Rotu is right - it certainly could be crud on the waveguide vcover or waveguide. If not, it might very well be be a bad magnetron. My understanding is that GE had a run of bad magnetrons and/or other problems in the high voltage section, but I don't know if they publicly acknowledged it. If it's not a dirty waveguide problem, I would contact GE or an authorized servicer. If you don't have a manual, you can download it here: http://www.geappliances.com/service_and_support/literature/

SOURCE: Microwave makes a loud noise while using.

After you turn it on, it's a loud noise like it's coming from the fan, but other then that it works wonderfully.

SOURCE: Microwave won't heat/Makes buzzing noise.

The symptoms you are describing are typical of a magnetron that has gone bad. Continuing to attempt to use the oven in its current condition can cause further damage. So, I would recommend not using it. Microwave ovens are considered dangerous and repairs should not be attempted by anyone that is not electronic saavy. The High Voltage Network inside the oven has voltage potentials of 14,000 volts and higher. If you feel this is something you wish to attempt, the Magnetron part number is 1156751 and costs approx. $158. Keep in mind, if the magnetron has been arcing and making a burning smell you may have burned the protective coating that lines the walls of the waveguide. If the waveguide is damaged it is not repairable. I do not know if this is a replaceable item on your model microwave. Double check your warranty information and/or owner's manual. In many cases the magnetron is warranted for several years beyond the limited warranty that comes with most appliances. Post back with comments and let me know if you want me to assist you further. In addition, if you provide me with your EXACT model number (located along the door opening) I can narrow down parts a little better. I know this all sounds discouraging, but I do hope I have been able to help you.

SOURCE: Microwave makes loud noise and does not heat. Smell of light burning

Chances are you have a bad magnetron.

If it's within the magnetron portion of the warranty (usually 5-9 years) but out of the original full warranty (usually 1 year), then your manufacturer will cover the part cost, but not the cost to visit you or the labor charge to do the work.

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

You can usually find helpful exploded view diagrams and order parts by entering your full model number here.

There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.

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

SOURCE: My GE spacemaker microwave won't heat and makes an unusual sound

I have the same problem on my oven- model JVM1640WB and called an appliance repairman who is honest and reliable (I've used him before). He said the problem is with the electrode, to fix it is roughly $300. He recommended buying a new microwave rather than fixing it.

Hi my oven suddenly started making loud weird noises and now does not heat any food. I smell smoke. What might be wrong?


Seems to me that your magnetron is a goner, check also the antenna shield, cover inside the oven cavity and replace both, you may need to clean and repaint burn surfaces inside oven cavity.

We were using the microwave the other night and it started making a loud noise like the fan was running (although the fan was not). We let it sit for awhile and try to use it again but the noise came...


The loud noise and no heat means that the magnetron has failed. It the part that generates the microwaves that heat the food. When it fails it shorts out, causing the transformer to heat up. That is what was causing the burning smell. The cost of a replacement magnetron is around $130-150 range so it may not make sense to have it fixed.

GE JVM1650 Microwave Making Loud Noise


hello Frank. Sorry to tell you that the magnetron is going bad and making that terrible noise. Since the inside of a microwave, even unplugged has up to 2000 residual and deadly volts of electricity I recommend either calling a pro or replacing the unit.

Makes load noise and wont heat anything


I would first suspect a shorted high voltage rectifier diode or possibly a defective magnetron.

If the noise is just a loud buzz, I would suspect the diode. If it has more of a hollow sound - like someone gurgling into a coffee cup - then I would suspect the magnetron.

Here are some links you or a friend can use for test help, but PLEASE read their safety warnings first:
