Buzzing noise and burned smell

SOURCE: burning odor, no heat

A burning smell along with a different sound (growl) USUALLY indicates a breakdown in the High Voltage Side. This is not a direct short (short circuit) or the line fuse would have blown shutting everything down. The High Voltage Side is made up of-- The Secondary ,or High Voltage Side of The High Voltage Transformer, A High Voltage Diode, A High Voltage Capacitor, and The Magnetron. If The High Voltage Transformer is the problem it will smell like a florescent light ballast burning, and will smell each time you turn on the MW. A HV Diode burns and opens, thus no more smell. A HV Capacitor usually does not burn nor does the Magnetron. There is no Cheap-Fix unless you can see that the HV Diode is burned into and you can get to it to replace. CAUTION: Always unplug from power before attempting to repair. NOTE: If you replace a Diode make sure it goes back in the same direction it came out. Yes there is a front and back.

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

After the way GE behaved by doing business with Iran, wouldn't buy a thing from them. look for the equivalent product from another source. Jeffrey Immelt's citizenship should be revoked and he should be sent off to live on a deserted island

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.

SOURCE: I have a JVM1630WB GE Spacemaker microvwave oven.

It's almost certainly a shorted high voltage rectifier diode or a failed magnetron.

We have the service / repair manual for this model and have uploaded it to our site here for free download to help you.

It will give you safety info, step by step help in disassembly, troubleshooting tips, and part numbers.

Here are some handy links you or someone you know can use for test help:

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

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.

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.



You can also find helpful exploded view diagrams and order parts by entering your full model number from the tag on the oven here.

If it's within the magnetron portion of the warranty (for this model it's 10 years from the date on the tag inside the unit) but out of the original full warranty (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.

G.E. they will send you the magnetron to do it yourself. Call them at 888-239-6832.

Be persistent. You may have to speak with a supervisor.

If it is not within the magnetron warranty, you can find helpful exploded view diagrams and order parts by entering your full model number here.

Accessing some components (especially the oven cavity thermostat) for testing and possible replacement will require you to remove the oven from the wall and take off the outer cover.

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.

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

from what you are discribing , I would be looking at the high voltage transformer
