Mitsubishi MSZ-A12NA Control Board
The Mitsubishi MSZ-A12NA control board is made to command everything including the gas valve, the igniter, all the sensors as well as the blower all at once. HVAC systems will not run unless this board is properly connected to the unit. A matching board must be compatible with both the brand and model of the system you have installed. Be absolutely sure upon choosing a board as a replacement due to so many small differences in particular brands and their models.
Symptoms of a faulty primary control board
- There may be a certain error code being shown on the board
- System is unwilling to function whatsoever
- The entire system needs to be reset quite often for the heating or cooling to kick in
