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. That's the giveaway.
See the attached sample
drawing for a typical damper assembly.
We have the applicable
service manuals for some of these models and have uploaded them to our site here and here to help you.
Hopefully these cover your model number, which you didn't mention.
If a switch is all you
need, we offer a universal type for only $5 postpaid which you can
order here.

If it consistently runs for exactly 59 seconds, and shuts off, it's probably the control panel.
If it runs approximately that length of time, you might have a defective thermal protector on the magnetron, or the magnetron is running too warm for some reason.
Check that a "favourite" setting has not been selected. The unit may think that is the time that you want to cook. Im not sure about your model but see if there is any clear or cancel buttons to clear any pre programmed selections. If not, unplug the machine for 15 minutes to reset the controller and try it again.

My sharp microwave convection oven (R-1870) runs for 59 seconds and stops. If I push start it runs for another 59 seconds and stops. How can this be fixedd?
