Hello out there. Has anyone come across this issue. I don't leave both propane tanks open, only one at a time. This is my way of knowing that one of my tanks is empty. We bought our 2016 313rlts new. I have used this procedure in all of our trailers. One tank would run out of propane, I would go out and switch tanks manually. A bit chilly in the middle of the night but I always know that one of my tanks is full. I don't like the auto switch over because I have no idea when the regulator switched to the other tank.
Anyway back to the issue. I manually switch over the tank to a known full tank, cycle the thermistat and it used to start again. Now it will not start until I pull the 15 amp fuse and reinstall then the furnace works properly. Obviously, I am reseting something but not sure what????? I reviewed the atwood manual. It doesn't have any discussion about running out of propane if I need to do something special . Some guidence would be appreciated.
