Microwave would not start when door closed. Sometimes you could push in or jiggle door and it would work for awhile and then it woud stop again. I knew it eas a door switch issue but wasn't certain which of the 3 or the body latch itself.
I removed the body latch assembly and found the bottom micro switch (NC) terminal burnt and loose. I replaced and working perfectly fine now. Easy diagnose and easy repair.

The microwave would not turn on or would run with the door open
Other tools that are usefull long needle nose pliers, long thin blade screw driver and small magnetic flashlight. Place the microwave on a work bench and remove the case it cover 3 sides. Place the microwave on a chair so it can stand with the controls up. You are replacing the lower door microswitch. The switch is located behind the control panel in the lower part of the area. The switch is several inches inside this area and your hands will not fit. Take care when moving wires and a couple of sensors. Use the thin blade screwdriver to release a tab holding the switch in place. Do not break this tab. Take the needle nose pliers and remove the switch. Put the wires on the new switch, open the door a short distance so a door lever moves enough to put the microswitch back into the bracket.
