Normal Operating Sights & Sounds
Understanding The Sounds You May Hear
NOTE:
Rigid foam insulation in modern
refrigerators 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.
Your new high-efficiency refrigerator may make
unfamiliar sounds. Dont be alarmed, these are all
normal sounds. 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 & Defrost Timer
These parts can produce a snapping or clicking
sound when turning the refrigerator on and off. The
timer also produces sounds similar to an electric
clock.
F. Condenser Fan
If condenser coils are located underneath your
refrigerator as shown in the drawing at the right, you
have a 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.
I. Drain Pan
You may hear water running into the drain pan
during the defrost cycle.
