The carousel and the cooking power just stopped working...this thing is practically new and hardly used..it just doesn't make sense.

Possibly a bad door switch behind the holes where the latch hooks go into. Usually with the bad switch the timer counts down but nothing runs. It all depends on which switch is bad. Usually 3 switches inside.

If all the settings work and the door closes ok . why throw it out ?. It may not be quite as efficient power wise as a brand new one. the few cents extra to run it against the price of a new one, I would stay with old faithful.

There are door switches and one of them is evidently out of adjustment or the little actuator arm on it is.

If it stops after 59 seconds, this is a problem in one of the damper-related components, either the damper switch or damper 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.

If you had mentioned your model number, I could have possibly given you a link to the service manual.

So I'll just give you a general answer and say that you can find Sharp exploded views and order Sharp parts from the Sears Parts Direct Web site.

If it's random or intermittent, chances are it has a bad top or bottom door switch or door switch mount.

The first thing to try is to do a hard reset.

Unplug the unit for a minute or so. Then plug it back in, set the clock and try again.

If that doesn't work, leave it unplugged for about 5 minutes.

If it still doesn't work, it may need repair, which can be done for $39.95 in most cases.

It's probably a bad door switch or door switch mount, probably the top one, which is the door sensing switch.

We have the actual service manual for this model and have uploaded it to our site for you here.

If the Damper Switch loose contact will couse this problem,try to clean the contact of the damper switch and damper motor .

I too believe that a "protection fuse" was possibly blown. It would need to be found and get replaced. Hopefully it is just a fuse and nothing else because the way it sounds to me, the microwave may be damaged.

Good Luck!

Because the microwave energy is beamed into the interior of the microwave and then dispersed by a metallic "stirrer," the pattern of the energy can be fairly consistent, rather than completely random. But this pattern sometimes causes certain portions of the food to overcook (creating tough spots) and others to undercook. A microwave oven with a carousel is far better at cooking the food consistently--the pattern becomes quite random while the carousel is turning.

That's how it would sound if you were cooking on a power level less than full power.

If you enter the cooking time and hit Start, it should cook at full power by default and not cycle like you describe.

If you are using some sensor cook setting or automatic type cooking setting, it may cycle like that normally.

The first thing to try is a "hard reset". Unplug it from the power line for a minute, plug it back in, set the clock, then try again.

Let us know if the hard reset doesn't fix it.
