Mitsubishi MSZ-FA25VA Control Board
Your furnace or AC will not activate without this vital piece of hardware is installed as it should be according to the manufacturer. The Mitsubishi MSZ-FA25VA control board is made to control everything including the gas valve, the ignition igniter, all the sensors as well as the air circulator all together. Any control board you choose will have a part number that will match the brand and the model of the unit in question. You must be sure while choosing a new control board because of the many variances of models within certain brands.
Some clues to watch for in a failing primary control board
- System ceases to run properly
- When turned on, there is some sort of error code lit up on the board
- Power to the control board has to be turned off and back on many times a day in order to operate
