Goodman ACVC90905DXAB Ignition Control Board
The main ignition control board oversees the gas valve, the ignition sequence and all the flame sensing devices. The ignition control board was always an important safety feature that, over the years, has merged to become a major component of the main board instead of its own individual board.
What warnings are present when my major ignition board is in need of replacing?
- The on-signal from the home thermostat does not reach the main control board
- Any other device connected to the system checks out just fine
- Ignition sequence can not commence even when called upon
