Mine did that this week, it was fine two weeks ago. I went on top to remove the cover and spin the fan blade, but did not have a square drive screw driver.. So I took a stick, put it trough the vent hole and moved the fan blade just a little, went down, turned the thermostat and it worked fine. Just moving the fan blade gets it going.. Someone recommended a drop of Bar & Chain oil on the fan shaft, Thats on my "to do" list.
