Congrats, Ed! You know the Auber is working if you see the little green light on the right side of the display lit. It will pulse from bright to dim, or off, depending on how much current it is sending to the element. When the Auber is on, you'll also know it's working if the smoker heats up.
Just make sure your dial is set to 250, or the on board controller and Auber will have a death match for control of the smoker!
