Chances are your thermistor is defective.
This UK model is probably similar to the US model R-930 or R-820.
We have both service manuals at our site and while the part numbers will not necessarily be the same, they will be handy for safety, disassembly and troubleshooting. They are here and here.
When you're ready to order parts, visit Sharp UK for spares dealers and servicers.

You probably have a bad thermistor.
You can usually find
helpful exploded view diagrams and order parts by entering your full
model number here.
(At that site, that part is misspelled as "thermister" for your model).
There
should also be a "mini-manual" hidden inside the unit behind the
control panel or hidden on the left side behind the grille, which is
very
helpful
when troubleshooting & testing.
At
our Web site, we have a video
available showing how to remove a typical
over the range control panel assembly in under 5 minutes.
Accessing some components for testing will require you to remove the oven from the wall.
If
so, the installation instructions are very handy, and it's best to have
two people since the microwave can be heavy and awkward.
You can download GE
owner's manuals and installation instructions here.

I would first suspect the thermister (thermistor) or a low line voltage, weak control board relay etc.
But the service manuals will show you how to safely disassemble, test and repair the unit.
We have
the service manuals for this model and have uploaded them to our
site here and here to help you.
You will need the free
Acrobat Reader
to view or print them in case you don't have it.
The best place to order
parts for this brand is Encompass (formerly Tritronics). Or you can call them toll-free at 866-779-5835.
Feel free to contact me directly (and please remind me of your
full model number) for more information & help.

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
photo for a typical damper assembly.
