Question about Microwave Ovens
Do not know how to access internal fuse to check/change. Nor how to change either control or display panel. Does microwave have to be taken down to access any or all of these parts, please?

Most likely a shorted capacitor is causing the fuse to blow. Easy and cheap to fix.

no the control does not come off from behind.
what you will find is the top vent grill has to come off first. it has 2 phillips screws that hold it to the top of your unit.
you will find 4 screws on the top, go ahead and take all 4 out and then pull the grill out from the top and hinge outward to remove/ once the grill is off, then there is 1 more phillips screw that holds the control board/ touch panel to the frame. remove and then lift up then out on the panel.
now that you are into the unit, make sure you have UNPLUGGED it first. the fuse is about 1 1/4 inch long white ceramic material with metal ends. you can find a new one at a radio shack or get one online for your unit. r/s has them for cheap and if that allows the unit to run again, great, but...
there was something that caused the fuse to go bad. so dont be surprised if you need a diode or capacitor to fix why the fuse went bad.

your fuse will be located somewhere close to where the power cord comes in. It's not a regular glass fuse it looks like ceramic with the silver looking ends that's your fuse

You have to replace the control board. Sharp has had problems with the display boards for awhile. There is no bulb or fuse you can change.

Is it dead, meaning no
display, no light when you open the door and no beeps when you press a
pad on the keypad?

I would suspect the 20A ceramic line fuse or the magnetron temperature fuse.
