Problem with the furnace

I bought a 2012 Flagstaff V-light in September 2013. I have never needed to use the heat. It's going to get down into the 20s Thursday night. When I went to test out the furnace it ran for 30 seconds or less and then shut off, but the thermostat was still calling for heat. I have to turn off the thermostat and then turn it back on to heat for the furnace to come back on, but the same thing happens. I know there is propane because I tested the stove and it works fine. If any of you experts out there can give me any advice it would greatly be appreciated. Thank you

Hi Getastro My V Light 30wikss Just arrived this week still need to walk through. How many times did you try to reset the furnace? It may take several tries to clear any trapped air in the gas line if It has never been used before. When the furnace is tiring to light can you hear the spark igniter snapping tiring to light the pilot. If not then the you my have problem with the electronic ignition board or a spider net was built over the pilot and igniter shorting it out and not allowing the furnace to start. Another possibility is that mud wasp have built a nest in the furnace exhaust not allowing the proper air flow to start the ignition process. Hope this helps Tim

The heater fan runs first to make sure there is no collected propane in the heater. This is probably what you are hearing. After the fan runs then the gas valve opens and the igniter tries to light the flame. If it does not light the furnace stops.

More than likely the propane has not reached the furnace yet. Try lighting the stove to clear air form the propane lines and and try the heater again. It may take several tries before it lights

Update

So today I took the furnace out and started to check things out. I started with the limit switch and then moved on to the sail switch. Both things checked out fine. My next plan to do a bench test on the entire furnace. I know propane is working fine in the trailer because the oven the refrigerator work gas.

Our furnace was having the same problem, a insect built a nest on the igniter, we had it cleaned and is working properly now. Don't forget to put a scream over the area that does help.

I had this happen to me once at a Nascar event. Camping world had a booth with a service person on site. My problem ended being the mother board. cost me $125 for part and install at the event.

Furnace problems

Gestastro,
I have a 2013 Rockwood and while on assignment to North Dakota late fall and early winter. My Airexcell furnace would not stay lit. I had three, service calls and finally replaced the circuit board. The old one had almost melted. Luckily, the mfg replaced the entire furnace under warranty. Circuit boards can cause a fire in campers. Hope this helps.
Sean

On Tuesday we picked up our 2015 Micro Lite 21 FBRS. We just went to a local campground to try it out for the night. The trailer was winterized so we didn't use anything that called for water because we didn't want to have to winterize it all over again after just one night. We live in the south so our temps are typically pretty warm, but not last night. We dropped down to 20 degrees and we ran the heater all night long. That is until it went off about 8:00 a.m. We tried several things to no avail and called the dealership where we purchased it the day before. They walked us through the same things that we had already tried and then told us to bring it in because it's still under warranty, being only ONE day old! So, in the frigid cold (single digits with wind chill) we hitched it up and drove over 50 miles to the dealership. They removed the furnace and said that we "had some loose connections." They tightened this and that and we were good to go. Makes me wonder what else may be loose and stop working down the road??????
