Question about Jenn-Air JMC8100 Microwave Oven
The glass plate inside the microwave will no rotate. How can you help?
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.
You can usually find helpful exploded view diagrams and order parts by entering your full model number here.
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.
We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

It's probably a cracked coupler or a weak, slipping motor.
