Has anyone replaced the Turntable Coupling?

The Turntable Coupling broke on my oven. I have ordered a replacement part. Does the part just pull off the motor shaft. Do I have to disassemble it to get a clip or something out before it will come off?

    similar problem ... oven works fine but table intermittanlty turns ... hangs often .. would repacing the motor help or is ther more to the turning mechanism .. when it hangs it clicks.

  • rjm45 Apr 15, 2009

    if there is no weight on the 'thing' that turns - it turns ok - but once there is weight on it - it struggles to turn and creates that clinking noise.

    My turntable hangs up also.  This unit is installed inside my motorhome and would really like to fix it without removing it if at all possible.  Maybe it is still okay even if it doesn't turn??  Help me please

You will need to remove the motor to get it off.

We have the full R-930AK/AW service manual for this model and have uploaded it to our site here to help you.

You will need the free Acrobat Reader to view or print it.

Here's the procedure:

1. Disconnect the oven from power supply. Remove the turntable tray, and the turntable support out
of the oven cavity.
2. Turn the oven upside down and remove one (1) screw holding the turntable motor cover to the base plate and take off the turntable motor cover.
3. Disconnect wire lead from the turntable motor.
4. Remove the two (2) screws holding the turntable motor and coupling mounting plate to the oven cavity bottom.
5. Turntable motor, Coupling mounting plate and Thermal protection plate bottom will be free.

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

I just fixed mine! I unscrewed the door on bottom of microwave, and then unscrewed the two screws holding the motor. If the motor is your problem, then you can replace it right there. Very simple. If the coupling is your problem, like in my case, then it looks like I didnt even need to open up the bottom. I ended up prying up the coupling with a screwdriver from inside the oven. I snapped right out, then I snapped the new one in. I screwed the motor back on, making sure the motor shaft was in the coupling. Then screwed the door back on. Simple!

My Microwave-convection oven was purchased in November, 2008. It should still be under warranty. The place the Service number gave me to repair this oven has either moved or changed phone numbers. I need to have my turn table fixed because it does not revolve anymore. I have been trying for a month to get in touch with the repair people only to find out today 3/13/09 that the number given me was wrong. I am not mechanically inclined so I need a repairman. Please help me. I livem in South Jersey.

My turntable doesn't turn

Sounds like the turntable drive coupling is broken. In the bottom of the microwave where your turntable is, underneath that is a small drive coupling that the motor shaft pushes into. if the motor doesn't turn or the coupling, which commonly has a D shape shaft to keep it from slipping, is broken, the tray will not turn. One quick test it to remove your tray and see if you can turn the coupling easily by hand, if you can you probably have a broken drive coupling. The turntable motor is very difficult to turn by its shaft. so if it turns easily it is probably a broke coupling. NEVER force your turntable around by hand or you can break that coupling.

That may be called the turntable coupler or turntable support or roller ring assembly.

You can find helpful exploded views and part numbers at the link below, by replacing XXX with the full model number found on the tag on your microwave (not on the service manual).

My turntable has stopped turning - can anyone help please

The turntable is driven by a motor under the bottom of the cooking cavity. A plastic coupling that slides over the motor shaft, and that's what turns the turntable. In some ovens the coupling is a separate small piece that the glass tray sits on. Other models use a large wheeled plastic ring that rotates the tray.

The usual reason the turntable stops is that the coupling breaks or wears out. The motor shaft is D-shaped, and sometimes the plastic coupling cracks so it doesn't grip properly. Or the plastic wears so that the opening gets rounded and won't grip the shaft. Then even though the motor is running, the coupler doesn't turn. You can usually lift the coupling off the shaft to check it. In some ovens the coupler can only be removed by taking out the turntable motor, but that's not common.

A second possibility is that the turntable motor has failed. In most ovens there is an access panel on the bottom that comes off to get at the motor. You can check the motor with an ohmmeter across its terminals to see if it's good. (Usually I advise against trying to repair a microwave yourself, but replacing a turntable motor usually doesn't involve removing the cover. It's not a dangerous repair.)

If the motor checks OK (not showing infinite or very high resistance with an ohmmeter), you can check for power at the motor when the oven is running. This is a little more difficult because it means there will be AC line voltage present, so caution is needed. If there isn't power, it means there's some electrical problem to be solved, like a bad connection or trouble on the control circuit board.

The coupler and motor are both replaceable, although not always easy to find. Sears parts and Encompass are U.S. sources for many brand parts. You can also search online or check with appliance servicers in your area. If the problem turns out to be electrical, you should leave the servicing to a professional. Internal repairs involve hazardous voltages and possible microwave leakage if done improperly.

Depending on what you find is wrong and the cost of the parts (and labor, if you aren't able to fix it yourself), it may be more economical to replace the oven. For a basic counter-top model, it may not cost much more just to buy new, and you'd have a warranty. In the meantime, you can still use the oven, but you'll need to stop the cooking and turn the food occasionally to get even cooking.

Good luck, happy cooking, and thanks for using Fixya! If this has been helpful, please take a moment to leave a thoughtful rating.

My microwave is still working but not rotating, what is wroong with it

There's a turntable motor in the bottom of the oven that drives a turntable support directly in some models, and a plastic coupling that rotates the turntable in others. Turntable motor failure is common, or there could be connections in the power to the motor that have gone bad. Sometimes the plastic of the turntable coupling cracks, and the motor shaft turns but the turntable doesn't.

You can check a turntable motor with an ohmmeter. A good motor will show fairly low resistance (a few hundred ohms or less) between its terminals, while a very high or infinite reading means it's bad. In most models of oven you get at the motor through and access panel on the bottom. Replacement motors for many brands are available, although they're not always easy to find.

It may be more economical to replace the oven if it's a basic counter top model. They are under $50 these days, and a replacement motor might cost $20 or more. Of course, you can continue to use the oven even if the turntable doesn't, you'll just need to turn the food yourself occasionally during cooking.

Hope this helps. Thanks for using Fixya!

Two possibilities: either the turntable coupling is broken or the turntable motor has quit. The plastic coupling can wear or crack so it no longer fits properly on the turntable motor shaft. Then even though the motor still turns, the turntable doesn't. Or the motor itself may have stopped working. If the plastic coupling still looks normal and you can't rotate it easily by hand while it's in place, it's probably the motor.

I'm here in the US so I can't suggest where to find parts, but you should be able to locate a supplier who might have replacements available. Of course the oven will still work without the turntable running. You'll have to open the oven occasionally and turn the food yourself to insure even cooking.

Need to replace melted carousel coupling

You need to remove the bottom cover if it's an over the range model.

If it's a counter top type, there should be a cover over the turntable motor.

On many Sharps, the turntable motor cover comes as an unseparated part of the bottom cover and you have to use sidecuts or snips to cut away the little tabs which hold it in place. Then when you are done, you use a screw to hold the cover back in place.

All this is best done with the microwave on its left side with the door opened, and the turntable and support removed. (Power off, of course).

Once the cover is off, you remove the two screws holding the motor, pull the motor out, then pull ou tthe old coupler.

Install the new coupler with one hand, and push the motor in place. Jiggle the couple as you do so it will mesh with the motor shaft.

Once it's in, replace the motor screws, replace the cover and you are done.
