LP gas flow
A few days ago the temp hit 26 degrees around 4am and remained at that temp until around 8am. The furnace was running fine at 4am; however, about 8am noticed that the heat coming out of the vents was not very warm. Checked the LP gauge and the red indicator was showing...did not think the tank could be empty since I had just flipped that tank on the day before. Also, it was plain from the moisture buildup on the tank that it was more than 3/4 full. I turned the tank off, disconnected it, and removed it and shook it (the latter was done just to confirm there was gas in the tank). When I put the tank back in and connected it, all was well again. Do these tanks freeze???
