Dennis L North Easton , MA November 14, 2015 Appliance: KitchenAid 30" Slide-In Electric Oven KESS908SPS00 Kitchenaid Range Kess908sps00: Cracked cooktop from clumsy drop of container. How to replace Cooktop. I followed the detailed instructions posted by Robert H in May 2014. I had a little trouble lining up the plastic guide pins with the holes in the control assembly, but other than that it was very easy. The only reason the replacement took more than 6 or 7 minutes is that I opted to clean the gunk off of the rubber gasket. Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
