International Comfort Products H8MPL125J20A1 Ignition Control Board
The main reason to have an ignition control board is that it keeps an eye on the natural gas, the ignition ignitor and a few other devices. It is an important circuit board that some manufacturers have decided to blend to be a part of the main control board instead of a separate board.

- Signal from home thermostat does not show up at the main control board
- Heating and cooling system is unwilling to start even when the thermostat kicks it on
