Question about GE Spacemaker JVM1640SJ Microwave Oven
With nothing on the glass plate, or with a light item, it turns. Moderate to heavy weighted items no longer turn. Started a few weeks ago. Microwave been in use for about 3 years.
I would say an internal post broke inside the motor. This often happens when a heavy item is placed on the tray.
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.
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 Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.
You can find helpful exploded view diagrams and order parts by entering your full model number from the tag on the oven here.
