Common Causes of Microwave Sparking
Microwave sparking can be caused by several factors, including the presence of metal objects, damage to the microwave’s interior, or even the type of food being heated. Metal objects can reflect microwaves, causing sparks and potentially damaging the appliance. Additionally, wear and tear, such as a damaged waveguide cover or a malfunctioning magnetron, can also lead to sparking.
Identifying Metal Objects Inside the Microwave
One of the most common causes of sparking is the presence of metal inside the microwave. This can include aluminum foil, metal utensils, or even metallic trim on plates or containers. It’s important to thoroughly check the contents of your microwave before starting it to ensure no metal is present.
