If you notice your microwave's tray is wobbling, not turning, or has become noisy, this guide roller might be the issue. Designed with an 8 13/16-inch ring radius, 5/8-inch wheel diameter, and 5/16-inch wheel width, it fits precisely under the tray. Verify your microwave’s model number to confirm compatibility before purchasing.
