The ceramic insulator on the burner ignitor cracked & the spark shorted so that the burner would not ignite.

Firts I removed the 2 screws that held the burber in place. Then I lifted the burner up & disconnected the wire that connected to the ignitor. Then I removed the one screw that held the ignitor to the burner. I then reversed these steps, replacing the cracked ignitor with the new one, replaced the screw holding it to the burner, then reconnected wire, returned the burner to the stove and replaced the two screws that held it. All Done!
