International Comfort Products GNL075N12C3 Ignition Control Board
The main ignition control board may control the gas valve, the ignition timing and some more sensing equipment. The ignition control board was always an important board that is now usually a vital part of the main control board in order to have better control over the system.
How do you know if your ignition board has to be replaced?
- The primary ignition sequence will not launch then the thermostat send a signal
- Initial communication from the home thermostat does not reach the main control board
- Any other problem in the heating and cooling system checked out to be flawless
