International Comfort Products C8DNL050B12A1 Ignition Control Board
An ignition control board regulates gas intake, the igniter as well as other safety devices. The ignition control board was always an important device that, over the years, has merged to become a standard part of the main board instead of a separate board.
Major indications of a laboring ignition board
- Signal from main thermostat never reaches the main control board
- The ignition cycle is unwilling to launch even when called upon
- Every other device in the HVAC system checked out to be OK
