Fixed the problem without any help from anyone. If you ask and ask and get no help I guess it is time to take on the problem and see if you can resolve it and I did. NO IT WAS NOT EASY but with a little thought and time over the last 2 days I did get the door changed. Thanks for letting me post even though I got NO help.

Sharp R-1874 works only by pressing the door in

Your connection is bad. Start with a good and complete cleaning of the product. UNPLUG FIRST. Sometimes in the hinges things gum it up. DO NOT STICK anything into the door latch area.
If this continues, you have an issue that must be decided if you should REPLACE or repair. Repair will cost more than replacing. Sorry.

This mircowave shuts off after 59 seconds all of the time ????

Change the Damper Motor and switch. Cost is approx $30.00 and you must remove the microwave from the mounting bracket and remove the cover to gain access to the motor and switch.

Sharp 1874- Door seems to "jar open" and oven stops

if you have a warranty get a new one installed they have to honor your warranty or better yet if they want payment you want new unit sometimes they come deffective from the factory ad you may have gotten one of them

Shuts off after 59 seconds

That would be a problem in the damper aseembly, either a bad switch or motor, or the damper door is jammed or blocked.

Consult the attached diagram for general reference.

The damper switch is the same as the primary interlock (door) switch.

If you or a friend decide to look into it, we have critical safety information, switches diagnosis and replacement, and disassembly information at our site, linked here on Fixya:
