I disabled the 3rd redundant safety microswitch of my microwave oven when it failed. There are now only 2 redundant safety switches left between me and the microwave not shutting off by itself if I yank open the door while it's running.

This is my right as an American! I don't have a pacemaker, nor does anyone in my family, and frankly, recieving a small % of 1000W of microwave radiation is not the least bit harmful to humans. (Lemme tell you a funny story about me and a microwave-oven magnetron in an RF lab about 15 years ago...)
