Aluminum Foil and Metal

Always use oven mitts or pot holders when removing dishes from 
the microwave oven.

Aluminum foil and some metal can be used in the microwave 
oven. If not used properly, arcing (a blue flash of light) can occur 
and cause damage to the microwave oven.

OK for Use

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:

To avoid damage to the microwave oven, do not allow 
aluminum foil or metal to touch the inside cavity walls, 
ceiling or floor.

Always use the turntable. 

To avoid damage to the microwave oven, do not allow 
contact with another metal object during microwave cooking.

Do Not Use

Metal cookware and bakeware, gold, silver, pewter, non-
approved meat thermometers, skewers, twist ties, foil liners 
such as sandwich wrappers, staples and objects with gold or 
silver trim or a metallic glaze should not be used in the 
microwave oven.

Microwave Cooking Power

Many recipes for microwave cooking specify which cooking 
power to use by percent, name or number. For example, 
70%=7=Medium-High.
