A Guide to Addressing Microwave Oven Sparking Inside – Causes and Solutions

**Introduction:**

Discovering sparks inside your microwave oven can be a cause for concern and confusion. In this informative guide, we’ll delve into the potential reasons behind “microwave oven sparking inside” and provide practical solutions to ensure your appliance operates safely and efficiently.

**Common Causes of Microwave Oven Sparking Inside:**

1. **Metal or Metallic Objects:**

   – **Explanation:** Placing metal containers, utensils, or aluminum foil inside the microwave can lead to sparks as these materials reflect and trap microwave energy.

   – **Solution:** Avoid using metal items in the microwave. Opt for microwave-safe containers made of glass, ceramics, or certain plastics.

2. **Damaged Waveguide Cover:**

   – **Explanation:** The waveguide cover, often made of mica, protects the microwave’s interior. Damage or wear to this cover can result in sparking.

   – **Solution:** Inspect the waveguide cover for any signs of damage, and replace it if necessary. Consult your microwave’s user manual for guidance.

3. **Food Debris or Grease:**

   – **Explanation:** Residue from food or grease can accumulate on the interior surfaces of the microwave, leading to sparking during operation.

   – **Solution:** Regularly clean the interior of your microwave with a mild detergent and water. Pay special attention to the turntable and walls.

4. **Faulty or Damaged Stirrer:**

   – **Explanation:** Microwaves with stirrers distribute energy evenly. A malfunctioning or damaged stirrer can cause uneven energy dispersion and sparking.

   – **Solution:** If your microwave has a stirrer, check for any visible damage and consult the user manual for instructions on repair or replacement.
