Question: Is A Sparking Microwave Dangerous?

What is the purpose of a microwave waveguide cover?

Additionally, it stops moisture and food particles from getting into the “workings” of the microwave..

Why is my microwave sparking and smoking?

Cooking your food too long in the microwave can cause smoke inside the machine. At times, it can even cause a fire. … If you notice sparks or smoke coming from the vent, it indicates that you are dealing with some serious electric problem inside the machine.

Can I use my microwave after it sparks?

This may occur again, but so long as the magnetron survives, you should be okay.
