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 of gas leak in order to
seal and replace the defective
component. Change the drier. Perform
a good vacuum and recharge unit
Check electrical connections and make
sure that the fan blade isn't stuck.
Replace the fan motor if it doesn't
work.
Re-arrange product to allow for proper
air flow. Make sure there is at least four
inches of clearance from the
evaporator.
Check for appropriate insulation on the
connections of each 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 cracked. If so,
change the faulty blade
If the noise persists after all other
measures have been taken, it may be
originating from the compressor.
Locate and tighten loose part(s)
Set the controller to a warmer
position & check to see if compressor
stops as should
This type of occurrence is caused by
local climatic conditions and not by the
refrigeration unit
Check the door and/or the magnetic
gasket. Adjust the door hinges if
needed; replace the gasket if broken
