In the vast majority of cases like you are explaining, the system board is the issue. It's not sensing the signal from the ingnitor to say that it lit and is still lit.
Thanks - is there a way to 100% confirm the systemboard issue through diagnostics, however? I've always been a big proponent of diagnostics to confirm something is broken or not working as it should before replacing it, especially when said part is going to cost me $200 or so by the time I get it to my door.
I'd hate to throw a $200 part at the heater only to discover afterwards it's doing the exact same thing.
