Normal Operating Sounds
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.
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 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-efciency 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
ll the ice maker.
I Drain pan (not removable) You may hear water dripping
into the drain pan during the defrost cycle.

when door opens or the Cold Zone drawer is turned off.
