    ALWAYS discharge the high-voltage capacitor first if you even think your hands will come close to any HIGH VOLTAGE components.

    Jeff mentions this: Anything in the high voltage ( magnetron, capacitor, diode, wires to and from ):
    ...Use a metal ( not the shiny chrome type ) screw driver with a insulated handle to short across ( touch both at the same time ) the terminals of the high voltage capacitor to discharge it.

We have had this Panasonic microwave (model NNSN561W) for about 4 years. For the most part we are satisfied with it, however it has always had a door closing problem, specifically, it is hard to close. The spring feels too tight. Most of the people in the house have adopted the habit of slamming the door to get it closed. Besides that, it is also difficult to OPEN the door, again because something feels too tight. Sometimes, pushing the door release shoves the unit across the counter--one has to hold it down to keep it in place in order to push hard enough to open it. It's been an irritation from the first use. I had hoped it would loosen up in time. However recently the microwave has stopped working, so I examined it and found a faulty door switch. I replaced the door switch but I am convinced that the failure of the switch was at least partly caused by the habitual slamming of the door. So I decided to try to loosen the spring. I also slightly modified the latch hook arm surfaces to make it easier for the latch mechanism to operate when closing the door. Instructions for testing and replacing door switches can be found elsewhere so I am not documenting that straightforward procedure. But here are some illustrations of what I did to modify the spring and latch hook arms.
