Microwave displays E07 and will not start; often associated with turntable not moving.

How to Fix / Troubleshooting

Safety: Unplug the microwave before touching the turntable drive components.

Mechanical checks:

Remove the glass turntable and roller ring. Clean both thoroughly and remove any food debris from the cavity floor.
Inspect the plastic turntable coupler (the piece that fits over the motor shaft) for cracks or melting. Replace if damaged.
With the glass tray removed, gently rotate the coupler by hand. It should turn smoothly without grinding or binding.

Test:

Reinstall the roller ring and glass tray correctly.
Plug the microwave back in and run a short test. Observe whether the turntable rotates. If E07 reappears, stop the test.

Technician checks:

Test the turntable motor for correct resistance and replace if open or seized.
Inspect wiring and connectors from the control PCB to the motor.
Check the control board output to the motor relay or triac.

Do not force the turntable; if the motor is jammed or noisy, it should be replaced.
