I cant see your wire diagram but trace the circut your talking about. I believe it usually goes through a series of safety switches. Put your VOM across each individual switch. If you get 24 out from the board the first 1 you check and get 24v is open and not feeding back to the board is out. FIND out why. the switch could be bad but it may be indicating a more involved problem, just look aroeund for chared wires or tell tell signes of flame roll out or if its an open (fuse link) suspect what can cause an over heat condition anythign from a bad board or too long an off cycle before the indoor fan comes on ect. PONIT IS Once you come across the cause may not be the reason.
Please grade me accordingly and if you need more I need more info from you.
