Carrier 48GS Ignition Control Board
The main ignition control board controls gas intake, the ignition sequence and a few other devices. It has been a very important electronic safety board that has now become a vital part of the main control board in order to have better control over the system.
What signals that my ignition control board is about to go out?
- Every other potential issue in the HVAC system is researched and comes to be problem-free
- The primary ignition sequence does not fire up at all
- Initial communication from the thermostat does not show up at the main control board
