CLEANING
Wipe all dust or dirt from the fan, motor, and housing.
INSPECTION
1. Check that all parts are properly placed and in good condition.
2. Inspect the fan for damaged or bent blades and check the motor for signs of overheating. Check all
mounting hardware for tightness.
3. Disconnect the P3 motor connector plug and check for loose, damaged, or missing pins.
4. Inspect the fan's housing for damage and for missing or defective hardware.
TESTING
1. The motor is capable of operating at two speeds; therefore, there are two sets of field coils.
2. Use an ohmmeter or continuity tester and check the continuity at P3 between pins A and B, A and
C, D and E, and E and F. Continuity should exist. If continuity does not exist, allow the motor to
cool and retest. If continuity continues to not exist, replace the motor.
3. Check the continuity at P3 from pin G to pins A, B, C, D, E, and F. Continuity should not exist. If
continuity does exist, replace the motor.
