The Problem Solver
Stainless Steel Refrigerator
Normal
operating
sounds
These sounds are normal and are due
mostly to highly efficient operation.
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.
The new high efficiency compressor runs
faster and will have a higher pitch hum or
pulsating sound while operating.
Defrost timer and refrigerator control click
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 coils 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.
