Turned stove breaker off in the main breaker box and also unplugged the oven from the 220 outlet. pulled the baking racks out of the oven and proceeded to locate the 1/4 screws just above the bake element where it passes through the metal wall and removed them. pulled the element forward until the wires were exposed and unplugged them and then attached the new element to the wires and reinstalled in reverse order.
