A common mistake is assuming that the tank valve (to which the knob is attached) is closed. It may be already open to the maximum, which means that trying to turn the knob counterclockwise to "open" the valve to let the gas flow to the appliance is not possible. Forcing the knob in any way will usually result in breaking the metal at the base of the knob, rendering the knob useless. Before trying to turn the knob counterclockwise, try turning it clockwise to make sure the valve has not been fully opened. Use a cloth wrapped around the knob and slip joint pliers to gently push the knob. Don't use excessive force or you may damage the knob. If you are sure that the valve is closed, but can't be turned counterclockwise, use a penetrating oil, applying liberally at the point where the valve/knob shaft goes into the valve. Keep the tank upright and wait 15 to 20 minutes before attempting to turn the knob again. If all this fails, you may be forced to have a propane expert replace the valve and knob, or buy a new complete tank.
