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.

old biscuit gave the best answer but here is something else to check check the converter because if it is not charging the batteries the furnace will just blow cold air because even tho you are on shore power the furnace still uses the batteries to operate so my guess is either your batteries are going bad or the converter is not charging really well
