Harman PF100 6 blink from hell

[miata91!]

The manual talks about draft control but damed if I can find anything about it but may be like
most harmans a flap on the air intake. It may be stuck open

Yes, I see they have a little draft control setting on the motherboard, but I have no idea how that works and what it uses to control the draft

So I have a Harman PF 100 furnace with a red probe and I have a 6 blink error code that I cannot seem to get fixed. I have recently replaced the motherboard and I have a 6 RPM auger motor on it. I have went through everything I can find on the forums and talking to a couple different companies. I do not appear to have any gaskets or seals leaking. I do not have a fresh air intake hooked up but The intake flapper is clearly operating. It seems to be feeding pellets perfectly fine. I’ve messed with the draft settings on the motherboard. I do not have a clog in anything that I can find. I’ve cleaned everything from the convection fan, the shaker chains, the burn pot, and the auger housing. I’m at a complete loss as to why it continues to blink. it usually flashes the error code and shuts down within 25 minutes to 2 hours, and it does not blow very warm air out the vents before shutting down. Any help or suggestions would be greatly appreciated!

I just attach some photos to my original post if you would like to review those

I’m attaching some photos of my burn pot right after removal if I’m not mistaken the orange looking staining would be a potential air leak, correct?
