I have a Hampton Bay ceiling fan Model AC527NN in a house that I am renting out. When I press any buttons on the remote, the red light comes on until I let go of the button, but neither the fan or the light will work. I tried a new battery in the remote, and still it won't work. I don't see any switch that I have to activate. I'm assuming that this has been working, but I haven't been able to get ahold of my former tenant to verify this.
