Purchased replacement spark module. The module is located under the cooktop so had to replace by squeezing under the cabinet to get access. There is a metal plate that covers the module that needed to be removed-four screws. Unplugged the AC to the cooktop and unscrewed the module from the cooktop. Then, one connection at a time, I removed each wired push on connected to new module. After connecting all wires I reattached the module to the cooktop. Amazingly it now works just fine.
