Operating Sounds

Today's freezers are designed for economical operation and energy efficiency. New features and designs may create
sounds which are different. Following are normal operating sounds which may be encountered, no service call is
required.
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.

Defrost heater:*
Sizzling, hissing, or popping sounds are caused by water
