International Comfort Products NAC218GKA1 Ignition Control Board
The main ignition control board checks out gas intake, the ignition timing and some more sensing equipment. It has always been a vital safety device that is usually a standard part of the main board instead of having two separate boards.
Easy warnings the ignition board will need replacing
- The on-signal from the main thermostat never moves to the main control board
- Ignition cycle will not begin when it is supposed to
- Any other problem in the HVAC system is explored and ends up being okay
