I have a problem with the propane on my 5th wheel (2019 Montana High Country )I just bought the unit second hand and have never used the propane system before. When I turn my bottles on, then go inside and try to light the stove, I get a short (1 second) hiss, and then no further pressure. If I let the system rest for half an hour and turn it on again, I get another 1 second hiss, then no more pressure. It appears that there is only a tiny bit of gas coming from the cylinder. Things I've tried:1) The cylinders do have propane in them, I estimate about half full. When I unscrew the green pigtail fitting, I get a hiss and a little burst of propane. Also the regulator I have shows red when there is no propane, and green to indicate sufficient pressure, and it's green when switched to either of the two tanks.2) I've tried turning off the gas, unscrewing the pigtails, letting the system rest for 15 min, and then assembling again, turning on the tank VERY slowly, but no difference in the outcome. Very minimal hiss from stove for 1 sec, then no pressure.3) I checked and tested the propane leak detector, it displays the green light indicating it is working properly. I don't see a solenoid anywhere that this leak detector would be operating, but I did check it just in case. Do you have any ideas of what I should try next? The RV is only 6 months old, so I can't imagine the regulator would be bad. I bought it from previous owners who had free electricity at their RV park, so the previous owners never used any part of the propane system.Thank you!Randy

The only thing left is a faulty regulator. Either have it checked by a qualified gas fitter or just replace it.

Sure sounds like a bad regulator to me. Amazon has them pretty cheap

Your propane tank may have some pressure in it, and may appear to be half full, but it doesn't have enough pressure in it. I had a similar problem with both my propane tanks on my Montana High Country, bought new last September. It wasn't until I took them to be refilled, even though I didn't think they needed filled, that everything started working right. I took the propane tank to be filled at a different dealership than were bought, and they purged the tank and then refilled it. Both worked fine and the flow was fine after that.Edit:Except then I had a slight gas smell for several months and could never figure it out. After about the 7th or 8th fillup for each tank, it quit smelling. Best I can figure, the connections had small imperfections in them that allowed some seepage. After connecting and disconnecting many, many time, it must have worn down and sealed correct. That's the only thing I can think of that would have caused the smell. Perhaps the slight leakage caused the tank to have less pressure as it leaded the pressure off? I don't know. All I know is, after they purged the tank, I had flames!

I’d skip the checking and just replace.

Thank you so much guys! DutchmenSport, your post about just purging/filling the tanks is comforting. I will try that first. It's possible the tanks are lower than I think. If that doesn't work, I will try replacing the regulator as per the other gentlemen. Thank you again everyone! I'll keep you posted on what works.Randy

Been thinking this same thing from the beginning.

Replace the pigtails at the tank. They have a high flow valve intended to shut the gas flow off in the event of some type of high flow failure. These high flow valves can go bad. I had to replace mine after two years. Like you I thought it was the regulator. It wasn't.

Well, I was able to take the hose off, untwist it, and put it back on. And what do you know! The stove WORKS! The hose is still somewhat kinked and I probably should end up replacing it, but it works for now. I used a leak detector and don't detect leaks anywhere.

THANK YOU GUYS! You really saved the day. I appreciate so much every one of your comments. You helped me tremendously.

When I need new hoses I go to my local propane dealer. They will make up any length I want with what ever ends I need. I never buy anything propane related from an RV dealer.

Ok folks! The saga continues!

I got the new regulator and installed It. Tested indoor and outdoor stove again and still same behavior. No good.

So I started testing every single other appliance. Earlier, After testing indoor and outdoor stove and neither worked, I had thought it would be in vain to test anything more. But I did today and lo! The gas water heater roared to life! You guys told me so. I was so foolish for not checking that earlier. .

So I started checking every inch of the hose in the slide that feeds the kitchen stove, and lo! In a hidden spot there’s a horrible kink I didn’t see. Just like the gentleman above suggested. If i hadn’t been so rushed I’d have seen it before.

So! I probably didn’t need to replace the regulator at all, but oh well. Chick it up to life tuition for my foolishness.

Anyway, this hose is linked really really badly. Is it best to loosen the hose and try to tighten it back with some opposite twist, or just replace it? If so where does on buy a replacement, and look up the part#?

Still don’t know what’s wrong with the outdoor stove, but indoor is most important.

Thanks so much guys!

Randy

Personally, I'd see if the hose could be re-routed so that it doesn't kink, then replace the hose with a new one of a different length, if necessary.

PS: I always try to be sure to turn the gas on extremely slowly, so I don't think that's the problem....

Thanks!

Thank you everyone so much for your comments!

So I drained and refilled the tanks. The guy who vented the tank said the contents of the tank looked weird - he said normally propane vents as a white mist, but mine vented as a clear-ish mist (!?!). Perhaps there was something bad in that tank that gunked up my regulator???

Anyway, connecting the refilled tank slightly improved my stove function. It will now run sporadically, but only just barely. It now will sometimes stay lit if I put it on the highest flame setting, but even when set for max flame it produces only the tiniest flame possible without going out. And often it simply doesn't light at all.

I've checked other appliances - such as the outdoor stove - and none of them light reliably either.

So I ordered a new regulator from Amazon. Should be here by Wednesday and I'll report back on whether that fixes the problem!

Thanks!

If you just turn on the propane valve and its to quick, it will set the emergency valve on the tank. Turn off the valve on the tank, let it set a few seconds and turn on slowly. Turn it off and do it again. This has happened to me on most every rv I have owned over the past 30 years. Again, turn off the propane on both tanks also make sure your valve near the regulator is turn the proper direction. It should be able to be set to one tank or the other or both tanks. Regardless, pressure is my be on tripping the emergency valve on the tank or the the valve is set wrong by the regulator. Sorry folks for any bad grammer, we are out camping and hard to see on phone!
