SOURCE: GE SpaceMaker Microwave suddenly stops while heating

I had same problem last week. My GE JVM1650 Spacemaker stopped after a few seconds of heating. Owned 16 months, manufactured Jan 2005. It was the magnetron, which was replaced yesterday. The magnetron has a 10-year warranty, but I had to pay $161.00 for labor by a GE technician. The call-out fee was waived at my request. I don't know what that amount would have been, but I can't believe the $161.00 for what was about 1/2 hour labor once diagnosed. Good Luck!

It sounds like you press STOP two or three times to lock it. Maybe that (or another key) will unlock it.

The lock / unlock procedure will be covered in your owner's manual.

Or you can try a hard reset - unplug it from the wall for one minute, then plug it back in and try again.

If you don't have your manual, you can get one here. (Enter your model number without any spaces)

With the symptoms you have, I would most strongly suspect a shorted high voltage rectifier diode or a bad magnetron, or a loose and possibly corroded connection on the magnetron's terminal.

The diode is a fairly cheap fix, and the mag will cost more.

If you or someone you know decide to look into it, we have critical safety information and disassembly information at our site, and our link is at our listing here on FixYa.

There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

If you don't find yours, or if you want to look at it without disassembling the oven, you can download it here.

Here are some links you or someone you know can use for test help, but read their safety warnings first:

http://www.gallawa.com/microtech/diode.html (if it's not shorted, it's probably okay)

Since it's less than one year old, it should be fully covered under warranty. I'd suggest contacting the manufacturer to get it fixed free.

If for some reason you don't have your owner's manual, I would suggest calling the dealer where you bought it to see if they have a number for Cookworks.

Kenmore microwave model 7210413500 suddenly stopped heating. What are the steps I might take to troubleshoot and diagnose the probelem. Is there another microwave that can replace this model in the s

Model nimber is blocked out for some reason. But dont try to repair a microwave unless you understand how to work with high voltages. The voltages you are dealing with here are lethal. You must discharge the capacitor before any work can be done. Generally only two parts are do most of the failures, the diodes an the large capacitor. If you do not have the proper gear to test leave it alone. The cost to repair is usually runs higher than the cost of a new microwave.

Microwave oven suddenly stopped working, no display,not outlet

Hi, you must check the inside fuse. If is burned out, please consider that something happened, you must check further beyond to find the causes.

Microwave stopped heating

I had the same oven for one and a half years and had the same problem. Had the sears repairman come out and he said the magnetron burned out and needed replacing for $285. It was never under warranty with the warranty that came with oven. I couldn't believe it! We had an independent repairman look at it and he found a design flaw that causes the magnetron to blow. If you replace the matnetron (megnatron?) it will work for awhile, maybe, but then just need to be replaced again. It's cheaper to buy a new microwave. In fact, I got out our old microwave that's over 20 yrs. old and still works--just isn't as fast and as new ovens. Good luck!

Kenmore elite microwave touch screen stopped working

Same thing happened to us. We just came back from Sears, where we bought another. Just for giggles, my wife suggested unplugging the old one and plugging it back in again. It works now. New one's going back to the store.

Microwave suddenly stopped working

Code F3 indicates an open / defective thermistor / temperature sensor. The first suspects when a microwave is not heating would be the door switches, bad connections on the magnetron terminal or bad connections on the control board. If you or a friend decide to work on it, we have *critical* safety, disassembly, and troubleshooting info (as well as a text file which helps in diagnosing and repairing door switch problems) at our site, which is linked at our listing here on FixYa: http://tinyurl.com/yzjozk
