The situation when a refrigerator Beko begins to make unusual sounds always causes concern among owners. A hum, knocking, gurgling or piercing squeak can signal either a minor problem that is easy to fix yourself, or a serious breakdown of the unit components. Understanding the nature of sound is the first step to saving equipment and preserving products.
In this article we will analyze in detail Why is the Beko refrigerator noisyand classify sounds by type. You will learn to distinguish normal operation No Frost from signs of compressor wear. Competent diagnostics will allow you to make the right decision: call a technician or fix the problem yourself.
Natural sounds: when noise is the norm
Modern refrigerators Beko are complex engineering systems in which physical processes are constantly occurring. The transition of the refrigerant from liquid to gaseous state, the operation of automatic defrost systems and air circulation are inevitably accompanied by acoustic effects. Owners are often frightened by sounds that actually indicate normal operation of the unit.
The most common occurrence is gurgling or liquid transfusion. This sound is made by freon moving through the pipes of the cooling system. It can occur immediately after turning on the device or at moments when the compressor changes operating mode. Also acceptable is the quiet crackling of plastic caused by thermal expansion of materials when the temperature inside the chambers changes.
If you hear a periodic hum that either subsides or resumes, most likely it is working compressor. Inverter-controlled models may have a barely audible sound, while classic motors are louder. It is important that this hum be monotonous and not accompanied by vibration of the housing.
It should also be taken into account that the noise level depends on models. Budget series can be louder than their premium counterparts. If the sound does not change over time and does not cause physical discomfort while in the next room, then probably everything is in order with your equipment.
Installation problems and external factors
Before looking for a breakdown inside the mechanism, it is necessary to exclude installation errors. Incorrect installation is the most common reason why Beko refrigerator makes a lot of noise or vibrates. If the body is not level, a resonance occurs, which enhances any operating sounds of the motor.
Check the distance to walls and furniture. The rear condenser grille requires free space for heat dissipation. If the refrigerator is moved close to the wall, the motor begins to work with increased load, which causes an increased hum. Also make sure that the unit does not touch other pieces of furniture or walls.
⚠️ Attention: If the refrigerator makes a loud rattling sound, check that the side walls of the cabinets or pencil cases are not touching it. Vibration from the compressor is transmitted to the housing and causes neighboring objects to rattle.
☑️ Installation diagnostics
Pay special attention to the transportation bolts if the equipment is new. In some models, they may remain attached, causing severe vibration. Make sure that all internal elements - shelves, drawers, bottle holders - are installed in their places and do not rattle when the motor is running.
Malfunctions of the No Frost system and fan
In refrigerators Beko with the system No Frost the fan is responsible for circulating cold air. If you hear an increasing hum that turns into a grinding or knocking noise, the problem most likely lies in this unit. Over time, the fan bearings wear out or get ice in them.
Fan icing is a common cause of noise. This happens when the defrost cycle is disrupted and a “fur coat” grows on the blades. As the fan rotates, it touches the ice, producing a characteristic crackling or buzzing sound. In such cases, defrosting the unit is required for 10–12 hours.
| Sound type | Probable cause | Action |
|---|---|---|
| Whistling or howling | Bearing wear fan | Replacing the fan |
| Crackling of the blades | Ice on the fan | Complete defrosting |
| Humming when opening the door | The fan turns on at maximum speed | Normal or checking the sensor |
If after defrosting the sound returns after a short time, it means the defrost sensor is faulty. The system does not warm up the evaporator, the water does not flow into the drain, but freezes, blocking the operation of the fan. In this case, diagnostics of the electrical circuit will be required. Defrost heating element or defrost sensor. The system does not warm up the evaporator, the water does not flow into the drain, but freezes, blocking the operation of the fan. In this case, diagnostics of the electrical circuit will be required.
How to check the fan without disassembling it?
Open the door of the refrigeration chamber (in some models you need to press the button that simulates closing the door) and listen. If the sound changes or stops when opening, the problem is in the airflow system.
Compressor noise: wear or breakdown?
The compressor is the “heart” of the refrigerator Beko. If it begins to make sounds other than the usual steady hum, this is a serious signal. A knocking, clanging or metallic ringing may indicate internal mechanical damage to the piston group or valves.
One of the common problems is water hammer. It occurs if liquid freon instead of gaseous freon enters the compression chamber of the compressor. This causes a dull thud and can quickly damage the motor. Often the cause is a malfunction of the thermostat, which does not turn off the compressor in time.
It is also worth paying attention to the start relay. If when you try to start you hear a click, then a hum that ends abruptly, and then a click again, the relay cannot start the engine. In some cases, the motor hums, but does not start, which requires immediate disconnection of the device from the network.
Vibration of the compressor can be transmitted to the tubes if they are located too close to each other or to the body. In this case, gently bending the tubes with your hands (with the device turned off!) helps to eliminate contact. However, this must be done extremely carefully so as not to damage the thin metal.
Foreign objects and rattling
Sometimes the source of noise turns out to be trivially simple. Internal shelves, glass inserts or plastic drawers may rattle due to the vibration of a running motor. Check that all removable elements are tightly seated. Bottles with liquid rattle especially often if they touch the walls or each other.
Pay attention to the back wall inside the refrigerator compartment. The evaporator fins are often located there. If food or packaging touches the back wall, the air flow may cause vibration and noise. Make sure there is a gap between the food and the walls.
- 🥤 Check the door shelves: the bottles should not touch each other.
- 🍽️ Make sure the plates on the shelves are stable and do not vibrate.
- ❄️ Check if the drawers are frozen freezers to the walls.
Another source of noise is the drainage system. If the water drainage tube vibrates or touches the body during defrosting, this creates an unpleasant resonating sound. Secure the tube with a clamp or move it away from the metal parts.
When you need to call a technician
There are a number of symptoms in which self-repair is not only useless, but also dangerous. If you hear a burning smell, feel that the motor-compressor is excessively hot, or notice an oil leak under the refrigerator, immediately turn off the device and contact service.
Also, the help of a specialist is needed if after defrosting the noise does not stop, and the temperature in the chambers no longer remains at the required level. This indicates a disruption in the circulation of the refrigerant or failure of the electronic control components.
⚠️ Attention: Self-repair of the cooling system if the seal of the circuit is damaged is prohibited. Freon can be dangerous, and special equipment is required to pump it.
The technician will conduct professional diagnostics, check the pressure in the system, the integrity of the compressor windings and the operation of the electronics. In the case of refrigerators Beko often it is necessary to replace original spare parts, which are difficult to find in regular sales.
Frequently asked questions (FAQ)
Why does the new Beko refrigerator make a loud noise in the first days?
The new unit is going through a break-in period. The compressor works harder to reach the required temperature. You may also hear the sound of freon flowing through the pipes. Usually after 3-5 days the noise level decreases to standard.
The refrigerator makes the sound of a bursting bubble - is this normal?
Yes, this is absolutely normal. The sound resembles bursting bubbles or crackling. It is caused by the expansion and contraction of the plastic parts of the inner box when the temperature changes, as well as the movement of the refrigerant.
What to do if the refrigerator hums only at night?
At night, extraneous noises in the house subside, and the operation of the refrigerator becomes more noticeable. If the hum is monotonous and does not increase, this is normal. If the sound has become louder than before, check the installation of the device and the absence of vibration from neighboring objects.
Is it possible to use a refrigerator if it hums a lot?
If the humming is not accompanied by an increase in temperature in the chambers and a lack of cold, short-term use is possible. However, prolonged noise indicates increased load, which can lead to compressor failure. It is better to carry out diagnostics.
How to reduce the noise of a Beko refrigerator on your own?
Align the refrigerator by tightening the legs. Move it away from the wall at least 10 cm. Check that nothing is touching the body. Make sure nothing is rattling inside. If the noise remains, repairs will be required.
