Whynter ARC-143MX Ignition Control Board
An ignition control board may control gas intake, the ignition timing and a few other devices. It is an important electronic safety board that, in most cases, has become a major component of the main board instead of a separate board.
Hints the chief ignition control board should be replaced
- Every other potential issue in the heating and cooling system is inspected and turns out to be acceptable
- Initial sequence refuses to begin when it is supposed to
- Signal from main thermostat never turns up at the Whynter control board
