When a gas stove burner won't turn off, shut off the gas supply or close the burner's manual shutoff valve immediately, then let the burner cool before inspecting it. The most likely cause is a faulty burner valve or surface burner valve that cannot close the gas flow. Remove the control knob and carefully try turning the valve stem by hand. If the stem will not rotate, or the gas burner stays lit when the control is in the off position, replace the defective valve. A cracked or broken control knob is another possible cause because it may not turn the gas valve stem fully. Inspect the knob for damage and replace it if needed. This problem is less commonly caused by a damaged knob with the same failure. These checks can help diagnose why your gas stove won't turn off or why a gas burner won't turn off. Enter your range or stove model number to find the exact replacement burner valve, surface burner valve, control knob, or knob for your specific appliance.
