International Comfort Products NAC230GKA1 Ignition Control Board
An ignition control board oversees the main gas intake valve, the ignition ignitor and other safety devices built into the system. The ignition control board was always an important circuit board that has now become a part of the main control board for enhanced safety.
Major signs your main ignition board needs replacing
- Every other potential issue connected to the system is inspected and turns out to be OK
- Signal from main thermostat never makes contact with the main control board
- The main ignition cycle is unwilling to fire up even when the thermostat kicks it on
