Recent improvements in refrigeration design may introduce sounds in your new refrigerator that were not noticed in earlier models.
These improvements were made to create a refrigerator that will preserve food better, run more energy efficiently, and perform quieter
overall. Because new refrigerator designs run quieter than past models you may start to detect sounds that were actually present in your
older model but were typically masked by the refrigerator’s higher sound levels. Many of these sounds are normal. The following are
some of the normal sounds your new refrigerator may make:
REFRIGERANT FLOW: The flow of the
cooling fluid in your freezer area may cause
gurgling or quiet knocking sounds when the
refrigerator cycles on or off.
WATER VALVES: You may
detect a slight buzzing sound
under the refrigerator when
water is requested from the ice
dispenser or when the ice maker
needs water to make ice.
CABINET LEVELING: An unlevel
cabinet may cause rattles and
vibration noises.
AIRFLOW SOUNDS:
There are a number of
fans in the refrigerator
that make airflow sounds
when in operation. The
freezer fan circulates
cool air throughout the
refrigerator. The refrig-
erator circulating fan
helps keep that com-
partment's temperature
more uniform. The
condenser fan on top of
your refrigerator is
utilized to remove the
heat generated by the
refrigeration system.
Lastly, the Climate Zone
compartments circulate
air to maintain optimum
temperatures.
COMPRESSOR: The
compressor on this
unit has a variable
speed motor. This
variability allows the
system to adjust to
different usage needs.
This will introduce
speed change sounds
and some higher
pitched humming
sounds that are
normal for the
operation of this type
of compressor.
ICE MAKER: The cabinet
will occasionally generate a
rattling sound when ice
cubes are ejected into the
freezer ice bin. You may
also detect the motor that is
ejecting that ice. These are
normal sounds necessary for
ice making.
CONTROL SWITCHES: In
the electronics control area
there are numerous control
switches that make a quiet
clicking sound when you use
your refrigerator or during
some of the normal system
operations.
