Often mistaken for disposable plastic, the turntable support ring beneath a microwave glass tray serves a vital functional purpose.
By balancing the glass plate and allowing it to roll smoothly, the ring enables continuous rotation during the heating process.
This steady rotation moves food through varying microwave intensities, helping to reduce cold spots and ensure more even heating.
Regularly cleaning crumbs from the track beneath the ring and replacing damaged wheels ensures your microwave operates efficiently and reliably.
