But if the diode at a lower temperature than the resistor can generate current, then the current should raise the temperature of the resistor, meaning that it will stay running.
That seems unlikely, as I understand thermodynamics. Can anyone explain?
Current in a resistor will raise the resistor's temperature.
Current in a diode also raises the diode's temperature.
It takes work to keep the diode at a lower temp.
The diode won't be at a lower temperature for very long.
