International Comfort Products GDJ050M12A1 Ignition Control Board
The purpose of the ignition control board is that it has control over the gas valve, the ignition timing and a few other devices. It is an important device that, in most cases, has become a vital part of the main control board instead of its own individual board.
Clues to watch for to know the ignition board is failing
- Communication from the main thermostat does not make it to the main control board
- The primary ignition sequence can not launch when called upon
- Any other problem attached to the system checked out to be in fine condition
