I have 6 remote control Hampton Bay ceiling fans, so far 3 receiver died. I spoke with Technical Support at King of Fans, they say it tends to go when the fan is about to or reach 2 years. I explained that its a manufacture defect and its to be replaced for free, since its expected to break...She said I should call Home Depot, I did, Home Depot said for me to call King of Fans, because King OF Fans make the fans for Home Depot. I have filed a complaint and is awaiting an answer..
You have to complain or there will always be a problem...
