Before testing the condensor fan, unplug
the refrigerator to avoid an electrical shock hazard.
The condensor fan is located behind the refrigerator.
It may be necessary to remove an access panel to reach it.
Clean the fan. If the fan blade is damaged,
it can be removed from the fan motor and it should be replaced.
Spin the fan blade, it should move smoothly
and freely. If the fan does not move smoothly, replace
the fan motor.
If the fan motor cannot be accessed for
testing, remove the motor now. The fan motor is held in place
with screws and possibly a mounting bracket. Remove the bracket
and the screws and pull the motor back away from the housing.
