    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.

Oster microwave Replacing HV capacitor

I've got an Oster microwave I'm trying to bring back to life (it was abandoned). I'm pretty sure I've narrowed it down to the high voltage capacitor, I should have access to some better testing equipment tomorrow to make sure. I've found some HV capacitors, but they aren't an exact replacement to what's currently in the unit. The current capacitor is 2200v 1.0uF +/- 3%, how important is it that this is an exact match? Would a 2100v 1.05uF capacitor be fine?
