The main ignition control board checks the main gas intake valve, the igniter and some more sensing equipment. It has been a very important board that is now usually a standard part of the main board instead of a separate board.
What symptoms are present when the main ignition board has to be replaced?
- Signal from main thermostat never moves to the main control board
- The ignition cycle is unwilling to kick in no matter what
- Every other potential issue connected to the system is inspected and turns out to be fine
