Repairing a BBQ gas flow problem - how do i do it?

Question

I have a Charbroil Gas grill and the tank ran empty. Hooked up a new tank within 5 minutes and couldn't hear any gas flow and couldn't light the grill. Checked all of the connections and used soapy water to check for hose leaks...everything appears normal. I thought it might be the tank so I got another one and the problem still existed. Is there anything else I can do? Thanks for all of your help!

Answer 1

This is tricky. There is a safety shutoff valve in the connector that screws into the tank. It has a spring loaded plunger thingy that stops the flow of gas in the event of a broke hose.

It's suppose to self reset.

1) turn off all the valves on the BBQ.
2) turn off the valve on the tank.

wait a couple minutes..............

Now, turn the tank back on and wait for the gas pressure to equalize in the BBQ before turning on the burners. (30 seconds)

Now turn on one burner, and light.

I have a Weber gas BBQ, and replaced the "pain in the butt" connector.

Answer 2

The safety in the LP cylinder is called a "check valve" and it is like a swing-arm that gauges the amount of pressure when the vaporized propane leaves the cylinder valve. Leaving the tank the gas will push this swing arm out of the way and it measures the pressure.

When the manifold pipe fills with gas the pressure back-out to push the swing-arm back in place.

If there is a leak or if a valve is open when the cylinder is turned on the pressure leaving will be higher than the pressure returning and this causes the "springy thingy" to stop the flow of gas.

Usually when this happens it is with a newly filled cylinder. The Overfill Prevention Device is a float in the liquid propane and the float displaces part of the solid mass so the pressure "hits" the check valve swing arm a little bit too hard.

Then the returning pressure is restored lower even though it is correct and the tank shuts down -- because the float is creating pressure we'll usually get gas but not enough to cook.

Similar to the message above, reset the check valve by turning everything off but then disconnect the regulator from the tank valve.

With the tank disconnected, turn on all the BBQ valves for about 2 minutes to release any residual pressure.

Turn all the valves off, reconnect the regulator to the tank and turn the tank on very, very slow for the first full 360 degree turn.

Releasing the pressure by removing the regulator resets the check valve and releasing residual pressure ensures the next connection does not "go into check". Turn the tank on very slow when it is full so the float does not push the vaporized propane through so hard the swing arm registers incorrectly.

It sounds like the regulator went bad. Order one from their web site.
