NORMAL OPERATING SOUNDS AND SIGHTS
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.

from forced air.

humming during operation.
