International Comfort Products H8DNL100F14A1 Ignition Control Board
The ignition control board is a safety device that controls gas intake, the ignition ignitor and other important devices. It is an important electronic circuit board that is usually a piece of the main circuit board instead of having two separate boards.
What warnings are present when my main ignition board is about to go out?
- HVAC ignition system refuses to initiate at all
- Signal from primary thermostat does not show up at the main control board
- Any other device throughout the system is inspected and seems to be okay
