Answer Will, It's a bit involved, Remove power and the gas sup[ply to the cooktop. Remove the burner knobs and grates. Label and remove all the burner caps(turn 90 dgrs. counterclockwise) label the wires. Remove the two small phillips head screws located under each of the burner caps, and once removed, lift the drip pan out of the opening in the cooktop. If the cooktop is installed properly, you should b able to use a stiff flat bladed tool to separate the cooktop glass from the burner box and lift it up and off. You may want to order 74002138 along with the spark module, it could get damaged during the repair. Thanks and Good Luck Read More... Answered by AppliancePartsPros.com | Tuesday, July 3, 2012
