When burners produce a small, flickering flame even at the high setting, it suggests insufficient gas flow or obstructions.
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.
Check if the LP fuel tank is low or empty and refill it if necessary.
Inspect the fuel hose for any bends or kinks and straighten it carefully.
Clean burner ports that run along the entire length of the burner tube as per maintenance instructions.
