Re: sharp r-1610 microwave

It could be the turntable motor, the turntable support (with built-in coupler) or a problem on the control board. I would first look at the 3-legged turntable support with built-in coupler to see if it got hot and warped. It should be flat across the top from the center to the end of the legs. If the support's legs are pointing a bit downward, it will prevent the coupler from making contact with the motor shaft. I've held bent ones a few inches over a gas burner to heat them up where the legs meet the center hub, then set something a bit heavy on it to hold it in place while it cools. If it needs a new one, it is part # FROLPB025MRK0 and it runs $19.50 retail at Tritronics. A quick (but not necessarily definitive) test of the motor is to grab the shaft gently with pliers and gently try to turn it. If it moves slowly and makes a high-pitched whining noise, it's likely okay. If it won't turn or grinds, it is bad. The number for the new turntable motor is RMOTDA264WRZZ and it retails for $8.87. Please note that you may need to look under model R1600, R1600, R1601, R1601, R1610, or R1612. They are all mostly the same. Tritronics is at The service manual for the R1610, R1611, R1612 can be downloaded at: There may be a grommet bewteen the mtoro and turntable support. Don't lose that! Be safe!

Turntable not working

Remove the bottom cover to the oven and check to see if a rubber belt exists, if so it may have stretched and may be slipping. Replace the belt if one exists.

Microwave quit

Hi there,

Well first of all you can try to clean the turntable- Remove your glass turntable cooking tray from your microwave. Gently wash with warm soapy water to remove any debris. Next remove the turntable guide and clean it in the same manner, with warm soapy water. Pay particular attention to the turntable rollers. There could be spilled food particles caught in the rollers, hindering the rollers' movement. Also, gently cleanse the internal cavity of your microwave, paying special attention to the area below the turntable. With the internal cavity, turntable, and turntable guide completely clean and dry, return the parts to your microwave. First place the turntable guide on the bottom of the microwave. There should be a circular groove in the bottom of the microwave cavity keeping the turntable guide in place. Follow the guide with the turntable cooking tray. Carefully place the glass tray over the turntable guide and onto the drive bushing. The drive bushing should fit neatly into the grooves on the bottom of your glass cooking tray. It may take some adjusting before the tray will sit properly onto the drive bushing. If further you have the same problem then this could be a failing turntable motor...... Please post comments for further help or information.......

Good Luck!!

Light and fan stay on and turntable no longer work

Not sure if your model has a belt driven turntable or gear driven. The cause of your problem is most likely a worn or loose drive gear or a drive belt which is worn or has come off.
Best have this checked at your local repair shop.

Best wishes,

Turntable stopped working

Most of these are belt driven. You need to uncase the unit and check the belt.

Like anything with high voltage, use good safety practices.

The turntable makes noise and is jerky as it turns

I believe your turntable is belt driven as opposed to direct drive. Your little belt is nearing the end of its useful life, I think.

Remove the cabinet. Turn the oven on its back. Look at the bottom.

Sharp calls that the turntable coupler when it's a separate part.

If it's part of the the part with three legs, that is called the turntable support.

If yours is model R1610, we actually have that full service manual on our site at

Microwave turntable won't turn

You will have to take it out and then take off the outer cover to expose the drive system for the turntable unless the items turns with the turntable removed. If it does then (and if it is belt driven) the belt may be worn and slipping. Anyway you look at it the cover has to come off to see what is happening.

My turntable does not work.

The turntable is driven by a motor thru a fairly long belt which is no doubt stretched and worn out. It isn't very easy to get at either being underneath the unit.
