Carrier 48XZ048090300 Ignition Control Board
Another safety feature is the ignition control board, which oversees the main gas intake valve, the ignition sequence and all the flame sensing devices. It has been a very important safety feature that some manufacturers have decided to blend to be a major component of the main board instead of having two separate boards.
Simple warnings that your chief ignition control board is not working properly?
- Everything else connected to the system checks out just fine
- Ignition system is unable to fire up even though it is supposed to
- The initial signal from the remote thermostat never turns up at the Carrier control board
