Unhappy My Propane is not Flowing.....

Need some advice here....
Was getting ready for a short weekend out and was not able to get the fridge to fire off on Propane. Did the usual bleed at the stove but was not able to get it to light either. Urggg. Went on weekend and had a blast without it. Ran the fridge and hwh on electric and all was good.

A couple weeks later when I had time to fool with it I noticed that if I turned the valve on very slowly and only about a half turn, I could get the stove to light but with only about half flame. Fridge did not want to play at all..... If I turn the valve on normally I could hear a small click as if a check valve then nothing.... no gas at all. Cleared the pigtail and tried again turning the valve on very slowly again. Small noises of the gas flowing can be heard then and still only half flame at the stove with fridge still no go.

Filled both tanks on the weekend. Tried to explain it to the guy and he says it may have been air trapped in the tank and that his bleeding it off and filling it should correct my issue..... no cigar for him..... tried all again when I returned home with the same result.

From what I read in here I'm guessing maybe I should try a couple new pigtails? Really?? they go bad in only 5 years? Hmmm.

Any advice appreciated.

If you had the tanks off, the lines are depressurized and empty. You need to turn valve on very slowly for first 1/4 to 1/2 turn. Wait 30 seconds after you hear first gas flowing then turn tank on as normal. If the lines are empty ( tank removed) and you turn the tank on quickly, a large amount of propane flows into the empty lines to pressurize them. This causes the open flow sensor in the tank to activate cutting off flow. Once activated, you need to shut of tank, disconnect, let sit for a few minutes, then try again turning on very slowly.

Sounds like ya answered your own question. I would check the little fitting in the end of most pigtails that has a check valve in it. Some you can replace just the check valve or take it out entirely like some have done. They seem to go out pretty often. Next to check if that doesn't fix it is the regulator, then the tank. Good luck!

Ok. Thanks. I'll try it again. I thought I did that. After turning it on slow for a half turn and hearing the flow tick and ping, etc. when I attempt to turn it all the way it kicks off. Perhaps I didn't wait a full 30 seconds though. I'll fool with it more this afternoon and see what I find.

If you are opening the valves slowly and are experiencing the same thing with both tanks then it is more than likely the regulator that is defective.

If that exercise doesn't work, do this; disconnect the tank(s) turn them upside down and bang them on a piece of plywood laying flat on concrete. The sudden jarring motion will release the flow sensor. Sounds dangerous, but its not, because you are banging it on the protective collar/handle.

Resort to this procedure, if Flybobs' suggestion does not release the internal valve.

X2. Both tanks triggering the internal flow valve at the same time does make it more likely its your regulator not operating properly.

Thanks for all the feedback.
Starting another work week today, but I'll get back to the troubleshooting as soon as I can...
I'll try the upside down bang in case the valve in the tank is the culprit.

Inclined to agree with a bad regulator as both tanks behave the same.
Are they pretty standard? Can I order an RV propane regulator on amazon or do I need to be specific?

I'll get back on in a few days after I've had time to check it out more.

Thanks again.

You can order a Auto-changeover regulator from Amazon if you'd like. Here's a search for them.

Your 5th wheel will also have a second regulator at the off side cylinder, but you shouldn't need to replace that on unless you want to.

I'm late to the party but here's some thoughts from my experience.

1. If you activate the high flow preventer in the tank I'm pretty sure you
can simply shut off the tank and wait a few seconds and try again.
I don't believe you have to disconnect it.

2. Yes a pig tail can go bad in 5 years! When one of mine went bad I bought
a pair and was surprised at the difference in flexibility. The old ones had really
gotten stiff compared to the new ones! The check valve in the pig tail can go bad at any age.

3. The camco regulator has a -tiny- red/green tell tale window and is harder
to see than some of the other brands. It's an OK regulator just hard to see
what color the "flag" is.

Good luck with your problem! Be careful and be sure your fittings are
tight and checked for leaks when you finish!!
