I can't say thank you enough about how much Weber Customer Service helped me on Thurs Aug. 28 when I was having trouble with one of my burners on my Spirit 310. The crossover tube was clogged and when I called the first time they explained I could clean it by taking it apart and that it would be easy. I started the process and sure enough it was very straight forward. I did have a problem getting the burner knobs to come off and rather than breaking them I called again. The help and encouragement was provided quickly. Then when I got to the point of pulling the burners out, I was concerned I would damage the the tube which seemed to be set firmly at each end in the front and rear burners. But, once again it was Weber to the rescue. The BBQ is fixed and running great! Thanks Weber!
