Default Re: Heater quit... sort of

FYI -- The tempy control knob is really a voltage divider circuit. Rotating the knob lowers or raises the voltage (level) going to the control unit. I could see that if one wire or another was broken -- it would either cause the control signal to be seen as hi temp or lo temp setting by the controller.
