NORMAL OPERATING SOUNDS
NOTE
Rigid foam insulation is very energy
ecient but is not a sound insulator.
Understanding the sounds you
may hear
Your new, high-eciency 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.
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.
E Automatic Defrost control These
parts can produce a snapping or
clicking sound when turning the
cooling system on and o.
F Condenser fan You may hear air
being forced through the condenser.
G Compressor Modern, high-eciency
compressors run much faster than
in the past. The compressor
may have a high-pitched hum or
pulsating sound.
H Water valve If your refrigerator is
equipped with an automatic ice
maker, you will hear a buzzing sound
as the water valve opens to fill the
ice maker during each cycle.
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.
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.
