How do I reverse the blades on a Hampton Bay remote controlled fan. There is nothing on remote to indicate reversing blades. IT is on a rod from a very high 18 foot ceiling. It has up and dow lighting. Remote has numbers of JUO7078T on it.

Check the fan body for a switch of some kind.

Are there pullchains on the fan body?

Did you buy the fan yourself, or is there a possibility it is a replacement remote?
