Assuming your inside light and turntable come on when you try to microwave, with the symptoms you have, I would most strongly suspect a shorted high voltage rectifier diode or a bad magnetron, or a loose and possibly corroded connection on the magnetron's terminal.

The diode is a fairly cheap fix, and the mag will cost more.

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

There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

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

Here are some links you or someone you know can use for test help, but read their safety warnings first:

(if it's not shorted or burned, it's probably okay)

Burning smell and loud grinding noise


If that grinding noise sounds a little like gargling into a coffee cup, that's a defective magnetron.

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.

KitchenAid KHHS179lss, fried magnitron?


If your magnetron was shorted, the unit would not heat at all.

The sound of a shorted magnetron is usually a loud hum-- but no or very little smell and no smoke.

Components in the High Voltage section -capacitor, diode- give problems if they short out.
