This is tough to call remotely, but it will almost certainly be the magnetron or high voltage capacitor or (if you're lucky) the high voltage rectifier diode.

If you or a friend decide to work on it, we have *critical* safety, disassembly, and troubleshooting info at our site, and our link is at our listing here on FixYa: http://tinyurl.com/yzjozk

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

G.E. spacemaker microwave stopped heating,made louder than normal sound,smelled odd.


The magnetron has failed, "heats food" to repair the unit will approach the cost of a new microwave oven.

Does not heat, hot or burning wire/plastic smell. Louder noise than noise than normal.


Sounds like you have a bad magnetron. Not much worth replacing in these over-the-range microwaves except the fuse. Repair will cost as much as a new one and the high voltage circuit of a m/w is not somewhere I would recommend a DIYer to mess around in.

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.

Noise while not running


don;t worry;
all you need to do is lubricate the fan bearings with light machine oil and make sure the fan is not hitting anything

Boiling waer under micro wave lots of steam into micro wave, turn on micro wave ,pop noise like glass miro wave comes on louder hum than normal no heat


Q - The microwave display counts down and the inside light is on,  but nothing is heating and the fan is not running.
A - This most commonly is a bad door switch, other possible problems are a faulty relay or solder joint on the power module, but a bad door switch is most common.
 Q - My microwave is running and sounds like it is working but will not heat up anything.
A - Many thing can do this but, common things are....loose high voltage wire.....poor solder joint on board.....magnetron.....power relay.....
Q - The microwave makes a loud "hum or buzz" noise but will not heat up the food?
A - 9 times out of 10 this is usually this is a bad magnetron, the other time is sometimes a bad high voltage diode. See components section.

Louder than normal noise when using and bad 'burning' smell


You need to stop using your microwave if it's burning. This is a common symptom of a blown magnetron. Using it in it's current condition is not only dangerous, but it will further damage other components in the high voltage circuit and/or waveguide. In many circumstances, damaging the waveguide renders a microwave non-repairable. A new magnetron will cost you around $100 if you wish to repair this yourself. NOTE: I would not recommend working in or around the high voltage circuitry unless you absolutely know what you are doing. Do not attempt to take any live voltage measurements or operate the oven with any of the protective covers removed or interlocks defeated. Voltage potentials of over 13,000 volts exist and are potentially dangerous. I hope this helps you.
