General Arcing and Sparking - Built-In Microwave

Possible Solutions

Prolonged arcing can damage to the oven and/or the utensil. 

If caught at once, arcing should not damage the oven. Remove the offending utensil or food from the oven and either substitute a microwave-safe utensil or cook the food by other methods.

Are the utensils and/or cookware microwave safe?

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. If used they could cause sparking or arcing in the microwave.
