Sandra C Waldorf , MD November 15, 2015 I want to replace the cooktop I want to thank Dan for being so helpful. He took the order on Nov. 11th and I got it Nov. 12th. My handy man fix it while I was at work. I do not know what tools he use to replace the parts, but they fit perfectly. I like the all purpose appliance cleaner too.
