Carrier 58MCB040 Ignition Control Board
Another safety feature is the ignition control board, which controls the main gas intake valve, the ignition timing and a few other devices. It has always been a vital electronic safety board that has now become a part of the main control board instead of a separate board.
Major signs of an unhealthy ignition board
- The ignition system refuses to launch when it is supposed to
- Any other problem throughout the system checks out good
- Initial communication from the thermostat never turns up at the control board
