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, 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 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.
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.
M Motorized damper
May produce a
light humming during operation.
