Title: LG Microwave LMHM2017ST: Is It Sparking or Arcing?
Are you experiencing sparks or arcing in your LG Microwave LMHM2017ST? Don’t fret! We understand how frustrating it can be when your microwave starts behaving unexpectedly. In this article, we will delve into the reasons behind sparking and arcing, provide troubleshooting tips, and guide you on how to resolve the issue. So, let’s dive right in and get your microwave back to its sparkling best!
Understanding Sparking and Arcing:
Before we jump into troubleshooting, let’s first understand what sparking and arcing actually mean in the context of a microwave. Sparking refers to the sudden appearance of small flashes of light or sparks inside the microwave cavity during operation. On the other hand, arcing occurs when electrical current jumps between two points, causing a visible discharge or arc. Both sparking and arcing are potential safety hazards and should be addressed promptly.
1. Safety First: Unplug the Microwave
The first step in troubleshooting any microwave issue is to ensure your safety. Before attempting any fixes, unplug the microwave from the power source. This will eliminate the risk of electric shock and allow you to work on the appliance without any concerns.
2. Clean the Microwave Interior
Sparking or arcing can often be caused by food debris or grease buildup inside the microwave. Over time, these particles can accumulate and create a conductive path for electricity, leading to sparks. To address this, carefully remove the turntable, roller ring, and any other removable parts. Clean them thoroughly with warm soapy water, ensuring there is no residue left behind. Wipe the interior of the microwave with a damp cloth, paying special attention to the ceiling, walls, and floor.
3. Inspect the Waveguide Cover
The waveguide cover is a small panel made of mica or plastic that protects the microwave’s magnetron. If this cover is damaged, it can cause sparks or arcing. Carefully remove the waveguide cover and inspect it for any signs of burning, charring, or cracks. If you notice any damage, replace the cover with a new one specifically designed for your LG Microwave LMHM2017ST.
4. Check for Metal Objects
Metal objects should never be placed inside a microwave as they can cause sparks and arcing. Double-check the interior of your microwave for any forgotten utensils, aluminum foil, or metal containers. Even a small piece of foil can lead to dangerous arcing. Remove any metal objects you find and ensure the microwave is free from any potential hazards.
5. Examine the Stirrer Blade
The stirrer blade is responsible for distributing the microwave energy evenly throughout the cavity. If the blade is damaged, it can cause sparks or arcing. Carefully remove the stirrer cover and inspect the blade for any signs of wear, cracks, or misalignment. If necessary, replace the stirrer blade with a new one compatible with your LG Microwave LMHM2017ST.
6. Test the High Voltage Diode and Capacitor
The high voltage diode and capacitor work together to convert the electrical current into microwave energy. If either of these components is faulty, it can lead to sparking or arcing. To test them, you will need a multimeter and some basic electrical knowledge. If you are not confident in performing this test yourself, it is best to seek professional assistance.
7. Contact LG Customer Support
If you have followed all the troubleshooting steps and are still experiencing sparking or arcing, it is advisable to contact LG customer support. They have a team of experts who can provide further guidance and assistance. Remember to provide them with all the necessary information about your LG Microwave LMHM2017ST, including the model number and a detailed description of the issue.
Conclusion:
Sparking or arcing in your LG Microwave LMHM2017ST can be a cause for concern, but with the right troubleshooting steps, you can resolve the issue and ensure the safe operation of your appliance. Remember to prioritize safety, clean the interior regularly, inspect the waveguide cover, remove any metal objects, examine the stirrer blade, and test the high voltage diode and capacitor if necessary. If all else fails, reach out to LG customer support for professional assistance. By following these steps, you’ll soon have your microwave back to its normal, spark-free operation. Happy microwaving!
