A microwave oven may include a metal component, like a shelf, if it is of the manufacturer's design. A manufacturer can properly design and place a metal component in a microwave oven by ensuring that it is not, and cannot become, a microwave antenna.

If a metal component is designed by the manufacturer, specifically for its ovens, it is safe to use (per the instructions). Utensils, aluminum foil, gilding, and other metal objects act as antennae causing arcing and possible fires, and may cause damage to the oven.

Metal shelves can be used in microwave ovens if they are constructed with materials that do not absorb microwaves. The metal shelf acts as a conductor and does not interfere with the microwave's ability to heat food. However, it is important to follow the manufacturer's guidelines for safe use of metal shelves in a microwave oven to prevent any potential safety hazards.
