Microwaves have become a ubiquitous part of our lives, providing quick and easy access to hot meals and snacks. They are essential appliances in most households, and we rely on them for convenience and efficiency. However, every so often, we may notice sparks flying inside while in use, leaving us to wonder if something is wrong. The truth is that this is a common problem that happens to anyone, and it is essential to understand why it happens and what to do about it.

The sparking inside the appliance can be alarming, especially if you don't know what's causing it. Fortunately, there are several reasons why this can happen, ranging from minor to potentially dangerous. Some causes are as simple as a dirty microwave or an old or damaged waveguide, while others are more serious, such as a malfunctioning magnetron or the use of metal objects.

Whatever the reason, it's important to understand why your microwave spark inside and how to prevent it from happening again. In this article, we'll explore the various reasons for the issue and provide some tips on avoiding it. So, grab a snack and let's get started!

10 Reasons Why Your Microwave May Be Sparking Inside

  1. Metal objects: Metal objects such as aluminum foil, metal containers, and utensils cause sparking by reflecting the microwaves to the magnetron, where they cause electrical arcing.
  2. Damaged waveguide cover: The waveguide cover is a metal panel inside that covers the waveguide. If it is damaged, moisture can get in, causing sparking.
  3. Food debris: Food debris or grease buildup accumulates inside and causes electrical arcing.
  4. Wet food: Wet food or food with high water content is also a source of sparking due to how microwaves interact with water molecules.
  5. Damaged magnetron: The magnetron is the component that generates microwaves. If it is damaged, it causes arcing and sparking inside.
  6. Overheating: Overheating causes components inside to expand and contract, leading to cracking or other damage that can source sparking.
  7. Dirty interior: A dirty interior causes food debris and other contaminants to build up, leading to sparks inside.
  8. Damaged turntable: If the turntable is damaged or not functioning correctly, it causes the food to move around inside and come into contact with the walls or other components, leading to sparking.
  9. Loose or damaged wire connections: Loose or damaged wire connections inside can cause electrical arcing and sparking.
  10. Power fluctuations: Power fluctuations or surges cause sparking inside and electrical arcing.

If you believe your microwave is sparking for the above reasons, it's best to have it serviced by a qualified technician. It will help ensure that your appliance is safe and that any potential problems are properly addressed.
