International Comfort Products H9MPT100J16A1 Ignition Control Board
The main ignition control board keeps an eye on the gas valve, the ignition sequence and the flame sensing circuits. It is an important board that has now become a major component of the main board instead of its own individual board.
Important clues of a weakening main ignition board
- Heating and cooling system will not fire up even when called upon
- Any other device in the HVAC system is inspected and turns out to be swell
- Initial communication from the remote thermostat never reaches the main board
