    When you hit Start to
    cook, do the inside light, cooling fan and turntable come on?




    Any unusual noises? Is
    it louder or quieter than usual?




    These answers will help
    me judge whether it's in the high voltage
    section (magnetron, transformer, or diode) or the control section
    (door switch or control board relay or connection).

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 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:

http://www.gallawa.com/microtech/diode.html (if it's not shorted, it's probably okay)
http://www.gallawa.com/microtech/mag_test.html
http://www.gallawa.com/microtech/xformer.html

You can usually find helpful exploded view diagrams and order parts by entering your full model number here.

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

    The metal band would not have caused any trouble unless it arced or the pot was empty.

    I would be interested in buying your oven's control panel assembly before you scrap the oven!

    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.

    Once the control panel assembly is removed, there is no toxic material in what's left, and it can be left at the curb for scrapping, recycling or freecycling.

    Feel free to contact me directly (and please remind me of your
    full model number) if you're interested.


    I can pay with PayPal or money order, as you prefer.

    Thanks!

Hi
Please check if any fuse is blown inside the microwave. If the fuses are fine then the issue is with the door switch of the microwave, it may be faulty or may have loose connections. If the switch is faulty then you can get it replaced. Hope this helps...please post back for further assistance.

JVM 1440 GE microwave stopped heating. all other functions work great. where do I start


GE microwaves are notorious for the magnetron failing, this is what generates the microwaves. Usually the unit will make a louder than normal deep hum when running if this is the case, but not always. If you have the schematic, you can measure for 120 volts leaving the control board to the transformer, you can simply measure the line in on the transformer for this. You also want to visually note that all other functions like the countdown timer, inter light, turntable, and fan are all running when you start a cooking cycle. The monitor, and interlock switches mounted on the latch assy need to be checked for continuity too. If replacing the magnetron we always recommend replacing the high volt diode connected to the capacitor and chassis ground. Pleazer Appliance...

I have a GE spacemaker microwave oven model JVM 1440. A bulb blew and when I went to change both over the stove bulbs stay on all the time. What is the problem and what should I do.


there is some kind of circuit board damage. carefully check for burned foil paths on board; around where the relays are. if so, you may be able to "bridge" the broken foil paths with solder. just unscrew the bulbs in the meantime.
