Microwave turntable rotates intermittently or makes grinding/clicking noises while turning.

Safety: Unplug the microwave before cleaning or inspecting the turntable system.

Steps:

• Remove and clean: Take out the glass tray and roller ring. Clean them and the cavity floor thoroughly.
• Inspect for damage: Look for chips or cracks around the center of the glass tray and flat spots on the roller ring wheels.
• Test without load: With the tray removed, plug in the microwave and run a short cook cycle. Observe the coupler. If it turns smoothly and quietly, the issue is likely with the tray or ring.
• Replace damaged parts: Replace the roller ring or glass tray if damaged.

If the coupler itself wobbles or makes grinding noises, the turntable motor may be failing and should be replaced by a technician.
