Normal Operating Sounds
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.

through the condenser.

compressors run much faster than older models.
The compressor may have a high-pitched hum or
pulsating sound.

opens to fill the ice maker.
I Drain pan (not removable) You may hear water
dripping into the drain pan during the defrost
cycle.
