NORMAL OPERATING SOUNDS
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.
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-efficiency
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 off the ice
maker by pressing the green ON/ OFF
power switch (green LED light will turn
off) until you install the water supply line.
