Question about GE JE1390GV/WV Microwave Oven
Posted on Nov 13, 2010
Microwaves have protection circuitry built in so that if they develop a "Fault' then they are shut down. So a MW that doesn't work is a common symptom.
Most usually the fault is to do with the magnetron, and or the High Voltage diode, and or the Power Supply. There is not all that much to a MW. However sometimes it can be a "Door" switch,or some "Protection" mechanism that's been invoked for whatever reason.
One must perform diagnostic steps to isolate the problem, and repair, which requires a service manual, tools and knowledge.
MW's are very dangerous device to service and in my opinion should always be serviced by a professional. They have a very large Capacitor, that stores enough Joules to kill anyone who touches it. It remains charged even when the power is removed and must be discharged each and every time after it has been powered on..
Always ask for a 'Quote' from the service agent before allowing any repair work to be undertaken.

there's no obvious removable cover over the bulb (and the owner's
manual doesn't address it) some disassembly may be required.
Always unplug a microwave before removing or installing any bulbs.
If it's an over the range type, remove the vent grille across the top and see if bulbs can be accessed there. There may be a panel on the bottom covering the light(s), instead.
If not, chances are you'll have to remove it from the wall, then remove 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.
If you don't have your instructions, please reply back with your brand and model number.
Once it's out of the wall, the outer cover (wrapper) will need to be removed, just as you'll need to do on a counter top model.
On a counter top model, be sure it's unplugged, but otherwise ignore the instructions above this paragraph.
The screws you need to remove should be pretty obvious, but a special driver (such as a T20H Torx type or GTXH20-100) may be needed.
Be sure to put all the screws back in the right holes, since some may be special grounding screws.
Bulbs can be had in most grocery stores, hardware stores, home improvement centers, and big box or department stores.
Many models use halogen lamps. You must not touch the new one with your bare skin, as the oils will shorten the bulb life.

Sounds like you have a faulty control panel. I would use a meter and test the power from the control board to the magnetron and circuit board. Chances are the control panel is faulty
