Front right 2 ring burner knob DG9400906B Surface Burner Knob 2.5" Diameter NE58F9710WSAA Electric Range Replacement Part Used OEM # DG9400906B Surface Burner Knob This knob operated the front right 2 ring burner This is not a light weight knob. This part was pulled from my Samsung NE58F9710WS Range. I'll be listing more parts from this range. Please check them out. I also have the knobs for the small ring burner. They are listed in my "Samsung Range Parts" Category. They are in fair condition with minor wear. There may be some light scratching or marks or discoloration, nothing too bad though. There are some rub marks at the round bottom about 3/8" up but they will be covered once the knob is put on the range.
