Propane Regulator Frozen?

I know some regulators can freeze up as we had some vehicles that were propane powered and at times in the winter we had to pour hot water over the regulator.

I NOW have a happy ending to my problem. I had a suggestion that I remove the tank and tap it on the ground as a check valve ball may have been sticking and then open the valve slowly. I just went out and removed my tank then banged it twice on the driveway. I replaced the tank in the RV, hooked up my pig tail, I then opened the valve slowly to make the regulator think I didn't have a broken line and the site glass on the regulator turned green. I then lite my stove top and furnace and all is well again.

Last winter I was blow apart at the suggestion that an RV regulator could freeze up in extreme cold, as I've seen home (city) gas lines between the gas meter and the house freeze several times in my lifetime (the regulator). So ya, I still stand by my own experiences. It could be frozen, especially if there was water vapor in the mix. Get an electric heating pad and wrap it around the regulator and let it warm up. See if that helps.

Sorry for posting originally in the wrong section.

If the regulator is more than five years old... just get a new one.

May as well get new pigtails too.

Location?

I've read on these forums that fuelers in southern states cheat and fill cylinders with inferior butane instead of actual propane. Butane turns liquid at -1c, which can be trouble in cold weather.

Try pouring some cold water on the regulator.
