International Comfort Products NTGM100EHA3 Ignition Control Board
An ignition control board checks out gas flow, the ignition sequence and other safety devices built into the system. The ignition control board was always an important electronic circuit board that some companies have moved to be a major component of the main board for safety reasons.
Warnings the ignition board has little life left
- The initial signal from the primary thermostat never makes it to the main board
- HVAC ignition cycle declines to commence even when the thermostat kicks it on
- Every other thing connected to the system is inspected and turns out to be problem-free
