• ** REMEMBER! **The microwave can still shock you even unplugged!!

    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.

The unit is completely dead. It was running when the power quit. No noise. Ther outlet is powered and the unit was unplugged then replugged. I suspect a thermal fuse but do not know how to access it. Thanks

You should be able to access the fuse behind the control panel. There's probably only one screw on top but you might have to remove the grill first. If the fuse is blown, you'll need to use a meter and check the door switches for continuity. Always disconnect at least one wire from the switch you're testing. Always unplug the microwave and discharge the high voltage capacitor before doing any service on electrical components.
