York Diamond 80 Problems

My York Diamond 80 won't light. Here is what has transpired:

It would run correctly, but kept blowing 10A fuses. I'd replace and it would run for a few hours and then blow fuse again.
This went on for a few days. Then, it wouldn't light. There is only one flash on the LED when it starts, then nothing. The ignitor glows red, but nothing else happens - no fan, no gas, no flame, and it won't cycle out of this mode - it just keeps on with the ignitor bright red.

I'm thinking the circuit board is blown, but how do I confirm this?

Thanks hvac4u for the reply.

Any clue why it would blow fuses? Something on the board drawing too much current?

thanks,

low volt short, probably in a fan relay.

in heat a lot of times it is the inducer motor relay.

i have fixed them in the past, now it is cheaper to replace the board

Thanks for the replies. Seems to be be "new board time". I've found a local source (Denver area) where I can get the board for $180.
