If your Bosch gas stove burner won't turn off, turn the burner control to Off and shut off the gas supply if the flame continues. The most likely cause is a defective burner valve or surface burner valve that cannot close. Remove the control knob and carefully turn the valve stem by hand. If the stem will not rotate, or the burner stays lit in the Off position, the valve is likely faulty and should be replaced. A cracked or broken control knob is the next possibility. The knob may turn without moving the gas valve stem, leaving the gas stove burner on. Inspect the control knob for damage and replace it if needed. These checks address common gas stove won't turn off and gas burner won't turn off problems. Before ordering a Bosch burner valve, surface burner valve, or control knob, enter your model number to find the exact replacement part for your specific gas stove or range. Disconnect power and shut off the gas before servicing, and have a qualified technician handle repairs if you cannot safely access the gas components.
