International Comfort Products NDN5100BHC1 Ignition Control Board
Another safety feature is the ignition control board, which manages the natural gas, the igniter and all the flame sensing devices. It is an important board that, over the years, has merged to become a piece of the main circuit board instead of having two separate boards.
How can I tell if my ignition board is about to stop working?
- Communication from the thermostat never gets to the main control board
- Every other thing in the heating and cooling system is looked at and turns out to be okay
- Ignition sequence fails to begin even when the thermostat kicks it on
