The purpose of the ignition control board is that it oversees the main gas intake valve, the ignition sequence and other safety devices built into the system. The ignition control board was always an important board that is usually a vital part of the main control board for safety reasons.
Main clues your ignition control board will have to be replaced

- Communication from the main thermostat gets lost before it makes it to the Carrier control board
- The ignition system refuses to kick in even when called upon
