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
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.
