No heat - element had burst.

Unscrewed 2 screws holding terminal ends of the element in place. Eased the element out, until the two AC power wires were exposed. Pulled off the connectors from the element terminals (pretty tight fit - needed pliers to remove one of them).

Slipped the connectors onto the new element terminals, and eased the element back into the oven wall. Secured the element with the two screws removed previously, and that was pretty much all there was to it. Closed the circuit breakers, and the element tested OK.

Overall, a no-sweat job. One thing, though: I squeezed the oven connectors tight before pushing them back onto the new element. They had loosened up somewhat after pulling them off. A tight connection here seems pretty important, as arcing and corrosion could occur over time if they're too loose.
