The main ignition control board manages the main gas intake valve, the igniter and some more sensing equipment. It is an important electronic circuit board that is usually a vital part of the main control board instead of a separate board.
Warnings to watch for in a bad ignition board
- Ignition sequence is unwilling to commence even though it is supposed to
- Any other problem within the system checks out problem-free
- Initial communication from the primary thermostat never turns up at the main board
