Understanding The Sounds You
May Hear
Yournewhigh-efciencyrefrigeratormay
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
woodoors,walls,andkitchencabinetsmay
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
Theowofrefrigerantthroughthe
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
Ifyourrefrigeratorisequippedwithan
automatic ice maker, you will hear ice
cubes falling into the ice bin.
E. Cold Control & Defrost Timer or
Automatic Defrost Control
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 left, you have a condenser fan. You
may hear air being forced through the
condenser by the condenser fan.
G. Compressor
Modern,high-efciencycompressors
operate much faster than older models.
The compressor may have a high-pitched
hum or pulsating sound.
H. Water Valve

automatic ice maker, you will hear a
buzzing sound as the water valve opens to
lltheicemakerduringeachcycle.
I. Drain Pan (Nonremovable)
You may hear water running into the
drain pan during the defrost cycle. The
drain pan will be located on top of the
compressor for air-cooled condensers
(black coils on back of refrigerator).
J. Condenser Coils (Fan-cooled models
only)
May create minimal sounds from forced air.
