Online chat here said that the oven sensor should be replaced. I got the feeling that was a bit off, so I went with my gut and ordered the thermostat as well. Replaced the sensor and that didn't fix it. Replaced the thermostat and it worked like a charm! Disappointed that they were overconfident in their answer and it would have taken me more days to fix - but, the products came in quickly (basically, next day) and were correct. Online video for my particular oven was incorrect - but it's an easy fix if you're comfortable pulling a wall oven out (onto sawhorses) and taking the back cover off.
