We recently did some remodeling in the house to include some electrical and since then, our downstairs remote-control Hampton Bay ceiling fans no longer work. They worked yesterday (one day after the electrician left) and now only "click". What is going on and how do we fix this problem?

Do the lights work? What do you mean they "click"? What happens when you try to activate the remotes?
