When I go to turn on the unit it seems to trip in the control box. The last 6" of the cord(which doesn't have the heavy plastic cover over the wire) where it plugs into the control box seems to be very twisted. I'm thinking there is a short in the wire. I'm reading .1 ohms on the wire and think I should be reading at least 3 ohms or higher at least. Can I replace the cord? Or any other suggestions
Thanks
Bob
