It was a simple repair that only required the removal/replacement of 4 screws. The first two sheet-metal type screws required a 1/4" nut driver and were easy to remove. The second pair of screws that fastened the electrical wires to the element itself required a pair of "Vice-Grip" pliers to remove; due to the fact that the last person who replaced the element used improper sheet metal style screws. NOTE: On the new element, the manufacturer furnishes the proper machine type screws for attaching the electrical wires; they are taped to the element itself. These were easy to replace and only required a Philips screwdriver.
