SOURCE: Stuck Microwave door

The button assembly or the arm thats attached to the push button is broken. With the unit unplugged. Carfully take off the screws from the sides and around the back of the unit around the outside of the cover. Now once apart, DO NOT TOUCH any electrical parts. Look at the mechanism and see if you can see why the buttons not activating an arm to trigger the door latch. If you think you see why, Go to http://www.repairclinic.com and enter your model #.. Answer the questions and then a bunch of parts will come up. If they dont then get the tele # from there and call them. Depending on how old the oven is, you may want to consider a newer oven??. Good luck

The push button that opens the door on our Sharp Carousel R-1406F over the range microwave, is broken. We can push it in but it gets stuck. I cleaned it out because it was kind of dirty but it didn't...


It may be the door open button or the door button lever. Sometimes grease is the culprit, other times the surfaces where these two meet get worn, making the door harder to open.

Sharp microwave door will not shut and the oven light stays on continuously.


The door has a switch , probably two, that engage and disengage when opening or closing. ( a failsafe so it switches off ) when you open the door, this is the problem also like a fridge the light should go off when door is shut, it may just be stuck but Dont mess with it , clean it if its got food stuff , a mild detergent round door etc , otherwise just change microwave ,

Door Won't Close


What usually breaks is the door open lever, but sometimes there's just a grease buildup around the door open button.

On a counter top model, the outer cover will need to be removed to diagnose and repair this. On an over-the-range model, only the control panel needs to be removed.

Please unplug the oven first.

If you or someone you know wants to look into this, we have critical safety, disassembly, and troubleshooting info at our site, and our link is at our listing here on FixYa.

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.

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

If it's a Sharp or Kenmore, you can usually find exploded views and order parts by entering your model number here at the Sears parts site.

The best place to order Sharp parts is Tritronics.

If you still have trouble, please reply back with your model number so we can help you.

Sharp Microwave oven controls do not work


You mean the turntable motor turns whenever the door is shut, even if you're not cooking?

If that's the case, then the problem would probably be a stuck relay (RY3) on the control circuit board, which we regularly repair nationwide for $39.95 postpaid.

If you have a different problem than I described, please reply back with details before you give us your rating.
