Removed the broken element by taking out the two screws in the back wall of the oven and unplugging the wires. Then did reverse to install the new element. Very simple repair job.
turned off the breaker (240 volts and it was outside, so it took longer than 15 minutes). Removed two screws in the back of the oven, one on each side of the old element, and pulled the old element forward. The wires on the back add some resistance, but they are long enough to pull forward a short distance (3 inches) without damage. Unplugged the old element, plugged in the new element, pushed it into place, and reinstalled the screws. Turned the power back on and it worked! Saved some money for the holidays! DIY para vida!
Turned the circuit breaker off. Removed the 2 screws holding the element in place, pulled the element out far enough to access and disconnect the wires. Installed the new element by reversing the process. Success - wife is happily baking again!
