3rd night out and furnace quits

[DeanF]

New 2014 FR Crusader 5th wheel, hope it's something simple I can fix.

I did run it out of propane. but filled my bottles and when we set up it worked fine for a while then suddenly quit blowing. So I turned it off and back on heat and blowers came on but no heat.

At first it quick cycled the blower. I tried to remember how to reset the thermostat I think the tech said hold the on off button and the + key at the same time. The display showed 2 dashes. Turned the system to heat blowers came on but no heat and stayed on until I pulled the fuse.

Help... cold with my wife who was leery of the purchase to begin with.

I would make sure your gas is working first. Lite up a burner on your stove for a couple of minutes. Then try your furnace again. Some furnaces need 5 to 10 minutes in between if they don't lite up.
Hopefully you can get it working. We always carry a small space heater with us to use also.

stove works thanks.

Try cycling the breaker to reset the board in the heater. Leave the breaker to heater off for 30 seconds. Then back on. Should try and lite 3 times or so and if still no fire it will lock itself out again. When there's no trial for ignition and it just defaults the blower on that's a dead giveaway it's in a lock out. Goodlyck

I had a similar problem on my TT after running one of my propane tanks out of gas. I had it filled and put it back in service but couldn't get the furnace to work. The stove worked but appeared to have a low flame. After messing about with the thermostat and breakers for a bit I went and looked at the propane system. All valves were open and I knew the tanks were full so I cycled the auto-changeover valve on a whim and it worked fine after that. Apparently it was sticking partially closed.

Buy a few lasko electric heaters as backups from Walmart.

I ran my gas furnace out of propane last fall and had a heck of a time getting it to re-fire. Took most of an hour to get the air out of the line and working again.

Also shut both propane tank valves off wait a few seconds the very sloooowly turn them back on.
Since you ran tanks out of gas the lines were empty.
Its VERY possible when you turned the valves back on the fast surge of gas popped the opd valves on the tanks.
Doing the above mentioned will reset them.
Issue's always seem to arise when you run out of gas so try not to run out.
I'm not sure why your rethinking your purchase when your not even sure if this is a equipment failure or operator error.

Good luck

Turn valves on very slowly especially if the system has run out and has
no pressure in the lines. (It's that 1st teeny bit you move the handle
that we're talking about. After you've got it open a 1/4 turn you can
proceed as normal.)

As the furnace is 12 volts it would have a fuse and not a breaker.

Correct 12v only.

Yep got me twice before I figured it out. Open valve so slow, you should hear a little squeal as the lp starts to flow. When noise stops, pressure has equalized and you can open it on up.
But if stove flame is normal height this is not you problem. Check flame with all burners on. If flames are strong, ?????

I had it happen "ran out of fuel" and installed full tanks and consequently opened valves to fast then popped opd valve.
Stove burners still worked but a lower flame.

Did as I said in previous post and all was fine.

I believe that your gas line may still have air in it and it will take a little time to purge it out. You ran the gas lines dry or the pressure fell so much as not to push gas back to the furnace. Several attempts will have to be made to get the flames going. The fan will always come on for a time before the flames come on. Even with flame at the stove, there is more than likely pockets of air in the line to the furnace. Keep working with it and it should be fine.

Oh yeah brain fart. Pull the fuse!
