Question about Sharp R-1850A Convection/Microwave Oven

Sharp Microwave model R-1850A door won't open

My microwave has been working great... until suddenly I couldn't get the door open.

I finally managed to open the door by pushing the "open button" and pulling on the edge of the door.

The latch bar on the door seems to be working fine. The spring is still there and the latch goes up and down and has plenty of tension.

The door will shut and the oven still operates... however it is very hard and almost impossible to open. It normally just pops open when the tab button is pushed.

While the door was open I looked at the inside where the latches fit... when you push the button tab you can see something moving. I'm assumming this is the piece that releases the latch and opens the door. These slots on the top and bottom where the latches fit do not look the same. Could there be a piece that has broken off?

Thanks for your help!

    My Sharp Carousel microwave (not sure what model #) door will not open at all. I cannot even pry it open. Everything else works fine. Any suggestions?

    The microwave is working fine but....the door won't open when you push "open door". I have to open it by pushing the open door button and pulling on the edge of the door on top. All the buttons and latches seem to be fine but it doesn't pop open anymore. How do I fix this?

    Thanks for your help,

    I have Model 520KS and have the same problem.

    You need two hands to open the door. The release button is cheaply made of plastic and won't release the door. The first Sharp microwave I had lasted 21 years. This one is only 2 or 3 years old and already needs repair.

    Appears like some type of short between the door open button and door latch that makes the microwave display blank out.

    I hear the click that should release the door and the interior light comes on, but the door doesn't open

    Push button that controls door locks up. Door can't be opened. Took unit apart. Can't see any problem. At first, button was "touchy" - now it can't be pushed in at all.
