International Comfort Products PGAA30D1K1 Ignition Control Board
The main ignition control board may control gas flow, the ignition timing and a few other devices. It has always been a vital electronic circuit board that, over the years, has merged to become a standard part of the main board instead of its own individual board.
Major indications of a bad main ignition board
- HVAC ignition system refuses to activate even when called upon
- Every other problem throughout the system is inspected and turns out to be acceptable
- Communication from the home thermostat does not reach the main control board
