NORMAL OPERATING SOUNDS
Understanding the Sounds you
may Hear
Your new, high-eciency unit may intro-
duce unfamiliar sounds. These sounds
normally indicate your appliance is oper-
ating correctly. Some surfaces on floors,
walls, and kitchen cabinets may make
these sounds more noticeable.
Following is a list of major components
in your unit 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 be-
ing 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 Compressor Modern, high-eciency
compressors run much faster than in
the past. The compressor may have a
high-pitched hum or pulsating sound.
E Drain pan (not removable) You may
hear water dripping into the drain
pan during the defrost cycle.
F Motorized damper May produce in-
termittent humming during operation.

glow in the back wall vents of your
freezer compartment is normal.
