Do-It-Yourself Stories from Customers like You No spark or red led gas cooktop working with a lighter.   Devang R. • San Ramon , CA • June 23, 2022

The ordeal began after wiping around burner knobs with a moist paper towel with cleaner and wrapping the towel around the burner knob shaft to clean around it. The cooktop stopped sparking on all the 5 burners and no red LED light. There was gas flow and I could light the burner using a lighter. I looked up and found a couple of good youtube videos on troubleshooting and also came upon the AppliancePartsPros.com site. I opened the cooktop (youtube video helped) after turning off the gas supply... Read more
