Normam Operating Sounds
Improvements in refrigeration design may produce sounds in your new refrigerator that are different or were not
present in an older model These improvements were made to create a refrigerator that is better at preserving food,
is more energy efficient, and is quieter overa& Because new units run quieter, sounds may be detected that were
present in older units, but were masked by higher sound levels. Many of these sounds are normal. Please note that
the surfaces adjacent to a refrigerator, such as hard walls, floors and cabinetry may make these sounds seem even
louder. The following are some of the normal sounds that may be noticed in a new refrigerator.
TIMER: Frost-free]
refrigerators have a defrost timer|
that will generate a clicking|
sound when it cycles the unit_
nto and out of defrost cyc e. [
ICE MAKER: [if equipped) The ice maker]
will occasionally generate a rattling sound|
when the ice cubes are ready to drop down_
into the ice bin. Also, the motor that ejects|
the ice from its tray prior to dropping the|
ice may also be detectable. These are|
normal sounds necessary for making ice.
DEFROST HEATER: During
the automatic defrost cycle, a
sizzling sound may be heard
as water droplets come into
contact with the defrost
heater. This is a normal
sound heard dur ng defrost.
FREEZER COMPARTMENT
CONTRACTION AND EXPAN-
SION: A popping sound may
occur in the freezer when the
unit starts up due to contraction
or expansion of the materials in
the freezer area.
REFRIGERANT FLOW: The flow of the
refrigerant in your refrigerator may cause a
gurgling or rattling sound when the unit is
running or just after the unit cycles off. The
refrigerant is still flowing in the tubing.
AIRFLOW SOUNDS: Both the freezer]
evaporator fan and the condenser fan at the /
bottom of the cabinet will create airflow /
sounds. The evaporator fan is circulating the
cold air throughout the refrigerator and freezer /
compartments. The condenser fan is removing
the heat generated when the un t s coo ed.
COMPRESSOR: In order for a new
refrigerator to run more efficiently,
the refrigeration system may run
longer to keep food at the desired
temperatures for freshness. That
new, high efficiency compressor may
run longer and generate sounds such
as a higher pitched hum or pulsation.
q
WATER VALVE (if equipped): A buzzing[
sound may be detected in the back of_
the unit when the ice dispenser calls foq
the water valve to open to fill the ice I
maker tray. Following the ejection of the I
ice, there may be some water dripping|
sounds when the trays are being filled.
CABINET LEVELING: An unlevel
cabinet may cause rattling or vibrating
noises. This can be fixed by adjusting
the whee s or eve ers proper y.
