I own a Ge Microwave built in 2001. When I start it there is a loud hum. I suspect this may be the magnetron. Can you verify?

It may be a shorted high voltage rectifier diode or a bad magnetron.

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.

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

(if it's not shorted or burned, it's probably okay)

Loud hum in my ge rc7200


More than likely the Magnetron is bad, causing the transformer to over heat. Or it could just be the transformer going bad. Either way not a good situation. Both are expensive.

My JES636WK01 microwave heats up but it makes a loud humming noise. I suspected the Magnetron and disconnected it. The microwave was then operated and the n oiuse was the same. Do you have any ideas


Disconnect the HV transformer leads from the magnetron and the capacitor. Make sure none of the wires are touching the chasis or other parts. If the loud humming sound is still present, it is the High Voltage transformer making the noise. If the noise goes away, it is the High Voltage Capacitor going bad.

*MAKE SURE TO UNPLUG UNIT BEFORE TOUCHING ANY OF THE HIGH VOLTAGE LEADS! ALSO, DISCHARGE THE CAPACITOR BY SHORTING THE TWO SIDES AGAINST EACH OTHER!

No heat in microwave. Makes loud humming sound when turn on. Model GE Spacemaker JVM166OWBC 04


The humming can be caused by a couple of bad parts. Usually it's the magnetron tube, the microwave source. They often fail by shorting out, and the loud hum from the power supply is what you hear. Another part called the HV diode may also have shorted, but the magnetron is more common.

A bad magnetron can be replaced, but it's a costly part. And microwave service should be left to a professional, because there are dangerous voltages under the cover and a chance of microwave leakage if repairs aren't done correctly. Between the part and labor costs, it might be more economical to replace the oven. Let a qualified servicer give you a repair estimate and then decide.

My microwave is not heating the food. It is built into the walls of my kitchen in my condo/apartment. Can I fix this myself? How?


When the oven is running, does it make a loud buzzing or humming sound? If it does, then the problem is the magnetron, the part that generates the microwaves that heat the food. It not worth fixing since a new magnetron will cost almost as much as a new microwave. Ask your landlord that you need a new microwave oven. Sorry.

I have a 2001 GE Spacemaker #JVM1840CD001 that does not heat anything, but runs. What's wrong and how can I fix it?


If your microwave oven "works" meaning that your display, cooking tray rotates, and the light turns on when you open the door, but does not heat the food, the problem usually is with the magnetron circuit. If you hear a loud hum when you try to heat something in the oven usually means that the magnetron has failed. The replacement magetron is about the same price as a new oven, so you are better off buying a new oven.

You either have a bad magnetron tube (5 or 10 year parts warranty item through GE Factory Service 1-800-432-2737 or www.geappliances.com) or a shorted high voltage rectifier. I think the light being out is a secondary problem.

GE Profile JE1660GB01 magnetron failure?


It pass the resistance tests and still be bad, and I suspect it is.

I would also suggest that you check the high voltage diode to be sure it's not shorted.

If the filament voltage and high voltage are both present at the magnetron terminals, and not loaded down, but there is no heat, then it's the magnetron.

As a pro with over 20 years of expereince, I have always measured the high votlage, but I will never recommend it to a non-professional. Without the right equipment and procedure, you and your equipment can be "fried". No kidding.

Loud humming/no heating


Word has it that many of these models have a defect which causes the microwave energy to be reflected back to the magnetron, causing damage to the magnetron, and eventually damaging the high-voltage diode too. Also, the fuse or the magnetron theral cutout / thermostat can eventually blow, too. There is a replacement magnetron and stirrer kit available. I would definitely call the GE Answer Center at 800-626-2005 about this. It's not considered a recall, but a "campaign". They may pick up part of the cost. It's not cheap.
