Normal Operating Sounds - GE Profile Series Owner's Manual

Normal operating sounds.

Depending on the placement of the refrigerator in your kitchen,
you may want to place a piece of rubber backed carpet under the
refrigerator to reduce noise.
These sounds are normal
and are due mostly to highly
efficient operation.
The new high efficiency compressor runs faster
and will have a higher pitch hum or pulsating
sound while operating.
Defrost timer and refrigerator control clicks on
and off.
The fan circulating air inside the freezer which
keeps the temperatures throughout.
Water dropping on the defrost heater causing a
sizzling, hissing or popping sound during the
defrost cycle.
The flow of refrigerant through the freezer
cooling coil sounds like boiling water or a
gurgling noise.
Cracking or popping of cooling coils caused by
expansion and contraction during defrost and
refrigeration following defrost.
Water dripping as it melts from the evaporator
and flows to the drain pan during the defrost
cycle.
Icemaker
(on some models)
The icemaker water valve will buzz when the
icemaker fills with water. If the feeler arm is in
the ON (down) position it will buzz even if it
has not yet been hooked up to water. Keeping
the feeler arm in the ON (down) position before
it is hooked up to water can damage the
icemaker. To prevent this, raise the feeler arm
to the STOP (up) position. This will stop the
buzzing.
The sound of cubes dropping into the bin and
water running in pipes as icemaker refills.
