While Weber is most known for their line of charcoal grills, they also make a large variety of high-quality gas grills that are popular with consumers. If your grill isn't heating up all the way or you have uneven heat, the burners are most likely the problem. Here's a walkthrough to help you confirm that the burners do need replacement as well as how to do it.
Do the burners need to be replaced?
The first step is to make sure your burners are in fact beyond repair. Start by making sure the propane tank has enough fuel then look for leaks in the fuel hose by using a solution of water and dishwashing liquid. If you see bubbles in the solution, there's a leak in the line. In this case you'll need to order some affordable replacement grill parts to fix the leak. Next, try lighting the burners to high for 10 minutes. Check the spider screens for any blocks that may prevent propane from reaching the burner itself.
You can also try resetting the excess flow safety device. To do this, turn all burners off and turn off the valve on the propane cylinder. Disconnect the regulator valve, turn all burners to high and wait one minute. Now, turn the burners off again and reconnect the regulator valve. Turn the valve on the tank back on and test the burners.
If these steps didn't work you'll need to replace the burners of your grill. Here's how to do it.
How to Replace Weber Grill Burners
1. Get the right Weber grill parts. You'll need your model number to make sure you order the right burners. You can either order grill parts online to save money or see if your local hardware store has them in stock.
2. Now, turn off the valve on the propane tank and disconnect the cylinder, removing it from the tank, as well as the cooking grates and flavorizer bars.
3. Remove the control panel by taking out the screws holding it in place.
4. Loosen the burners by turning the nut underneath with a pair of pliers.
5. Pull the burner up at an angle to remove the burner along with the tube assembly.
6. Insert new burners in the same position and make sure the burner tubes fit inside the venturi tubes behind the control panel. The burner tubes don't actually attach to the venturi tubes but should be at least 1/2″ inside so they don't become disconnected if the grill is bumped.
7. Reattach the locking nut under the grill to secure the burners in place.
8. Reattach the control panel and put the cooking grate, flavorizer bars and propane tank back in place.
9. Reattach the propane gas regulator to the valve and turn it back on.
That's all it takes to replace the burners on your Weber grill. While Weber grill parts are made well, all burners eventually wear out and need replacing. Make sure you order the right parts and you'll find it's easy to do the work yourself and save money without buying a brand-new grill.
