Furnace Problem. Please help!

[Filly12]

Hi everyone, i have 2011 sunset trail 29qb and took my RV hunting over the weekend with the family. The furnace was working properly but then I noticed a problem. The furnace would start, heat would come out, then shut off within 30 even with the thermostat at the highest temperature. Then, the furnace would start again and do the same thing. This happened all night and It got cold in the RV.



Any help would be appreciated.

I don't really know where to start with the issue, but it seems like some kind of fault detecting circuit is finding a fault and shutting it down, or else the temp sensor in the thermostat is sitting RIGHT beside a vent?

I would say that it will need to be brought in to a dealer to be checked. Gas flow scares me personally.

I remember when we used the furnace for first time this past February on our trip south to Florida, furnace would be cycling on & off quite a bit. On the ST25RB they placed the furnace floor vent right under and about a foot away from the thermostat. I ended up removing floor register & covering 1/2 of vent blowing towards thermostat with cardboard, (then putting register back) thus forcing air towards the other side away from thermostat. Works absolutely fine now. This may be your issue as well. Good luck. Edited by: Tonemeister

I am sure you have checked the exhaust site for your furnace? If plugged or partly obstructed it is telling the furance it is overheated and it shuts down...just a thought

Anybody with a Sunset Trail Reserve you might want to have a look at this topic http://www.crossroadsrv.com/forum/fo...ID=51356#51356 as there are a few other issues with our type of trailer coming up.
