    We just bought a used Aliner Classic 2016. I’m not getting gas flow to any of the appliances. I’m trying to resolve some battery issues too so maybe it’s best to keep the conversation around the gas cooktop as I don’t believe that should rely on any 12V service. I’ve got the gate valves at the end points open and the tank open but no flow. I looked online for commentary about the regulator and I’m thinking that’s the most likely issue. Since it’s pretty cheap to replace I think I’ll go that route to see if it fixes my problem - but wanted to see if anybody has anything to suggest before I go that route? Since the regulator is fairly new I don’t think it should have failed - but maybe some liquid propane got into it or maybe it was exposed to bad weather (or somebody adjusted the pressure and shut it down for some reason). Thanks for any suggestions.

    Could be the safety valve in the regulator. It closes when it senses a large gas flow. Close all gas valves in the camper for 5 minutes or so, to allow the safety valve to reset. Open the tank valve very slow to allow the camper line to pressurize slowly. Then try lighting your appliance. Make sure the vent on the regulator is turned down to keep water and dirt out.

    Does your camper have two tanks of propane? If it doesn't have an auto changeover valve, maybe the valve is pointing at the wrong tank.

    If you do have two tanks and both of them are open you can ignore this suggestion

    Make sure there is gas in the tanks. I have tried to trace a gas problem, and the guy was out of gas.

    Thanks - if anything its too full. I didn’t know how full it was when I bought it and I brought it to a UHAUL and they said it was completely full.

    Gate valves? There are no gate valves in the LPG system.

    I may be using the wrong terminology. I’m talking about the lever type of controls that are on the quick connect fitting on the inside and outside of the Aliner for the gas cooktop.

    I think my problem is the connector from the tank to the regulator or the regulator itself. Nothing else makes sense. I took the gas bottle and hooked it up to my outdoor grill and it worked fine. I have ordered a connecting hose and a new regulator and I’ll post when I replace the existing units to tell you if that solves the problem.

    Also check to see if the idiot before you teflon taped over the interior of the valve itself. Ive seen it happen.

    OK - finally updating. I changed out the regulator and the pigtail hose and the gas stuff is working with the exception of the furnace (Water heater, cooktop, and refrigerator work). The gas furnace doesn't even try to strike and I don't think the previous owners ever tried to start it. I haven't started to look at it yet but wondered if there is something pretty basic that I should start with? There's an analog thermostat and it does sound like there's a "click" of a contact closure when the temperature setting is set above the temperature in the camper. Thanks.

    I don't have one, but many post on Portal about furnaces. Last one I remember had a 4 amp in-line fuse going to a control board that was blown. Time to get the multi-meter out and make sure you have power to the unit controls and thermostat. May have to clean the burner and make sure the orifice is open.

    Definitely check the burner & orifice. Dirt/rust/gunk falls in there. Shop Vac it and the area around it.
    Also, make sure you're giving it enough time to get the air out of the lines. I'm sure you tried more than
    once, but something worth point out at least.

    By not even trying to strike , do you mean there is no clicking to start the flame? If so you dont have power going to the unit.
    See if there is a on off switch on the furnace or the thermostat or both. Not sure on you camper.

    There is an on/off switch but it's been "on" when I tried to start the furnace. I think it may be that there is a blown fuse - if the prior post is correct. I haven't checked voltage at the thermostat but no voltage to the control board makes sense given the symptoms. The Aliner is a 2016 and I doubt the furnace has been used (bought if from the second owner who I know did not use it).

    I'll open it and look but I expect that it's pretty clean. Don't think it's been used. Since I tried to strike it after testing the other appliances I know there is gas in the line (i.e. stuff downstream from the furnace was igniting.

    I'll check into the fuse - that seems the likely cause if there is a fuse on this unit.

    I would look real hard at the T-stat. Take your volt meter and check both wires at the stat

    Thanks. I'll do that. I don't have a wiring diagram but I'm assuming 12V in and out (out when the TSTAT asks for heat).
