NORMAL OPERATING SOUNDS
Understanding the sounds
coming from the refrigerator
High-eciency refrigerators may
introduce unfamiliar sounds. These
sounds normally indicate the refrigerator
is operating correctly. Some surfaces on
floors, walls, and kitchen cabinets may
make these sounds more noticeable.
The following is a list of major
components in the refrigerator and the
sounds they can cause:
A Evaporator Refrigerant through
the evaporator may create a
boiling or gurgling sound.
B Evaporator fan You may hear
sounds of air being forced
through the refrigerator by
the evaporator.
C Defrost heaters During defrost
cycles, water dripping onto the
defrost heaters may cause a
hissing or sizzling sound. After
defrosting, a popping sound
may occur.
D Automatic ice maker When
ice has been produced, you may
hear sounds of ice cubes falling
into the ice bin. The ice maker
fan, water valve activation, and
refrigerant gas fluid may create
sounds from its operation.
E Electronic control & automatic
defrost control These parts can
produce a snapping or clicking
sound when turning the cooling
system on and o.
F Compressor High-eciency
compressors run much faster
than previous models. The
compressor may have a
noticeable hum or pulsating
sound during operation.
G Water valves They make a
buzzing sound each time they
open to fill the ice maker.
H Drain pan (not removable)
