Normal Operating Sounds - Crosley CRD2121NW Guía De Uso Y Cuidado

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 refrigerator.
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.
CABINET LEVELING: An unlevel cabinet
may cause rattling or vibrating noises.
This can be fixed by adjusting the wheels
or levelers properly.
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
during defrost.
FREEZER COMPARTMENT
CONTRACTION AND EXPAN-
SION: A popping sound may
occur in the freezer when the
unit starts up due
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 unit is cooled.
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.
