International Comfort Products PYPA36GA1 Ignition Control Board
The purpose of the ignition control board is that it governs gas intake, the ignition sequence as well as other safety devices. The ignition control board was always an important safety device that has now become a piece of the main circuit board instead of having two separate boards.
Subtle hints the ignition board will die soon
- Initial communication from the main thermostat never gets to the control board
- The primary ignition sequence will not kick in even when the thermostat kicks it on
- Any other potential problem within the furnace is explored and ends up being OK
