International Comfort Products GPFM36L080F Ignition Control Board
An ignition control board keeps an eye on gas flow, the ignition timing and some more sensing equipment. The ignition control board was always an important safety device that some companies have moved to be a piece of the main circuit board for the sake of being more efficient.
General warnings to watch for in a failing main ignition board
- Every other device within the heating and AC system is inspected and seems to be a-OK
- Communication from the remote thermostat gets lost before it makes it to the control board
- The primary ignition sequence refuses to begin even when the thermostat kicks it on
