Hello,That is typically a dirty flame sensor rod. You need to remove the flame sensor rod by the burner and clean the rod off with emery or fine sand paper then try it again. That often will completely solve the issue for that problem. If not let me know.All I ask is please use the star rating link at the top of your page before leaving to credit me through the site.
