(fascinating that there are no electronics in these things, it's all just mechanical, temperature activated contacts and a mechanical timer, plus a motor... big control system with no microprocessors. If all the conditions are met -- below low temp, below max temp, no blown fuse -- then the circuit is complete, and there is power to the gas/igniter circuit. If conditions not met -- max temp sensor too hot, low temp sensor above threhold -- it doesn't fire off the igniter). No CPU cycles involved. #random #dryer #pondering
