Microwave Burning Smell / Burnt Plastic Smell Repair

Repair Melted Wire

[@cryosapion]

Just opened my microwave to see if I had the same problem and sure enough i did. You just saved me a lot of money. The only thing different I did was brake the plastic piece and scraped all the brunt plastic, because I didn't have a new connector, but all in all working great.

[@christophercid8027]

For the people who ask for the part name, these plastic part for join cables it's an isolated terminal or you can find as ferrule.

My wife mentioned to me about her microwave had a melting plastic smell Everytime she used it. Knowing she uses it a lot while I'm at work, I decided to trash it, even though it is only one year old. I searched it out on KZbin, saw your video and thought, WHY NOT? I figured if nothing else, I'd collect a couple of magnets. Opened it up and what was staring me in the face but TWO terminals with the plastic melting off. 30 minutes later she was microwaving the dogs some hotdogs. You saved me $100.00. Thanks man.

Awesome! Glad to hear. That's what it is all about. Humans helping humans.

Twenty years ago I used to work for a retail maintenance company who sent many of us on a microwave repair course for a particular make of commercial microwave. The first thing they taught us after disconnecting the mains and taking off the cover was to discharge the capacitor to avoid an electric shock in case it was accidentally touched. Some of the older guys just used to use a long insulated screwdriver to connect the terminals to the body whilst plugged in to the 3 pin power socket which wasn’t switched on. Sometimes they would connect the body to another piece of catering equipment using a long lead with crocodile clips with a known good earth, then use the screwdriver.

[@raymondromero2840]

You are correct. I am certified in commercial heating and cooling. So capacitor discharge is a good practice when dealing with high volts like AC or microwave. I just didn't on this video because I wasn't messing with anything over 12v. If I was fooling with the electromagnet porting that actually does the heating would I definitely have shown the discharge of the capacitor. I just needed to make a quick vid to help others. Plus I let them know I am not a pro, like you. I only have 2 instances of experience. However I do appreciate you mentioning this. I will add in a discharge in any future vids. Always better to be safe than sorry. Plus it's just makes good practice. Thanks again brother. God bless

[@poetfederico]

And how do I discharge the capacitor?

[@bluesrockslide9511]

@@poetfederico google how to discharge a microwave capacitor safely with a resistor. I think it may be a 2K Ohm resistor. Using a screwdriver can cause a spark. If you’re not familiar with this type of work I wouldn’t attempt it, a nasty injury or worse may result.

Thanks you saved the day man

[@raymondromero2840]

No problem, glad to help.

[@Mr.P001]

Please remember to state the safety measures. I know it's obvious but things like disconnecting from the mains needs to be mentioned to cover you and any of your viewers. Also best to include a disclaimer to protect yourself.

[@raymondromero2840]

Thank you

Thanks for the vid, saved us from having to buy a new micro

thank you so much .. GOD bless you

No problem brother. That's what it is all about. Humans helping humans.

[@Charlie-kw9jk]

Oh dude GTFO! I need to check out an over the range microwave today and I was told it was humming and there is a burning smell. If this is the same issue I owe you man! Liked and subbed either way bro!

[@savanna.romero]

Good job dad

[@RazaKhan-le4ry]

Bahut use full video thank you sir

[@beamarlo3962]

Ill ask a family member to help me with this so thank you for your video. I keep thinking its something small like this and they want to charge me over $100 just to look at it, plus another $300 to fix it. Why can't we find an honest handyman to help us lonely women if it's so simple and cheap...

[@mpa324]

I dont know much about microwaves either ,but i know they have high voltage capacitors that still hold 1000s of volts even when unplugged, discharge them first before doing anything.

[@mohvlogs8310]

Hey great video do you know what that piece (Blue) is called its the one you are replacing please ??

[@raymondromero2840]

The blue piece that I put on is called a electrical quick disconnect receptacle

[@raymondromero2840]

I get packs of them at Wal-Mart for like 3 dollars.

[@mohvlogs8310]

@@raymondromero2840 Awsome thanks much

[@richardrampersad1830]

Hey did you ever find out what was causing it to burn n melt in the first place? The same thing is happening to mine but if the problem is serious then i'll jus buy one. Dont want anything happening to the wifey or my baby when i on a 24hr shift.

[@daylannaidoo1449]

You should discharge the cap before doing anything

[@ThaHandyman1212]

Mine had a smell of burnt and no heat. I think because I kept on using it continuously for like 3 min each time one day and it over heated. Lesson learned

[@raymondromero2840]

Oh dang that is crazy. Good thing nothing's arched out and caused fire. Yeah if some of the connections loose continuity not everything will work properly.

[@markuse3472]

Hi. Is it still working as before the burned piece?

[@raymondromero2840]

Oh yeah it is still going strong, as if it never happened.

[@markuse3472]

@@raymondromero2840 Good for you. Unfortunately I don't have tools and I needed to use a microwave so I had to go buy a new one.

[@henryovenshire1278]

That burned connecter was for both wires

[@raymondromero2840]

Yes the two wires were in the burnt/melted connector. It may be different for your microwave, not all are wired the exact same. Hope this helps.

[@kanitoneko]

What’s the name of that tiny blue connector thing?

[@raymondromero2840]

It's a butt connector. You can purchase them at Walmart, auto parts stores, or hardware stores like lowes.

[@MrBeblis]

You need to always find out the source of the problem, A connector doesn't just burn unless there is bigger problem or a short elsewhere.

[@raymondromero2840]

100 percent correct, I agree. I am a diesel tech and I am well aware of electrical failures and back routing. However I just wanted a quick fix. Also the connector was just melting the surrounding plastic the connector it's self was fine. Thanks though for the heads up. I will probably do a more in-depth trouble shooting video Traci g wire and running the schematic if the microwave brakes or something.

[@jp040759]

@@raymondromero2840 I would say the factory crimp was crap and age caused corrosion and that cause eventual poor connection that generated all the heat to melt the plastic. Steam from cooking probably accelerated the corrosion. You might consider redoing the connector on the other side of the transformer also. HAPPY NEW YEAR

[@acechesser]

3 years later, does your microwave still works ?

[@raymondromero2840]

Yes it does, but this winter we moved it to my "man cave" the garage so it has gott much less use since January however it works fine when is use it every weekend or night's I play pool

[@acechesser]

@@raymondromero2840 Thanks a lot, the video is very useful!

[@TheDanlarrabee]

Is it still working? How long did it last?

[@raymondromero2840]

Still working hasn't messed up since.

[@TheDanlarrabee]

@@raymondromero2840 thanks, you probably saved me a couple hundred. I've got the same burnt wires. I'm not an electronics expert but looking at the wireing digram in my oven... I think what happed is the thermal cut out tripped and the high voltage was dumped through it which burnt the cut out.

[@raymondromero2840]

@@TheDanlarrabee yeah I'm no expert either, but I keep trying to duplicate the issue so that I could get to the root of the cause. I was able to find that when I put it on defrost 15 min 3 times back to back the high voltage magnetic (HVM) box would begin to get very hot 96+ degrees. And the wire where the plastic melted was at 121+ degrees. I mean I don't use defrost for 45 mi. Very often so it not a problem and I removed the plastic so it won't smell. But I guess if necessary I can replace the HVM to solve the issue for good.

[@raymondromero2840]

Hey but glad to hear it helped you out. Thanks for watching.

[@meredith669]

How does "one of these" calls?

[@raymondromero2840]

I am not sure as to what you are referring to.

[@hermanocampeon6806]

My microwave just smoke just now... And luckily... It smoked because of the plastic container was not suitable for microwave😵😵😵 save my money🤣

Thank you bro👍

[@raymondromero2840]

Yeah man for sure it's about saving money so you have more for everything else
