Suburban 3 burner range lighting problem solved

[tinkerreknit]

I was going to ask for help on this great forum, but I solved it myself with little trouble. I have 3 burners, and the center one stopped lighting with the click/piezo thing. The other 2 burners ignited with a click, so I suspected a food spill or something similar. I cleaned the burner mounting screw area (I don't think that matters though), and I used a can of compressed air blaster to blow out the burner itself. But I think what worked was when I lightly steel-wooled the electrode and the burner housing in the area as shown in the picture. Maybe this will help others with this problem.
