Aluminum foil and some metal can be used in the Maytag microwave oven. If not used properly, arcing can occur and cause damage to the microwave oven. Racks and bakeware supplied with the microwave oven (on some models), aluminum foil for shielding, and approved meat thermometers may be used with the following guidelines:

• Always use the turntable. 
• Do not allow aluminum foil or metal to touch the inside cavity walls, ceiling, or floor. 
• Do not allow contact with another metal object during cooking.
