To start everything worked fine but the blower motor wouldn't come on. Everything else worked (board/pre vent/flame) so had original wiring diagram and made my own just in case. Got blower motor out, tested it, it was bad, so replaced it with a new comp. Re installed wires to correct spots. Now no power anywhere (board won't come on and no blinking light) breaker is on/emergency switch is on/push button is in. I tested the push button it's good. I tested the power before the push button I have power. I want to think board went bad but it worked before so I'm confused... I have a goodman gmp050-3 also who ever helps do you know the correct replacement type for the board if you think that's it?

PS I really appreciate everyone who takes the time to help on here.

Thank you

The board may have a small automotive type fuse usually either 3 or 5 amp.

Checked fuze... Sorry I didn't put in post

Check for 120 volts coming into the board. If you have 120 in, no 24 volts out, & the fuse is good, I'd have to say bad board.
