• ** REMEMBER! **The microwave can still shock you even unplugged!!

    ALWAYS discharge the high-voltage capacitor first if you even think your hands will come close to any HIGH VOLTAGE components.

    Jeff mentions this: Anything in the high voltage ( magnetron, capacitor, diode, wires to and from ):
    ...Use a metal ( not the shiny chrome type ) screw driver with a insulated handle to short across ( touch both at the same time ) the terminals of the high voltage capacitor to discharge it.

FIXED R930AK Older Sharp microwave convection oven carousel occasionally turns

This unit was produced in 2001. A few years ago, the carousel decided it would prefer to turn clockwise. The rare times it turns counterclockwise, it works great. Clockwise, not so much. It will turn a few times then just sit there and click. Thoughts?

Ha! Yah, I kinda came to the same conclusion — so what if it doesn’t turn? That said, the replacement motor is cheap enough it may be a worthwhile repair. Thanks, Dan!
so what if it doesn’t turn?
If the turntable isn't rotating you'll get uneven cooking and maybe a slight chance of the microwaves being reflected back to the magnipetron tube, shortening its lifespan. Mainly just bad cooking results.
My Sharp Carousel Smart&Easy Convection (Model R-930AK-P, about 8 years old) was doing the same thing. Sometimes I heard the clicking noise and would open the door and jiggle the rotating plate to make it turn again. After a few months of doing this, it stopped rotating. Once it stopped rotating, it stops heating up the food as well.

I downloaded the service manual from manualowl.com/m/Sharp/R930AK/Manual/330660
But I don't see this exact problem described, so I looked up the Turntable problem and the Heating problem separately.

I read Procedure H (on page 21/52 of the PDF) on Motor Winding Test.
BUT, I don't even know how to find the Turntable Motor!

Would someone please give me a tip?

I've also read in another forum that "There are 3 door switches and if 1 of the door switches fails, it will stop heating and the turntable motor will stop. You need to figure out which door switch has failed and then replace the faulty door switch."
But right now I am thinking it is not the door switches since I had the previous "clicking and not turning" issues. What do you think?
The turntable motor is under the unit. There might be a separate panel on the bottom that comes off to access it.

But if the unit stopped heating, the motor is either not the cause or there is an additional problem. If both stopped at the same time, I agree, looking into the functioning of the door switches is likely necessary.

BTW. If you decide to look into the motor, be sure to take the tray out of the microwave before flipping it over. New glass turntables are usually very expensive. Don't break it!

Dan O.,
Thanks for your reply.

Since I couldn't find anything that says if the Turntable Motor goes, the heating goes as well, we decided to look at the switches. (Plus that little Turntable Motor is so expensive! $54.78!)

Once we figured out which switch to out first and how to get it out, we noticed that the plastic was a little melted. So we ordered that part and got it quickly. Once it was replaced, the turntable is turning and the heating is working too!!

I think the turntable is clicking mostly when I am baking a casserole (heavy dish, I do use the wire rack). So maybe I'll stop doing that in the future.

Thanks again for your help!
