International Comfort Products NNE100J20A1 Ignition Control Board
The main ignition control board checks the gas valve, the ignition sequence as well as other safety devices. It is an important device that is now usually a vital part of the main control board for the sake of being more efficient.
Key symptoms to watch for in a bad main ignition board
- Every other thing within the heating and AC system is looked at and turns out to be in good health
- The primary ignition sequence declines to start when it is supposed to
- Initial communication from the main thermostat never makes contact with the main board
