Question about GE Advantium 120 Convection/Microwave Oven

1 Answer

Microwave not heating every time...

I just renovated my kitchen and bought the Advantium 120. Everything seems to work well except the Microwave part. At times it heats well, and other times not at all. This morning, it took me 3 tries to heat my oatmeal. A couple hours later, it heated a cup of water on the first try.

Visually it appears that it is working, lights up, time counts down, etc. but when it says it finished, my food isn't heated.

    That's what the GE guy said when he came out and thought he fixed it. Before he left, he ran the microwave 4 times, and each time it heated up. However, the next day when I went heat some veggies up, the microwave didn't heat at all and hasn't since. The GE guy came out again, but can't figure it out. So he's going to order the panel and try replacing it.

    He hasn't changed the part yet. Should be this week. When he took the panel off, he checked to make sure some connection was getting the proper amp/voltage(??) which it seem to get. He couldn't figure out why it wasn't heating with everything "checking" out ok.
    I'll update later in the week...

    So it turned out to be a problem when the Advantium was manufactured. The magnatron has 4 screws to hold it in place and only 3 were screwed in. GE, at my request, sent another Technician to look at it, and immediately when he took the panel off new what it was and fixed it.

    I must say though, GE has the worst customer service I have encountered. Not only was the technician they sent out to me the first 3 times the worse ever, they provided no help whatsoever in trying to figure out the issue. All they could really say was "I'm sorry this is happening, but there isn't anything we can do". Never buying a GE product again!!!!

    all 3 thermostats pass current and the interlock switches are also good.

You seem to be having a problem with the interlock device. when you close the microwave door it is supposed to hit a series of 3 switches to tell the microwave every thing is safe and able to run. you may want to take the control panel off and make sure those switches are ok. usually out of the 3 switches top and bottom should be open middle should be closed. you could check with the continuity side of your electric meter.

Let me know if you have any questions before rating me.

    the only other thing i would think is one of the other switches. he didnt run it to see if he could duplicate the problem before changing the part?

Our Advantium 120 oven (model # SCA1001KSS 02, Manufactured June 2008)is not working. Began w/ time not coming on when cooking and just a little green microwave light shows while cooking.

Typical of a control microchip failure caused by a power surge. With a microwave as old as yours, it is safest to simply replace the entire oven rather than attempt to fix it, as older magnetrons are likely to fail.

Disconnect it and connect bac to power. check the fuse. If nothing works is either the fuse, the cable or the power supply unit.

Chances are you have a bad secondary / cook relay on the control circuit board. The relay can be replaced. See details here.

Problem with the GE Advantium (model sca1001fss01) Convection / Microwave Oven Everything works except the microwave. It makes a sound like its working, table turns, but does not heat or cook.

sounds like the magnetron. Youll have to have a technician replace it. if you have a warranty just call the company and they should take care of you.

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.
