Chances are you have a bad magnetron.

If it's within the magnetron portion of the warranty (usually 5-9 years) but out of the original full warranty (usually 1 year), then your manufacturer will cover the part cost, but not the cost to visit you or the labor charge to do the work.

If you or someone you know decide to look into it, we have critical safety information, info on door switch diagnosis and replacement, and disassembly information at our site, and our link is at our listing here on FixYa.

You can usually find helpful exploded view diagrams and order parts by entering your full model number here.

There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.

It may be a shorted high voltage diode.

Since it's less than one year old, it would be fully covered under warranty. I'd suggest contacting the manufacturer to get it fixed free.

I have a maytag model mmv1164ws when you turn it on makes a buzzing and smells like something burning!


Something is burning, there are high voltage parts in a microwave oven and they wear out. You probably need a new diode. Part number WPW10492276 google it

Hi my oven suddenly started making loud weird noises and now does not heat any food. I smell smoke. What might be wrong?


Seems to me that your magnetron is a goner, check also the antenna shield, cover inside the oven cavity and replace both, you may need to clean and repaint burn surfaces inside oven cavity.

Microwave smell like burning rubber


Good Afternoon Friend,

I understand that you are receiving a burning rubber smell from your Frigidaire microwave. I also see that your appliance will run for a couple of seconds, and then you hear a weird noise, followed by a burning rubber smell. I suggest contacting your local authorized technician, especially when dealing with your microwave. They will be able to diagnose your appliance and determine what is causing that sound as well as the burning rubber smell. Hope this is helpful.

-Best Regards-

We were using the microwave the other night and it started making a loud noise like the fan was running (although the fan was not). We let it sit for awhile and try to use it again but the noise came...


The loud noise and no heat means that the magnetron has failed. It the part that generates the microwaves that heat the food. When it fails it shorts out, causing the transformer to heat up. That is what was causing the burning smell. The cost of a replacement magnetron is around $130-150 range so it may not make sense to have it fixed.

My Kenmore 721.626222 which I have had about 6 years, runs but does not heat. There is also a strange smell - something like a burning smell.


When the oven does not heat, the problem is usually due to the magnetron failing. It the part that generates the microwaves that heat the food. It fails by shorting out causing a loud buzzing noise. The burning smell is the being magnetron overloaded due to the short. It not worth fixing since the replacement cost of a magnetron is close to the price of a new oven. Sorry.

Our Sharp microwave oven turns on, makes a loud humming noise, starts to smell like something is burning, but doesn't heat. Well, actually, we don't think it heats, we're too scared to let it run because...


Normal 0 MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman"; mso-fareast-font-family:"Times New Roman";} This can be caused by grease etc. inside the oven and on the wave guide which is the paper like thing in the oven. If you can remove it look for burnt areas which may can be scraped off or you may need to replace it. An appliance parts store usually has the material you can cut to fit you own.

Is there any burning smell after you try to heat with the microwave?

In most cases of no heat with a loud noise, it's a bad high voltage diode or magnetron.

Posting that video may help if you get the sound clearly.

The noise is coming from the high-voltage transformer being overloaded by something shorting it out. Either the magnatron or the high-voltage capacitor and diode. Replace the capacitor and diode then if still not working, replace the magnatron. Its only affordable if you do it yourself - buy the part on EBAY - lookup "universal magnatron"
Hope ya fix it!
