The ignition control board is a safety device that regulates the gas valve, the ignition sequence and some other sensors. The ignition control board was always an important circuit board that, over the years, has merged to become a piece of the main circuit board for the sake of being more efficient.
Some warnings the chief ignition control board needs replacing
- Heating and cooling system can not initiate then the thermostat send a signal
- Everything else within the furnace checked out to be good
- The on-signal from the remote thermostat never makes it to the main control board
