The downside of Weber gas grills lasting forever is that every five to six years you need to replace the Weber Flavorizer bars.
You can use the links below to match your Weber grill with the correct replacement Flavorizer bars.
- 1 burner Weber gas grill
- 2 burner Weber gas grill
- 3 burner Weber gas grill
- 4 burner Weber gas grill
- 6 burner Weber gas grill
This site guides you between the different choices available, helps make sure you get ones that will fit your grill and provides a historical overview of the development of Flavorizer bars.
There are often two Flavorizer bar choices for Weber gas grills and sometimes a third.
- The least expensive bars are constructed from porcelain enameled steel. These come with a two year warranty but usually last for at least five years.
- The more expensive bars are constructed from 18 gauge stainless steel. These come with a five year warranty but usually last a few years longer.
- The third option you will might see are bars constructed of a very heavy gauge (16 gauge) stainless steel. These bars are not made by Weber but will probably last longer than your grill.
All three choices work equally well as far as enabling even heat distribution in your grill and preventing flare-ups. The main performance difference is how long they will last. Exactly how long the Weber Flavorizer bars will last depends upon how often you use your grill and whether or not you keep it covered.
I am currently cooking on four different Weber gas grills. If you would like to learn the nuts and bolts of these guys the links will take you to some detailed write-ups.
Remember, the only time you need to replace your Weber Flavorizer bars is when they have rusted through. If you are experiencing flare ups you might just need to clean the bars with a good scraping followed with a scrubbing in hot soapy water. Weber advises against using citrus scented dish soaps for cleaning Flavorizer bars; I assume there is a corrosion issue at play. It also is not a good idea to put the bars in the dishwasher as the amount of grill crud that comes off can clog the drain.
What makes the bars rust is the combination of heat and moisture. When I cleaned the Flavorizer bars on my Genesis 1000 the rust pattern was very interesting. The Genesis 1000 has 13 Flavorizer bars; five above the burners and eight below the cooking grate. The eight Flavorizer bars below the grate had the greatest amount of rust and corrosion. I also observed that the Flavorizer bars on the right side of the grill (the side that I use most often) had more rust than the Flavorizer bars on the left side of the grill. The bottom Flavorizer bars were exposed to greater heat and the top Flavorizer bars were exposed to greater moisture (dripping juices). The combination of hot and wet is what caused the most damage.
If you find you use one side of your Weber more than the other it is a good idea to rotate the Flavorizer bars every few months to help them wear out evenly. This will help prevent having to buy an entire set of Flavorizer bars just because one has worn out.
