Cut power to the range/oven. Pulled the oven unit out from the cabinets/counter enough to reach around back. Pulled the burner knob off. Removed 2 to 4 1/4" bolts (I don't remember how many) holding the steel panel that covers the controls section of the unit in the rear. Removed two phillips head screws that hold the surface burner switch in place. Visually checked the new part to make sure it was the right one. Removed each wire from the old switch and reinstalled them on the new switch one at a time. Reinstalled the new switch and knob, turned power on and tested it to see if it appeared to cycle the burner on and off at an interval that matched the knob setting. Slow cycling on low setting and fast cycling on high. Put it all back together. Works great.
