Kevin R Plympton , MA November 18, 2016 Appliance: Maytag 30" Gas Built-In Downdraft Cooktop JGD8130ADB20 Maytag Cooktop Jgd8130adb20: One burner the burner was rotted other burner the igniter was not working. How to replace Top Burner Spark Igniter. Lifted out the burner assembly on right side of cooktop which included the two burners that needed repair. Opened up the assembly by removing four screws and that gave me access to underneath the burners. Removed the tube and the igniter from bad burner. Put new burner in place and attached tube and igniter. Took igniter off other burner and put new one on. Put assembly together and put back into place. 2 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
