BBQ was working great last time I used. Next time there was no gas flow when I turned it on. Yes we have gas and it is connected to the large tanks for my furnace. Is there an automatic built-in shut off?

Check that the gas jet is not partially blocked limiting the amount of gas out. To up size my bbq to a hotter flame I used oxy welding set tip drills and gently opened up a size. worked a treat and cooked quicker. maybe you can get next size jets for your problem. check that the regulator is not restricting the gas flow.
yes the control knobs are what controls the heat, its a saftey thing on the bbq so turn off tank undo gas from tank open knobs release gas from line , turn off control knobs , reconnect gas line to tank ,turn on slowly , turn control knobs to on and light,
It could be a defective LP gas regulator or a restriction somewhere in the gas line for the bbq. This can also happen if the propane tank is overfilled.
First make sure that the LP tank is not overfilled. If you open the bleeder hole on the tank(small screw next to the valve) there should be no liquids coming out. If liquid propane is coming out then the tank is overfilled. Keep the bleeder screw loose until the liquid disappears then tighten. Re-connect the tank and see if that fixes the problem.
Then inspect all the gas lines on the bbq. Make sure that there are no kinks or crushed lines.
Then take a look at the gas regulator. Try turning on all the burners then give the regulator a couple good taps on the housing with something solid. See if the burner changes size. If it does and then goes back down it could be the gas regulator. Also take a look at the regulator housing. There should be a very small hole on the housing and it might be labled "vent". Make sure that this little hole is not plugged with any debris or that can cause a low pressure problem. You can use a sewing needle to gently poke out the hole. You will know if it worked because the burners will become much higher. And you could also try disconnecting the hose and regulator assembly from the bbq then turn on the LP tank slowly with the regulator connected. You should get plenty of gas flow from the end of the hose. Then use your hand to block and release the flow a couple times to try and clear any debris that might stuck in the regulator.BE VERY CAREFUL DOING THIS!!! MAKE SURE YOU ARE CLEAR OF ANY SOURCES OF IGNITION BEFORE TRYING TO CLEAR THE REGULATOR. Then reconnect the hose regulator and tank to see if the problem is fixed. If you are getting very low flow from the hose with the regulator disconnected then it is probably a defective regulator. They are pretty standard and you can purchase a new LP hose and regulator assembly from most home improvement stores.
If the regulator checks out good then I would think that there is a restriction in the main gas line for the bbq after the regulator. You will need you dis-assemble the main line and blow it out with some compressed air to clear the restriction.
Turn gas tank off and disconnect connection fron tank valve. Re-connect and turn gas on. Check for leaks with soapy water solution. Tighten if needed. Some regulators will detect leaks and cut off gas.
Hello. The conversion of any gas appliance usually requires changing orifices, regulator and burner. Then once those changes are made you can adjust the gas flow. The difference in the orifices is this.
Natural gas orifices are larger than liquid propane orifices simply because the gas pressure for the natural gas is lower.
I would double check to be sure that you have installed the correct orifice. Also, you can adjust the amount of gas by turning the orifice in or out, using that socket.

Couple things could be happening here. If you do exchanges, have you used more than one different propane tank since you've had this issue? This eliminates the possibility of a low tank pressure and a faulty tank connection.
Next you need to look over the burners and the propane flow tubing. Spiders LOVE the sweet smell of propane and make their webbing inside the piping that get's the propane up to the burners. At your flow valves/On/Off knobs you'll notice that the propane shoots from the valves into a pipe with an air gap to gain oxygen. Look in there to see if there's any webs. Also should be a gap were that piping meets the burners, so you need to look there too. Depending on the age of the grill, you need to look the burners over. Corrosion & rust can cause the flame/propane holes in the burners themselves to cake up and close up causing much less flaming/heating opportunity. Also depending how much you've used it, it could be grease/dripping/sauce caked up over them too so they may need to be detailed/cleaned. It's not a pretty job, but grill maintenance that should be done every spring. When the burners get caked is when it's really fun and you need to remove them and clean out the holes with toothpicks. Jenn Air makes quality products, but being a BBQ and outdoors, it's just as vulnerable as any other to elemental and use issues.
One last thing to check, some regulators (the disk shaped part right where the hose attaches to the tank) have another air mixture intake there with a screen on one side. Make sure there's no water in it and the opening is face down if you have one like that. Otherwise it's restricting the flow of the propane. I haven't seen one of these in a while, but they're still out there so check it too.
this is actually how every gas stove is set up and yes it would be a safety issue but there is really no way to change how they work i do wish the people building them would do it with at least a timer or something but that would make the product much more expensive. same type of technology is also used on propane bbq grills btw. it is just something you get used to after a while i have had gas for the last ten years and dont even notice it now
