In one room there is a Hampton Bay ceiling fan which has a remote control. A few weeks ago the whole device stopped working, meaning we can't get either the fan or the light to turn on. We replaced the battery in the remote control, and checked the switchbox to make sure the circuit wasn't tripped. Any ideas?

Does the LED on the remote still light?
