I have installed old furnace in garage temped it first ran fine
While setting permanent tipped it and broke inducer motor
Installed new one now I'm getting rapid flashing or polarity is wrong
I ran wire myself so I know that's not the problem what would be the next step
To check ? The wires r correct on board even tryed swapping secondary wire just for giggles. Any ideas would help. Thanks

Did you make sure it has a good grounded connection too?
