Question by gh4874: Home Heat and air blowing cold air on heating setting plenty of propane.?
Answer by Brother Darrell
On standard propane furn. if the fan is coming on & blowing cold air only, the fan/stat is probably the problem. Most of the time an unplug the electricity to the furn. for 20 min or so will reset it. Then it might go for a while (days/weeks/years) before acting up again. I usually replace them with a normal fan/limit assy. to perminately fix the issue. Hard to do on Christmas day. By the way: have a Merry Christmas.
