NOTE
Rigid foam insulation is very energy efficient, but is not
a sound insulator.
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.
IMPORTANT
During the automatic defrost cycle, you may notice a
red glow in the vents on the back wall of your freezer
compartment. This is normal during the defrost cycle.
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. The ice maker will produce 2.5 to 3
pounds of ice every 24 hours depending on usage
conditions.
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 in the past. 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.
