Question about GE Microwave Ovens
I have a 10 year old SCA2001FSS Advantium oven that immediately blows the 20A main fuse. Here are some details: - Yesterday I noticed that one of the smaller fans inside would not turn off after using the microwave. It wasn't the main exhaust fan. - Also, the turntable was turning kind of slowly and feebly. Otherwise everything seems to work. But I unplugged it anyway to stop the fan noise. - Later in the day I plugged it back in to microwave something for 7 minutes and walked away. When I came back a while later, the fuse was blown. The food was a little warm like it had run for a minute or so before blowing. - I put a new fuse in. Fuse blew immediately when plugged in. - I removed the control panel/smart board assembly and replaced the fuse. Fuse blew immediately. Any ideas of the problem or next steps to diagnose? Thanks!
Yeah pal, you've not gone deep enough yet. You'll find a power wire bare inside the unit, pull it apart and tape that wire up to stop it from grounding out and blowing the fuse.

Thought I had answered this, but this is usually caused by either a bad door switch, a loose door switch mount, or possibly a problem on the control panel.
Even though a door switch clicks, it may still be bad inside. Its continuity must be checked.
Door switch or mount trouble can be caused by slamming the door or by opening the door while it's cooking without hitting the Stop pad first.
If you someone you know decide to look into it, we have critical information on safety, disassembly and door switches at our site, and our link is at our listing here on FixYa: http://tinyurl.com/yzjozk

There should also be a "mini-manual" hidden inside the unit behind the control panel, which is very helpful when troubleshooting.
If you think the problem is on the control panel, we repair these nationwide by mail for $39.95 postpaid in most cases.

At our Web site, you can get details of our service, plus we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.
This light failure often occurs when a bulb goes out and the filament shorts, or when the bulbs are removed or installed without first unplugging the oven from the power line. Either can cause such a failure on the controller.
Sometimes this will also affect the exhaust fan operation, too. The lights and fan can be inoperable or stuck on too.
Feel free to contact me directly (and please remind me of your full model number) for more information & help.

More than likely the magnetron has failed. This could be for a number of reason. Do you use your microwave to heat wheat packs or warm plates? If so, you may have dried the magnetron out (they use the moisture in whatever you're cooking to heat it, and plates/wheat bags have no moisture).
I'd say a trip to your local Microwave repairer could be in order. It could also be the High Voltage Fuse which has failed. Either way a repairer will be able to tell you!

It sounds like the magnetron may have
either failed or is not being supplied with the extremely high
voltage required to run it.
Make sure the !!!!capacitor is discharged!!!!! before attempting any sort of repair.
Check the door interlock switches first then the high voltage diode with either an AVO model 8 on high resistance range for short circuit, the capacitor can fail and go short circuit, the feed fuse on the primary of the high voltage transformer and then finally, the magnetron is best checked by substitution.
Hope that helps.
