International Comfort Products H8MPN100F14B1 Ignition Control Board
Another safety feature is the ignition control board, which regulates gas intake, the ignition sequence and the flame sensing circuits. The ignition control board was always an important electronic safety board that has now become a major component of the main board instead of having two separate boards.
What to see if the major ignition board is crapping out?
- Any other device attached to the system is inspected and seems to be all right
- The on-signal from the thermostat never does reach the main board
- Ignition cycle will not start when it receives a proper signal
