NORMAL OPERATING SOUNDS

NOTE
Rigid foam insulation is very energy
ecient but is not a sound insulator.
Understanding the sounds you
may hear
Your new, high-eciency 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.

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.
E Condenser fan You may hear air
being forced through the condenser.
F Compressor Modern, high-eciency
compressors run much faster than in
the past. The compressor may have a
high-pitched hum or pulsating sound.
G 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.
H Drain pan (not removable) You may
hear water dripping into the drain
pan during the defrost cycle.
I Condenser The condenser may create
minimal sounds from forced air.
IMPORTANT
Ice Maker models only:
If the ice maker is not connected to the
household water supply, you may hear
a loud chattering noise. Turn o the ice
maker by pressing the green ON/ OFF
power switch (green LED light will turn
o) until you install the water supply line.
