lower heat element would not get to temperature

Slide stove out and unplug. Using nut driver (phillips screw driver would work fine) remove screws securing back panel. Remove back panel. Pull off wires from heating element. I made a lose knot on left wire so I could install as removed without confusion - sometimes it matters. Removed 2 screws securing element inside the oven. I installed everything as it was - oven works great. I saved over $100 and my wife thinks I'm a genius. Hardest part was cleaning accumulated mess behind the stove.
