A refrigerator that is running makes noises all the time. Sometimes they sound hissing or gurgling. Often from its bowels, you can hear a quiet rumbling or humming. But how to understand which of them indicate normal operation of the device and which do not? Let’s understand everything in order.


This manual is suitable for all manufacturers of home appliances, whether Samsung, Electrolux, Bosch, Lg, or Siemens.


Normal refrigerator sounds

To begin with, any working refrigerator will make different sounds from time to time. This is due to the principle of operation.


If there are no breakdowns, the appliances will make different sounds:


– A quiet hum when the compressor is running. It can be compared to the sounds that the compressor makes in the aquarium.

– A gurgling, gurgling, or hissing sound. These sounds tell about the movement of freon inside the tube systems.

– In old Soviet units, you can hear a brief clang, after a brief hum from the compressor. There is no need to fear – it is the noise of the motor stops.


But not all noises are considered normal. Some noises are due to a malfunction in the main components of the refrigerator.


Varieties of noises

Sometimes you may hear suspicious loud noises from your refrigerator that you haven’t heard before. These noises can come from different units. The main thing is to understand that this noise appeared as a consequence of a breakdown, rather than the stable operation of the appliances.


It is also worth considering the fact that each particular model may have its own specific noises that cannot be found in other devices. This is due to the design features of different devices and their functionality.


It is necessary to understand that in serviceable equipment you can hear a quiet hum from the compressor. In this case, we are talking about a strong noise, which can be identified as a powerful hum.


Because of tightened shipping bolts. They hold the compressor in place during shipping. If they are not removed, the motor will begin to make a strong hum when starting.


Due to improper installation. The refrigerator begins to “growl”, both on high notes and low notes if it is bent to one side. In this position, the compressor is skewed and begins to hum.


In some cases, the hum can be caused by a clogged refrigerant tube or an overdose of freon, after repairs have been made. The compressor cannot run the refrigerant through the system in its entirety, resulting in an increased load on the motor. A hum occurs.


In general, buzzing at the first start is normal. The compressor works at full speed to disperse freon and create working pressure throughout the system. Because of this you hear an increased hum, some people think it resembles a “mooing”.



Basically gurgling testifies to the correct work of the refrigerator. But if thus the compressor is silent, most likely in the device there is a breakdown in a tube with freon. Therefore it is heard as air with the rest of the refrigerant gurgles, sometimes the process is accompanied by not loud popping and crackling.



Gritting and creaking are characteristic of models with the “No Frost” function. In this case, there is a failure in the defrosting system. Frost forms inside the device. The built-in fan clings to the ice edges with its blades and a characteristic rattle occurs.


Rattling and ringing

Most often, the cause of strange sounds is badly tightened bolts fixing the parts inside the refrigerator case. The rattling, ringing, crackling, crunching, and roaring can be both the compressor and various plastic parts. For the elimination of noises, it is possible to try to establish the technics on a level. The cause of rattling can be hidden in the misalignment of the device or its location against other furniture.



When stopping the motor on loose mounts and shock absorbers, you may hear a single or series of knocks. It is caused by the motor repeatedly hitting the walls of the refrigerator.


If you still did not manage to recognize the cause of this breakdown by all the points provided above, or if you do not want to waste time guessing, North Country Appliance Repair Service is always happy to help you and provide a professional diagnosis and repair of your refrigerator in a timely manner.
