Understanding the Sounds You May Hear
Your new, high-efficiency refrigerator may introduce
unfamiliar sounds. These sounds normally indicate your
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 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
and water valve activation may create sounds from its
operation. (Freezer ice maker in select models only).
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-efficiency 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 fill 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.
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.
Normal Operating Sounds and Sights
NOTE
Energy efficient foam in your refrigerator is not a sound
insulator.
NOTE
During automatic defrost cycle, a red glow in the back wall
vents of your freezer compartment is normal.
