The appearance of extraneous sounds in household appliances often becomes an unpleasant surprise that disrupts the usual comfort. If you notice that The Beko refrigerator clicks, you should not ignore this symptom, as it can indicate both harmless physical processes and serious damage to the unit. Modern Beko models are famous for their reliability, but even they are subject to wear and tear or manufacturing defects, which over time begin to reveal themselves with characteristic cracking or clicking noises.
The first thing an owner who is faced with such a problem needs to do is try to localize the source of the sound and understand its frequency. Beko refrigerator can make sounds when turned on, during operation, or immediately after stopping the engine. The nature of the sound also matters: it can be a loud metal clang, a quiet plastic crack, or a sharp electrical click. Understanding the nature of noise will help you make the right decision on further actions.
In this article we will examine in detail the main reasons why extraneous sounds occur in refrigeration equipment of the Turkish brand. We will look at the mechanical, electrical and thermal factors that affect acoustic comfort. It is important to correctly diagnose the problem at an early stage to avoid more expensive repairs in the future.
Natural sounds of materials expansion
The most common and completely safe cause of clicking noises is thermal expansion and contraction of materials. The inner walls of the chamber and the outer panels of the housing are made of plastic or thin metal, which react to temperature changes. When compressor the evaporator turns on and begins to cool, the temperature inside drops sharply, causing the plastic to shrink. This process is accompanied by a characteristic crackling sound, reminiscent of the cooling of a gas stove that has just been turned off.
Such sounds are especially often heard in new models or after defrosting, when the temperature difference between the on and off states is maximum. If the clicking sounds are heard irregularly and are not accompanied by other signs of malfunction, such as lack of cold or vibration, then there is no need to worry. This is normal physical process, characteristic of most refrigeration units.
⚠️ Attention: If the clicks become too loud, frequent and are accompanied by the appearance of cracks on the plastic shelves or walls, this may indicate a defective material or a critical violation of the temperature regime. In this case, you need to check the thermostat settings.
In some cases, the sound may be amplified due to a loose fit of the decorative panels. Over time, the fastening elements may weaken, and the plastic begins to “walk” when the temperature changes, producing louder clicks. Check that all internal elements and shelves are securely fixed.
The effect of humidity on sound
If there is high humidity in the room and a sharp change in temperature, moisture may condense on the surface of the plastic. The entry of microscopic drops into microcracks in the plastic during expansion can create an additional acoustic effect that enhances the crackling sound.
Problems with the compressor and start relay
A more serious cause of clicking sounds is a malfunction in the electrical part of the engine. If you hear a loud click followed by the refrigerator does not start, and then after a while the click repeats, this is a sure sign of problems with the start relay or the compressor itself. The relay tries to start the engine, but due to overload or malfunction of the windings, the circuit breaks, accompanied by a sound.
Frequent clicks without subsequent starting of the motor may indicate that the compressor is jammed. In this case, starting device it will endlessly try to spin it, making rhythmic sounds. This is a dangerous situation, since the engine may burn out from overheating, and excess pressure may develop in the system.
It is also worth paying attention to the condition of the wiring. Loose connections or oxidized terminals can cause micro-discharges that are heard as a quiet crackling sound. If clicks come directly from the black barrel of the compressor at the back of the unit, professional diagnostics are required.
☑️ Compressor diagnostics
Sometimes the problem lies in the start-protection relay itself. This small element is inexpensive, but replacing it requires certain skills. If the relay is “stuck” in the open or closed state, it will make sounds and prevent the refrigerator from working correctly.
Failures in the defrost system
Modern Beko refrigerators are often equipped with a No Frost system, which automatically removes ice from the evaporator. During operation of this system, characteristic clicking noises may also occur. When the heating element of the heater is turned on for defrosting, the ice begins to melt and thaw, which may be accompanied by sounds. However, if the system is not working correctly, the sounds may be louder than usual.
One of the causes of the noise may be a malfunction of the defrost timer or control module. If valve mode switching does not operate smoothly, it may make a sharp knocking noise. It is also worth checking the condition of the heater: if it burns out or works intermittently, this may affect the overall acoustics of the unit.
⚠️ Attention: If clicks in the defrost mode are accompanied by the smell of burning or melted plastic, immediately unplug the refrigerator. This may indicate a short circuit in the heating element circuit.
In models with full automation, the electronic module is responsible for the process. Failures in its software or failure of sensors can lead to chaotic switching on and off of various components, which is audibly perceived as a series of clicks.
Mechanical causes and vibration
The source of sound does not always lie in the electrics. Veko often clicks in the refrigerator due to banal vibration. During operation, the engine creates vibrations that are transmitted to the body and nearby objects. If the refrigerator is not level or touches the cabinet wall, these vibrations turn into knocking and clicking.
Be sure to check the stability of the unit. The legs must be screwed tightly and adjusted to the level. Even a slight misalignment can lead to internal parts touching each other when the compressor operates.
Loose objects inside the chambers can also become a source of sound. Glass shelves, if they are not secured with clamps, can bounce slightly when vibrating and hit the plastic guides, creating a loud clicking sound.
Inspect the back wall of the refrigerator. Sometimes foreign objects may get in there or the protective metal mesh may not be secured there. Vibration from the motor causes loose elements to rattle, simulating a malfunction of internal components.
Faults in the refrigerant circulation system
The refrigerant circulating through the system pipes can also be a source of sounds. In normal mode, this is a gurgling or hissing sound, but if there are problems, the nature of the sound changes. If a plug has formed in the system or the patency of the capillary tube is disrupted, the pressure can jump sharply, causing water hammer, which is heard as clicks.
This is especially common in older models or after poor-quality repairs, when air or moisture could get into the system. Freon when mixed with air it behaves differently, which gives rise to foreign sounds.
The table below will help compare the type of sound with a possible problem in the cooling system:
| Sound type | Probable cause | Danger |
|---|---|---|
| Single loud click | Thermal relay or plastic expansion | Low |
| Series of frequent clicks | Faulty start relay | High |
| Quiet crackling sound during operation | Refrigerant circulation | Medium |
| Metal clanging | Wear of parts compressor | High |
If you suspect a problem with the refrigerant, self-repair is not possible. You need to call a technician with equipment to find leaks and refill the system.
When you need to call a technician
Self-diagnosis is good for identifying simple causes, but there are situations when you cannot do without a specialist. If, after checking the stability and internal shelves, the clicking does not stop, and the refrigerator has stopped freezing or is freezing too much, the problem is deeper.
An alarming signal is the heating of the compressor housing to the point where it is impossible to touch it, combined with constant attempts to start (clicking). This indicates that the motor is operating in emergency mode and may soon fail completely.
⚠️ Attention: Do not try to disassemble the sealed circuit yourself or change the compressor without the appropriate equipment and knowledge. This can lead to final breakdown of the unit and loss of warranty.
The technician will measure the resistance of the windings, check the pressure in the system and diagnose the electronics. Replacing the start relay is one of the most common and inexpensive procedures, which often eliminates the problem of clicking. However, if the motor itself burns out, repairs may not be economically feasible.
Preventing noise and extending service life
If your Beko refrigerator worked quietly and for a long time, it is important to follow the operating rules. Regularly clean the rear grille of dust, as contamination leads to overheating of the compressor and a change in the nature of its operation. Dust acts as a heat insulator, forcing the motor to work at its limit.
Make sure that food does not touch the back wall of the chamber, especially in models without No Frost. Not only does this cause freezing, but it can also transmit vibration, increasing the noise. Correct loading of the cameras is the key to silence.
Check the door seals periodically. If they are dry or dirty, the door may not close tightly, which causes the compressor to work more often and more intensely, increasing the number of on/off cycles and, accordingly, relay clicks.
The influence of voltage in the network
Unstable voltage in the electrical network is a common cause of problems with starting the compressor. If your light flickers frequently, be sure to use a voltage stabilizer to protect the electronics of the refrigerator.
Following these simple recommendations will help minimize the risk of extraneous sounds. Remember that equipment requires attention and care, and then it will delight you with silence and stable operation for many years.
Frequently asked questions (FAQ)
Is it normal that the refrigerator clicks immediately after being plugged in?
Yes, this is normal. When switched on, the start relay is activated to start the compressor, which is accompanied by a characteristic clicking sound. If after this the refrigerator starts working and freezing, there is no cause for concern.
Why does the refrigerator click but does not freeze?
Most likely, the start-up relay or the compressor itself has failed. The relay clicks, trying to start the engine, but due to a malfunction, starting does not occur and no cold is produced. Diagnostics by a specialist is required.
Can ice click in the freezer?
Yes, with the No Frost system or with manual defrosting, pieces of ice can crack and fall onto the shelf or evaporator, making sounds similar to clicks. Ice can also crack when the temperature changes.
How to distinguish a relay click from a plastic click?
The relay click is usually louder, more metallic, and is heard from the bottom where the motor is located. The clicks of plastic are dull, crackling and audible inside the chambers or from the walls of the case.
