Have a 52" Harbor Breeze Pacific Grove outdoor ceiling fan that is installed under a porch roof. The fan hand light have worked fine. The other night the lights starting to dim and brighten on their own. The remote failed to correct the issue. The fan speeds and on and off work with the remote fine. New battery installed in remote and still have the issue with the lights dimming and brighten by themselves. Only the pul chain can turn them off. Any ideas for a fix?
