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.
