International Comfort Products NTN3075FBA1 Ignition Control Board
The ignition control board is a safety device that keeps an eye on the gas valve, the ignition timing and some more sensing equipment. It has always been a vital circuit board that is usually a major component of the main board instead of having two separate boards.
Clues the major ignition board is going out
- Initial communication from the thermostat never makes contact with the International Comfort Products control board
- Initial sequence is unwilling to begin then the thermostat send a signal
- Every other thing within the furnace is inspected and seems to be all right
