Replaced heating element. Took less than 15 minutes to actually replace the heating element. The repair video was extremely helpful. Gathering tools for the repair along with testing and cleaning up afterward took up most of the 1-hour project time.
For tools, used a #2 Philips screwdriver, some scrap wire to anchor the heating element wires during disassembly, needle nose pliers, and an awl to line up the screw holes during re-assembly. Pretty straightforward repair. Made the repair without removing the built-in oven from the wall or removing any panels or doors.
