Question about GE Advantium SCA2000B Microwave Oven

1 Answer

Microwave oven problem

Hi, you gave me info about my GE Advantium SCB2001css03 yesterday (Dec. 16)...including information about the diode, capacitor and fuse. I discharged the capacitor, at least I think I did...nothing happened. The diode looks okay, although I haven't done any tests on it. However, the fuse has black marks on it, but I can't really tell what's happened inside because the glass portion is white with a black stripe on it in the middle. I'll replace this first, it says 250V, 20A. Is there a specific fuse I have to get...or can I just go to a hardware store and get one?

    So, I got a fuse at an appliance service center, put it in, tested the oven and it works! Thanks for your help. However, the guy at the service center seemed to think my problem is an interlock switch before the diode or capacitor. Anyway, it works for now. Thanks.

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:

Or feel free to post back with details. Good luck!

Microwave lights and fans work but the food does not cook

If the microwave sounds normal, but not heating, then the magnetron is bad and needs to be replaced. If it is making a humming noise, then the diode is bad. I recommend that if it is the magnetron, ou also replace the diode.

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.

No power,does not turn on, checked breaker and reset plug

check the interior ceramic fuse they are available at hardware stores, if new fuse blows,suspect h.v. diode,capacitor,or the magnetron tube

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

The microwave is not heating. Light comes on, fan comes on and turntable rotates but nothing gets hot.

either your hi-voltage diode,capacitor or magnetron are defective,if your not electrically savvy,don't open the unit up, by hi-voltage i mean the cap can store up to 2,000volts a.c.appx 18 times whats at your plug in receptacle,if you do tackle it,make sure to completely discharge the cap before attempting any repair...gooid luck and be safe
