Microwave display is on and timer counts down, but the turntable does not rotate.

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

• Check for obstruction: Remove the glass tray and turntable support ring. Clean any spilled food or debris from the cavity floor.
• Inspect coupler: Check the plastic turntable coupler that fits over the motor shaft. Replace if cracked or stripped.
• Test rotation by hand: With the tray removed, gently turn the coupler by hand. It should turn smoothly.
• Access motor: On many Hotpoint models, the turntable motor is accessible from the bottom after removing a cover plate. Inspect wiring and connectors.
• Replace motor: If the motor is seized or open-circuit (if you can test with a meter), replace the turntable motor.
