You can try and unplug it for 5 minutes, push the on button to make sure it's completely discharged. Then plug it in. If it does the same thing, it's toast. Getting it repaired will cost about the same as a new one on sale.

This is usually caused by either a bad door switch, a loose door switch mount, or occasionally a problem on the control panel.
Door
switch or mount trouble can be caused by slamming the door or by
opening the door while it's cooking without hitting the Stop pad first.
There
are plastic mounts inside the microwave which hold the door switches
and onto which the door latches lock when you close the door.
The screws on these mounts may be loose. If they get too loose, the switches will not be activated properly.
Sometimes
it's a broken tab on the switch holder, allowing the switch to rotate
just out of position. This tab
can be hard to see, since it is under the bottom edge of the switch.
If
you or someone you know decide to look into it, we have critical
information on safety, disassembly and door switches at our site, and
our link is at our listing here on FixYa:.

Wow. I just read something ridiculous!
Well, never mind that, here's your solution:
This
is a common problem in one of the damper-related components, most likely the
switch, but it may also be the motor or the damper door.
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
photo 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. You will
need the free
Adobe Reader
to view or print it.
If a switch is all you
need, we offer a universal type for only $5 postpaid which you can
order here.

This may be due to the microwave section not working. Check the high voltage diode if it is ok, replace the Magneton.
