International Comfort Products NDN5100BFA1 Ignition Control Board
The main ignition control board controls gas flow, the ignition timing as well as other safety devices. It is an important board that, over the years, has merged to become a part of the main control board instead of a separate board.
Symptoms of a dying ignition board
- Every other device within the furnace checked out to be in good condition
- The initial signal from the thermostat gets lost before it makes it to the main board
- HVAC ignition cycle will not begin at all
