International Comfort Products FBF050B12A1 Ignition Control Board
The purpose of the ignition control board is that it may control the gas valve, the ignition sequence and other important devices. The ignition control board was always an important safety device that is now usually a part of the main control board for enhanced safety.
Some clues the major ignition board needs replacing
- The ignition cycle refuses to commence when it receives a proper signal
- Every other problem within the furnace checks out in good health
- The initial signal from the main thermostat does not get to the main board
