Turn the fan on. Note direction the fan is turning and which way the air is blowing.
Turn the fan off. Allow the fan blades to come to a complete stop.
Locate the fan reversal button on the fan's remote control. The button may simply indicate "reverse" or there may be multiple buttons to indicate which way the fan will turn. "Summer-mode" should be used in warmer months, since the counterclockwise movement of the fan blows cool air down to the living space. "Winter-mode" should be used in cooler months, since the clockwise movement of the fan pulls cooler air up toward the ceiling, away from the room.
Press the appropriate remote control button to turn the fan on in the desired direction. Confirm the fan is now turning in the opposite direction than it was originally.
Turn off the fan. Allow the blades to come to a complete stop.
Set up a stepladder under the fan. Climb up to the fan. Flip the directional switch on the fan motor. This switch is often unlabeled and sits just below the fan blades.
Descend the ladder and move away from the fan blades. Turn the fan on. Ensure the fan is now turning in the desired direction.
