Furnace or propane trouble

Hi everyone,

I'm really hoping someone can help me with my problem.

I have a 2016 jayco trailer. Its permanently hooked up on my property to 30amp power and has a full lp gas tank permanently attached too.
Up until yesterday I had no issues with the furnace or lp gas. We've had a few really cold days, waking up to -4 again this morning.
Propane is full and on. I can light the stove, it burns perfect for about 3 minutes and then goes very low and keeps burning like that. If I turn it off a few minutes it does the same thing, burns great and then burns very low but does stay lit.
The furnace blower kicks on but didnt seem to want to heat. Now itll keep running, barely putting out heat, and after running for about 4 or 5 minutes, trips the power for a few seconds before starting over again.
It feels like its blowing slightly warmer than cold air, if that makes sense.
The hot water heater sparks as it's trying to ignite but then the daily fault light comes on and it quite trying.

It seems like the gas isnt flowing properly. Yet everything was working fine a couple of days ago, and nothing has been moved or messed with.

Any suggestions would be so greatly appreciated.

Thanks,
Shilo

turn your lp tank off then open valve very slow. maybe will help .. maybe excess flow shut down .. give it a try ...

Mojim, I tried that, but it hasn't seemed to make any difference.
Just a question...would that still be an issue if the propane tank hasn't been turned on or off and it was previously working fine ? I could understand if they just filled the tank and turned it on too quickly, but it was working fine since the last fill up. Is the too high flow a common issue that can just randomly cause problems ?

Excess Flow Device comes into play when there is a sudden high flow situation.......opening service valve too quickly or a major leak downstream


I think your Regulator is the problem.
It is NOT maintaining system pressure based on demand

Your last fill up may have been a mix with more butane.

You can try warming up the propane tank.

At -4 your not going to get a lot of flow. Stick a heating pad on the tanks and keep them covered.

not common I was taking a wild guess sounds like maybe regulator try pouring some water over it to warm it up if its cold out. some times frost can get in on diaphragm sometimes just a tap on reg .. if that don't work maybe take reg to propane supplier to check or replace.. good luck

Thanks for all the input, folks ! It looks like it must be the cold afterall. Since its warmed up to a balmy 22, the furnace is firing and heating up as it always had.

What do you guys in colder climates do in the very cold ? Blanket the propane tank and regulator ? That wont cause any other issues, will it ?

Regulator is the issue


Tank is not a problem in cold temps


Wrap some insulation around regulator

Tank size can be a problem it takes wetted surface area to vaporize propane heck even color of tank !

How old is the regulator?
Could have gotten some propane with moisture in the tank
In cold weather they add methanol to the propane to keep it from freezing.

Regulator is 3yrs old. Tank is 120g white horizontal.
Yesterday, once it hit about 10 outside the furnace was working like a dream again. Could the regulator still be bad or just likely for some moisture in ?
