Fig. 10 — Supply Fan Control Wiring Diagram

Removing the Motor and Fan Assembly

NOTE: Due to press fit design of composite Rotor on Motor, it is

highly recommended that any time a motor is replaced the fan

rotor is replaced as well. The rest of the assembly may be reused. 
See Fig. 11.
1. Unplug motor harness from control box harness and cut

wire tie at the fan deck.

2. Unplug connectors from stator temperature limit switch.

3. Remove two screws at front of stator on fan deck.

4. Slide fan assembly forward a couple of inches to clear rear

brackets and lift assembly out.

Fig. 11 — Fan Assembly Removal

Disassembling Motor and Fan Assembly

See Fig. 12.

1. Remove six screws from retaining rings in the top of the

fan rotor.

2. Remove rotor from motor.

3. Remove four screws connecting motor to stator flange.
4. Remove stator from motor.

5. If required, remove stator limit switch on aluminum stator.

6. Remove three screws from the heat shield. Retain the heat

shield if a new heat shield has not been ordered.
