NOTE: Stepper motors require alternating polarities of
DC current to operate. Applying straight 12 VDC to
the damper motor will not make the motor run and it
could damage the motor windings. Only test the
damper motor through the refrigerator control system.
To test, set the control system into service test mode 2
(evaporator fan motor test) and allow the fan to run on
high speed. Pass a feather or small ribbon around all
sides of the damper cover and look for movement
indicating an air leak. If an air leak is present, remove
and recheck the seals, then reinstall the damper.
