Have a 3 yr old GE JVM1441BH over the range microwave. Microwave emits a loud continuous buzzing aproximately 1-2 seconds after starting. Lights, turntable, panel display all work properly. No heating occurs. Have tried unlpugging for the day and plugging back in.
I've read this may be due to a faulty magnitron. Any other possibilities? Will everything still work if the fuse is blown? I expect not.
I have everything disassembled and will start testing the mag, and transformer as soon as I can borrow a multimeter.
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 your magnetron is still under the part warranty, but you would have to pay labor.
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.
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)

Since it's within the magnetron portion of the warranty (5-9 years)
but out of the original full warranty (1 year), G.E. will cover the part cost, but not the cost to visit you or
the labor charge to do the work.
If it's within the mag warranty,
G.E. should send you the magnetron to do it yourself. Call them at
888-239-6832 with your model, serial, and manufacturing date.
If nothing else, you
can save about $50-75 if you remove it from the wall and take it to a
GE-authorized servicer.
You can find a
GE-authorized servicer by calling GE Appliance
Service at 1-800-848-7620 or here.
Accessing some components for testing and possible replacement will require you to remove the oven from the wall.
If
so, the installation instructions are very handy, and it's best to have
two people since the microwave can be heavy and awkward.
You can download GE
owner's manuals and installation instructions here.

My 4 year old of the same model just up and quit heating. I hate this brand. I was dissapointed my builder put these in,.. but couldn't complain about the price of the house... now I know why... they skimped on the appliances. I'm not paying $80 to have a GE repair guy come in and fix it... and then charge me more for the parts. I am not a repair-it-yourself kind of guy. I tried reseting it too, but began to smell the wires heating up... not a good sign. Guess I am going to have to buy a new one... but certainly not this brand... ever, ever again. Next time I have a house build, GE is not coming anywhere near my house.
