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
