Ceiling – Why would ceiling fan reverse air flow without me changing directions

ceiling-fancoolingfan

I have this exact ceiling fan, and so far it has worked nicely. It is mounted in my bedroom, I believe height to floor is about 12 feet and the rod from the ceiling to the actual fan is about 18 inches (estimates here, if you want more specifics I could go and measure).

But for all of summer it was blowing fine – pretty powerfully, but largely hot. Now that the climate has changed and the breeze is cooler, I literally feel absolutely NO AIR below it. When I hold my hand beside it, I can feel breeze up there – almost as if it is sucking air from the bottom and pushing it to the top.

I haven't tested this theory fully yet, by say taping a piece of paper to the roof and seeing how it responds when the fan is turned on, but a lot of this is anecdotal just based on what me and my wife feel.

Is there any reason that the air flow would reverse, without any explicit reason. I was looking for a switch or something on the fan, and I can't find one – so I don't think someone could have flipped it while it was being cleaned, or is there some hidden mechanism that I am unaware of?

Help!

Most ceiling fans have a reverse switch. In the summer, you want cool air blowing down in the center to give you the breeze. In the winter, you want the warm air from the ceiling to mix with the rest of the room, but without the breeze, so you reverse it and the warm air descends around the sides of the room where you're less likely to feel the draft.

If yours is reversed, then I'd suggest looking a little harder for the switch. It's often on the fan itself when they have the pull chain. However, with yours, I'm going to guess it's on a separate controller. If it's not a dedicated button, you might have to hold a button for a few seconds or some other trick (this is why I never throw out manuals).
