International Comfort Products T9MPT050F12A1 Ignition Control Board
The main reason to have an ignition control board is that it oversees the main gas intake valve, the ignition ignitor and a few other devices. It has always been a vital electronic safety board that some manufacturers have decided to blend to be a piece of the main circuit board instead of having two separate boards.
How do you know if your main ignition board has a need to be replaced?
- Every other problem attached to the system is explored and ends up being okay
- Initial ignition sequence declines to launch when it receives a proper signal
- The on-signal from the home thermostat gets lost before it makes it to the control board
