    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.

Kitchenaid KMHS120ESS4 Microwave hood light won't turn off

Our vent hood light was out (or so we thought). I went to unscrew it (not realizing you should unplug the whole unit first) and it lit back up... so I screwed it back in. A few seconds later, it popped/shattered. I then replaced the bulb and now it stays on bright even when you cycle through the low, high, and off switch settings.
I have a new control board on the way, but after a little research elsewhere... I'm wondering if I can't repair the existing circuit board myself. Looks like from the wiring diagram for our model that a TRIAC on the hood lamp circuit is the likely culprit? I opened up our panel to get a look at the existing TRIAC and ordered a replacement BT136-600D that should arrive tomorrow or next day.

Does this sound like a logical step/solution?

Thanks for any help/advice/direction.
