Replaced the element. Although the repair was a variant on what was shown in the video, e.g., I needed a nut driver rather than a screw driver and the electrical connections were screwed together rather than simple spade connectors, the time it took me from cutting the power to the oven from the breaker box to restoring power was 14 minutes. That included a bit of cleaning as long as I was in the oven. The replacement part was a perfect match. I immediately mixed up a batch of cookies to test the oven with delicious results.
