Propane--no gas going to range

Kansas couple wrote:
Was having difficulty getting range burners to light. Once I got one to light the flame lasted only a minute or two and slowly died down to nothing. Checked my tanks, they both felt light so very likely empty. At this campsite I was running the refrigerator and water heater on electric, so no problems there. I did a tank exchange and put the full tank on the tongue. Turned regulator to that one and opened the valve. Still nothing. Waited a while and tried again. Still nothing. Didn't even smell gas when I turned the stove burners to "light" position.

I plan to exchange the other empty tank soon and give it another try once I return to the campsite. (I keep it at a permanent campsite about two hours from my house.) Since coming back from the weekend camping trip I've been reading up on propane lockout and will certainly open the tank valves slowly next time. Any other input or suggestions? I'm hoping I don't need to replace the regulator but that might be the next thing if two full tanks don't do the trick. Regulator is original to the camper (bought new in early 2014). Tanks do have a cover over them.

Thanks in advance!

Try this.

Start your fridge on propane. Make sure it’s running on propane and then while it’s running go turn off the tank(S). Once the fridge quits (you’ll be able to tell by the igniter trying to start it) then go to your range and turn on a burner wide open. Go back to your bottle and turn it on slowly preferably while somebody is trying to light the burner. If it lights you are good to go. Your range just locked up probably because you turned the bottle on too fast. This happens to us.

Hope that helps.

Happy camping.
