A microwave equipped with a turntable has a drive motor in the center of the oven floor that spins the turntable. The turntable is made of glass and has grooves on the bottom of it which seat in the internal grooves of the drive-motor bushing. The outer edges of the glass turntable ride on a turntable guide equipped with wheels. These wheels roll in a groove in the bottom of the oven floor. When food particles gum up the wheels of the guide, squeaking occurs.
