    Hi,I would check to see if you have a flame. No flame COLD AIR.Some thing in controls will hot ignite your pilot light.your blower should not operate till it senses the heat of flame.Also your ignitor tip may be bad,may look red hot ,but not enough to ignite gas.Be safe, call furnace repairman.Good Luck.

    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.
