Most likely culprit is the high voltage rectifier. These are epoxy encased, and do emit a pretty good odor when they short.

Yes it is definitely the magnetron and yes you could change it your self if you are good with electronics and tools (considering that the MAGNETRON DRIVER CIRCUIT is OK) but it is normally cheaper to buy a new microwave oven

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.

Microwave not heating and giving burnt plastic smell

STOP USING IT!! UNPLUG IT!! Microwaves are inexpensive now. It will cost you more than a new one costs, to get it fixed.

it sounds to me like the magnetron is shot in it. this is the part that creates the heat. not worth repairing on a 10 year old unit. Sorry.

Microwave not heating food and is making loud noise.

You have burned out the magnatron (heating element) which is common on GE microwaves. most service companies will charge about 200-250 to replace it

GE Spacemaker XL1800(JVM1850CF001) - Loud Humming noise

You either have a bad magnetron tube (5 or 10 year parts warranty item through GE Factory Service 1-800-432-2737 or www.geappliances.com) or a shorted high voltage rectifier. I think the light being out is a secondary problem.

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!
