Microwave Arcing or Sparking - Combination Wall Oven


Possible Solutions

NOTE: Whatever the cause of Arcing (a blue flash of light), turn off the oven immediately.

Prolonged arcing can damage 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.

Is the cooking rack being used for only 1-level cooking?

Use the cooking rack only for 2-level cooking.  Always remove the rack after 2-level cooking to prevent damage to the microwave oven.
