2015 jayflight issues

[hartfam007]

I desperately need some advice, feedback, help from you guys. I have two recent issues with my 2015 Jayco Jayflight.

#1-my furnace fan comes on sometimes this summer for no reason at all. It did it when the furnace was off so we took the thermostat off and it still does it once in a while. Not often but once in a while.

#2 - our propane warning goes off like once every two or three weeks, we blow it out and re-set and it's fine for several weeks then it happens again.

*during the summer months we have electric hook up and dissconnect the battery.

Any help is greatly appreciated.
Thanks

First and foremost you should never disconnect the battery while using the trailer ! The converter constantly tries to charge the battery if the battery disconnected or dead it can and will eventually overwork the converter and ruin it . The battery acts as a buffer for all of your 12v components (ie , lights,furnace,propane detector..) The converter was never designed to supply 12v to everything without a battery installed . I would reconnect the battery and see if the issue still occurs .
