Mitsubishi MSY-A15NA Ignition Control Board
The main ignition control board governs gas intake, the ignition ignitor and other important devices. It has been a very important board that, in most cases, has become a standard part of the main board instead of having two separate boards.
What warnings should I watch out for to know if my chief ignition control board is failing?
- Every other problem within the system checked out to be fine
- Ignition sequence can not start at all
- The electrical signal from the thermostat never makes it to the Mitsubishi control board
