Go to Lowe's and they have replacements. It's not fun, but replacing the receiver isn't bad if you follow the directions. The odds are that the driver chips for the fan and lights have burned out in the receiver so it doesn't matter what you tell it to do, it just can't do it anymore. More than likely a power surge took it out, but sometimes they just quit. Just take in the model number and pick up the right replacement and follow the directions in the package. An hour or so later you should be working again.
