Oven not holding 350 F, when cooling the coils did not reheat

Removed the oven door by opening slightly, then pic door up to remove. Remove 2 screws holding oven sensor in place, gently pull on sensor to remove, had to remove about 8 inches to get at plastic connector. Unplug connector, had to use an adapter cable supplied with the PartSelect kit to install new sensor, push cable back into opening, reinstall 2 screws. The oven works fine! Note that due to thermal lag the temperature overshoots to 370 degrees and undershoots to 340 degrees, this appears to be normal oven operation. Putting door back in place was easy.
