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 intro-
duce unfamiliar sounds. These sounds normally
indicate your refrigerator is operating correctly.
Some surfaces on oors, walls, and kitchen cabi-
nets 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 gur-
gling 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.

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.
D Automatic ice maker When ice has
been produced, you will hear ice cubes
falling into the ice bin.
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 ll 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 The condenser may create
minimal sounds from forced air.
