I have a Goodman GMP075-4.My fan started making a lot of noise that sounded like metal on metal.Eventually the fan motor burned up and quit. I took many detailed pictures andmade notes as to what was hooked up where. I also labeled all of thewires on the old fan as I disconnected them.
I ordered another one identical to the one I removed. I labeled the wires on the new fan motor just as the old one. I installed the new one exactly as theoriginal had been installed to the wire.
The current problem is this:
Once the motor was installed, the fan would not come on. I turned it onin the heat and in the A/C mode. The indicator light showed a "rapidcontinuous" flashing. This indicates that the Equipment Problem maybe:

A) "Incorrect Twinning" and to check "ReverseTransformer Secondary Leads"

B) "Incorrect Primary Polarity" and to check "Reverse PrimaryWires"

I reversed the white Neutral wire and the blue M1 wire. This had no effect. Ireplaced the white Neutral wire to its original location and placed the blue M1wire into the M2 connector. This had no effect. I have now placed all of thewires back into the original locations and am stuck. Any assistance would begreatly appreciated
