When your Gaggenau gas stove burner won't turn off, the most likely cause is a defective burner valve or surface burner valve that cannot close the gas flow. Turn the control knob to Off, then remove the knob and carefully try rotating the valve stem by hand. If the stem will not move, or the burner remains lit when the control is in the Off position, the valve should be replaced. A damaged control knob is the next possibility. A cracked or worn knob may turn without properly engaging the gas valve stem, leaving the burner on. Inspect the knob for damage and replace it if needed. The less common possibility is a separate knob with the same type of failure. Do not continue using a gas stove burner that stays on, and shut off the gas supply if you cannot stop the flame safely. Enter your Gaggenau model number to find the exact burner valve, surface burner valve, control knob, or knob replacement part for your specific gas stove.
