I have three harbor breeze fans with remote controls, located in 3 adjacent rooms. Somehow, all of the remotes are set to control all of the fans. Therefore, when the light is turned on in one room, it turns on in all three. It gets quite annoying! There is no pull string, but there is a switch to turn the power to the fan on and off. I am renting this home, so I don't know how they were installed. Any chance I could fix this problem? Thanks for your help.

You need to change the frequencies of the fans and remotes. Each fan/remote set should match, but not match other fans/remotes. See:
