VERY simple fix- you do not even have to pull the range out.. I ordered a new cooktop from Appliance parts Pros. The customer sales rep Alphonso was great and walked me through the general process. I could find no explicit instructions for the repair but I muddled my way through. The fix is simple on Kitchenaid/Whirpool slide in ranges. 1. Open the oven door and remove the two phillips head screws directly below the control panel that hold the panel down.2. Lift the control panel upward and out. You will need to finesse the gasket between the control panel and the cooktop a bit as the gasket can stick from grease etc. You will also need to prop up the control panel while you work. I partially closed the oven door to form a small quasi- shelf and my wife balanced the control panel on the "shelf" while I worked. 3. Remove two phillips head screws directly below the top that retain the front of the cooktop. There is a metal gasket retainer plate that also come off as the screws are removed.4. Gingerly lift the old cooktop up and out towards the front. The rear of the cooktop is retained by two small prongs that are integral to the cooktop. The process may require a little finesse as the gaskets under the top may stick a bit. 5 Clean all the gaskets with degreaser ( I used a rag and a little mineral spirits. 6. To assemble just reverse the whole process. Make sure that the cooktop is retained by the prongs at the back and all the way back before fully laying it down as reassembling the front screws.
