Fridge won't work on LP

We have a 2014 23' FB. It has been stored indoors since our purchase in Nov of 2014. On our maiden trip today, the fridge will not work on LP. Battery is in use mode, propane tanks are full, stove lights and burns properly. When the fridge is turned on in auto mode, the check light comes on in seconds. I tried the suggested method of turning it off and on three to four times. I opened the outside access and checked the value. It is open. I have not tried it on AC as there are no hook-ups at the campground. I do have a 2000 watt generator available and could try it that way. Any ideas, or do I just have a problem that needs service? It is still under warranty. thanks for any advice.

Burn a stove eye a few minutes. It helps purge the gas lines of air.

I would first fire up the genny for a while and see if it starts to get cold. If so you can then begin to narrow it down. When I have problems like this (and it has happened a couple of times - I even carry coolers with me just in case...) it is quite often a dirty burner. Soot can fall down from the flue and clog it very easily as it only has a very small flame (kind of like a candle). That is where I would start (not with it hooked up and running on AC though!). Of course yours is new so it likely isn't dirty. But yes it will likely need to be serviced/checked out by a dealer. I think the fridge has it's own warranty and can be checked by any authorized dealer of that brand IIRC. CRH is right about firing up the stove, but it sounds like you already did that.

Another area to check is the flue. Sometimes a spider will enter and spin a web which will prevent the draft from flowing through the vertical tube (chimney flue). You may be lucky with a coat hanger inserted in the first few inches.

You need to be careful as there is a wire that drops down from the flue top on which there is a thin, twisted aluminum ribbon that causes just enough slowing of the draft to heat the chemical mixture in the small tube mated to the flue.

The proper way to clean the flue is to remove the refrigerator, then the baffle from the top of the flue, and use a brush similar to those used to clean rifle barrels. Anytime your trailer sits for long periods, the bug issue can arise. Your manual will mention this preventative maintenance and schedule.

Are you aware that these fridge units take several hours to get cold? Could it be that you just have not given it enough time? I usually turn ours on the day before we plan to use it,that way it is down to normal temp when we need it.

If the rig has been in storage for quite a while, and not properly charged, the batteries may be down below the point that the refrigerator will work properly. It takes a good 12 volt system to operate the controls and the sparking system for propane operation.

Just one more possibility as to why it will not light on propane.

Don't know about the newer ones, but I have a '73 Overlander which I replaced the fridge in and it didn't start up on propane either. I discovered that it has to have a 12V line to it to have it work properly, run thermostat . . . ignite. Just a thought.

Correct..12VDC must be present to run the fridge on LP gas. I found this out the hard way after spending some $200 to replace the control board (from Dinosaur Parts) onlt yo find the problem was a blown 20 amp fuse on the DC circuit.

Check the fuses!

I had a similar problem with not switching to Electric. After waiting 8 weeks for service appt. it turned out to be a fuse. BY THAT I mean an internal fuse inside the refrigerator. Not sure if propane system relies on a fuse but worth checking out. Fuses (2) were in small box inside the refer. Odd size fuses so now I carry replacement fuses for all items in the AS for the MANY inline fuses that exist. Such as refer, range hood, fantastic fans, water pump, trailer hitch lift and of course the ones I have yet to discover.

Silly, but obvious question...is your rig level?....LPG appliances like to be level to operate.

Have you tried to light it manually? Open the access door on the outside and remove the flue small access door,Have one person inside to switch to on and one person with a lighter on the out side when they signal you light it (or you hear clicking)If it lights it should stay lit until you shut off the fridge.If this works you need a new circuit board.If under warranty have them replace it and order a Dinosaur circuit board ($100) as they are much more reliable than the factory circuit board keep the factory board for a spare.
You might check the fuse on the refrigerator circuit board also when you have the access door open.

I have had a board go out while boondocking and lit mine manually and it ran until I got home 2 weeks later.

Can you hear the DSI sparking when you select gas? Most will keep sparking for up to 3 minutes.

As stated before id try to light manually with a BBQ lighter and also verify the gas is turned on at the back of the fridge. Usually there's a valve in the line.

This has happened twice to our fridge. After trying all the suggested fixes, both times we ended up taking it to the dealer to have a bad motherboard replaced ( under warranty). Evidently they are notoriously faulty.

Have to comment again to the newer trailers...our 1969 fridge requires no power at all to run on LPG. Lights every time, gets cold fast and can still make ice. Wondering what made them decide to make them so technical?
