Microwave turntable won't turn

Make Sure the plastic ring with the wheels on it is underneath the turntable. Maybe the teeth of the turntable are not engaging fully with the teeth on the microwave. If not you could cut out some small 16th inch thick plastic sticky squares and put them on the high points of the teeth of either the microwave teeth or the turntable teeth. no metal Sticky pieces you know what happens one metal is in microwave .
Maybe the small motor underneath the microwave as loosened and has dropped down a little so that it is not engaging with the turn table fully.
Hope this helps.

check for the roller spider under the plate
small plastic item that has 3 (4) rollers that allows the plate to turn freely

This problem is commonly attributed to a turntable motor that has worn out and may need to be replaced. The motor is attached to (and is located under) the center plastic piece (called a turntable shaft or coupler) under the middle of the glass tray that you were referring to. The following link explains how to access and replace one:

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:

repairclinic.com

The first three sites listed offer helpful exploded view diagrams to assist you with locating and properly identifying the part(s) you need. If the model number is correct, the part number for a replacement motor is WB26X10135.

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

It's normal for the motor to turn both ways, that's because of how the motor is made. As for the grinding noise, there's no reason the motor itself would make more noise turning one direction than in the other. The noise might be coming from the roller ring under the glass turntable. One of its wheels might be binding when it tries to turn counterclockwise.

Here's a test. Take the glass tray and roller ring out of the oven. Put a microwave-safe container with a cup or so of water in the oven and start it. Stop the oven and start it again, and the motor should turn the other way. If not, repeat this until you've seen the plastic coupling turn both directions. Note whether you still hear the noise as the motor turns each way. If you do, then there is something wrong with the motor and it should be replaced. If not, the noise is coming from the roller.

In either case, if the oven is truly only a month old it's still under warranty. Since you are concerned about the noise and are worried that the oven is defective, contact the store where you purchased it and see if they will exchange it or take it in for service. If the store can't help you, refer to the owner's manual for the service procedure to follow.

Hope this helps. Thanks for using Fixya!

Sounds like the "hub" for the turntable is worn. either that or the actual turntable motor. also insure the "plate" has a ring under it with wheels. sometimes I find those missing which in turn put far too much loud on the hub & motor, hence wearing them out pre-maturely.

you should be able to pull the hub out from inside the oven, if not. remove the filters below and if you twist just right you should see a small round device mounted with two tiny philips head screws, that's the turntable motor. It's usually the "hub" that wears though, so it's likely an easy fix. The most difficult part may be finding the new replacement part itself.

hope that helps,

good luck

It could be a failing fan motor or magnetron.

While a microwave should never be left running unattended under any circumstances (as your owner's manual will tell you) it's even more important when one is exhibiting a failure or any odd behavior. So play it safe and stay with it while it's running!

And, as with anything that is not working right, it should be fixed as soon as possible or it can get worse.

If it's less than one year old, it would be fully covered under warranty. I'd suggest contacting the manufacturer to get it fixed free.

Sounds like you haven’t correctly centered the ring assembly under your glass platter. Remove the glass platter, now place the plastic ring with tiny wheels in the center and move it around by hand. You will be able to tell instantly if it’s centered correctly. Now place the platter on the center hub gear.

Unplug unit and take bottom off of it with the screws that go around the outer edge. The turnatanble motor has 2 screws and is removabe from the bottom underneath.

You can find helpful exploded view diagrams and order parts by entering your full model number from the tag on the oven here.

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.

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 http://www.wehaveparts.com The service manual for the R1610, R1611, R1612 can be downloaded at: http://www.microwavedisplay.com/R1610.pdf There may be a grommet bewteen the mtoro and turntable support. Don't lose that! Be safe!
