We recently remodeled our home and had 3 Harbor Breeze ceiling fans installed. Being that we did not install the fans ourselves, we do not have the instruction manual. All of our fans are set to the same transmitter frequencies, so that when you turn one fan or light on, all of them go on. I found the switches in the remote control to change the frequency, but cannot find the switches in the fan itself. I did find a peculiar black box inside the fan, which I guess is the receiver, but there are no switches on it. Does anyone have any idea how to switch the receiving frequency of Harbor Breeze fans?

They would have to be on the black boxes somewhere. Does it open up?
