Mitsubishi MS-A09WA-1 Control Board
The control board is made to command everything including the gas valve, the igniter, most sensors as well as the blower all in one unit. Most systems will not function without this vital piece of hardware is properly connected to the unit. The brand of board you choose will have a part number that will match both the brand and model of your heating and cooling system. You must do some research upon picking a replacement board due to so many small differences in models and types.
Signals to watch for in a bad main circuit board
- The power to the system has to be turned off and back on many times a week for the furnace or AC to kick on
- When turned on, there is a strange code shown directly on the board
- AC unit or heating unit declines to do anything whatsoever
