NORMAL OPERATING SOUNDS
Understanding the sounds
coming from the refrigerator
High-efficiency refrigerators may
introduce
unfamiliar sounds
. These
sounds normally indicate the 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 the refrigerator and the
sounds they can cause:
A
Evaporator
Refrigerant through
the evaporator may create a
boiling or gurgling
sound.
B
Evaporator fan
Sounds of
air
being forced
through the
refrigerator by the evaporator
fan may be heard.
C
Defrost heaters
During defrost
cycles, water dripping onto the
defrost heaters may cause a
hissing or sizzling
sound. After
defrosting, a popping sound
may occur.
D
Automatic ice maker
When
ice has been produced, sounds
of
ice cubes falling
into the
ice bin may be heard. The 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
Compressor
Modern, high-
efficiency compressors run much
faster than older models. The
compressor may have a
high-
pitched hum or pulsating
sound.
G
Water valves
Make a
buzzing
sound each time they open to fill
the ice maker.
H
Drain pan
(not removable)
Sounds of
water dripping
into
the drain pan during the defrost
cycle may be heard.
I
Condenser
May create minimal
sounds from
forced air
.
J
Motorized damper
May produce
a
light humming
during operation.
NOTE
Energy efficient foam in the refrigerator
is not a sound insulator.
NOTE
During automatic defrost cycle, a red
glow in the back wall vents of the freez-
er compartment is normal.
