propane no propane

[Bill340]

Todays problem, We have a 2006 Dynaquest 260, we love this little bugger, just returned from a month long trip, Half way thru we lost our propane to the ref, AND the hot water heater, now the furnace runs on propane and the tank is full I ASSUME that the regulator is working as the furnace gets gas, we have no propane stove, just hot water,, ref.. furnace. Thoughts??

[rockfordroo]

Just to be clear: How do you know the furnace is getting gas? Is it getting hot and running for more than a minute or two? If not, it may NOT be getting gas.

[Bama Rambler]

If you're sure that the furnace is running, your description screams crimped line to me. especially since it was working and then it wasn't.

Do you know plumbing routing wise how the appliances are located in the line?
Is it cylinder > furnace > water heater > fridge?

[steve32409]

if you have propane and some things work - then you just have to see if you turned off a gas valve to that appliance or the gas valve in the stove quit working - just unscrew gas line nut to stove a little and see if gas is present.

Here's a crazy for you. May not apply but I've seen some crazy things in TT's.
Make sure you haven't blown a 12 volt fuse. The furnace won't run on gas & the fridge won't run on gas without the 12 volt hooked up.

have propane to the furnace, turned the furnace on today lit right away blew heat, tested the lines for the water eater, no gas, checked everyfuse I could find all ok, have 12v to the fridge,ok, have voltage to the gas valve at the water heater, Have no gas stove, found in all this crawling around, behind the wall under the sink there is a 3in by 4in white plastic box with wires 4 on the bottom plug one red on the top, I think I could read something about a mother board, I know its linked some how. keep throwing Ideas I will keep trying..Thanks for all your help.

Any chance your Propane/CO detector turns the gas off???

-------------------------------------------------------------------Gas lines don't work like that , If you have gas ? and the gas tank valve is open - then all lines are open to the different appliances , fuses don't stop gas from going to each place. ( I would check your furnace again for flame and not just heat blowing - this is summer so make sure you have fire there)

[steve32409]

on second thought - if you ran out , and then filled up - I just think you have air in the lines , so just keep trying to start things to get air through

[Bill340]

went to get propane just in case, only took 1 gal, ,its full was working fine one day, drove 150mi and turned on again no hot water or propane fridge,Started the furnace stood out side after a little the burner ignited and heat came pouring out of the exhaust, furnace works,

[Bill340]

Tried turning off the co2 detector then restarting it, it chirps when starting as always then just goes to blink as always.

[steve32409]

problems like this intrigue me , but think it is something simple because only furnace works - like the rest are on a separate line that was turned off ? check real good around propane tank for the line or lines and a turn valve on the line to shut off - good luck

[Bill340]

found the valve, its on seems the tank feeds an iron pipe that t s off to the furnace the disapears under the foam they use to glue everything together underneath,

[steve32409]

ok , then tee's off somewhere under the foam to all other places . you need to unscrew the gas line connection fitting at the water heater or back of frig ( probably outside panel ) and see if gas starts coming out ( or some sort of trash ) stuck in line and go from there ? but be ready to turn tank off or re-attach fitting real fast ! ( and not while smoking , lol )

[Bama Rambler]

Our RV propane is plumbed like that too.

There's a black iron pipe running down the curb side of the unit frame and it tees to the furnace first. At that point I think it changes to copper tubing and that tees to the rest of the appliances.

Checking for gas by unhooking the lines is one way to tell if there's flow, but be sure to turn both the 12 volt and 120 volt power off to all the appliances. You really wouldn't want the water heater or fridge to try to ignite just as you got good flow out of the disconnected line.

X2!

[steve32409]

Correct , be careful and if working with electricty or gas is out of your comfort zone - either get help or hire someone who understands it all .

[Ian Walker]

I've been thinking about this all night & of course don't know your situation. Check if the hot water tank valves are in bypass for
winterizing. You are getting gas to the furnace.

[Bill340]

I was on a trip so it was being used then the next rv park, it didnt work, I can hear the click for the main valve to open when I flip the propane switch on, Gas to the furnace just NO gas to the hot water heater or the propane side of the fridge.

///////////////////////////// co detector has absolutely nothing to do with it . check for gas at the appliance
