Question about Sharp R-1200 Microwave Oven
I have a Sharp R-1440 microwave and when the door is closed, it automatically starts. I have tried turning it off with all of the buttons, but no time is even displayed on the display when the microwave is on. The only thing that I can think of is that the door latch is somehow broken?
The buttons recently stopped working sporadically and now everytime I open the door, the unit turns on. The only solution was unplugging.. Is there a fix short of replacing it?

You probably have a failing door switch or the mount which holds your door switch is loose or broken. In most designs, it is the upper door switch that will produce these very symptoms when it is intermittent or its mount is broken or loose. Opening the door while cooking (without first hitting the STOP pad) is the primary cause of door switch failure. Slamming the door, damage during shipping or transportation and sloppy manufacturing techniques or materials are the primary causes of trouble with the door switch mounts. I have a text file called "doorsw.txt" which helps in diagnosing and repairing door switch problems, and a file called "safety.txt" which is of vital importance. If you or a friend decide to work on it, we have *critical* safety and disassembly info at our site, which is linked at our listing here on FixYa: http://tinyurl.com/yzjozk

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