Carrier 58MXB120F10120 Ignition Control Board
Another safety feature is the ignition control board, which has control over gas intake, the ignition timing and other safety devices built into the system. It has been a very important safety feature that, over the years, has merged to become a piece of the main circuit board instead of its own individual board.
Major warnings of a defective Carrier ignition control board
- Ignition cycle is unwilling to fire up at all
- Every other potential issue in the system is looked at and turns out to be acceptable
