SOLUTION
The shelves must never be
covered with any type of plastic
or other material that will block
the circulation of cold air within
the refrigerator.
Check to see if condensation or
ice crystals have formed on the
suction line. If so, charge with
the correct amount of gas.
Find the location where the gas
is leaking in order to seal it or
replace the defective
component. Change the drier.
Perform a good vacuum and
recharge the unit.
Check the electrical
connections and make sure
that the fan blade isn't stuck.
Replace the fan motor if it
doesn't work.
Use a voltage regulator if the
voltage is lower than 103 volts.
Check for appropriate
insulation on the connections of
each electrical component.
Check if the noise goes away
after you level the refrigerator.
While the compressor is
working, check to see if metal
parts are in contact with one
another and/or if the screws
that fasten the condenser are
tightened.
Check if the fans are securely
fastened. Also, check if the fan
blades are loose, broken or
crooked. If so, change the
faulty blade.
If the noise persists after all
other measures have been
taken, it may be originating
from the compressor.
Set the thermostat knob to a
warmer position and check if
the compressor stops
according to the thermostat's
operating range.
This type of occurrence is
caused by local climatic
conditions and not by the
refrigerated unit.
