Question about GE JE1640 Microwave Oven
Here's a wierd one. Every time we open the door to the microwave, it comes "on". And this happens even when the timer has timed out. It's like there's a switch on the door that says "come on" when the door is opened. I don't see any mechanical switches on the door to reset. I've also opened the breaker to cut power off to the microwave in hopes that it would possibly reset a malfunctioning electronic control circuit; it didn't correct the problem. Any suggestions?
It sounds like a problem with the door switch or mount or the control panel. I've attached an exploded view of the oven which shows the door switches and mount. They're located behind where the door hooks go into the chassis. You can find our safety and disassembly instructions at our site via my link here: http://tinyurl.com/yzjozk If it's not switch-related, then you may have a shorted component on the control board. We repair these for customers nationwide for $32.50 postpaid in most cases.

Most microwave ovens run the fan when the door is open. I believe that this is what is happening and you are not getting any microwaves from your magnatron.

Well. The top switch on the door actually was the problem. It was sticking in the closed position. I exercised the actuator and sprayed some WD40 on it and it's working fine now. As a side note, after looking at the schematic and tracing current flowpaths, only the fan, turntable and light were coming on when the door was opened. In order for the magnetron to power up, all three switches on the door have to be have to be made. Thanks for your help MicrowaveSvc.

Remove the control panel, take pictures of the door switch wiring while they are still connected to the door switches, then remove the door switch assembly. Have someone at the appliance store check each switch and repair the ones that are defective.
I purchased a switch for $7, reinstalled the door switch assembly and the microwave is working fine now.

VK, most likely the switch body has become loose and it's out of adjustment. Unfortunately, to gain access to it, you'll have to remove the MW from the cabinet, set it on a suitable work area and disassemble it. Before doing anything like this, please read the following link carefully and ask yourself if you're up to it... http://www.gallawa.com/microtech/safety.html Remove the trim then remove the screws holding the MW. Pull the MW out and rotate slightly to see where it's plugged in and unplug it. Then pull it all the way out. Remove all the aluminum trim from the MW and all the screws holding the cabinet. To remove the cabinet, stand behind the MW and grasp both sides... pull back and up at the same time. Set aside. NOW!!! DISCHARGE THE CAPACITOR AS PER THE INSTRUCTIONS IN THE LINK ABOVE!!! OK, up by the control panel, you'll see the latch/lock assy. (it has 3 brown switches mounted to it). It's held in place by 2 screws, the lower screw is the one you'll be working on. Adjust this by opening and closing the door and watch the action on how it works and make your adjustments as needed. Now, you'll need to test it before reinstalling. Plug it in, BUT DON'T TOUCH ANY WIRING! Now give it a try. If you need to make another adjustment, DISCHARGE THE CAPACITOR AGAIN BEFORE DOING SO!!! Do this every time you plug and unplug! Continue adjusting 'til you get it. Now, there's a chance that one of those switches is about to go bad and the mounting bracket is fine. In this case, those switches are generic... not GE specific. Remove the wiring from the switches and make notes on their respective locations. Remove the switches from the bracket (starting from the top) and label them 1, 2 and 3. Take these to your local appliance parts store and ask for generic replacements, they are cheap... about 5 bucks each. Then replace them in the same order you removed them. And re-test. This will get you fixed, but please be careful working on Microwave ovens. They are dangerous!

SOURCE: Tripping of circuit breaker
Check what other appliances are on your circuit. What goes off when the breaker is tripped. You may need to relocate the microwave to a different circuit. Try to stay away from the refrigerator or AC circuits.
