The fuse is usually a 250V 15 or 20 AMP and can be found at any hardware store. As for those screws...those are special tamper proof screws made to keep the average consumer out of dangerous appliances. There's about 4000 volts inside a microwave oven when it is energized. That's why the manufacturers don't want the average Joe tampering with it. You can, however, buy the tool required to get inside the unit for a reasonable price. I think it's less than $30 and I know Craftsman makes it. The line fuse is located on or near the input line filter board. Just follow the input power cord and you will find it. Just keep in mind, that if the fuse is blown, it usually blows for a reason. You may have other problems. Let me know if this helps you.

Is it like this?
If so, there are several ways to loosen them:
Some folks just use a hammer to tap and loosen the screw, then a "star", t-type, or small flathead screwdriver can be used to remove the screw.
Sometimes the screws are tough, so you may only be able to just bend the post slightly with a punch, then a small flat blade will "grab" enough to turn the screw. Pliers on the handle will help, too.
Another creative solution is to use a hacksaw or a Dremel tool to carefully cut a slot in the head so a flatblade will fit it, as shown in the photo below:

The Panasonic NN-S960WA (may be identical) has the fuse at back, right, on top, & inside the cover. The screws are tamper proof screws. You can create a slot in the heads (2 screws) with a hacksaw blade and open with a flat blade screw driver. Don't forget to unplug the unit first.

it is just behind the front top grill on the right. The plastic grill that goes accross the entire top of the front of the unit. Then behind it on the right is a small power board that has the ceramic fuse on it.
remove 2 srews from top of microwave that hold the top of this plastic grill in place.
Then slide the grill to the left or right (I don't remember which way). Now the grill will come out.
The fuse is usually the secondary issue. Most often, it is the cavity TCO that goes out. This is the thermo-coupler that breaks the main power circuit if the inside of the mocrowave gets over 100 degrees C. requires taking the unit down and taking the cover off.

under the outer cover,its either a 10-15-or 20 amp ceramic safety fuse avail at most hardware stores, the amp rating is on the side of the fuse, if the new one blows then either the H.V. diode/capacitor or the magnetron can be suspects
