When we first got our 36FL the weather was cooler so used the furnace to heat the trailer overnight. I only run off one tank of propane at a time then switch over to the full one when the fist one runs out. The first time I did this it worked fine. I closed the valve on the empty tank, switch the regulator so the arrow was pointing to the full tank, then slowly opened the valve on the full tank and everything worked as expected. Early this morning the second tank went empty so when I went out to repeat the process for switching tanks but this time I couldn't get the furnace to light. I turn the range top burner on to purge the gas line but there was no fuel coming out.
I worked the regulator valve back and forth a few times hoping it was a stuck diaphragm or something but still nothing. The I swapped out the empty tank with the full one and that seemed to do the trick but still didn't solve the problem.
When I was outside looking things over I could smell gas so I checked out the full tank and the connections but all was fine. I went to the other side and discovered gas flowing out of the gas line. I didn't connect the empty tank to that side because I was going to get it filled.
I have used this method for several years on our old trailer and never had gas flow out of the unattached line.
Do you think I have a bad regulator or is there a problem with my method. The owners manual says to switch the valve to the full tank, which I did, but it doesn't say what to do should that not work than that.

This problem you discribed could be a couple of things first the regulater could have froze this is not uncommen when a high consumption device such as the furnace has been running for a period of time especially in cold weather what happens is the moisture in the propane will freeze in the confined spaces of the regulator. To solve this problem pay attention to where you filled the bottles, propane from the south tends to have more moisture and oils in it. (I don't know why). If the regulator freezes up try to warm it up with out using heat source that could cause a fire (don't use a torch or hair dryer or anything like these).
The other problem could be a bad regulator, if you get gas coming from the other line with no tank connected it very well could be a bad regulator. Hope this helps.

Sounds like a bad regulator you should be able to select either tank any time.the hose should not leak at all have it checked also.
still working

I closed the valve on both tanks, released the pressure and worked the regulator handle back and forth a few times. I then turned the regulator toward one of the tanks and slowly opened that tank. Everything seems to be working fine now. I don't know if what I did had anything to do with addressing the problem but all is well.
Thanks for taking time to read and opine on my post. Helping each other when we can will help build this forum.
