International Comfort Products T9MPD080J16A2 Ignition Control Board
The main ignition control board controls the main gas intake valve, the ignition timing and some other sensors. It is an important electronic circuit board that has now become a vital part of the main control board instead of a separate board.
Major clues of a faulty major ignition board
- Signal from main thermostat never gets to the International Comfort Products control board
- Initial ignition sequence is unable to start even though it is supposed to
- Every other device throughout the system is looked at and turns out to be all right
