Title: LG Microwave LMV1762ST: Is It Sparking or Arcing?

Have you ever experienced the terrifying moment when your microwave starts sparking or arcing? It’s like a mini fireworks show happening inside your kitchen! Don’t worry; you’re not alone. Many people have faced this issue with their LG Microwave LMV1762ST. In this blog post, we will explore the reasons behind sparking or arcing in your microwave and provide you with some practical solutions to fix the problem. So, let’s dive in and unravel the mystery behind those sparks!

Understanding the Basics of Microwaves

Microwaves have become an essential appliance in most kitchens. They work by emitting electromagnetic waves that excite water molecules in food, generating heat and cooking the meal. However, sometimes these waves can cause sparking or arcing, which can be dangerous if left unaddressed.

What Causes Sparking or Arcing in Microwaves?

1. Metal Objects: One of the most common reasons for sparking or arcing in microwaves is the presence of metal objects inside. Metal reflects microwaves and can cause electrical currents to jump, leading to sparks. Avoid using metal utensils, aluminum foil, or any metallic containers when microwaving your food.

2. Damaged Waveguide Cover: The waveguide cover is a protective shield inside the microwave that prevents food particles and moisture from reaching the electrical components. If this cover is damaged or has food residue on it, it can cause arcing. Regularly inspect and clean the waveguide cover to prevent this issue.

How to Fix Sparking or Arcing in Your LG Microwave LMV1762ST

1. Remove Metal Objects: Always double-check your microwave before using it. Remove any metal objects like spoons, forks, or aluminum foil. Even small bits of metal from chipped plates can cause arcing. Remember, safety first!

2. Clean the Waveguide Cover: To clean the waveguide cover, first, unplug your microwave and remove the cover according to the manufacturer’s instructions. Use a mild detergent and warm water to gently clean the cover. Ensure it is completely dry before reattaching it. This simple maintenance step can prevent arcing and extend the lifespan of your microwave.

3. Inspect the Interior: Take a closer look inside your microwave. Look for any signs of damage, such as cracks or burns. If you notice any, it’s best to contact a professional technician to repair or replace the damaged parts. Ignoring these issues can lead to more serious problems down the line.

Additional Tips to Prevent Sparking or Arcing

1. Use Microwave-Safe Cookware: Always choose microwave-safe cookware made of glass, ceramic, or microwave-safe plastic. These materials don’t interfere with the microwaves and minimize the risk of sparking or arcing.

2. Avoid Overheating: Microwaving food for too long or at excessively high power levels can cause overheating, leading to sparks. Follow the recommended cooking times and power levels mentioned in the microwave’s user manual.

3. Keep It Clean: Regularly clean your microwave’s interior, turntable, and door seals to remove any food residue or spills. This will prevent any potential arcing caused by these particles.


Sparking or arcing in your LG Microwave LMV1762ST can be a cause for concern, but with the right knowledge and precautions, you can address and prevent this issue effectively. Remember to remove metal objects, clean the waveguide cover, and inspect your microwave for any damage. By following these steps and incorporating additional preventive measures, you can ensure a safe and hassle-free microwave cooking experience.
