If you mean the blower wheel, I wonder how you diagnosed this problem so you were 100% sure the motor is bad. I recommend to make sure of the diagnosis before spending to buy parts.
The blower wheel is shaped like a twin blade. But it's only one wheel.
However, to answer the question; Step one is turn the power off.
Then; Find the blower housing in the lower compartment on an upflow configuration.
- Remove 2 screws on the blower housing, on the upper inside of the blower compartment to slide the blower housing out.
- Disconnect blower motor wiring at the harness and at the control board if connected. You can cut them if you have exact replacement motor and wire nuts.
- Slide the housing out, turning it on the side that exposes the motor.
- Remove the 3 mounting screws holding the motor to the housing.
- Loosen the lock nut holding the fan blade (wheel) to motor shaft.
- Slide motor and shaft out and away from the fan blade, as they are connected together and cannot be separated. Use penetrating oil SPARINGLY.
Installation is the reverse of the removal instructions.
IMPORTANT. Make sure to leave equal space between both sides of fan blade and housing when re-installing the wheel.
Luck to you. Let me know how that turns out.
