Question about Microwave Ovens
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.
There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.
At our site, we have a video showing how to remove a typical over the range control panel assembly in under 5 minutes.

That model number doesn't ring a bell. Is that right? Is it foreign?
Chances are the coupler and/or turntable support will be damaged or warped.
Also on some brands, the "packing" (often a rubber grommet) must be replaced.
