Im working on a Goodman indoor unit Model #AEPT030-00C-1A. The fan is a varible speed fan motor. The control Module/board has the 24 volts coming into it. The fan motor has the high voltage going into it but it wont come on. I believe the motor to be shot. I also checked the continuity of the motor and it was open. Ive changed many single speed motors but never a varible speed. Is there and other things i should check before getting one the these motors.
