International Comfort Products PGC018K040F Ignition Control Board
The main reason to have an ignition control board is that it controls the main gas intake valve, the ignition sequence and the flame sensing circuits. It has been a very important electronic safety board that has now become a part of the main control board instead of a separate board.
Signs your main ignition board has to be replaced
- The initial signal from the main thermostat does not get to the main control board
- Initial ignition sequence fails to kick in even though it is supposed to
- Any other device within the furnace is explored and ends up being all right
