D102E749

Inspection / Measurement

1. Inspect the rotor assembly.

D

Test the rotor coil for an open circuit by using the
ohmmeter. The reading should be sufficiently low,
or the rotor must be replaced (1).

D102E750

D

Test the rotor for open or short circuits. The read-
ing should be 2.6 to 2.8 ohms, or the rotor should
be replaced (2).

D

Test the rotor for open or ground circuits by using
the ohmmeter. The reading should be sufficiently
high, or the rotor must be replaced (3).

D

Inspect the fan blade for damage.

D102E751

2. Inspect the stator.

D

Test the rotor for an open circuit by using the ohm-
meter. The reading should be sufficiently low, or
the stator must be replaced (1).
