Mitsubishi MSZ-09UN Control Board
Heating and cooling systems will not even be able to function lest the circuit board is in connected and operational. The Mitsubishi MSZ-09UN control board is created to command the gas valve, the igniter, most sensors as well as the blower all together. You must do some research when choosing a control board due to so many small differences in HVAC systems. A control board that you have chosen will have a part number that will match the brand and the model of the unit in question.
General indicators that your main board is in need of replacing
- Entire unit is unwilling to work properly
- The system board has to be turned off and back on more often than not for the furnace or AC to kick on
- There seems to be a certain error code indicated directly somewhere on the circuit board
