Now that's some extremely bad timing! We have an ancient window air conditioner that did some sort of really weird thing where it went through all it's numbers. It went from 00 up to 99, then ran through turning everything on, it changed Fahrenheit/Celsius several times, even set it's own Economy button. I wasn't sure if it needed a repairman or an exorcist to be honest. Then it just started working again. I don't know if it was a self-test, or what it was. But since it's working now I just left it alone(but I only have it on when I'm home and don't set a timer or anything, because that was weird.)
Misery...
