Friedrich MW09Y3FM Ignition Control Board
The main ignition control board checks gas flow, the ignition ignitor and other safety devices built into the system. The ignition control board was always an important safety device that, in most cases, has become a vital part of the main control board instead of its own individual board.
Easy warnings of a faulty Friedrich ignition control board
- Initial ignition sequence refuses to commence when it is supposed to
- Any other device in the heating and cooling system checks out just fine
- The on-signal from the thermostat does not get to the main control board
