How to Fix / Troubleshooting

Safety: Unplug before inspecting the turntable drive.

Steps:

  • 1. Check turntable setting: Some Tower models allow you to turn the turntable on/off. Verify it is enabled in the settings.
  • 2. Load and alignment: Ensure the glass tray is correctly seated on the turntable coupler and roller ring.
  • 3. Inspect coupler and tray: Remove the tray and coupler. Check for cracks or worn drive lugs. Replace if damaged.
  • 4. Motor test: With the tray removed, run the microwave briefly (with a cup of water) and observe if the coupler turns. If not, the turntable motor is likely faulty.

Advanced:

  • Access the motor from underneath and test it for continuity. Replace if open or seized.
