Sounds like the problem is in the high voltage. Most common would be magnatron, capacitor and diode. For safety reasons this should be checked by a professional. Look in your owners manual because some high voltage parts have a longer warranty than 1 yr.

Thanks for making your post very detailed and including the model number. That really helps! :)

With the symptoms you have, I would most strongly suspect a shorted high voltage rectifier diode or a bad magnetron.


The diode is a fairly easy & cheap do-it-yourself fix, and the mag will cost more.

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

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:

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: 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.

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:

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.

Microwave not heating food


It's most likely the Magnetron. The are not very easy to install and quite expensive. Older models magnetrons cost about 80 bucks from GE. It's probably not something you would want to try and repair yourself. Call a GE service person.

GE Spacemaker microwave won't heat food


hello kmwnky,
You say that Everything went out at first ( which I assume means that all functions went dead) and then functions started to operate again later... if that is correct and you smelled something burning.. you may have a thermal fuse that failed, filament transformer that failed, magnetron tube that failed or a highvoltage capacitor that failed.. None of these components are something the untrained person should attempt to trouble shoot or replace since there are dangerous energies stored inside the electronics compartment even after power is removed.. Your Micro is > 8 years old and it's probably not worth the cost of repairing at this point. You'd be better served replacing it.. The cost to repair would exceed the cost to replace.. ( I feel like the grim reaper here..sorry..)
Regards,
Rick

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.

GE JVM130 001 Over Range Microwave does not heat


It's probably the high voltage rectifier diode or magnetron.

The magnetron will have a guarantee lasting about 5-9 years, so if it might be covered, contact GE at http://www.geappliances.com/service_and_support/contact/

If you or a friend decide to work on it, we have *critical* safety, disassembly, and troubleshooting info at our site, and our link is at our listing here on FixYa: http://tinyurl.com/yzjozk

Also, there should be a very helpful "mini-manual" hidden inside the unit behind the control panel.
