Steve,Before I owned a Bradley Smoker, I was using a converted refrigerator with 2-electric hot plates,one for heat & one for chips.I had the same problem you are having, I could never get the temp above 200F,the knob had melted off from being on high for long periods of time & I had to keep opening the door to load chips.I couldn't find a suitable burner for the ol Fridgerator.The solution to all my smoking problems came the day my Bradley showed up.Good Luck
