What to do if Weber Q 300 Grill burners won't light or have a low flame?
- JJohnny HubbardJul 26, 2025
If the burners on your Weber Grill do not light, have a small flickering flame on HIGH, or the grill temperature only reaches 250°F to 300°F on HIGH, the excess flow safety device may have been 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 HIGH and wait at least 1 minute, then turn them OFF. Reconnect the regulator to the cylinder. Finally, turn the cylinder valve on slowly, and refer to the lighting instructions.
