tamper proof hex bit size?
My Dacor DCM Microwave/convection does not turn or heat altough the fan runs and panel seems to work. I was removing the screws on the back in order to lift off the top/sides but can't find a tamper proof bit that fits the Dacor tamper proof screws. Is there a part number and sorce to purchase the required part or should I just break them off? The unit is out od warranty.

It's a a T20H Torx type or GTXH20-100, available from hardware stores, or places like Lowe's or Wal-Mart.
Some folks just break or bend the post in the middle, then insert a small flat head jeweler's screwdriver in the space between the post & outer edge of the hole. A sharp tap with a hammer will loosen them a bit.
Otherwise, you can use a hacksaw or Dremel tool to cut a groove in them, then use a flat head screwdriver to remove them.
Just be sure that any special grounding screws get put back where they were to ensure proper grounding of the case, an important protection from shock hazard in rare cases of internal wiring breakage.
The Dacor DCM24 is essentially a rebranded Sharp R930A and I have the full service manual here at my site.
As to what's wrong with it, I would say your secondary interlock (bottom door switch) has failed.
The service manual will cover it, but there's additional info here: http://www.microwavedisplay.com/doorsw.txt
The best place to order Sharp parts is Tritronics.
