Payne PG8JAA042090AAJA Ignition Control Board
The main ignition control board governs the main gas intake valve, the igniter and some more sensing equipment. The ignition control board was always an important safety device that is usually a piece of the main circuit board instead of its own individual board.
Subtle cues of an unhealthy ignition control board
- Signal from main thermostat does not make it to the Payne control board
- The primary ignition sequence is unable to fire up even when called upon
- Any other potential problem in the HVAC system checked out to be good
