Another safety feature is the ignition control board, which oversees gas flow, the ignition timing and the flame sensing circuits.

What warnings are present when my ignition control board is failing?
- Ignition sequence refuses to launch at all
- Communication from the main thermostat does not reach the main control board
- Everything else within the furnace is inspected and turns out to be okay
