Carrier 48GS018040300 Ignition Control Board
The main reason to have an ignition control board is that it has control over gas flow, the ignition timing and the flame sensing circuits. It has been a very important safety feature that is usually a major component of the main board instead of its own individual board.
How do you know if your Carrier ignition control board needs replacing?
- Ignition cycle refuses to kick in even when the thermostat kicks it on
- Any other device throughout the system checked out to be all right
- Communication from the remote thermostat never makes contact with the main board
