GE microwave is not heating food

GE microwave - spacermaker over the stove model JVM1650BB00

My microwave works with the exception of heating. I was attempting to heat so leftovers when I heard a crackle sound after I entered the cooking code on the touch panel. Do you know if there are any reports of this model having problems being over the stove? I've noticed that in the last few years, my new microwaves keep going out. Could it be possible that the moisture from cooking causes a short in the touch panel? How would I diagnose the problem? I know that there are repair shops, but I am not as confident that they will be able to give me an unbiased answer. We are weighing the possibility of just replacing it all together instead of the hassle of repairing. I would like to save 300-400 dollars though.

Re: GE microwave is not heating food

That crackle is usually a failed high-voltage rectifier diode. It's possible that the magnetron is failing or failed, too, but I would suspect the diode first.

Generally, the most common causes of a failure to heat are:

- bad door switches or door switch mounts
- loose connection at the magnetron
- problem or loose connection on the control unit circuit board
- bad magnetron or other high voltage part

It's always recommended that you have the hood fan on when cooking on the stove to prevent moisture from entering the controls of the microwave.

Also, I tell my customers to be sure no one ever sprays cleaner directly on the keypad.

But I don't think those are factors in your case.

If you or a friend decide to look into it, we have critical safety information, info on door switch diagnosis and replacement, and
disassembly information at our site, linked here on Fixya:

Re: GE microwave is not heating food

I have a GE J ES1133WN4 space saver over the stove microwave. It all of a sudden stopped heating food. I read in previous posts that people heard a noise. That did not happen in my case. Everything else is fine. Since there was no noise would that eliminate some of the problems listed above?

May Spacemaker XL1800 stop heating food. Was working fine. Then just stop

Is this an over the stove type unit? I have had a few problems with my over the range spacesaver. I think the heat from cooking gets up into the microwave and damages it. The steam from me boiling things on the stove had mine quit heating and I purchased a new one. The parts to replace the faulty ones can be quite expensive over $150.00, so its better to purchase a new microwave.

GE microwave model JVM1750DM does everything except heat food. Worked this morning fine.

Chances are the magnetron has failed, "heats food" the other possibility is the high voltage capacitor and diode. Repairs will approach the cost of a new microwave oven.

It does everything except heatinig up food. Model # JVM 3660 SD 001

The magnetron is not working. This open it and check to see if it has a blown fuse. Some microwave would have seperate fuse for the heating power. If fuse is good. You may be able to get a used magnetron from another microwave. Somtimes pawn shops would sell microwave for 5 or ten dollars just because it doesnt have a turnplate inside.

The exhaust fan works, the light below the microwave that shines on the stove top works. It appears to be functioning properly except that it won't heat up food. The GE Spacemaker Model JVM131001 is...

I'm all for fixing appliances but in your case I would suggest replacement. After 24 years of service the magnetron is probably only putting out half of its rated wattage. It could also be one of the reasons of the no heat condition.

Everything works except heat

Sounds like you've had a failure in the microwave portion of the unit.

Microwave not heating problems when the timer/controller board appears to function properly, are related to the following components -

1) Diode
2) Capacitor
3) Transformer
4) Magnetron
