We saw a failure case like this with a microwave in the workplace kitchen. It somehow got into a mode where it only turned on when the door opened. Needless to say we threw it out shortly after that was discovered. We didn't bother debugging it, but my guess is it was a hardware problem because the interlock should have obviously made it work the opposite of how it was and you'd hope that a software glitch couldn't get it into a mode like that!
- tomc1985 6y agoOh crap. That could blind a person. I thought microwaves had to have a hardware interlock for that reason
- dublin 6y agoSince this is critical health and safety stuff that can lead to serious injury, everyone I've ever seen uses hardware interlocks - generally, the door-closed switch is in series with the microwave power supply, so it's impossible for it to make microwaves with the door open. Only an idiot would put a safety interlock under software control, when a simple switch will do.
