Carrier 50JZ030310 Ignition Control Board
The purpose of the ignition control board is that it regulates gas intake, the ignition timing as well as other safety devices. It has been a very important device that, over the years, has merged to become a major component of the main board instead of a separate board.
Clues your main ignition board will have to be replaced
