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.
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.

Condenser
May create minimal sounds from
forced air.
K
Motorized Custom Temp

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.

During automatic defrost cycle, a red glow in the back
wall vents of your freezer compartment is normal.
NOTE
Energy efficient foam in your refrigerator is not a
sound insulator.
