I think what you are seeing is the NO CO code. On your model the LED display will show n making that n with 3 straight lines. If so, that is why the NEW board showed the same code. You have an operational problem and the refer is throwing that code to prevent operation of the refer. When you get the NO CO, you turn the refer OFF for 10 seconds and restart.
