The two xl burners on the left do not light up but the ignitors work. When the front right burner is on, all ignitors continue to spark until I touch (ground) the pot that is on the right front burner while it is working....then, all ignitors stop. When both of the right burners have been ignited, the ignitors spark faster and continue even when I touch the pot on the burner.

Any ideas?
Happy New Year to all!!
