I recently changed the regulator on my 2002 Weber Summit 450 propane gas grill. It finally gave up the ghost after 20 years of good service. How did I know it had gone bad? I wasn’t getting good gas flow to the burners, despite the burner tubes being clean inside and out and the valves all in good working order.
The good news is that it’s easy to get a new regulator, just call Weber at 800-446-1071 and they’ll tell you which part number you need for your grill. They’ll even be happy to sell you one!
I shot a short video that demonstrates just how easy it is to change the regulator in this grill. Enjoy!
