looking for a service manual to repair door switch?

power off, then remove the lid, provided the old door switch wiring is still in place you make a note of wire positions (paper or camera picture is good )
unscrew the 2 front inter lock screws then remove the wiring,
you then just replace the wires on to the new switch using your drawing or photo on to the new switch then screw the new switch back to the cabinet refit the lid
