What to do if Weber SUMMIT S-670 Grill burners do not light?
- RRobin BakerJul 26, 2025
If your Weber Grill burners aren't lighting, or have a small flickering flame, or the barbecue temperature only reaches 250° to 300° in the “HI” position, the excess flow safety device may have activated. To reset it, turn all burner control knobs and the cylinder valve off. Disconnect the regulator from the cylinder. Turn burner control knobs to “HI”. Wait at least 1 minute. Turn burner control knobs to “OFF”. Reconnect the regulator to the cylinder. Turn cylinder valve on slowly. Refer to “Lighting Instructions”.
