Kenmore Microwave 401.88529900 (40188529900, 401 88529900) Parts

This sub tray assembly is the interior support that holds and stabilizes the microwave turntable, helping the tray rotate smoothly for even cooking. The Teflon surface reduces friction and wear for reliable operation. What it does:

• Supports the glass turntable and helps it spin evenly during operation
• Reduces friction between the turntable and roller/drive system with a low-friction Teflon surface
• Prevents wobbling or sticking that can cause uneven heating
• Replaces worn, cracked, or missing sub trays that interfere with rotation

• Unplug the appliance before installing; follow all safety precautions
• Remove the glass turntable and any roller ring before replacing the sub tray
• Position the sub tray correctly on the drive hub and reassemble the roller and glass tray
• Do not operate the microwave without the turntable and sub tray in place
