So, anyways....I had some sweet potatoes we were reheating....I noticed they weren't heating well, and walked away after putting them on for another minute. Then I smelled a burning smell, and immediately the microwave readout went dead, no lights, no power, nothing. I thought that since perhaps there was a bit of a burning smell it most likely isn't the magnatron....going to call a service guy out tomorrow if it's worth it....hoping maybe it's just a diode or something? What could of that electrical burning smell have been? I'm hoping not magnetron since they are so expensive?
First check your electrical panel breaker before calling for service.

Sounds like the problem is in the high voltage. Most common would be magnatron, capacitor and diode. For safety reasons this should be checked by a professional. Look in your owners manual because some high voltage parts have a longer warranty than 1 yr.
SOURCE: burning odor, no heat
A burning smell along with a different sound (growl) USUALLY indicates a breakdown in the High Voltage Side. This is not a direct short (short circuit) or the line fuse would have blown shutting everything down. The High Voltage Side is made up of-- The Secondary ,or High Voltage Side of The High Voltage Transformer, A High Voltage Diode, A High Voltage Capacitor, and The Magnetron. If The High Voltage Transformer is the problem it will smell like a florescent light ballast burning, and will smell each time you turn on the MW. A HV Diode burns and opens, thus no more smell. A HV Capacitor usually does not burn nor does the Magnetron. There is no Cheap-Fix unless you can see that the HV Diode is burned into and you can get to it to replace. CAUTION: Always unplug from power before attempting to repair. NOTE: If you replace a Diode make sure it goes back in the same direction it came out. Yes there is a front and back.

Thanks for making your post very detailed and including the model number. That really helps! :)
With the symptoms you
have, I would most strongly suspect a shorted high voltage rectifier
diode or a bad magnetron.
The diode is a fairly
easy & cheap do-it-yourself 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.
Here are some links you
or someone you know can use for test help, but read their safety
warnings first:

probably okay)

SOURCE: My GE spacemaker microwave won't heat and makes an unusual sound
I have the same problem on my oven- model JVM1640WB and called an appliance repairman who is honest and reliable (I've used him before). He said the problem is with the electrode, to fix it is roughly $300. He recommended buying a new microwave rather than fixing it.
SOURCE: MICROWAVE IS NOT HEATING
HI, the actual device that produces the heat is damaged or faulty. this device is called the Magnetron. you will need to replace this part in order to restore the heating ability of this microwave oven.
Please rate and have a great day:)
