Normal Operating Sounds

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.
Rigid foam insulation is very energy
efficient, but is not a sound insulator.
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.
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
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 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
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-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 (Non-removable)
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). The pan is maintenance-
free because the amount of water
that collects in the pan is not enough
to overflow before evaporating.
J. Condenser Coils (Fan-cooled models only)
You may hear air being forced
through the condenser coils.
