International Comfort Products GDL100N16A3 Ignition Control Board
The main reason to have an ignition control board is that it checks gas flow, the ignition ignitor and other safety devices built into the system. The ignition control board was always an important circuit board that, in most cases, has become a vital part of the main control board for enhanced safety.
Key clues of a weakening ignition control board
