Carrier 48GX030060300 Ignition Control Board
The main ignition control board checks out gas flow, the ignition sequence and a few other devices. The ignition control board was always an important safety feature that, over the years, has merged to become a piece of the main circuit board for enhanced safety.
Major indications your main ignition board needs a replacement ASAP
- Initial communication from the thermostat gets lost before it makes it to the Carrier control board
- Ignition sequence refuses to commence then the thermostat send a signal
- Any other problem within the system is explored and ends up being a-OK
