After looking at exploded view of controls (on your website) it appeared that I needed a new spark module and/or a new wiring harness. I ordered both parts (which were delivered in 2 days). After remoiving the burner elements from the cooktop and unplugged spark ignitor wires from burners the top was removed easily. The new parts were installed using diagrams supplied (and common sense by color coded wires and numbers on spark module). The wiring harness was also easy to install by noting how the original harness connected (video helped in seeing how individual burner elements of the harness were removed and new installed. Total time for repair approximately 45 min. Power and gas were off during the repair.
