Product Overview

This image displays the clear glass microwave cooking tray. It features a circular design with a central hub and three small nubs on the underside, designed to fit onto the microwave's rotating mechanism.
The Thermador Microwave Glass Cooking Tray is a crucial component for even heating and cooking within your microwave oven. It is constructed from durable, heat-resistant glass, ensuring safe and effective food preparation.
Setup and Installation
Before installing the new cooking tray, ensure your microwave oven is unplugged from the power outlet to prevent electrical hazards.
- Unpack: Carefully remove the new glass cooking tray from its packaging. Inspect it for any signs of damage during transit. Do not use a damaged tray.
- Clean Microwave Interior: Ensure the microwave oven's interior, especially the turntable support area, is clean and free of food debris or spills.
- Position Turntable Ring: Place the turntable support ring (if applicable and separate from the tray) correctly on the microwave oven's floor. Ensure its wheels are properly seated in the designated grooves.
- Place Glass Tray: Carefully place the glass cooking tray onto the turntable support ring. The central hub on the underside of the glass tray should align with the coupler in the center of the microwave oven floor. Ensure the tray sits flat and can rotate freely.
- Test Rotation: Gently rotate the tray by hand to confirm it is properly seated and moves smoothly.
- Restore Power: Plug the microwave oven back into the power outlet.
Operating Instructions
The glass cooking tray is designed to rotate during microwave operation, ensuring even cooking. Always use the tray when operating your microwave oven.
- Food Placement: Place food containers directly on the center of the glass tray.
- Weight Limit: Avoid placing excessively heavy items on the tray, as this can strain the turntable motor and support. Refer to your microwave oven's main manual for specific weight limits.
- Rotation: The tray will automatically rotate when the microwave is in operation. Do not obstruct its movement.
- Hot Surfaces: The glass tray will become hot during and after cooking. Always use oven mitts or heat-resistant gloves when removing hot dishes or the tray itself.
Maintenance and Cleaning
Regular cleaning of the glass cooking tray is essential for hygiene and optimal performance.
- Daily Cleaning: After each use, wipe the tray with a damp cloth and mild detergent to remove food splatters.
- Deep Cleaning: For stubborn food residues, the glass tray can be removed and washed by hand with warm, soapy water. It is also generally safe for dishwasher use, but consult your microwave oven's main manual for specific recommendations.
