Friedrich MW30C3G Ignition Control Board
An ignition control board controls gas intake, the ignition timing and other important devices. The ignition control board was always an important circuit board that is usually a part of the main control board instead of its own individual board.
What signals that my ignition board is crapping out?
- Initial communication from the main thermostat does not turn up at the main control board
- HVAC ignition system does not commence when called upon
- Any other potential problem attached to the system checks out okay
