The LG MJS47373304 Oven Glass Tray provides a stable surface for holding and heating food inside compatible microwave ovens. This circular glass tray sits on the turntable support and rotates during operation, allowing heat to distribute more evenly around the food. It operates by resting on the rotating ring beneath it, which moves the tray smoothly while the microwave runs. Installed at the base of the oven cavity, the tray can be easily removed for cleaning or replacement when damaged. By supporting balanced rotation and steady placement of dishes, this component assists in consistent heating performance and helps maintain proper operation during everyday microwave use.
