Normal Operating Sounds - Maytag TM-1 User Manual

NORMAL 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
overall. 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 refrig-
erator.
DEFROST TIMER: Frost-free
refrigerators have a defrost timer
that will generate a clicking
sound when it cycles the unit into
and out of defrost cycle.
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.
efficiency compressor may run longer
and generate sounds such as a higher
pitched hum or pulsation.

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.
That new, high
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 unit is cooled.
WATER VALVE (if equipped): A buzzing
sound may be detected in the back of the
unit when the ice dispenser calls for the
water valve to open to fill the ice maker
tray. Following the ejection of the 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 wheels or levelers properly.
FREEZER COMPARTMENT
CONTRACTION AND EX-
PANSION: 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.
