The situation when Beko refrigerator begins to make unusual sounds is familiar to many owners of this popular equipment. Humming, ringing, whistling or occasional cracking noises can be annoying, interfere with sleep and cause reasonable concern about the safety of food. Users are often frightened, believing that the unit is out of order, but extraneous noise does not always indicate a serious breakdown.
In this article we will analyze in detail the physics of the processes occurring inside the refrigeration chamber and determine when noise is normal and when intervention from a technician is required. Modern models, such as series NeoFrost or EverFresh, have their own design features that affect the level of acoustic comfort. Understanding the source of the sound is the first step to solving the problem.
It should be immediately noted that diagnosis often requires careful listening and visual inspection. If you notice that The refrigerator is noisy too loud, do not ignore this signal. A timely reaction can prevent costly compressor repairs or refrigerant replacement in the future.
Natural operating noise: when the equipment is working properly
Many owners first encounter a hum immediately after purchase or defrosting. This is due to the fact that compressor in new models it works with a certain frequency. When starting or stopping the engine, the sound level may increase briefly, which is a normal situation. This is especially true for models with inverter motors that smoothly regulate power.
It is also worth considering the refrigerant circulation process. Liquid flowing through the system pipes No Frostmay make gurgling sounds or a slight hiss. This indicates that freon moves freely along the circuit, giving and taking heat. If Beko refrigerator makes such sounds, but at the same time freezes perfectly, there is nothing to worry about.
Thermal expansion of materials is another reason for periodic crackling. The plastic of the inner walls and metal elements contract or expand with a sharp change in temperature. This sound resembles clicking or crackling noises, which usually occurs after opening a door or turning on the fast freezing mode.
⚠️ Attention: If the volume of sounds has increased sharply compared to the first months of operation, this may indicate wear on the shock absorbers or an imbalance.
It is important to distinguish between a monotonous hum and sharp, impactful sounds. The first option is most often associated with the operation of electrical components, the second with mechanical faults. In normal operation refrigerator compartment should be audible only when there is complete silence in the apartment.
Installation problems and vibration of the case
One of the most common reasons why The refrigerator is noisyis incorrect installation. If the unit is not level, vibration from the operating compressor is transmitted to the floor and walls, increasing significantly. This creates a resonance effect where even a quiet motor sounds like a tractor. Vibration is also dangerous for internal tubes, which can burst from constant stress.
Check whether the legs of the refrigerator fit tightly to the floor. It often happens that one of the supports hangs in the air or, conversely, is twisted too much. To make adjustments, use a building level, placing it on the top cover or shelves inside the chamber. The position is adjusted by rotating the front legs.
- 🔹 Check the gap between the back of the refrigerator and the wall: it should be at least 5-7 cm for free air circulation.
- 🔹 Make sure that nothing inside the chamber touches the walls, especially if there are glass jars or bottles there.
- 🔹 Inspect the floor under the refrigerator: the presence of debris or unevenness can cause the cabinet to rattle.
If the refrigerator is moved close to furniture or a wall, this not only worsens the cooling of the condenser, but also increases the noise. Air currents encountering an obstacle create turbulence and whistling. Move the equipment away from the wall at least 10 centimeters.
☑️ Installation diagnostics
In some cases, objects standing on the top lid of the refrigerator become the source of rattling. Microwave ovens, cereal cans, or decorative items may resonate with the frequency of the motor. Remove all foreign objects from the top panel and check whether the acoustic picture has changed.
Faulty compressor and start relay
The heart of the refrigerator - compressor - is the main source of noise. If the motor begins to hum louder than usual, this may indicate wear or overload. In older Beko models with conventional compressors, noise when starting and stopping is normal, but a constant rumble requires attention.
A common problem is the failure of the start relay or motor windings. In this case, the refrigerator may hum, but not start, or make a click and go silent. Start relay responsible for supplying current to the windings, and if it breaks down, the motor cannot return to operating mode, which causes a characteristic hum and overheating.
| Type sound | Probable cause | Necessary actions |
|---|---|---|
| Strong metal clanging | Destruction of the compressor suspension | Replacement of shock absorbers or motor |
| Humming without starting | Malfunction of the starting relay | Replacement of the relay (master required) |
| Smooth but loud hum | Wear of the piston group | Diagnostics of freon pressure |
| Intermittent noise | Problems with the thermostat | Checking temperature sensors |
If you hear how compressor tries to start, emits a short hum and clicks, after which it goes silent for several minutes, this is a clear sign of a malfunction of the start-protection device. You cannot operate the equipment in this mode - the motor may burn out.
⚠️ Attention: Replacing the compressor or start relay yourself requires special skills and tools. Inexperienced intervention can lead to a freon leak.
Compressor life
The average compressor life in Beko refrigerators is 10-15 years. However, with frequent power surges in the network, this period may be reduced. Using a voltage stabilizer prolongs the life of the motor.
Noise of the No Frost system and fan
Beko refrigerators with the system No Frost are equipped with fans that circulate cold air. Over time, fan bearings can wear out, resulting in a whining, whistling, or knocking noise. The sound usually intensifies when you open the door (in some models the fan stops, in others it changes tone).
Another reason for noise in the system No Frost is ice freezing on the fan blades. If the defrost system does not work correctly, ice builds up and begins to interfere with rotation. The fan touches the ice crust, making a cracking or knocking noise. This often happens in the freezer.
To diagnose, you need to listen to where exactly the sound is coming from. If the noise is coming from the top of the refrigerator compartment or from the back of the freezer, the problem is most likely in the fan. In models with two cooling circuits (NeoFrost), there may be two fans, and any of them can make noise.
- ❄️ Check to see if ice has frozen on the evaporator, access to which is often blocked by a plastic panel.
- ❄️ Try gently pressing the door sensor button (if it is mechanical) to stop the fan - if the noise disappears, the problem is there.
- ❄️ Pay attention to the cleanliness of the air duct channels: channels clogged with dust create resistance to airflow.
Replacing a fan is a relatively simple procedure, but requires partial disassembly of the internal lining. It is important to choose an original spare part or a high-quality analogue, since cheap fans are often noisier than the original and quickly fail.
Foreign objects and rattling of parts
Sometimes the reason is trivial: dishes, bottles or shelves rattle inside the refrigerator. When the compressor operates, vibration is created, which is transmitted to all objects. If a glass bottle touches another or a metal grid, a ringing sound occurs. Check the contents of the chambers and eliminate contacts between objects.
It is also worth inspecting the plastic interior parts. Egg trays, vegetable containers, or removable shelves may have cracks or may not fit securely in the grooves. Loose shelf fastenings are a common cause of rattling. Try removing all the shelves and drawers, turning on the refrigerator and listening. If the noise goes away, return the items one at a time to find the culprit.
Pay attention to the back panel on the outside of the refrigerator. There is a condenser grill and a tray for collecting water. If the grille is deformed and touches the body, it will rattle. The water tray may also not be installed tightly.
In models with a display on the door, vibration can cause plastic covers or control buttons to rattle. Secure them if possible, or place a soft material (for example, a piece of foam rubber) in the gaps.
⚠️ Attention: Do not use glue to fix rattling plastic parts inside the chamber - glue fumes can be toxic and spoil the products.
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 Beko refrigerator makes sounds accompanied by a gas leak (a specific odor is felt, although freon is often odorless), calling a specialist is required. You also need to sound the alarm when oil appears under the refrigerator.
If, after eliminating all external causes (vibration, objects, installation), the noise does not stop, and the temperature in the chambers no longer remains at the desired level, the problem is deeper. This may be a violation of the tightness of the circuit, a clogged capillary tube, or a failure of the control electronics.
- 🛠️ The motor hums, but does not start, and a burning smell is heard.
- 🛠️ The refrigerator works without interruptions, and the noise level is constantly increasing.
- 🛠️ Oily spots have appeared on the floor under the compressor.
Professional diagnostics allow you to accurately determine the component that requires replacement. The technician uses pressure gauges to check the pressure in the system and testers to check electrical circuits. Repair of the compressor group requires evacuation of the system and charging with freon, which cannot be done at home without equipment.
Noise prevention and care of equipment
In order Beko refrigerator to serve for a long time and quietly, you need to properly care for it. Regular defrosting (for drip systems) or cleaning the drainage hole prevents the formation of ice plugs, which can cause noise when the defrost system operates. The cleanliness of the condenser at the back is also important - dust impairs heat transfer, causing the motor to work harder and noisier.
Make sure the door seals are tight. If the rubber is worn out or dirty, warm air enters the chamber. The compressor is forced to work longer and more often, which reduces its service life and increases the noise level. Wipe the seals with a soft cloth and check their elasticity.
Do not overload the refrigerator with food. Overcrowded shelves create additional pressure on the structure and can cause objects to shift, leading to noise. In addition, air circulation in a crowded chamber is disrupted, which also affects the operation of the cooling system.
Use anti-vibration pads under the legs of the refrigerator. Special rubber mats or stands dampen vibration transmitted to the floor. This simple and cheap solution often works wonders, making the operation of the equipment almost silent.
Why does the Beko refrigerator hum immediately after turning on?
The humming immediately after turning on is the normal operation of the compressor, which is gaining speed to create the desired pressure in the system. If the humming is steady and after 10-15 minutes goes into quiet mode, there is no need to worry. If the sound is sharp or accompanied by vibration of the case, check the installation.
Is it dangerous if the refrigerator starts to crack?
Rare crackling is the thermal expansion of plastic and metal, which is safe. However, frequent, loud cracking sounds may indicate a fan malfunction (ice is hitting) or destruction of compressor parts. In the latter case, diagnostics are required.
Is it possible to lubricate the compressor if it is noisy?
No, the compressor in household refrigerators is a sealed unit that does not require or allow lubrication during operation. An attempt to drill a hole for lubrication will lead to an instant leak of freon and damage to the unit. A noisy compressor needs to be replaced.
How long should a Beko refrigerator run?
The operating time depends on the load, room temperature and settings. Typically the operating cycle is from 20 to 40 minutes, followed by a pause. If the refrigerator operates around the clock without stopping and is very noisy, check the tightness of the door closure and the temperature in the room.
