Title: Frigidaire Microwave FGMV174KFC: When Sparks Fly

Have you ever experienced the unsettling sight of sparks or arcing inside your Frigidaire Microwave FGMV174KFC? It can be quite alarming, but fear not! In this article, we will delve into the reasons behind this phenomenon and provide you with some practical solutions to address the issue. So, let’s get started and shed some light on why your microwave might be sparking or arcing.

1. Understanding the Basics of Microwave Functionality

To comprehend why sparks or arcing occur in your Frigidaire Microwave FGMV174KFC, it’s essential to grasp the basics of how microwaves work. Microwaves generate electromagnetic waves that heat food by exciting water molecules within it. This process is facilitated by a high-voltage power supply and a magnetron, which converts electrical energy into microwave radiation.

2. Potential Causes of Sparks or Arcing

a. Improperly Placed Utensils:
One common cause of sparking or arcing is the presence of metallic objects inside the microwave while it’s operating. Metallic utensils, aluminum foil, or even dishes with metallic accents can cause electrical discharge, resulting in sparks. Always ensure that you use microwave-safe containers and avoid placing any metal objects inside.

b. Damaged Waveguide Cover:
The waveguide cover is a protective component that prevents food particles and moisture from entering the microwave’s internal components. If this cover is damaged or has food residue on it, it can lead to arcing. Regularly inspect and clean the waveguide cover to avoid this issue.

c. Worn-out Stirrer Fan:
The stirrer fan is responsible for distributing microwave energy evenly throughout the cooking chamber. If the fan is worn-out or malfunctioning, it can cause irregular energy distribution, leading to sparks or arcing. In such cases, contacting a professional technician for repair or replacement is recommended.

d. Burnt Food Residue:
Accumulated food residue or grease on the walls, ceiling, or floor of the microwave can cause sparks when heated. This residue can act as a conductor, resulting in arcing. Regularly clean the interior of your microwave to eliminate any potential causes of sparks.

3. Steps to Address Sparking or Arcing Issues

a. Remove Metallic Objects:
If you notice sparks or arcing, turn off the microwave immediately and remove any metallic objects or containers from inside. This simple step can prevent further damage and potential hazards.

b. Inspect and Clean the Waveguide Cover:
Carefully examine the waveguide cover for any signs of damage or food residue. If you find any issues, clean the cover using a mild detergent and a soft cloth. Replace the cover if it is severely damaged.

c. Check the Stirrer Fan:
To ensure the stirrer fan is functioning correctly, turn on the microwave and observe whether the fan is spinning smoothly. If it’s not, consult a professional technician to repair or replace the fan.

d. Clean the Interior:
Regularly clean the interior of your microwave with a mixture of water and mild detergent. Pay close attention to areas where food residue may accumulate. This practice will help prevent arcing caused by burnt food particles.

4. Safety Precautions

While addressing sparking or arcing issues in your Frigidaire Microwave FGMV174KFC, it’s crucial to prioritize safety. Here are a few precautions to keep in mind:

a. Unplug the Microwave:
Before attempting any maintenance or cleaning, always unplug the microwave from the power source. This step ensures your safety and prevents any accidental electrical shocks.

b. Avoid Harsh Cleaning Agents:
When cleaning the interior or any components of your microwave, refrain from using harsh chemicals or abrasive materials. Stick to mild detergents and soft cloths to avoid damaging the microwave’s surfaces.

c. Consult a Professional:
If you’re uncertain about any repairs or troubleshooting steps, it’s best to consult a professional technician. They have the expertise to handle complex issues and ensure the safety and longevity of your microwave.


Sparks or arcing in your Frigidaire Microwave FGMV174KFC can be concerning, but with the knowledge gained from this article, you can address the issue effectively. Remember to remove metallic objects, inspect the waveguide cover, check the stirrer fan, and regularly clean the interior to prevent sparking or arcing. By following these steps and prioritizing safety, you can enjoy the convenience of your microwave without any unexpected fireworks.
