Mitsubishi MSY-GE12NA Control Board
The Mitsubishi MSY-GE12NA control board is constructed to regulate the gas valve, the igniter, all the various sensors as well as the air circulator all at once. The entire heating and cooling system will not activate lest this board is in place and connected. Any control board you choose will have a matching part number that will fit in both the brand and model of HVAC system. Be very careful while choosing a new control board due to the vast differences in particular brands and their models.
Major warnings your Mitsubishi control board is going out
- The unit ceases to go at all
- There seems to be a certain error code showing up somewhere on the circuit board
- Power to the circuit board has to be powered down and back up many times a week for it to run
