Situation, when The Beko refrigerator is humming, can unbalance any owner, especially if the equipment is installed in a studio apartment or in a kitchen combined with a living room. Extraneous noise often does not indicate a breakdown, but a violation of operating conditions or improper installation of the unit. In most cases, a hum, vibration or periodic humming does not require calling a technician and can be eliminated independently in 10–15 minutes.
However, sharp metal knocks cannot be ignored, as this may indicate wear on the compressor or problems with the circulation system refrigerant. Modern models loud hum or sharp metallic knocks are not allowed, as this may indicate wear on the compressor or problems with the refrigerant circulation system. Modern models Beko equipped with inverter motors, which are quieter than traditional ones, but they also produce a characteristic low-frequency sound when operating. Understanding the nature of sounds will help you distinguish normal operation of equipment from a serious malfunction.
In this article we will analyze in detail all the possible causes of noise, from simple installation errors to complex technical problems. You will learn how to carry out initial diagnostics, which parts most often fail and when specialist intervention is really necessary. It is important to know: if the hum is accompanied by a lack of cold or icing of the evaporator, operation of the device should be stopped immediately.
Normal operating noise versus malfunction
Before you panic and search service center, it is necessary to determine the nature of the sound. Any refrigerator, including models Beko, cannot operate absolutely silently. The compressor pumping refrigerant through the system always makes a certain hum. This is a physical process of gas compression, which is accompanied by vibration of the motor. In new models with inverter compressors, the sound is smoother and quieter, while classic motors can operate jerkily.
A uniform low-frequency hum is considered normal, which can intensify when the unit is turned on or off. The sounds of flowing liquid (freon) and clicks of the thermostat or start relay are also acceptable. If the refrigerator is humming, but at the same time it maintains a stable temperature, and the sound does not cause physical discomfort at a distance of 1 meter, most likely the equipment is working properly.
The alarm should be sounded if the nature of the sound has changed dramatically. The appearance of a grinding, knocking, whistling or very loud hum that can be heard in the next room are signs of a malfunction. Users often confuse the vibration of the housing with the operation of the motor. To check this, just lightly touch the side wall or door: if you feel a strong vibration under your fingers, the problem probably lies in the resonance of objects or the unstable position of the equipment.
Problems with installation and vibration of the case
The most common reason why The Beko refrigerator is humming loudlyis trivial - incorrect installation. The unit must stand strictly horizontally and not touch walls or furniture. If the legs are not adjusted, the housing will warp, causing the compressor to skew and increase vibration. The vibration is transmitted to the floor, walls and nearby objects, creating the effect of an increasing hum.
Check the distance to the walls. For normal air circulation and absence of resonance, clearances must be maintained. The instruction Beko recommends leaving at least 5–10 cm at the back and sides. If the refrigerator is moved close to a wall or kitchen unit, the vibration of the motor is transmitted to the furniture, causing the entire structure to hum. Also check whether the tubes at the back of the unit are touching each other.
Often the source of noise is objects standing on or inside the refrigerator. Heavy cans, bottles or dishes may resonate with the frequency of the compressor. Even inside the chamber, bottles standing close to the wall can rattle. Remove all excess from the top panel and check the contents of the shelves. If after unloading the noise disappeared, then the reason was in the resonance of objects.
☑️ Installation diagnostics
The influence of location and external factors
The location of the refrigerator in the room plays a critical role in the level of noise emitted. If Beko unit stands on an uneven floor or slippery surface (such as linoleum), it may move or vibrate more than usual. In old houses or on wooden floors, vibration from a running motor can be transmitted to the building structure, creating the feeling that the whole house is humming.
Pay attention to neighboring appliances. Sometimes the hum does not come from the refrigerator itself, but from the hood, microwave oven, or even a washing machine running in spin mode. Sound waves can overlap each other, creating the illusion of increased noise. Try turning off other powerful appliances in the kitchen and listen to the operation refrigeration equipment in silence.
The temperature in the room also affects the operation of the equipment. If the refrigerator is located next to a radiator, oven, or in direct sunlight, the compressor is forced to work almost without interruption to maintain the set temperature. In this mode the motor is humming constantly and louder than usual, since it does not go to rest mode. This is not a breakdown, but this mode of operation significantly reduces the service life of the equipment.
⚠️ Attention: Do not install the refrigerator in a niche without ventilation gaps. Overheating of the compressor due to lack of air leads to constant noise and rapid failure.
Diagnostics of the compressor and cooling system
If external factors are excluded, and refrigerator hums it is still loud, the problem may lie in the “heart” of the unit - the compressor. The models Beko use both classic and inverter compressors. Classic engines make a characteristic click and beep when starting, then run smoothly. If you hear a hum that turns into a howl, or the motor hums but does not start (you can only hear a hum and clicks), these are signs of a faulty start relay or windings.
Induction hum is a common problem with old or worn-out compressors. This is the sound produced by the magnetic field of the motor windings. Over time, the insulation of the windings can weaken, and the core plates begin to vibrate, producing an unpleasant hum. In inverter models Beko this sound is less common, but is possible if the control board is faulty, which supplies incorrect currents to the motor.
It is also worth checking the No Frost system (if your model has it). Fans are responsible for air circulation. If the fan blades are dirty or the bearing is dry, a whistling or hum will appear, which can easily be confused with the noise of a compressor. To localize the source, open the door: in many models, when the door is opened, the fan stops, and if the noise disappears, that’s the problem.
| Sound type | Probable cause | Nature of the malfunction |
|---|---|---|
| Uniform low hum | Compressor operation | Normal |
| Gurgling, overflow | Freon movement | Normal |
| Loud knocking when starting | Wear of engine mount | Requires repair |
| Whistling or howling | Fan or freon leak | Diagnostics needed |
| Humming, but not freezing | Compressor jammed | Urgent repair |
Fan and No Frost system malfunctions
In refrigerators Beko with the No Frost system, fans located in the freezer and refrigerator compartments are responsible for cooling. Over time, ice builds up on the blades or dust gets in, which disrupts the balance. As a result, the fan begins to hum, vibrate, or make a cracking sound. This sound is often described as “wind noise” or a monotonous hum that intensifies when the door is closed.
Another reason for fan noise is drying out of the grease in the bearings. In this case, a characteristic creaking or howling is heard, which may appear and disappear. If the fan is located in the freezer, the sound may be muffled but constant. For diagnostics, you often have to remove the back wall inside the chamber, which requires defrosting the refrigerator for 12–24 hours.
Sometimes the fan touches the ice. This happens if the defrost system is not working correctly and too much ice builds up on the evaporator. The blades begin to touch the ice build-up, making a cracking noise and increasing the roar of the engine. In such cases the refrigerator hums periodically, often after the defrosting cycle or, conversely, before it.
How to check the fan without disassembling?
Plug in the refrigerator, open the door and press the door open sensor (if there is one) or just listen. In many models, the fan stops when the door is open. If the noise disappears, that’s the problem.
When you need to call a technician
There are situations when self-repair not only will not help, but can also be dangerous. If Beko refrigerator it makes loud metallic knocks, grinding noises or a high-pitched whistle, and it stops freezing, most likely the compressor has failed or there is a refrigerant leak. It is prohibited to open a sealed circuit without special equipment and a license.
It is also worth contacting a specialist if you smell burning or scorched plastic. This may indicate overheating of the wiring, melted insulation, or a faulty start relay. Continued use of such a device may result in a short circuit or fire. Inverter compressors Beko are controlled by complex electronics, and diagnosing their malfunctions requires professional tools.
If, after carrying out all preventive measures (leveling, defrosting, checking items) the hum has not decreasedand the temperature inside the chambers no longer corresponds to the set one, you cannot hesitate. Early diagnostics allows you to replace the unit cheaper than repairing the consequences of a complete breakdown of the unit.
⚠️ Attention: Replacing a compressor yourself or soldering pipes requires a license and special equipment. Trying to repair it yourself will void your warranty and can be life-threatening.
Noise prevention and equipment care
In order Beko refrigerator to serve for a long time and work quietly, it is necessary to regularly carry out preventive maintenance. Once every six months it is recommended to check the installation level and, if necessary, tighten the legs, as over time they can become loose. You should also wipe the rear grille from dust, which impedes heat transfer and makes the motor work harder.
It is important to monitor the condition of the rubber seals on the doors. If they do not fit tightly, warm air enters the chamber, the compressor turns on more often and runs longer, which increases the overall noise level. Wipe the seals with a soft, damp cloth and check for cracks. If necessary, lubricate them with special silicone grease.
Do not overload the shelves and make sure that the products do not touch the back wall of the chamber. This will not only improve air circulation, but also reduce the likelihood of resonating sounds. Regular defrosting (for drip systems) or monitoring the operation of the No Frost system will help avoid the build-up of excess ice, which is also a source of noise.
Why does the refrigerator hum after defrosting?
After defrosting, there may be some water left in the system, which makes sounds when freezing or circulating. The compressor may also work harder to build up temperature, which temporarily increases the hum. If the noise does not go away after a day, check whether water has got into the defrost tray or onto the fan.
Is it possible to lubricate the compressor if it is humming?
Self-lubrication of the compressor is impossible, since it is hermetically sealed. The hum may be caused by internal wear on the bearings or windings. Trying to drill a hole for lubrication will result in freon leakage and motor failure. The entire unit needs to be replaced.
Is it normal for a new Beko refrigerator to hum?
New equipment may hum a little louder in the first days of operation, while parts are being ground in and oil is distributed in the compressor. It is also important to let the refrigerator sit for 2-4 hours after delivery before turning it on. If the hum does not subside after a week, check the installation.
How to reduce the noise of a refrigerator in an apartment?
Use anti-vibration stands under the feet, make sure that the unit does not touch the walls, and remove resonating objects. You can also install the refrigerator in a niche with sound-absorbing materials, but not forgetting about ventilation.
