Is the Uwave a separate unit or built-in? Do you have a voltmeter and any experience using it? There is probably a schematic somewhere on the inside covering metal. Whenever you do anything, unplag from the wall supply and use a clip lead to short out the two capacitor terminals. After you short out the capacitor, wait for 4 or 5 seconds and short it out again, just to kill any residual voltage that can build up on that type of capacitor.

There are lots of places to get info on Uwave ovens on the internet, just do what I said above and you should be safe. Also, it never hurts to have a second person in the room when you are working for safety's sake, just don't let them talk and distract you!
