to eliminate this sound adjust the leveling down to the floor giving the unit a backwards slope. Note: if the leveling legs are not adjusted down, this sound may occur. The above factors are all parts of proper installation.

If any of the above is affecting the unit, it will cause the refrigerator to make noise during operation. The floor where the refrigerator is installed should be as level as possible. The refrigerator cabinet should be leveled. Popping or tapping sounds may also occur if the unit is moved while it is in operation.įor these types of noise problems, the following items should be in order: Popping or tapping sounds can occur for 30 - 90 seconds when the compressor begins to run, this is common to models that are equipped with a linear compressor. Please visit our Request a Repair page for a professional service. But if the noise becomes louder or can be heard from another room, the unit will require a repair service.

The standard compressor will make a low buzzing or humming noise during normal operation.

If this sort of unexpected noise continues for more than one hour at a time, the unit will require a repair service. If the compressor goes into a higher speed than normal, it can make noises that resemble buzzing, knocking, or banging. This change in speed will produce more activity on the compressor, which in turn results to an increased sound. The linear compressor will change speeds according to the needs of the refrigerator in order to cool both the refrigerator and freezer compartments effectively. Units with linear compressors can often be recognized easily by the insignia located on the control panel. There are two types of compressors, the linear compressor and standard compressor. The compressor noise is supposed to be normal operation, and it is not supposed to last more than 1 hour, but if the noise is loud enough to be heard from another room, then the unit requires a repair service.īefore we conclude that the noise occurs all the time and the unit requires a repair service, let's get a closer look at the compressor. The humming and buzzing noise is coming from the compressor.
