What Causes Microwave Sparks?
There are several reasons why your microwave may be sparking. Some of the most common reasons include:
1. Metal in the Microwave
One of the most common causes of sparking in a microwave is the presence of metal. When metal is placed inside a microwave, it can create a phenomenon known as arcing. This is when an electrical current jumps from one piece of metal to another, creating sparks.
2. Damaged Waveguide Cover
The waveguide cover is a small metal panel that covers the opening where the microwaves enter the cooking area. If this cover is damaged or has a hole in it, microwaves can escape and cause sparks.
3. Dirty Microwave
If your microwave is dirty, food residue or other debris can cause sparking. This is because the debris can create a conductive path for the microwaves, leading to arcing.
4. Faulty Magnetron
The magnetron is the part of the microwave that produces the microwaves. If it is faulty, it can cause sparks.
What Should You Do If Your Microwave Is Sparking?
If you notice sparking in your microwave, the first thing you should do is turn it off and unplug it. This will prevent any further damage or safety hazards. Once you have unplugged the microwave, you can begin to troubleshoot the problem. Start by checking for any metal objects inside the microwave. If you find any, remove them and try using the microwave again. If the problem persists, check the waveguide cover for any damage or holes. If you find any, replace the cover. If your microwave is still sparking, try cleaning the inside of the microwave thoroughly. This includes the turntable, walls, and ceiling. If none of these steps resolve the issue, the problem may be with the magnetron. In this case, it is best to call a professional to repair or replace the faulty part.
