Readers ask: Microwave Started Arcing When Trying To Cook Meatballs?


Why is my meat sparking in the microwave?

Minerals and metal These minerals – which include iron, magnesium, and selenium – act like tiny pieces of metal and create what is known as an “ arcing effect” in microwaves. An arcing effect is when sparks occur as a result of electromagnetic waves in a microwave reflecting or bouncing off metal.

Why is my microwave arcing?

Arcing, seen as sparks or flashes within the microwave oven, occurs when electromagnetic waves emitted from the magnetron during cooking strike a metallic or reflective surface. The container or cookware used during cooking may also cause arcing if it is unsuitable for microwave use.

Since those minerals act like “tiny pieces of metal,” microwaves bounce off them just like they would a fork, causing the sparking effect.

Is it safe to use a microwave without the waveguide cover?

You can use your microwave without a waveguide, but when the waveguide is damaged, the steam and vaporized food particles collect on the oven’s electronic components.
