5 reasons why the signal turns on, not related to a breakdown
The occurrence of an alarm signal when the device door is visually closed, not accompanied by other changes in its functioning, may indicate the presence of minor malfunctions that can be eliminated very simply.
If a Bosch, , Liebherr refrigerator or an appliance of another brand beeps, before calling a technician, pay attention to the following points:
- How long ago did you connect the device to the network? When you turn on the device for the first time after purchase, the squeak will continue until the temperature inside the refrigerator reaches the programmed value.
- Is its door tightly closed? Even if there is a minimal gap, the device will indicate a malfunction with an audible signal. Holding the refrigerator open for a long time will also turn on the sound, for example, Atlas will start beeping after 30 seconds from the moment the door is opened. Models of some devices, for example the Bosch brand, are equipped with a function for locking the door after it has been left open for a long time. The owner will not be able to open the refrigerator until it reaches the required temperature.
- Did you place too many products at one time? If you place a large amount of unrefrigerated food into the refrigerator at once, the temperature inside the appliance will increase. It will take 5 to 15 minutes to resume the set temperature, during which the device will emit a loud signal.
- Is there a large layer of ice in the freezer? When a thick layer of ice freezes, the temperature sensor inside the chamber incorrectly reads it. This situation can occur in refrigerators of various brands, including models with the No Frost system. To fix the problem, you need to defrost the refrigerator by turning it off for a period of time - from 10 hours to 24 hours. If the device continues to beep, the problem is due to something else.
- Is the Quick Freeze function enabled? In some refrigerator models, activation of this option is accompanied by a signal turning on. After turning off the intensive freeze mode, the sound should stop.
If, after eliminating the above points, the sound signal continues to occur, this indicates the presence of a serious system failure that requires prompt elimination. In this case, you will not be able to cope without professional help.
Before the specialists arrive, the annoying sound can be turned off. This can be done using the corresponding button on the control panel. In devices from different manufacturers, it may be called and look differently:
- in devices of the Samsung and Liebherr brands - a button called Alarm;
- in Bosch refrigerators - image of the speaker;
- in Nord cooling units - the sign of a crossed out bell.
Remember! Manually muting the sound is a temporary solution to the situation. It is necessary to eliminate the cause of its occurrence as soon as possible in order to avoid causing even more damage to the refrigerator.
Possible breakdowns
If you hear your Bosch refrigerator beeping, carefully inspect it for defects or signs of damage. Often the problem can be fixed with your own hands without the involvement of specialists. Therefore, before calling a professional technician to your home, follow these steps:
- Check that the door to the refrigerator compartment is tightly closed. According to statistics, in most cases, a Bosch, Liebherr, Electrolux or LG refrigerator squeaks due to the doors not closing tightly. Some models begin to make a sound after 30 seconds of being open. They may also have an opening lock function, so if the door is left open for a long time, the refrigerator will automatically lock it after closing to restore operating temperature.
- Make sure that there are no objects inside the device that would interfere with the door's tight fit to the cabinet.
- If the handle is in contact with the door, rearrange the dishes and turn them in the opposite direction.
If your Bosch refrigerator beeps when the door is closed, but there is no apparent reason for this, consider the following situations:
- It is possible that the chamber contains a large number of products, warmed to room temperature, that were loaded at the same time. As a result, the internal space has temporarily heated up, which is accompanied by a characteristic squeak from the system. In this case, there is no reason to worry. Just wait a few minutes and the annoying signal will disappear.
- If the refrigerator is new, then the sound may be due to the set operating temperature. It will take about 1 day to optimize the temperature regime, so during the first day the device may beep.

In addition, you need to evaluate the following points:
- How long ago the device was connected to the power supply. The first connection to the network results in a squeaking sound, which is repeated until the temperature level stabilizes.
- Is there a thick coating of ice in the freezer? If the internal surfaces begin to freeze, the sensor will no longer read the temperature normally. A similar problem occurs in many refrigerators, including devices with No Frost technology. To fix the problem, just run a defrost cycle and then turn off the equipment for 10-24 hours. If the problem does not go away and the refrigerator continues to beep after defrosting, the cause of the breakdown must be looked for elsewhere.
- Is the quick freeze option activated? In some outlets of refrigeration chambers, starting the system causes a characteristic squeak. If you turn off the intensive freeze mode, the signal will disappear.
Leakage of working fluid
When operating refrigeration equipment, a leakage of the working substance - the refrigerant, which circulates in the tubes on the rear wall of the housing - often occurs. The problem occurs for various reasons, including a puncture of the evaporator, defects in the pipe, or the development of corrosion processes. In addition to the occurrence of an emergency alert, the problem leads to the following consequences:
- Continuous operation of the device with frequent starting of the compressor.
- Insufficient cooling in the chambers.
- Launching a light indicator notifying about emergency situations.
- Displaying error information on the refrigerator display, if provided by the model.
To eliminate errors, you should determine where the leak occurred, seal it with a sealing compound and restore the refrigerant supply.
Temperature sensor is broken
If your Liebherr refrigerator (or any other brand model) beeps, make sure the thermistor is working.
If this unit breaks down, a temperature jump occurs inside the chamber, affecting both one cooling compartment and the freezer compartment.
In addition to the emergency notification, the refrigerator will no longer remain cold, and the light indication will begin to flash continuously. If there is a built-in screen, in the event of a sensor failure, a characteristic error code will be displayed.

The compressor will continue to function without interruption, adjusting the temperature regime. The problem of temperature sensor failure occurs on different models of refrigeration equipment. To eliminate a defect on the refrigerator Atlant, LG and other models, it is enough to replace the part.
Failures in the circulation system
Sudden activation of the alarm on the refrigerator LG, Electrolux, Samsung, Biryusa, etc.
also occurs when there is a problem in the circulation system. In rare cases, the problem occurs due to natural wear and tear of the compressor due to prolonged and diligent use. This is accompanied by a decrease in the performance of the supercharger, due to which the refrigerator compartment ceases to normally remove thermal energy from the compartments. Abnormal operation of the compressor is accompanied by frequent switching on and off of equipment, as well as continuous operation of the engine. In addition, the compressor may fail to start due to faulty auxiliary parts or the motor.
If you have determined why the system is beeping, perform a visual inspection of the compressor in order to localize traces of mechanical breakdowns and defects. Then seek professional help to replace the unit. If the refrigerator is under warranty, the part will be replaced free of charge.
Violation of tightness
A common cause of annoying squeaking sounds from the refrigerator is a loss of seal. It occurs against the background of wear of the rubber seals, which are located around the perimeter of the doors. When closed, they isolate the chamber from outside air.
With prolonged use, the rubber bands become contaminated with grease from the fingers and other debris. In addition, they can dry out and change properties, becoming deformed and rough. All this provokes the doors not closing tightly. To eliminate the problem, it is enough to regularly clean the seals and rinse them with warm liquid to maintain the sealing properties of the material.
To assess the tightness of the seal, you can use simple paper, which is applied to the body along the perimeter of the sealing rubber. If there are no problems, the sheet will be difficult to pull out of the door.
11 faults requiring repair action
The occurrence of a sound signal that cannot be eliminated on your own is often accompanied by additional attributes: a flashing light, an increase in temperature. We list the most likely malfunctions that may be accompanied by such symptoms.
Freon leak
Refrigerant leakage from the system can occur due to the development of corrosion processes, a puncture of the evaporator or damage to the pipe. In addition to turning on the alarm signal, a breakdown often manifests itself in the occurrence of the following phenomena:
- continuous operation or excessively frequent activation of the compressor;
- lack of cooling in one or both refrigerator chambers;
- turning on the emergency mode indicator light;
- displaying error information on the device display, in particular in models of the Ariston, Siemens, Haier brands.
To fix the breakdown, you need to find the damage through which the refrigerant is leaking, seal it and refill the system with freon.
Temperature sensor malfunction
The alarm sound is activated due to a breakdown of the thermistor, which leads to an increase in the temperature inside the refrigerator. The malfunction may affect either one cooling compartment or the freezer.
In parallel with the sound signal, you can detect a lack of cold in the compartments of the device, a flashing indicator light and an error code displayed on the electronic model display. The compressor works without interruption, trying to restore the required temperature.
The problem of a malfunctioning temperature sensor is often found in refrigerators of the Electrolux and Siemens brands.
Troubleshooting involves replacing the broken temperature sensor.
Motor failure
If your refrigerator has been in use for a long time, a high-pitched squeaking sound when the door is closed may be caused by a compressor malfunction. Such a breakdown is often observed in Minsk refrigerators.
The problem can manifest itself in several ways.

Electronic unit malfunction
Failure of the electronics unit can occur for several reasons:
- due to frequent voltage surges;
- due to oxidation of the board contacts - as a result of high humidity in the room where the refrigerator is located;
- through the fault of the manufacturer - due to a manufacturing defect.
A beep is not the only sign of a board failure. In addition to it, you can diagnose the cessation of cold supply to one or both compartments of the household appliance. In some models of refrigerators from brands such as Electrolux and Samsung, the color indicator blinks. Units from Minsk and Virpul companies will notify owners of the problem by constantly beeping.
To bring the refrigerator into working order, you need to reflash the board or replace it with a new one.
Door seal wear
The occurrence of an insistent squeak may be due to the fact that the refrigerator door does not close tightly due to abrasion of the seal. Damage to the material can also be caused by the way the equipment is used: opening and closing the door too often, or slamming it.
The consequence of peeling and deformation of the seal is a violation of the temperature regime inside the unit, which it tries to convey with the help of sound and light alarms.
You can fix the violation yourself. To do this, follow these steps:
- determine the location of the loose fit by placing strips of paper between the door and the refrigerator body;
- after identifying the area where the rubber band has moved away from the door, carefully glue it with suitable glue;
- if the area of damage to the seal is too large, remove the deformed rubber band and replace it with a new one.
Fan failure
A malfunction of the cooler that supplies air to the refrigerator chambers may look different depending on the type of household appliance:
- In a refrigerator with the No Frost system, the temperature inside the freezer chamber of the device rises, while the compressor works properly. The sound signal sounds continuously, the emergency LED may blink.
- In devices with the Full No Frost system, if the fan breaks down, the air temperature will increase both in the refrigerator compartment and in the freezer.
- In a unit with a drip defrosting system, the malfunction will be indicated by an audible signal. The device's cameras will operate normally.
To restore normal operation of the refrigerator if the cooler breaks down, it must be replaced with a new one.
Damper jamming
One of the reasons for the constant squeaking sound of a refrigerator with a Full No Frost system is the jamming of the damper in the “No supply” mode. This means that cold air from the evaporator does not enter the appliance compartment.
There may be several reasons for this phenomenon: failure of the reed switch or gear motor, icing of the damper.
The way to solve the problem is to replace the broken parts with new ones.
Defrost system malfunction
Malfunctions in the functioning of the elements of the defrosting system most often worry owners of refrigerators equipped with the No Frost system. Freezing of the air ducts leads to the fact that cold air stops flowing into the main chamber of the device. As a result, the temperature rises and the refrigerator begins to emit a warning beep.
In addition to the sound signal, a breakdown is indicated by the freezing of a thick layer of ice on the evaporator and the flashing of the red indicator.
To restore the normal functioning of the cooling device, you will need to replace the faulty defrosting system component.
Broken door sensor
Specialists are often contacted with the following complaints:
- the refrigerator beeps without stopping when the door is closed;
- the color indicator lights up or flashes on the display;
- The device freezes normally and maintains the programmed temperature.
After diagnostics, it most often turns out that the cause of the problems is the incorrect functioning of the door closing sensor. When the door is completely closed, the refrigerator assumes the presence of a gap, and therefore signals a malfunction.
The method to solve the problem is to replace the broken reed switch with a new one.
User control panel malfunction
Owners of refrigerators of various brands are often concerned about why, when the door is closed, the appliance begins to emit periodic or incessant squeaking, and why the indicator lights on the display light up or blink randomly. Despite the fact that both compartments of the two-chamber refrigerator work properly.
Most often, the reason is that one or more buttons on the control panel are broken.
To fix the problem, you need to replace individual broken buttons or the entire panel.
Electronic display defect
The squeaking of sound sensors in some cases may be accompanied by the absence of any digital display indication. Often the problem is accompanied by the cessation of lighting of the device’s cameras.
Most often, the reason is damage to the cable that connects the control module to the door. The defect can be eliminated quite simply - by replacing the cable with a new one.
Prevention of breakdowns
Refrigerator repair specialists note that the following points contribute to appliance failure:
- Long-term operation without maintenance. Even if the unit operates without problems, maintenance should be carried out from time to time. This will help to timely identify minor deviations in operation and prevent serious breakdowns.
- Frequent voltage fluctuations. Due to regular power surges, the electronic control unit may burn out and the compressor motor may fail. Most often, such problems bother owners of Candy and Biryusa refrigerators, which are designed for stable voltage. To prevent this situation, experts recommend using a voltage control relay.
- Excessive physical impact. If you regularly open and close the refrigerator door with great force, over time the seal will become thinner and may peel off in some places. Control panel buttons may also become unusable if exposed to excessive pressure. Therefore, in order to avoid damage, it is necessary to use the device carefully, avoiding unreasonably strong impact on its component parts.
Let's sum it up
A persistent squeak from the refrigerator when the door is closed may indicate a number of problems of varying degrees of complexity. If squealing is the only factor that bothers you, check whether the door is tightly closed, whether it is time to defrost the appliance, or whether it is operating in intensive freezing mode.
In cases where the device not only beeps, but also whistles, hums and flashes light indicators, it requires careful diagnostics. This applies to units of any brands: Candy, Samsung, Haier, Electrolux, Galaxy. When the temperature inside the refrigerator chambers rises, the problem may be a freon leak, a breakdown of the compressor, fan or defrosting system. There may be a situation where, with incessant squeaking and blinking indicators, the unit freezes properly. This is due to the fact that the fault is in the control panel or the door closing sensor.
If you cannot find and eliminate the cause of the squeak on your own, it is advisable to immediately contact specialists in the maintenance and repair of refrigeration equipment. Often, the catalog of services provided by large service centers includes performing all of the listed types of work to eliminate the malfunction that caused the sound signal to turn on.

Other reasons
If the refrigerator beeps when the door is closed, the reason may lie in minor faults. You should find out about them in order to conduct an initial diagnosis and try to solve the problem yourself.
Broken door sensor
If the Liebherr refrigerator beeps, there is a possibility that the door closing sensor has failed. It is impossible to fix the problem yourself without knowledge in this area. You should call a professional to carry out repairs. Until this time, it is recommended to turn off the equipment.
Refrigerant leak
Squeaking noise in Electrolux, Bosch, and Samsung models may be caused by a refrigerant leak. Most likely, there is a crack somewhere through which freon has leaked. In this case, the unit will not only make sound, but will also not produce cold. You need to check the cameras; if there is no frost, you will need to call a technician.
The specialist will conduct diagnostics, determine the location of the leak, perform sealing and refill the equipment with freon. Before he arrives, you need to turn off the unit, remove food and ice.
Temperature sensor failure
Failure of the temperature sensor causes the refrigerator to emit an alarm. At the same time, cold is no longer produced in the chambers, but the engine still works properly.
Some models display error code F2, and in some units the alarm light blinks. The only way to solve the problem is to replace the temperature sensor. For this purpose, you should invite a master.
Seal wear
If your Bosch refrigerator beeps, you need to inspect the rubber layer for defects and tight fit to the body. It often wears out, and warm air enters the chamber unnoticed by humans.
If the seal has kinks, cracks, or holes, it needs to be replaced. The process is simple and does not require special knowledge. If you call a specialist, the repair will cost up to 1,500 rubles.
Most often, the refrigerator beeps due to a poorly closed door. You need to cover it tightly, push in containers and rearrange food for the beep to stop. If the squeak does not disappear, you should invite a specialist to diagnose and repair the equipment.
