The microwave magnet would start when the door closed w/o a keypad signal.
Unplugged the microvave, removed the phillips screw holding the right hand section of the microwave in place (Note: This screw is found by looking through a vent opening in the TOP of the microwave body.). Lifted up and out on the right hand section of the microwave. At this point the right hand section is completely unattached to the microwave body. Unplugged all of the polarized wiring harnesses and removed the screw holding the green wire to the board holder. Removed the screws holding the board to the right hand section and installed the new board. Reversed the procedure to put the microwave back together. Note: Look at and manipulate the keypad ribbon recepticle on the new board to see how to remove and reattach the ribbon, if needed.

I accidently shorted my light socket removing the bulb under my unit. There was a pop. My entire microwave still works, but the light has no power coming down to the light socket.

I turned the underside light on and there was a flash and the light had burnt out, after replacing the bulb the light will not turn off even after pressig the light button. The button appears to work, I get a tone everytime I press the light button and it also cycles thru high, low and the off setting but the light still stays on. I am at a loss
