I have a Hampton Bay Ceiling Fan, Devereaux style, with a remote to turn light and fan on and off. The fan does not start, but the light works. I have replaced the batteries a couple of times, but it's still the same. The owner's manual says to have the transmitter and receiver frequencies to be the same on both in order to make it work, but it was working all along, and suddenly stopped. I know the transmitter is the hand held remote control but I don't know where the receiver is located. The manual does not tell where it is located. Help!

Does the light still function with the remote as it should? Does the fan have pullchains?
