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.
L
Ice dispensing paddle
When dispensing ice, 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.
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.
