An ignition control board governs the gas valve, the ignition sequence and the flame sensing circuits. The ignition control board was always an important board that is now usually a vital part of the main control board instead of its own individual board.
Elements of a barely functioning ignition control board
- Every other device within the system checked out to be just fine
- Communication from the remote thermostat does not show up at the main board
- The ignition system refuses to fire up no matter what
