I have a Mitubishi AC unit model MS15NN (ductless type) that has be diagnosed with a bad circuit board. I can't seem to locat this board, does anyone know where I can find this. They don't make this unit anymore. P/N for the board is E02 271 450 I've been to the factory. Even a refurbished unit would be OK. My name is Michael and my email is [email protected] my phone is 757-620-2850

If you have been to the factory and they can not locate one for you, it will be very time consuming to locate a replacement board. You will need to contact local hvac companys and see if they can locate one for you. Mitubishi has an extremely complex control board, many times more than one per unit. If you can not find an exact replacement, you are pretty much out of luck. Sorry. Who diagnosed the control board? Who ever diagnosed it should have the resources to find a replacement. If they cant, I would guess they may not now how to properly diagnose the board. Just an educated guess.
