Any repair on any electrical appliance should be done with the plug removed from the power socket. Microwave ovens are dangerous and has been known to kill people. Rather be safe than sorry. If a fuse is suspected, make sure to unplug first. It should be discharged as it can, even after switching off, cause a very nasty shock.

When you close the oven door the latches operate a couple of interlock switches that control power. It may be that one of the door switches is bad or out of adjustment. It's also possible that one of the door latches is broken so it's not hitting the switch. There should be two door latches. Are they both there? This oven could be fixed by adjusting or replacing the interlock parts as needed. Because of concerns about microwave leakage from an improper door seal, you should have this oven serviced by a professional.

This
is a problem in one of the damper-related components, either the switch
or motor or the damper door may be binding.
The
damper is a door inside that opens or closes depending on cooking mode.
If the controller senses that the door is not in the right position, it
will shut down the cook cycle.
Sharp models stop after
59 seconds.
See the attached sample
drawing for a typical damper assembly.
We have the applicable
service manuals for these models and have uploaded it to our site here and here to help you.
If a switch is all you
need, we offer a universal type for only $5 postpaid which you can
order here.

There are a couple of safety thermostats in the oven to shut down power if something overheats. One is on the magnetron tube (the microwave source), the other is on the cooking cavity. These sometimes go bad. There's also a power line fuse that may have failed, or become loose in its mounting clips. These can be tested with an ohmmeter; they should all measure very close to zero ohms if they're good.
Another possibility is that the control circuit board in the oven may have failed. I have worked on several Sharp ovens where the power transformer for the board has gone bad for no good reason. If the board goes bad the oven may appear to be dead as well.
Microwave servicing is best left to professionals. If you're thinking of keeping this one, take it to a service shop (or call for home service) and get an estimate. Then decide whether to repair or replace.
Hope this has helped a little. Thanks for using Fixya!

SOURCE: how do i remove sharp microwave from wall model
The only problem that ricksterboy doesn't list, is there are also two screws located underneath as well. You have to take off the filter screens to find them. They secure into steel supports inside the microwave.
No getting the micro off the wall w/o removing them, or using a sledge hammer...which after all the time we used trying to get the thing off the wall, seemed like a good theraputic option.
Lucky we took off the vent cover and discovered the additional anchors.
Good luck!
