Question about GE XL1800 1100 Watts Microwave Oven
A while ago our XL1800 would run fine, then about a minute or two into the heating cycle would make a loud, electrical buzzing sound kind of like a transformer on a power line shorting out. I replaced the magnetron (GE sent it for free since it was built in 2004), and the same thing happens. They sent another one (miracle!) and now I'm wondering if there's another problem. Any suggestions?
Sedonix is talking about the high voltage capacitor.
When they fail, they usually short, and that will blow the fuse as soon as you hit the Start button.
I doubt it's the cap, but if you want to check that too, see:

The scary noise is coming from the transformer (big heavy steel thing under the magnatron) that steps up the voltage for it. Something is overloading it causing it to have way too big of a magnetic field causing it to vibrate so much it makes noise. Since you have ruled out the magnatron (which almost always is the culprit) it could be the high voltage diode, or high voltage cap (more likely). Replace those two and it should work. Microwaves are nice to work on cause its a simple circuit and they usually give you a schematic pasted on the inside.
