Question about Sharp Microwave Ovens
Sharp Carousel Mod: R-4A56. Door will not open nor close with use of door "button". Worth repairing? Can I repair? Parts necessary. Dangerous to use in this state? Thanks for the assist.
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.
Please unplug the oven before disassembly.

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 exploded views and get part numbers by entering your model number at the Sears parts site.
The best place to order parts for this brand is Encompass (formerly Tritronics). Or you can call them toll-free at 866-779-5835.

Sounds like an intermittent door switch or a loose door switch mount. Very common.
