International Comfort Products H9MPD100J20C2 Ignition Control Board
The purpose of the ignition control board is that it checks out gas intake, the igniter and a few other devices. It has been a very important electronic safety board that, in most cases, has become a piece of the main circuit board instead of having two separate boards.
What are the clues to watch out for to know my main ignition board is about to go out?
- Initial communication from the remote thermostat does not get to the International Comfort Products control board
- The ignition system fails to initiate even when the thermostat kicks it on
- Every other device attached to the system is explored and ends up being fine
