We have a remotely opperated Hampton Bay fan, and I have changed the battery, but not the "code" yet. I have had no problem controlling it with the remote for the fan or the 2 lights, but lately it only stays on for like half a minute and shuts off. (both for the lights and the fan).
Is there something else wrong with the unit?
Will changing the codes solve the problem?

Try changing the "codes" first.
