David W Acworth , GA October 11, 2015 Appliance: KitchenAid 30" Free Standing Electric Oven Convection KERA807PSS00 Kitchenaid Range Kera807pss00: Two of the four switches that control the heating elements did not work properly. How to replace Infinite Switch Kit. The switch replacement requires changing out the wiring harness as well as the switches. The procedure starts with the cooktop off the range. It would have been nice to have the details for this in the instructions. The new wiring harness is slightly different in that the hot surface indicator wiring is no longer needed. It would also be nice to note this in the instructions. Other than these two minor issues, the replacement switches work better than the originals and the knobs on the control panel actually are captured much better. Took about 2 hours with help from my son. It was an easy project for us to do together. Do-It-Yourself Rating: Repair Time Estimate: 2+ hours
