No heat, just returns to clock

[mfpsky1]

Can’t figure this one out, Dacor cps130 everything works in diagnostic mode, all coils heat, fan and convection work. When not in diagnostic mode, I choose any of the heat modes, and set temp,I hear a relay click, fan kicks on, and after a few seconds returns to clock, no heat. I even checked the high temp switch with the power off, it has continuity. I can’t find a wire diagram. Any help or ideas would be greatly appreciated.
