34 Normal Operating Sounds & Sights
Understanding the sounds you may hear
Your new, high-efficiency 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.
D Automatic ice maker When ice has
been produced, you will hear ice cubes
falling into the ice bin.
E Electronic control & automatic
defrost control These parts can
produce a snapping or clicking sound
when turning the cooling system on and
off.
F Condenser fan You may hear air being
forced through the condenser.
G Compressor Modern, high-efficiency
compressors run much faster than in the
past. The compressor may have a high-
pitched hum or pulsating sound.
H Water valve Makes a buzzing sound
each time it opens to fill the ice maker.
I Drain pan (not removable) You may hear
water dripping into the drain pan during
the defrost cycle.
J Condenser May create minimal sounds
from forced air.
K Motorized damper May produce a light
humming during operation.
L Ice dispensing paddle When
dispensing ice, you will hear a snapping
or clicking sound when the solenoid
opens and closes the ice chute.
NOTE
During automatic defrost cycle, a red
glow in the back wall vents of your freezer
compartment is normal.
NOTE
Energy efficient foam in your refrigerator is
not a sound insulator.
M Perfect Temp
TM
Drawer (some
models) Fans run intermittently when
door is closed but turn off when door is
opened (except when fridge is in Sabbath
Mode). Air control valve may produce a
light humming during operation.
