If it went dead almost immediately after pressing the Start pad, that\'s usually a shorted high-voltage capacitor.
If it went dead a few seconds after pressing the Start pad, that\'s usually a failing high-voltage transformer.
Here are some links you or a friend can use for test help, but read their safety warnings first:
You can probably find an exploded view by entering your FULL model number here: http://www3.sears.com (the 3 is correct)
You can order Sharp parts from Sears or from Tritronics at http://www.wehaveparts.com

You may have a sticky door switch. Try a simple "slamming" of the door, don't over do it, just a little harder than normal. This may help pop the plunger in the switch back up. The switch could have also become loose and moved out of its adjustment.
If this does not help, a technician should save you time and money with this sometimes perplexing problem.

I have over 20 years experience with microwaves and over 25 with all other electronics, and I'll have to say it sounds to me also like some kind of power surge "scrambling" its "brains".
Or possibly its power is being interrupted for a fraction of a second and having the same effect.
A microwave should really be on its own circuit breaker.
Microwave ovens, refrigerators, toasters, and electric ovens are very high current devices.
There are power line (mains) surges created when they cycle on and off.
If the microwave can't be on its own breaker, then maybe you can try a power strip with a surge suppressor, or better yet, a power strip with a surge suppressor and a built-in noise filter.
Or it may be that there is a subtle bad connection on the circuit board or at the fuse holder.
These kinds of problems are difficult to diagnose, and even harder to do remotely. Especially since I'm in the US! *grin*
I would strongly suggest that if you can't cure this with a surge strip or similar, please carefully document when and how it fails, then while it is in a failed state, open the door (to keep it from starting on its own) and call Sharp customer service at 1300 13 50 22.
Or you could visit here and click on Service Centre Location search.
You should have a one year warranty, so you should get in touch with a Sharp-authorized repair center.
An over the range type will include home visits in the warranty, but not if it's a counter top model.
You'd have to take that type to the shop yourself, and of course that would mean unplugging it, which would reset it, and the repairman may never see if fail.
If you wait too long, your warranty will be expired, so I'd get in touch with the shop.

The problem you are having with your microwave is a common one. Not heating is a problem that can be caused by three things. I'll list the most common solution first, the magnetron that actually does the heating is what is making that noise and has gone bad. It is possible for you to also have a bad high voltage diode that has opened up, solution two, or solution three is the high voltage capacitor is not working properly as well. From my experience with microwaves I am positive that it is your magnetron that is bad. If you are not do it yourselfer you'll need to take it to a repair shop to replace. However, if you know how to use a screwdriver and can unplug a couple of wires with spade terminals on them, then you can take it off yourself, find another one and replace it the same way you took it off. The magnetron sits behind the control panel of your microwave but on top. It has cooling fins on it and has 2 terminals maybe three depending and make and model that plug into it. It has 4 screws that are easy to get to that actually holds it in place. If you do not have a good local source like an electronic parts supply place then you can find the right magnetron at www.mwoparts.com. Be sure you always unplug the microwave before touching or trying to take the he cover off and then when you take the magnetron off also.Good luck and God bless.
