Normal Operating Sounds
Understanding the sounds you
may hear
Your new, high-effi ciency refrigerator may introduce
unfamiliar sounds. These sounds normally indicate your
refrigerator is operating correctly. Some surfaces on fl oors,
walls, and kitchen cabinets may make these sounds more
noticeable.
The 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. Ice
maker fan, water valve activation, and refrigerant gas
fl uid 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 off.
F Condenser fan You may hear air being forced
through the condenser.
G Compressor Modern, high-effi ciency compressors
run much faster than older models. The compressor
may have a high-pitched hum or pulsating sound.
H Water valve Makes a buzzing sound each time it
opens to fi 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 Temperature Adjustable Cold Zone
drawer damper May produce a light humming
during operation.
L Ice dispensing paddle When dispensing ice, you
will hear a snapping, clicking, or popping sound when
the solenoid opens and closes the ice chute.
M Motorized damper May produce a light humming
during operation.
N Temperature Adjustable Cold Zone drawer fan
Turns off when door opens or the Cold Zone drawer is
turned off.
NOTE
During automatic defrost cycle, a red glow in the back wall
vents of your freezer compartment is normal.
NOTE
Energy effi cient foam in your refrigerator is not a sound
insulator.
