Can anyone tell me where I may purchase parts for a Rheem Classic Airconditioning unit? I am in need of a Fan motor and a capicator.

Thank you

The parts are available in many places. You will need to remove the motor and capacitor and have them matched up for speed (RPM's) and horse power.
The new motor will probably have a rotation change plug or the wiring diagram on the motor will tell you how to change the rotation so the air blows out of the unit.

If you do not know what you are doing with electric and wiring you might want to consider professional help and call for service.
