KitchenAid Microwave Door Won Open

If the top is open, the upper door switch should be open and the high voltage section should not be energized. That's the way it's *supposed* to work. But that buzzing is worrysome! Does the turntable turn during this condition? Does the inside light come on? How about the fan? If not, then I would doubt that it's cooking. If so, some models will do this. It's not uncommon to notice that the fan and light will try to come on for a split second when you shut the door. This would not indicate a problem. It has to do with the timing of the door switches and a replay on the board. If it's still under full warranty, it wouldn't hurt to call a GE-authorized servicer.

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!

I believe the only way of gaining access to the door latch assembly is by removing the cover. You can use needle nose pliers to grip the sides of the screws to slowly turn them out. You might want to visit this web site www.applianceaid.com enter your model number then scroll down until you see an exploded view of your model. Click to enlarge the diagram of your model exposing the latch assembly. I hope this is of help to you. If you found any of these suggestions helpful, please rate my solution. D. Lange

What usually breaks is
the door open lever, but it may also be that the rear side of the door
open button has worn down too far to work.
On
a counter top model, the outer cover will need to be removed to
diagnose and repair this. On an over-the-range model, usually only the control
panel needs to be removed.
Once
it is apart, you'll be able to see how the door open button would press
against the door open lever, which would then lift up against the door
latch heads (hook-like projections on the door) and the door should
open.

HI, this is an indication of a failed door switch. When the switch fails, the control cannot recognize the closed door signal. Simply replacing the door latch mechanism will solve this issue.
Replace the door latch assembly, asap.
