How to Remove the Blower Motor in a Trane XL80

Turn off the air handler's power, either at the breaker inside the air handler or at the main breaker box.

Remove the nuts and open the air handler access panel.

Follow the bound group of wiring from the side of the air handler up to the base of the motor and disconnect the wiring.

Unscrew the two front screws of the blower assembly. Slide the assembly forward to unhook it from the mounting screws.

Sit the assembly on the ground with the bottom of the motor facing up. Loosen the 3 bolts that hold the motor to the blower.

Flip over the assembly over and loosen the nut around the base of the shaft.

Lift up the assembly. The motor will slide out.
