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 oven. If not 
used properly, arcing (a blue flash of light) can occur and cause 
damage to the oven.

OK for Use

Racks and bakeware supplied with the oven (if supplied), 
aluminum foil for shielding, and approved meat thermometers 
may be used with the following guidelines:

■

Never allow aluminum foil or metal to touch the inside cavity 
walls, ceiling or floor.

■

Always use the turntable. 

■

Never allow contact with another metal object during 
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 oven.

power to use by percent, name or number. For example, 
70%=7=Medium-High.
