The main ignition control board oversees the natural gas, the ignition sequence and a few other devices. It is an important board that some manufacturers have decided to blend to be a standard part of the main board instead of its own individual board.
Major warnings your ignition control board is not going to last much longer
- Heating and cooling system does not fire up when it is supposed to
- Signal from main thermostat never does reach the main control board
- Every other device attached to the system is inspected and turns out to be in good health
