When I worked on Windows Phone 7 for Microsoft there sometimes a risk you could load a new version of the O/S you had just built on the phone and it would fail so catastrophically that it couldn’t even boot up enough to load a new O/S to replace the broken one. We called this “bricking your phone”. You had turned your smart phone into an object that was about as useful as a brick.
A few days ago Barb L. decided she needed to use the self-cleaning feature on her oven. The oven is fairly new and she had always cleaned it by hand and sometimes with oven cleaner spray. But this time she “dinked around” with the controls and got it to do a self-clean. After about two hours she decided it was probably done and turned it off. She went back to the oven a while later and the door was still locked. The display was off and all the controls were dead. She went to breaker box and cycled the power. It was still dead. She left the power off over night and turned it back on. It was still dead with the door locked.
Barb is the only person I have ever heard of that is able to brick an oven. That takes some special talent. She’s a keeper.
