International Comfort Products GPFM36S100F Ignition Control Board
The main reason to have an ignition control board is that it controls the natural gas, the ignition ignitor and other safety devices built into the system. The ignition control board was always an important safety device that some manufacturers have decided to blend to be a vital part of the main control board for enhanced safety.
Major warnings of a faulty ignition control board
- Initial communication from the thermostat never makes it to the main control board
