Philip T Millville , MA July 07, 2015 Rings dried and cracked Thes rings degrade over time due to heat and will eventually crack and dry out. Replacing them with new ones doesn't take much more than a few minutes. I just unscrewed the burner caps to expose the rings and dropped in the new ones. I recommend replacing all the rings at the same time vs just doing one or two. 2 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
