International Comfort Products GPFM48K080F Ignition Control Board
The main ignition control board governs the main gas intake valve, the ignition sequence and a few other devices. It has always been a vital circuit board that, over the years, has merged to become a vital part of the main control board instead of its own individual board.
What warnings should I watch out for to know if my ignition board is almost dead?
- Initial communication from the remote thermostat never gets to the control board
- Every other problem in the HVAC system checked out to be in good health
- The main ignition cycle is unwilling to begin when called upon
