| 1st check to see if propane is on and you have propane. 2nd make sure the fuses are all good. 3rd make sure that the LP detector is on and working. This should be somewhere by the floor, usually under the sofa or bench seat. If all that works make sure there is not any air in he lines. If you don't have a cook top run the hot water heater until it lights. Than try your heater again. |

Location: SE Louisiana | Check to see if you have hot water.... If you have enough to heat water, you should have enough for the furnace to operate. |

| Your thermostat is for a Coleman Mach air conditioner with a heat strip on it ....
it may or may not have ever had a heat strip ... this is usually for the AC unit only ... are you sure there is not another thermostat somewhere?? LQ's have no standardization like RV's do ... so the genius that wired your LQ may be the only one that knows what he did ... lol ..
NOT KNOWING if you have an electronic sparker or not ... your pilot light may be out which does not let the furnace fire off ...
Your furnace number is a Suburban Furnace which means it is a propane furnace!! If you would give a $100 right now for it to work ... take it in to a RV place to get fixed. Propane furnaces are too dangerous to mess around with ...
Check and make sure your battery is good since the boards for the furnace run thru your batteries 12v system. If bad batteries .... use a standard ac car garage charger to charge them up full charge before putting on your trailer ... ...also open the inside door on your furnace and reset all the breakers to make sure one has not thrown itself ...
Check and make sure you do not have dirt dabbers or other air obstruction in the furnace intake on the side of your trailer ... usually a round wire mesh. There is a sail switch on the furnace that must move to operating stage for furnace to run if it has enough air coming in the intake ..
Igniter sparker is also run by your 12v system to turn pilot light on and then increase flame to heat up the thermostat tip and then turns the burner on .... spider webs, dust, or no propane in the small pilot light tubing can be the problem .... do not mess with the sparker other than blow it with low pressure air ... to spark it has to be a certain calibrated distance etc etc .. .....
Apparently you are normally plugged into land current without a generator ...... without plugging in trailer to AC of course A/C will not work ... if you have 2 fully charged batteries .. .. propane furnace may work for a max of 15 minutes since blowers will suck the power out of the batteries in a hurry. .. Winter time temperatures are the best time to work on a furnace problem ... If you only have one small 20# propane tank .. you might consider installing a second one with an automatic switch over at the tanks ... you have to watch it and refill the empty one when needed and to manually open tanks to use and to shut them down for extended periods of time ...
CHEAP BACKUP FIX ....>>>>
Make sure your propane sensor inside is working and you know the mild rotten moldy type of smell of propane ........ and then do this for a backup or permanent source of heat ... it is the least expensive ...... go to Walmart and buy you a couple of $25 Lasko heaters ... they are about 8 inches tall ... use only one if it gives enough warmth so you do not overload your ac breakers ... and use minimum electrical items when using these heaters ...
When at home unplugged or traveling long distances ... you have what is called ghost electric users ... main things that have a remote controller are ghost users ... unplug these items or flip their breakers off at your box inside the LQ....
Even combined with the other posters valid suggestions ... as you can see the furnace is a notorious trouble maker with a lot of crazy things that could keep it from working ... lol.... |

Location: 100 miles from Nowhere, AR | Batteries are good, and I was running the generator. As far as I can tell, the furnace is on the roof with the AC and there is a dual vent on the side of the trailer down low--one hole drains water from the AC and the other is the furnace vent. I have 2 big propane bottles, much bigger than 20s, no auto switchover. I'll check to see if I have gas or air in lines this morning and if that doesn't give me a clue, I'll take it in. Gotta have heat! |

| If your LP detector has gone off, it shuts down the propane. We had to reset our LP detector, it went off due to low battery, then the heater started working again. |

I think I saw the green light on, but will double check. Thanks. |

I think you have us all confused now .... a propane furnace will not be on the roof .... so you probably have a heat strip out on your Coleman Air Conditioner .... OR the strip has it's own breaker which may be soft thrown ... so go thru your breaker box with LQ plugged in .... and turn each breaker on and off ... they should be firm when you throw them to ON status ..
The Suburban number you gave is for a propane furnace should be at floor level in your LQ ... your propane use may be limited to your hot water tank and if you have a cook stove .... ???
GOOD LUCK TO YOU ... AND LET US KNOW WHAT THE PROBLEM TURNS OUT TO BE ... |

I don't know where the **** furnace is. LOL The model number was written on a cabinet door by whoever in MO installed the LQ. I was just guessing. I've never had a trailer with more than a heat strip. I didn't even know the stupid thing ran on propane until I looked it up.  |

The furnace usually isn't visible. Mine is under my refrigerator and then have a few ducts in the trailer. Look for the duct openings close to the floor. One of them is usually with the furnace. I've honestly never looked at my furnace. I just use it as needed. I bet you don't have a heat strip and just a furnace. |

Location: Mi | Mine did this in the middle of winter also and I was at a 3 day barrel race. I thought my propane had ran out, switched tanks, nope. Ended up getting a new thermostat and it has worked great ever since.

My thermostat went out on me too a few years ago. OP can you turn on the AC? If that doesn't work either your thermostat might have gone bad. Mine is digital with a few more options than yours. We ordered one and hubby installed it. |

Location: MO | If all fails go buy a $20 electric heater. Plug it in and get warm. We always carry a small one just incase. Works great . Warms fast and we even have to turn it way down.  |
