Jeff P Poway , CA February 02, 2016 Cracked glass cooktop Switching out the glass cooktop was very easy. I was extra careful when transferring the burners from the old cooktop to the new one, so as not to damage them. That part of the project took me 1/2 hour tops. The part that took awhile was cleaning everything while I had it apart...lots of sticky gunk built up on top of the burner control unit that took a bit to clean. Also had some issues with the vent ducts, but that was specific to my project and would not necessarily be an issue for most. 2 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
