Time for repair: approx. 20 min; removed oven door to make access easier; removed 2 retaining screws holding sensor to back of oven; removed 3 retaining screws from back panel (on rear of stove) to assist in rotating wire connector thru access hole in the back of oven; the wires were JUST long enough to pull connector thru hole; had to keep them in place by attaching a small hemostat to hold (clamp) connector while unplugging old and plugging in new one - otherwise you need a second person unless wires are longer.
