Question about GE Microwave Ovens

1 Answer

Why is my GE Advantium SCA2001 blowing the main fuse?

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.

    Thanks for the response - but why do you think there is a bare power wire to be found?

  • Rigger DeBusk Aug 31, 2014

    Because it's tically blowing the fuse. Only makes sense that it's a dead short/hot wire gouning.

  • Rigger DeBusk Aug 31, 2014

    Yeah,that was hot wire grounding.

    What could cause an undisturbed wire to suddenly short out? Looked around

  • Rigger DeBusk Sep 01, 2014

    No problem Bro. As old as it is, even a wire that's close to the metal framework inside can eventually arc and pop the fuse. Check all res for a black burnt spot on the coating. It's happened to me before.

  • Rigger DeBusk Sep 01, 2014

    Check all wires for burnt spot. My letters are dissappearing somehow.

    ok -i'll look closer!

  • Rigger DeBusk Sep 01, 2014

    Cool. I hope you find the spot. We'll walk through this more if yu don't see any evidence of arcing.

    Found the problem! Turntable motor is fried - prob because I've been microwaving unshucked corn recently without a tray and some of the silk probably snuck down into the motor).

    Matthew Callan Sep 01, 2014

    My fault. Pulled the motor and everything works.

  • Rigger DeBusk Sep 01, 2014

    Wasn't as hard as you thought,huh. Those motors are easy to replace also. I won't run a microwave without one, and I have 4. The press panel just went bad in the one I was using, so I trashed itnd dug out another. No problem, peole give me these things, I fix them and put them in torage for next time needed.

  • Rigger DeBusk Sep 01, 2014

    Oh, I'm happy you found the problem and ook it out of the equasion.

SOURCE: microwave running although not turned on

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

You can find helpful exploded view diagrams and order parts by entering your full model number here: http://tinyurl.com/gv383

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.

We're happy to help and we appreciate your thoughtful rating of our answer.

SOURCE: Fan, turntable, light only work after being temporarily unplugged

We see (and repair) this a lot. The problem is on the control panel, which we regularly repair nationwide by mail for $39.95 postpaid in about a week.

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.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

SOURCE: GE Microwave won't heat or cook - one year old

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!

GE Advantium 120 SCA1000DWW03 blowing 20amp fuse


Our unit was doing the same thing,
took it into the repair shop, they said there was nothing wrong with the unit, replace the main breaker that supplies power to microwave and try again.
Sure enough the breaker became defective, and we never had issues with it before, but now the unit has not had a single problem.

Re: "my GE Advantium SCA2001


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.

Microwave blows fuse in microwave mode grill function ok


It is most likely the capacitor has shorted or the rectifier has shorted. Check with ohmeter, but make sure it is discharged first by shorting the capacitor with a wire.

Need to replace fuse in GE Profile advantium oven


remove outer shell/cover, the fuse will be in a fuse holder about 1" long X 1/8" in diameter and is called a ceramic fuse,take it out,look on ends for current rating go to hardware store they have repl fuses, if the new fuse blows it could be your h.v. diode, capacitor, or the magnetron tube

Microwave oven problem


A fuse blows most often because of an excess of current due to a failed (or failing) component (high voltage cap, transformer, or door interlock switch) or a surge; or due to overheating of the fuse caused by a fuse holder that is too loose.

If replacing the fuse fixes it, then it may have been a fluke surge.

But don't be surprised if it blows again. If so, I would refer you back to my previous solution post here:
