Unplugged the oven, removed the back cover, unhooked the lower element from its connectors, and tested the resistance with an ohmmeter. It had no continuity at all, so i ordered the replacement. When that came, i unscrewed two screws from inside the back of the oven, pulled the old element, put the new one in and put the screws back. Then on the back side, i connected the spade plug on each end of the element to the appropriate wire, put the back cover back on, and plugged in the oven.
