We have had five Hampton Bay ceiling fans in our home for about 6 years, and have never had any them do anything out of the ordinary. But for the past couple of days the lights have been turning on and off by themselves, even while the remote is in clear view and nothing is touching it. And they don't all turn on at the same time, or off. But it is annoying to have the light turn on in my bedroom in the middle of the night, and very disconcerting to walk past a closed door and see a light coming from under it--and walk by moments later and it is off. Very spooky.
What could be causing this? What can we do about it?
