We recently had a power outage that lasted for 3 days. When the power turned back on, our Concord ceiling fan started ringing. It is not working using either the remote or the pull chains. Any help would be greatly appreciated!

I would turn breaker off for at least 10 seconds.
If that doesn't work, bypass receiver if fan has pull chains.

That did the trick! Thank you!! I was told to turn off the main breaker next time our power goes out. Hopefully that'll prevent things like this from happening again.

Good Deal.

It is rare that a remote receiver can be "reset" but cutting power. Concord is a better fan than many, that might be part of the reason.

Be aware that cutting off power to a remote fan, and cutting it back on, can cause a power surge that can damage the receiver.

Glad you got it working.
