General Tips
Operating Sounds
Todays freezers are designed for economical operation and energy efficiency. New features and designs may create
sounds which are different. Following is normal operating sounds which may be encountered, no service call is
required.
Defrost heater:*
Sizzling, hissing, or popping sounds are caused by water
dropping on the defrost heater during the defrost cycle.
Evaporator:
Gurgling sound, like boiling
water, when refrigerent flows
through the freezer cooling
coil.
Freezer fan:*
Makes a whirring noise
or sounds like rushing
air as cold air ciculates in
the freezer compartment.
Compressor:
Runs faster for higher
efficiency and has
a higher pitched hum
or pulsating sound.
Defrost drain pan:*
Dripping sound is defrost
water falling onto drain pan.
Temperature control:
Clicks when the compressor
starts or stops.
Defrost timer:*
Automatic timer sounds like an
electric clock that snaps in and
out of the defrost cycle.
Insulation:
High-efficiency foam is used for
its excellent energy insulation
capacity, even though it does not
offer the same level of sound
insulation as less energy-efficient
fiberglass insulation once found
in freezers.
