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

If yours 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. You may have to cut the cover off with snips, then use a screw when reassembling it.

We have the full service manual for this oven, and have uploaded it to our site here.

The best place to order Sharp parts is Tritronics.

The dial on our GE JVM1790WK01 microwave turns freely but does nothing. I checked the knob for damage, none found and the shaft turns freely with a slight bump as it goes around, but does nothing.


turntable problem? it's probably the motor itself. it's easily removed under the bottom panel. you'll need the pricey ge orig. part; as they use a odd 21volt motor. good luck.

Our turn table doesn't turn anymore . . . Please help. thank you!


If the oven is still heating, but the carousel isn't turning, this problem is commonly attributed to a turntable motor that has worn out and may need to be replaced. The motor is attached to the center plastic piece (called a turntable shaft, turntable ring or coupler) under the middle of the glass tray. The following link explains how to access and replace the motor:

This is a very simple repair, that usually is not expensive. The price range will be determined by the model and manufacturer. This repair can also be performed on an over the range model microwave oven WITHOUT uninstalling it.

You can refer to any of the following websites for comparison:

searspartsdirect.com
pcappliancerepair.com
appliancepartspros.com
repairclinic.com

The first three sites listed have helpful exploded view diagrams to assist you with locating and properly identifying the part(s) you need.

If you have any questions, please post back with your MODEL NUMBER and let me know. I hope this helps you.

I have a Sharp 930 Convection Microwave that is no longer rotating. Any help?


This problerm is commonly attributed to a turntable motor that is no longer working. If the model number you posted this question under is correct, the part number for a replacement turntable motor is 46-841666-3. You may also consider replacing the turntable coupler (also called the turntable shaft). The part number is NCPL-A021WRFO. If your existing coupler is still in good shape, there is no need to replace it.

Replacement parts can be purchased on line at searspartsdirect.com. There is a complete list of helpful exploded view parts illustrations to assist you with parts identification/location.

Turn table doesn't turn. The middle peg doesn't move.


The microwave oven does not have a drive belt for the turntable. The component you describe that the carousel plate sits on its called the turntablel shaft or turntable coupler and it is attached to the turntable motor. This problem is commonly caused by a turntable motor that has worn out and needs replaced. The following link explains how to access and replace one:

http://www.fixya.com/support/r3555716-replacing_a_turntable_motor_on_a_microwa

This is a very simple repair, that usually is not expensive. The motor usually averages about $35 - $40, but the price also depends upon the model. This repair can also be performed on an over the range model microwave oven WITHOUT uninstalling it.

You can usually purchase replacement parts at the any of the following websites:

searspartsdirect.com
pcappliancerepair.com
appliancepartspros.com

Has anyone replaced the Turntable Coupling?


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.

Turntable not moving, otherwise micriwave works.


If the rest of the oven works fine, then this indicates that you might have a problem with the motor that turns the turntable.

If you try to turn the turntable manually (gently), does it turn freely or is there resistance? If it turns freely, the mechanical mechanism between the turntable and motor may be broken and the motor may be ok.

The oven's microprocessor2.gif also controlls the motor. There could be a problem there.

You'll need to have it looked at by a service center. Although its not that difficult to determine which of the reasons I mentioned above is the cause, it can be however, dangerous to operate a microwave oven with the cover off and with high voltage circuits exposed.

Please let me know if I can be of further assistance to you.

Good luck!
