Steve,
I think you solved part of the mystery. I just looked at the burned board and there is no nylon screw on either of the 120V terminals. Who knows where / when they came out but the connection is definitely not robust without some sort of physical assist to the solder joints.
Gurus….IF YOU HAVE SCS basement AC units, check that you have the nylon screw holding the 120V power terminals to the board. Missing them could cause you a fire.
Thanks Steve!
