NORMAL OPERATING SOUNDS & SIGHTS
UNDERSTANDING THE SOUNDS YOU MAY
HEAR
Your new high-efficiency refrigerator may make unfamiliar
sounds. These are all normal sounds and soon will become
familiar to you. They also indicate your refrigerator is operating
as designed. Hard surfaces, such as vinyl or wood floors, walls,
and kitchen cabinets may make sounds more noticeable. Listed
below are descriptions of some of the most common sounds
you may hear, and what is causing them.
A. Evaporator
The flow of 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
If your refrigerator is equipped with an automatic ice
maker, you will hear ice cubes falling into the ice bin.
E. Cold Control & Automatic Defrost Control
These parts can produce a snapping or clicking sound
when turning the refrigerator on and off.
F. Condenser Fan
You may hear air being forced through the condenser
by the condenser fan.
G. Compressor
Modern, high-efficiency compressors operate much
faster than older models. 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.

NOTE
Rigid foam insulation is very energy efficient, but is not a
sound insulator.
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.
IMPORTANT
Your ice maker is turned On at the factory so it can work as soon
as you install your refrigerator. To ensure proper function of your
ice maker, connect a water supply immediately or turn the Ice
maker off by lifting the wire signal arm to the “up” or OFF position
(side mounted) or the ice maker’s On/Off power switch turned Off-
set to the “
O” position (rear mounted) .
I. Drain Pan (not removable)
You may hear water running into the drain pan during
the defrost cycle.
J. Condenser
May create minimal sounds from forced air.
K. Motorized Damper
May produce a light humming during operation.
