Microwave shows E7 and turntable does not rotate during cooking

Safety first: Unplug the microwave before accessing the underside or internal components.

• 1. Check for mechanical obstruction: Remove the glass turntable and roller ring. Clean any spilled food or debris from the cavity floor. Ensure the roller ring moves freely and is not warped.
• 2. Inspect the coupler: The plastic turntable coupler that fits into the motor shaft should be intact and firmly seated. Replace it if cracked or melted.
• 3. Test without load: With the glass tray removed, run the microwave for a few seconds (with a microwave-safe cup of water in the cavity). Observe whether the coupler attempts to turn. If it does not move at all, the motor or its wiring may be faulty.
• 4. Access the motor (advanced): Unplug the unit, remove the outer cover, and access the base. The turntable motor is usually mounted under the cavity floor. Check the wiring connectors for secure fit and signs of burning.
• 5. Replace motor if needed: Test the motor with a multimeter for continuity. An open circuit indicates a failed motor. Replace with a compatible Russell Hobbs turntable motor.
