Question about Microwave Ovens

1 Answer

I have a Sharp Carousel (R980A) microwave oven. The turntable intermittently doesn't turn. Everything else appears to be fine. I was looking to see if there is a schematic of the motor circuit anywhere. Or if you know where to look/and or replace any items in the circuit that may get it going properly.

Microwave lights, clock, and everything works except when you press start, it just counts down like its cooking, but the microwave is actually not on. No hum as usual or plate rotating. It just counts...


Hi, one of the most common reasons why the turntable won't rotate is that the microwave isn't clean. The turntable guide and carousel can get sticky, preventing the turntable from properly moving. If you have built-on food particles or liquids, fill a bowl with 2 or 3 cups of water and 1 tsp. of liquid detergent and lemon. Run the microwave for about 3 minutes. Clean the microwave with a cloth, including the base of the turntable, guide, carousel grooves and microwave base. Your microwave turntable won't rotate if the grooves on the base of the turntable do not sit right on the carousel. Also, check the position of the turntable guide. Place the guide directly under the turntable. Remove the turntable, and then reposition it into the carousel grooves.
Motor The carousel motor is located beneath the base plate of the microwave. If the carousel isn't turning at all, check the motor. Disconnect the microwave from the power source, and remove the turntable, guide and base plate. Try turning the motor to see if it's just stuck. If it doesn't turn freely after a few seconds, examine the motor to see if it's burned out or corroded. Use an ohmmeter to see if the motor has continuity. If not, you must replace the motor.
Bushings The drive bushings are plastic components that sit underneath the cooking plate. Remove the plate, and examine the bushings. Use a magnifying glass if necessary to see if any debris is caught in the plastic. Clean the bushings, and reinsert the plate. Turn the microwave on to see if it rotates. If the bushings are extremely worn or if some of the plastic is broken off, you need to replace it, which is a complicated repair for consumers. Contact a service technician for assistance.

Looks like you have the purchase the glass tray in order to get the coupler. I would give Reliable Parts a call though phone # is 1-800-666-0313. Give them your model number and the name of the part you need.

Built-in Sharp Carousel II Microwave Convection Oven died.


There are a couple of safety thermostats in the oven to shut down power if something overheats. One is on the magnetron tube (the microwave source), the other is on the cooking cavity. These sometimes go bad. There's also a power line fuse that may have failed, or become loose in its mounting clips. These can be tested with an ohmmeter; they should all measure very close to zero ohms if they're good.

Another possibility is that the control circuit board in the oven may have failed. I have worked on several Sharp ovens where the power transformer for the board has gone bad for no good reason. If the board goes bad the oven may appear to be dead as well.

Microwave servicing is best left to professionals. If you're thinking of keeping this one, take it to a service shop (or call for home service) and get an estimate. Then decide whether to repair or replace.

Hope this has helped a little. Thanks for using Fixya!

The carousel in our Sharp Microwave/Convection Oven suddenly stopped turning. Nothing seems to be blocking it--it whirls around when I push it. Any ideas?


Got someone to come look at it, and the motor for the turntable has burned out! We're ordering the part!
Thank you!

Sharp Carousel Microwave Model R520-LK timer will run but carousel doesn't turn and food doesn't heat.


I also have the Sharp Carosoul oven, symptoms - fan runs, controls are fine but the turntable stopped turning and it did not heat. It was not the switches, fuse, but in fact a sagging door that misaligned with the door switches. The true cause was a warn top hinge. As a temporary fix, I adjusted the bottom hinge (3 screws underneath), straightened the door, and now it works again.

Sharp carousel microwave doesn't spin


The turntable system consists of the motor, the coupler, the turntable support with rollers, and the tray.

You can see and hear a video of how a turntable motor should sound when you rotate it by hand.

If yours is not set to be off via the control panel, and it won't rotate or it sounds like it's grinding, etc., you may have a bad motor or plastic coupler.

To replace either, you need to unplug power, then remove the bottom cover of the oven. In some brands, you have to cut the motor cover off with snips, then use a screw when reassembling it.

The best place to order Sharp parts is Tritronics. You can also call them at 866-779-5835

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.
