This GE JVM1440BD microwave has the only problem it doesnt warm. All other features work properly, even when you start it the light and the fan come on, and the glass plate starts rotating, but it doesnt get hot at all. I suspect the problem is the magnetron because the microswitches, fuse, and termistors are ok. i would like to know what test could i take to be completly sure and where can i get a replacement for the magnetron in LA area.

Re: no heating jvm1440bd
Before you take it apart, yours may be a model covered by a campaign under which GE is replacing "underperfroming" magnetrons and also putting in new stirrers and high voltage diodes.
See this bulletin to see if yours is one of them:
http://207.234.249.73/mwd/ge_mw_mag_kit_bulletin.pdf
If it's not covered, then we have *critical* safety & disassembly info at our site, which is linked at our listing here on FixYa: http://tinyurl.com/yzjozk
While you can't be completely sure without experience, there is a technical sheet in an envelope inside the oven which shows how to test the magnetron with an ohmmeter.
Essentially there should be near zero between the two terminals, and infinity from either terminal to the case.

We see (and repair) this
a lot. The problem is on the control panel, which
we regularly repair nationwide by mail for $39.95 postpaid in about a
week.
At
our Web site, you can get details of our service, plus we have a video
available showing how to remove a typical
over the range control panel assembly in under 5 minutes.
This light failure often
occurs when a bulb goes out and the filament
shorts, or when the bulbs are removed or installed without first
unplugging the oven from the power line. Either can cause such a
failure on the controller.
This can often also
affect the exhaust fan operation, too. The lights and fan can be
inoperable or stuck on too.
If your relay is bad and you want to replace it yourself, it is part # 3501-001050 and you can find
helpful exploded view diagrams of your microwave and order that part here.
Be sure to also do any needed circuit board repair with 30AWG wire to prevent it from doing worse damage if another bulb shorts.
Feel free to contact me directly (and please remind me of your
full model number) for more information & help.

The turntable system
consists of the motor, the coupler, the turntable support with rollers,
and the tray.
You can see and hear a video of how a turntable motor should
sound when you rotate it by hand.
If
yours is not set to be off via the control panel, and it won't rotate
or it sounds like it's grinding, etc., you may have a bad motor or
plastic coupler.
To
replace either, you need to unplug power, then remove the bottom cover
of the oven.

There
should also 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.

our Web site, we have a video

I thought I had answered this, but maybe the reply didn't post...
Vent cap?
Could you be more specific about what you tried and what the noise is like - where it seems to be coming from?
It looks like on some of these models, the high-voltage section emits some interference which some people are blocking with a foil or metal shield. If they do that, they should definitely insulate it to prevent shorts.
Another cause of vibration on these models is a fault in the stirrer located above the cover on the ceiling inside the cooking cavity.
Feel free to post back so we can help further.
