International Comfort Products H9MPD050F12A1 Ignition Control Board
The purpose of the ignition control board is that it checks the main gas intake valve, the ignition sequence and some other sensors. It has always been a vital safety feature that has now become a major component of the main board instead of its own individual board.
Clues to watch for to know the chief ignition control board has very little life left
- The main ignition cycle refuses to fire up when called upon
- Every other problem in the heating and cooling system is looked at and turns out to be in fine condition
- Communication from the home thermostat never makes it to the International Comfort Products control board
