Understanding the Sounds you
may Hear
Your new, high-efciency refrigerator may
introduce unfamiliar sounds. These sounds
normally indicate your refrigerator is operating
correctly. Some surfaces on oors, walls, and
kitchen cabinets may make these sounds
more noticeable.
Following is a list of major components in your
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 air
being forced through the refrigerator
by the evaporator fan.
C. Defrost heater During defrost cycles,
water dripping onto the defrost heater may
cause a hissing or sizzling sound. After
defrosting, a popping sound may occur.
D. Automatic ice maker When ice has
been produced, you will hear ice cubes
falling into the ice bin.
E. Electronic control & automatic
defrost control These parts can
produce a snapping or clicking sound
when turning the cooling system on
and off.
F. Condenser fan You may hear air
being forced through the condenser.
G. Compressor Modern, high-efciency
compressors run much faster than in
the past. The compressor may have a
high-pitched hum or pulsating sound.
H. Water valve Makes a buzzing sound
each time it opens to ll the ice maker.
I. Drain pan (not removable) You may
hear water dripping into the drain pan
during the defrost cycle.
J. Condenser May create minimal
sounds from forced air.
K. Motorized damper May produce a
light humming during operation.
L. Ice chute When dispensing ice, you
will hear a snapping or clicking sound
when the solenoid opens and closes the
ice chute.
