Problems
Hiss sounds
Click sounds
Vibration sound
I Explain general principles of sounds.
• All refrigerators make noises when they run.
The compressor and fan produce sounds.
There is a fan in the freezer compartment which blows cool air to freezer and
refrigerator compartments. Hiss sounds are heard when the air passes through
the narrow holes into the freezer and refrigerator compartments.
I Cooling Fan sound in the compressor compartment.
• There is a fan on the back of the refrigerator which cools the compressor
compartment. If there is a small space between the refrigerator and the wall, the
air circulation sounds may be noticeable.
I Noise of Compressor.
• This operating sound happens when the compressor compresses the
refrigerant.
I Explain the principles of temperature change.
• The sounds happens when pipes and the internal evaporator in the refrigerator
compartment expand and contract as the temperature changes during the
refrigerator operation. This sound also happens during defrosting, twice a day,
when the ice on the evaporator melts.
I Check the sound whether it comes from the pipes, vibration, or friction.
• Insert bushing or leave a space between pipes to avoid the noise.
• Fix the fan blade if it is hitting on the shroud
• Fix the drip tray if it is loosened.
I Sound depends on the installation location.
• Sound becomes louder if the refrigerator is installed on a wooden floor or near
a wooden wall. Move it to the another location.
• If the refrigerator is not leveled properly, a small vibration can make a loud
sound. Please adjust the level of the refrigerator.
