    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.

Sears Kenmore

Older wall microwave. (20~ years)
When running strange buzz with smell that smells "electronic"
Stopped it immediately when I heard the buzz. Doesn't sound like
a normal microwave buzz.
Sounds slightly higher pitch.

Will appreciate ideas

Thanks

Could be the HV diode. Check it with a meter. It should be open in one direction and closed when you reverse the test leads. Did it stop working/heating?
