Please try turning the valve in both directions, occasionally the valve will be stuck in the open position. Because the gas can't escape unless engaged with the pin in the regulator, you should still be able to use your tank. If the valve is still stuck, a small bit of oil such as WD40 or cooking spray, applied to the stem should help loosen it up. Do not use any tools since too much torque may result in the valve breaking off. Please let me know what happens.
Do you know you have a full tank, but aren't getting any gas to flow to the grill?
There are a couple of explanations for either low flame, causing your grill to not get very hot, or no flame at all.
What's probably happened is the regulator may have been tripped by a rush of gas through the gas lines of the grill. This is usually caused when the tank is hooked up and the grill dials are on high before the valve on the tank is opened.
The OPD valve found on your tanks has a safety geature that restricts the flow of gas when the tank has been opened all the way, or if the burners were turned on before the tank was turend on. It does its job thinking there's too much pressure and slows down or completely stops the flow.
One trick to keep in mind here is that you should always turn the gas valve (at the tank) on before turning the grill dials on.
To reset the regulator:
- Close the tank valve
- Disconnect the tank from the grill
- Turn all gas knobs on the grill to high for 1 minute- then turn back to the off position
- Reconnect the tank
- Open the valve on the tank
- Turn your starter knob on the grill to "high"
- Ignite the grill
- Return to grilling!
