Microwave beeps and displays E6, often immediately after pressing Start.

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

Steps:

• Remove and inspect the glass tray: Take out the glass turntable and support ring. Clean any spilled food, debris, or broken glass from the cavity floor and roller track.
• Check the turntable coupler: Inspect the plastic coupler that fits over the motor shaft for cracks or melting. Ensure it sits properly in the cavity floor.
• Test operation without load: With the glass tray removed but the coupler in place, plug the unit back in and start a short cook cycle with a microwave-safe cup of water placed off-center on the cavity floor. Observe whether the coupler attempts to rotate.
• Listen for motor noise: If you hear a humming or grinding noise but no rotation, the motor may be seized.

Technician tasks:

• Access the underside of the cavity to test and replace the turntable motor.
• Inspect wiring to the motor and any position sensor used by the Hisense model.
