What should I do if my microwave is sparking?
Greetings, fellow do-it-yourself warriors! Have you ever been on popcorn making duty, turned your microwave on, and suddenly it's contesting your Christmas light show? The microwave is sparking, and it's not as festive as you originally thought. As your friendly neighborhood repairman, I'm here to give you the 411 on how to handle this electrifying problem.
Why is My Microwave Sparking, Anyways?
Before we can stop the fireworks, we need to know why the sparks are there in the first place. Microwave sparks, also lovingly known as "arc", usually occur because of exposed metal. Microwaves bounce their energy off their metal interiors. But if the waves hit exposed, non-treated metal (like the tiny piece your kid probably left inside), they reflect off it and cause sparks.
So, your microwave might be sparking because of a rogue piece of aluminum foil, a metal-rimmed bowl, or even a twist tie left by the rotating plate. Heck, even a broken rack support or a damaged paint job inside the microwave can cause arcing.
Step 1: Keep Calm and Remember Safety First
If your microwave is throwing a spark party, turn it off immediately. Unplug it from the electric source. Safety always comes first, even among us DIY enthusiasts. Now, take a deep breath and relax, because we're going to tackle this issue step by step.
Step 2: Conduct a Microwave Investigation
Put on your detective hat and start inspecting the inside of your microwave. Look for scraps of metal or foil. Also, check if your rack support is in good condition or if the paint has chipped anywhere. Take out the rotating plate and ring, and see if they're undamaged.
Step 3: Clean the Culprit
If you do find a foreign object, just remove it. If the sparking was due to a splatter of lasagna sauce or a pizza slice, clean your microwave thoroughly. A soft cloth, a bit of soap, and elbow grease will suffice for this task.
Bonus tip: for stubborn stains, mix a spoonful of vinegar with a cup of water, heat it for 3-4 minutes, and then let it steam inside the microwave for 15 minutes. The dirt and grime will come off easier.
Step 4: Consult the Experts
If the sparking continues despite your best DIY efforts, it's advisable to consult with a certified professional. Continual sparking could indicate severe issues like a faulty high voltage diode or a defective Magnetron. It's best to let the experts handle this, as it involves dealing with high voltage components.
Step 5: Know when to Let Go
Sometimes, the most budget-friendly and practical solution is to buy a new microwave. If the cost of repairs exceeds a significant portion of the cost of a new microwave, it may be a wise investment decision to replace the old one.
Be Proactive: Routine Inspections
The golden rule for ensuring the longevity of your microwave is to regularly perform checks for any foreign objects or food splatter. Most importantly, educate everyone in your home about what can and can't go into the microwave. A little precaution can save you from unexpected sparking adventures!
