Weber · Spirit Grills
If the grill burners fail to ignite, the problem could be due to the activation of the excess gas flow safety device or an issue with the ignition system.
Click steps to track your progress.
Reset the excess gas flow safety device by turning off the LP tank valve and all burner control knobs, waiting five minutes, then restarting.
Attempt to light the burners with a match as described in the manual's 'Lighting with a Match' section.
If match lighting is successful, troubleshoot the electronic ignition system by checking its components and battery.
Ensure the LP fuel tank is not low or empty, and refill if needed.
Inspect the fuel hose for any bends or kinks and straighten it.
