaning the drainage with a soft wire or warm water often solves the problem without calling a technician.
⚠️ Attention: If you find a thick layer of ice on the evaporator, do not try to chip it off with a knife or sharp objects. Damage to the evaporator tubes will lead to an immediate leak of freon and expensive repairs.
How to check the defrost heating element with a multimeter?
To check the heating element, you need to remove the back panel of the freezer, find the heating element (usually a curved tube at the bottom) and test it with the probes of a multimeter. The resistance of a working heating element is usually from 200 to 400 Ohms. If the device shows a break (one on the left) or zero, the heating element has burned out and requires replacement.
Diagnostics and troubleshooting with your own hands
To understand what exactly is wrong, you can carry out an initial diagnosis. Start with a visual inspection: check if the door closes tightly, if there is ice on the back wall, if the light inside is on when the door is closed (if the light is on, it heats the chamber). Then listen to the operation of the motor: is the sound smooth, are there any clicks.
Check the temperature of the condenser (grids at the back or on the sides). Normally, it should be hot evenly over the entire area. If only a part is hot (for example, near the compressor), and the rest of the tube is cold, this is a sign of a leak or blockage. If the grill is barely warm or cold when the engine is running, there is most likely a problem with the compressor or a leak.
Use a multimeter to check the continuity of the circuits. Ring the thermostat: at room temperature it should “ring” (be closed), when cooled it should open. Check the compressor start relay: it should not have a burning smell, and the contacts inside should be clean. These simple steps will help narrow down your search.
☑️ Primary diagnostics of the refrigerator
When you need to call a technician
There are a number of situations when self-repair is not only useless, but also dangerous. If the diagnostics showed a freon leak, special equipment is required to find the location of the damage, evacuate the system and charge it with refrigerant. On your own It is impossible to carry out this work efficiently without professional tools.
Replacing the compressor also requires skills in soldering copper pipes and working with refrigerants. In addition, modern compressors often require precise selection of oil and type of freon. An error in the selection of components can lead to rapid failure of the new unit.
If the problem lies in the electronic control module, it will need to be repaired or reflashed. Attempting to solder a board without a diagram and experience may result in a short circuit and fire. In such cases, it is better to trust the specialists of the service center Beko.
Prevention and proper care
To extend the life of the refrigerator and avoid situations with constant operation, it is important to follow the operating rules. Defrost the unit regularly (even the No Frost system is recommended to be defrosted once a year for prevention). Keep the condenser clean: dust and animal hair, settling on the grille at the back, act as a heat insulator, interfering with cooling.
Check the condition of the seals. Wipe them with a soft cloth and soapy water to remove any grease or stickiness. If the rubber band becomes stiff or cracked, replace it. Also, do not place hot foods in the chamber and try not to open the door longer than necessary.
Regularly checking the temperature will help you notice deviations in time. If you see that the refrigerator has started working longer than usual, do not wait for a complete breakdown - carry out diagnostics. Early detection of a problem often allows you to solve it with little effort, for example, by replacing a cheap sensor, avoiding replacing the compressor.
FAQ: Frequently asked questions
Can a Veko refrigerator work without interruption in hot weather?
Yes, in very hot weather (above +30°C indoors) the refrigerator can work almost non-stop, as it is difficult for it release heat. However, it should still at least briefly reduce the speed or turn off. If it works at maximum for more than 24 hours even in the heat, this is a sign of a malfunction.
Why does the new Beko refrigerator not turn off for a long time after the first turn on?
When first started or after a long defrosting, the refrigerator takes time (from 4 to 12 hours) to cool the entire volume of chambers and food to the set temperature. During this period, working non-stop is the norm. Do not load the chamber with products before entering the mode.
Is it dangerous if the compressor is very hot?
The compressor should normally be hot (up to 70-90°C), as it compresses the gas. However, if it is heated to such an extent that it hurts to touch it, or there is a burning smell, it is dangerous. You must immediately disconnect the device from the network and call a technician.
How to reset a Beko refrigerator?
To reset electronics errors, a full reboot often helps: unplug the refrigerator for 10-15 minutes, then turn it on again. In some models with a display, you can reset through the settings menu by holding down certain combinations of buttons (for instructions, see the manual for the specific model).
How much does it cost to repair if the refrigerator does not turn off?
The cost depends on the breakdown. Replacing the sensor or thermostat will cost the least. Freon refilling and leak detection are more expensive. Replacing a compressor is the most expensive procedure. The exact price can be found out only after diagnostics by a specialist.
