How To Fix Microwave Sparking for $3 - Broken Microwave

Short and easy to follow video on how to fix microwave sparking. This can occur when the waveguide gets dirty overt time and needs to be replaced. Waveguides are readily available on Amazon and eBay but are specific for your model of microwave.
Be sure to search for your specific waveguide size for your specific microwave model.
Available on Amazon - amzn.to/3bg6VzN
It is important to routinely clean your microwave oven as well as clean the waveguide cover. Otherwise, it can get dirty and cause arching or sparking inside your microwave which can be dangerous and potentially start a fire.
This microwave sparking fix only costs about three or four dollars and prevents you from having to buy another microwave. You probably do not have a broken microwave. You just need to replace the waveguide.

My son’s built in microwave began sparking. He’s not very technologically adventurous so he called a repair service. The repair man said it was a lost cause, would cost 500 tp $700 to replace. I found your video and sent it to my son. For 5 bucks he got 5 pieces of wave guide material, one of which he trimmed with a utility knife and now his microwave is spark-free. Thanks! And no thanks to the crooked repairman who preys on the unknowing public

[@JMGENTERPRISES]

That is great! Good for him! Glad I could save you some hassle and money!

[@jsenear]

Thanks. I used your video as a reference. My Microwave started sparking really badly. Because of your video, I looked at my wave guard and it looked like yours. Maybe even worse. I got a pack of universal ones from Amazon. I could not reference a specific one to my Emerson Microwave but I'm glad I couldn't. The universal ones are cheaper. It so happened the new ones were the exact same size as the one that came out of my Microwave. Took me one minute to install the new one and my unit works like new again. Thanks. You saved me from buying a new microwave.

Thanks for this video! I couldn't figure out why the microwave suddenly started misbehaving in this way. I replaced the waveguide and seems to be good to go again. For those reading this, I got a generic waveguide because my part store didn't carry Sharp products. It's just over-sized and only cost $2.50. I traced the exisiting one it and carefully cut it out. Seems to work! Thanks!

My microwave made alarming noises and sparks flew, it was really unnerving. After cleaning it thoroughly, nothing changed so I was about to reluctantly give up and buy a new one when I found your video. I took this "wave guide" thing out, cleaned it and put it back and in less than 20 seconds, my microwave was fixed and working fine again and it cost me precisely nothing. Thanks JMG, fine work sir.

Now remember even if your quick fix doesn't last very long all you need do is purchase a new one for your model microwave or cut one to fit. That will be a good as new fix. They are around $5 to $10 for a new one.

Ordered a replacement because ours was so charred it actually had a hole burned in it. The waveguide covers (pack of 5!) came in a couple days and cost about $6. Thanks for this video!

You should never operate a microwave without anything inside it. Without a load (something to heat up) the microwaves can actually end up bouncing around and going back to the magnatron, stressing it and reducing its lifespan. It can also cause the glass microwave turntable/plate to heat up very quickly to dangerous temperatures. If you're going to test a microwave like this, put a bowl of water in the microwave with a toothpick (or other nonmetallic object) in the water to prevent superheating. This will absorb the microwaves so they don't damage the magnatron or turntable

[@JMGENTERPRISES]

Good to know! I didn't realize.
