Customer Questions and Answers for Microwave Turntable Support Ring (Roller Guide) by Whirlpool

This turntable support ring sits beneath the microwave's glass tray and rides on rollers to enable smooth, even rotation. Replacing a worn or damaged ring restores stable tray movement, reduces noise, and helps food heat more consistently.

• Supports the glass tray and distributes its weight as it rolls
• Works with the turntable coupler/motor to rotate the tray during cooking
• Helps maintain even heating by keeping the tray level and rolling smoothly
• Replace if cracked/warped or if rollers are worn; symptoms include tray not turning, intermittent rotation, scraping/grinding noises, wobbling, or uneven heating

• Disconnect power before servicing the microwave
• Remove the glass tray; lift out the old ring and clean the track area
• Position the new ring with rollers facing down; reseat the tray on the coupler
• Test rotation; if the tray still doesn't turn, inspect the coupler and turntable motor
