International Comfort Products NDN5100BHC2 Ignition Control Board
An ignition control board has control over the main gas intake valve, the ignition timing and some other sensors. The ignition control board was always an important device that some manufacturers have decided to blend to be a piece of the main circuit board instead of its own individual board.
Major warnings the ignition board is not going to last much longer
- The main ignition cycle is unable to fire up when called upon
- The initial signal from the thermostat never does reach the main control board
- Every other thing throughout the system is looked at and turns out to be in good health
