International Comfort Products GNK050N12A3 Ignition Control Board
The main ignition control board checks the natural gas, the igniter and all the flame sensing devices. It has always been a vital circuit board that, in most cases, has become a standard part of the main board instead of a separate board.
Elements of a weakening major ignition board
- Any other device within the system is looked at and turns out to be all right
- Communication from the home thermostat never does reach the control board
- The ignition system fails to launch when called upon
