Bryant 330JAV Ignition Control Board
The ignition control board is a safety device that may control gas intake, the ignition sequence and some more sensing equipment. It has been a very important safety feature that, in most cases, has become a vital part of the main control board instead of a separate board.
Major indications of a dying ignition control board
- Every other potential issue connected to the system checks out okay
- Initial sequence can not fire up even when the thermostat kicks it on
- The electrical signal from the primary thermostat never makes it to the main control board
