NOTE
Rigid foam insulation is very energy
ecient but is not a sound insulator.
Understanding the sounds you
may hear
Your new, high-eciency 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.

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.

parts can produce a snapping or
clicking sound when turning the
cooling system on and o.
E Compressor Modern, high-eciency
compressors run much faster than in
the past. The compressor may have a
high-pitched hum or pulsating sound.

hear water dripping into the drain
pan during the defrost cycle.
