Customer Questions and Answers for Turntable Support Ring (Microwave) by Bosch

This turntable support ring sits beneath the microwave glass tray and lets it rotate smoothly for more even heating. Replace a worn or warped ring to restore consistent tray movement and reduce scraping, binding, or wobble during operation. What it does:

• Supports the glass turntable so the drive system can rotate it smoothly
• Helps maintain steady rotation for more consistent cooking results
• Replace if the tray stalls or binds, wobbles, or makes scraping/grinding noises while turning
• Wear or deformation can cause intermittent or noisy rotation

• 1 turntable support ring

• Disconnect power to the microwave before servicing
• Remove the glass tray; lift out the old ring and clean the track on the cavity floor
• Set the new ring flat in the track and reinstall the tray on the drive coupler
• Test rotation with a microwave-safe cup of water; never open the cabinet—microwaves contain high voltage
