Lol yes I know, even the tech that came out and redid the gas valve suggested it could be board. I just got tired of throwing parts at it without some understanding this time. None the less, almost the entire thing has been replaced. But good learning experience for me.

Yup, 3 speed blower motor, low, med, and high . One speed for heat, one for air, and the other parks on the spare terminal. Good job glad to help

Lol I did have a pucker moment hoping I did it right.

Now the fun part of understanding what happened is to rip the old fan relay off the board and look at the burned up fan relay contacts, if you want to see them. you will have to break the black relay box open to see them.

Not sure what I’m looking for but the only thing that around out is that yellowish/orange stuff

It wasn’t the relay, it was this capacitor.. I see the burn mark

Right in the center big blue one has a burn around it

That looks like the relay contacts there. They should look burnt

And it’s the black relay with the ‘M’ on it

Make sure you remove that tape that is holding the door safety switch closed. You don't want to mix combustion air with recirculating air. Good job on fixing it yourself. So sad that a "tech" threw parts at your furnace instead of diagnosing it. That was an easy one for a real tech.

Like many forums, there's a lot of talent here. Good to see the moderators let this run its course. A friend just went thru this on his HVAC at his house on the high desert. He called me for help. Unfortunately, I probably wasn't much help. He got a board, which was his suspicion from the start, and it was fixed.

No burn marks on relay

But check this out.. burn marks on the board
