Thermador Gas stove burner won't turn off

When your Thermador 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 and, if the flame remains lit, shut off the gas supply and have the appliance serviced before using it again. After removing the knob, you can carefully check whether the valve stem rotates by hand. If the stem will not turn or the burner stays on in the Off position, replace the faulty Thermador range valve or surface burner valve. A cracked or broken control knob is less common but can also cause a gas burner not to turn off because the knob may no longer engage the valve stem. Inspect the knob for cracks, a stripped center, or other damage, and replace it if needed. These same checks apply when a gas stove won't turn off or a gas stove is not turning off after cooking. Enter your model number to find the exact replacement valve, surface burner valve, or control knob for your Thermador gas stove.
