International Comfort Products NNE100F20G1 Ignition Control Board
The main ignition control board has control over the main gas intake valve, the ignition sequence and other important devices. It has always been a vital electronic safety board that is now usually a part of the main control board instead of a separate board.
Some warnings poorly running main ignition board
- Initial communication from the remote thermostat does not reach the International Comfort Products control board
- Every other thing attached to the system is looked at and turns out to be swell
- The ignition cycle declines to activate when it receives a proper signal
