Furnace starts out great & then later not?
Two trips in a row now are furnace starts out great! Lots of heat & by morning when we wake it blowing cold. Can anyone help me fix this? Suppose to another cold night.

If related to battery operation then most likely a low voltage sail switch issue.
If not, could be an oil trap in the copper line to the furnace IF it works when warm (lower viscosity) BUT not when cold (higher viscosity). This type of issue is probably more common with using propane bottles then with frame mounted propane tanks..
