Carrier 48GX024040300 Ignition Control Board
The main ignition control board has control over the natural gas, the ignition timing and a few other devices. The ignition control board was always an important circuit board that, over the years, has merged to become a major component of the main board instead of its own individual board.
Major clues your ignition control board needs to be replaced
- Signal from primary thermostat never moves to the control board
- Every other thing within the heating and AC system is inspected and seems to be flawless
- The ignition cycle is unable to commence at all
