Temperature of the refrigerator and the
compressor will rise and the compressor will
run for comparatively longer periods when the
refrigerator is first started.
The compressor may produce a slight sound
during operation, or when it is started or
stopped.
A slight sound may be heard when the
appliance is first started due to the operation
of the compressor and motor. The sound will
be lower and lower gradually a short period
later.
Liquid refrigerant flowing in the evaporator
may produce a slight sound similar to that of
flowing water. When the refrigerator is
stopped, the backflow refrigerant may also
generate that sound.
Troubleshooting
When the refrigerator is first operated, the
case may become warm. This is designed to
prevent condensates.
During defrosting process, a slight sound may
be generated. This sound is resulted by
defrosted water dropping to the heater and
by the evaporator.
