International Comfort Products H8MPN100F20B1 Ignition Control Board
An ignition control board controls the main gas intake valve, the ignition timing and a few other devices. It has always been a vital safety device that some companies have moved to be a piece of the main circuit board in order to have better control over the system.
Major symptoms of a barely functioning ignition control board
- The on-signal from the primary thermostat does not show up at the main control board
- Initial sequence does not launch no matter what
- Any other potential problem within the system checks out in good health
