When I turn the thermostat up...goes click, stove goes click, combustion fan turns on....call light stays off. I turn thermostat off then back on a few times then call light comes on. I know its a snap disc, but which one? Quad part #?

Thank you! :cool:

Not so sure it is a snap disk. The call light should come on before the combustion fan. However, take the thermostat out of the equation by first putting a jumper across the terminals and see if the stove works properly then. If so, it is your thermostat. If not, then we can troubleshoot further.

I will do that. But what could it be?
 
Could be a balky relay on the control board - if there is one. This is a typical symptom of such. You could try tapping the board (not TOO hard, but firmly) when you first hit the thermostat. Could also be a flaky connection on or to the board.
