I have a aire flo 80000 BTU 95% put in in 2010, we have 84.5 inches of snow, woke up at 8:30 am cold, cleared away 3 feet of snow from vents, worked until 3:30, cleared vents again, still not working. I took off the tubing hose and drained out all the water even took a dryer brush to clean vent out side, blower clicks on, runs for 30 seconds and shuts off

Which blower? Is it the small one on the front of the furnace or the one which circulates air in the house? Any error codes?
