Question about GE JE1640 Microwave Oven

Microwave Comes on when Door is Opened

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?

    I've not tried your fix yet. I may try it, but this is why I'm skeptical as to why it would work and possibly why your response got a poor rating. None the less, I do appreciate your response.

    In one way I can see where the switches may be the problem, but logically, I have a hard time understanding how.

    The reason is that if the switches were stuck and kept the circuit closed instead of breaking it when the door is opened, then it makes sense. But with my microwave, the door can be shut and the microwave off (timer timed out); then, when the door is opened the microwave immediately comes on. How could the switches being stuck cause this?

    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.

    I've tried the powering on and off solution, it didn't work. I've looked at the upper and lower door switch and I think it IS the upper one.



    Now I have to convince my husband to help me get the microwave down so I can pull it apart CAREFULLY. I'm going to try to replace the switch as indicated.



    And, many times we are guilty of interupting the cooking cycle by just opening the door. We'll certainly stop that now.

    I am having the exact same problem with this exact same model! ugh~

  • passportt Apr 14, 2009

    I have a 1996 spacekeeper II & the other day - I turned it off ( no dials on this one- just press pads - anyway - when I opened it - the light & fan came on - then when I close it - it all goes off- I wll look at the top slot - & try the wd40 trick - the other day I poked around pushing the bottom one - ( unplugged of course) I hope that is all that is wrong with it - as I have no $ to buy another one & I have been using it to boil rice & chicken quickly as well as heat some heating pad things I use for my back when I go to sleep- last night I was afraid to use it - thinking it might catch on fire or something ? ( can it catch on fire easily with this malfunction? ) well - any info appreciated - I grabbed a tiny 1985 model from my moms motor home & I am afraid to use it because it is so old!

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.

    It's almost always the top switch, but I hardly bother to get that specific anymore because some people don't seem to take my responses seriously. I think they're possibly killing the messenger...

    Anyway, it's possible yours got some grease in it and the WD-40 is indeed a fix.

    But it may be that you just loosened it up and it will eventually fail for good. Be ready for that.

    My advise to anyone with door switch trouble is to replace both the upper or lower or even all three and then develop a habit of not opening the door while it's cooking.

    Thanks for the follow-up! You are quite welcome.

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.

    It is not the fan that is coming on, it is the motor.

SOURCE: GE microwave (Model JE2160SF03) trips breaker when door opened

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.

SOURCE: GE Microwave JE1640 works only when holding the switch

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.

Why does my mwave oven often start itself when you shut the door even if you have not pushed start or have any time set on the timer. When this happens it does not tick seconds off on the timer.


I had one that started randomly when there was a power failure.
Never found out why. But when it did only the convection part came on. The mwave did not. U might experiment with some water in there to see if it heats up when this happens. If the mwave does come on then u should get it fixed or junk it. With the cost analysis, junk it is probably good.

It could be a loose connection that shakes when the door is closed. It could be a defect in the electronics.

Oven turns itself on


THE DOOR HAS A SAFETY SWITCH THAT SHUTS THE UNIT OFF WHEN THE DOOR IS OPENED KEEPING YOU FROM GETTING "ZAPPED WITH RADIATION" ACTUALLY ITS JUST RADIO WAVES, ANYWAY THE JIGGLING OF THE HANDLE TO START IT IS WHATS HAPPENING THERE. IT COMING ON IS JUST A SHORT IN THE SWITCH THAT MAY BE FROM AN ALREADY SET TIME, OR ITS JUST MAKING CONTACT WHERE ITS NOT SUPPOSED TO. ANYWAY YOU NEED A NEW DOOR SWITCH.

We have a Frigidaire FMV156DCC that is about 3+ years old. as of last night when the door is closed and the time is selected one of 3 things happen (or doesnt happen) 1. is nothing, just a dark...


I would replace the door switches and set up the door gap to 1/8" just enough to alow for a little play.
Setting the door square is acheived by slackening the lower door hinge and re tightening it when the door is square.
Hope that helps.
