With everything working fine for years, our ceiling fan with light fixture stopped working. Power is on and, as far as I know, was never interrupted. I thought it might be the remote so I bought another Harbor Breeze remote and installed it. That didn't help. I wired the fan without the remote and it works just fine. SO neither the old remote, that's been working for years, nor the brand new remote work at all. I get nothing. Is their something else other than the remotes that could be bad?
