Microwave turntable does not rotate, but heating and other functions work.

Safety: Unplug the microwave before accessing the turntable motor from below.

• Check setup: Ensure the glass tray is seated properly on the center coupler and that the roller ring is correctly positioned and clean.
• Test without load: Remove the tray and roller ring, then run the microwave briefly with a cup of water off to the side. Look through the window to see if the center coupler turns.
• Clean components: Wash the tray and roller ring with warm soapy water, dry, and reinstall.
• Motor replacement (advanced): If the coupler does not turn, the turntable motor under the cavity is likely faulty. Replacing it requires removing the bottom cover and should be done by a technician.
