Looks this model's turntable support has a coupler shaft built-in which is supposed to go down into the turntable motor hole and make contact with the turntable shaft. Is that right in your case?

So I would wonder if the turntable support has gotten bent due to heat. That's common on some models.

When you take it out and look at it from the side, are the legs straight and perpendicular to the shaft or are they bent down?

On some models, you can heat them over a stove flame, then put them on a flat surface with a weight to old them in position while they cool.

Otherwise, you'll need a new turntable support. LG / Goldstar calls this a "rotating ring".

Microwave turn table quit rotating


With the model number, we may have been able to give you a link to the actual service manual. Without it, we can only give you general answers.
The first thing I would suggest is a hard reset. Unplug the unit for a minute or so. Then plug it back in, set the clock and try again.

If that doesn't work, leave it unplugged for about 5 minutes, then try it again.

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.

Lately the turntable will "stick" and not turn


Your Turntable motor is going out. You can get replacement motors pretty cheap and they are very easy to change. They change out from the bottom of the microwave and have just two plugs.

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!

Hi I have an Emerson microwave oven MW8998B. The turn table will not rotate while cooking. The smaller bags of popcorn just burn the bag. Does this need a repairman or can I fix it myself. Also, I am able...


Hi, I had the same problem with my Emerson microwave. As I rent out the house, and the turntable stopped working while I was away, my rental agent bought another Emerson microwave. On my return I tried using the new (brown) plastic turntable on the old microwave, and found it worked perfectly. Maybe it would be possible for you to order a replacement turntable part. Hope this helps. Good luck, Rosalind

Hi there,

Well it seems that there is some fault in the turnable motor, turntable system consists of the motor and coupler, turntable support with rollers and the tray.
I have a video link to help you more on this -- how a turntable motor should sound when you rotate it by hand... please follow the below link -

If motor grinding... etc., it means you may have a bad motor or plastic coupler.

Post further comments if you need more help....

Goldstar 1310W built in


The following parts are in the turntable system: The turntable motor, underneath the floor of the microwave; the turntable coupler, which is like a small plastic piece; the turntable support, either a three-legged or circular piece with wheels; and the glass turntable tray.

It sounds like maybe your turntable support is missing?

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.

Some over the range models allow you to turn off the turntable via the keypad. Counter top models usually don't.

Smasung MW7490w door/turntable problem


It's probably a defective door switch, probably the upper one, or the mount which holds the switch is broken. Opening the door while cooking (without first hitting the STOP button) is the primary cause of door switch failure. There are plastic mounts inside the microwave which hold the door switches and onto which the door hooks latch when you close the door. The screws on these mounts may be loose. If they get too loose, the switches will not be activated properly. Usually it's not a loose screw, but instead a broken tab on the switch holder, allowing the switch to rotate just out of position.
