Was using the furnace tonite but noticed the fan kept running but the air from the vents were cool. Swapped tanks but didnt make a difference. Got propane at the cook stove. What should i look for?...
Were you trying to run the heat to make sure it worked even though it was warm inside?
In other words, was the fan set to "lo" or "hi" so the fan ran non-stop but the heat did not ignite because it was set at 72 but it was much warmer in the camper.
