Switches needed to be replaced. Make note of where each screw comes from. They were not all the same. To remove the front panel and get to the switches, you have to partially remove the cook top. Removed 5 screws from the back to release the cooktop. Slid the cooktop back far enough to expose screws holding on the front panel. Removed 4 screws from the top and 6-8 from the bottom (opened the oven door to get to the bottom screws). Removed screws from the front panel holding the switch in place. Took a picture of the wire orientation on the existing switch. Removed the wires from the old switch, attached to the new switch and put everything back together. Some of the wires were a little difficult to remove from the old switch. Some seem to snap off easily, others took a little effort. Repair was not very difficult if you keep track of where everything came from. To me about 30 minutes of actual work. Another 30 minutes or so cleaning the years of grease buildup before putting it back together.
