NOTE
Rigid foam insulation is very energy ef-
cient, but is not a sound insulator.
Understanding the sounds you
may hear
Your new, high-efciency refrigerator may
introduce unfamiliar sounds. These sounds
normally indicate your refrigerator is operating
correctly. Some surfaces on oors, walls, and
kitchen cabinets may make these sounds more
noticeable.
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.
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.
D Automatic defrost control These parts
can produce a snapping or clicking sound
when turning the cooling system on and off.
E Compressor Modern, high-efciency
compressors run much faster than in the
past. The compressor may have a high-
pitched hum or pulsating sound.
F Drain pan (not removable) You may hear
water dripping into the drain pan during
the defrost cycle.
