We are sorry to hear that the fan motor has a hum. The fan is designed to be whisper quiet and an audible humming noise is unacceptable. There is a 24 hour break in period for most ceiling fans, including this one, in which the noise may clear up. If not, it is possible the humming is coming from a loose screw vibrating as the fan is running and can be easily remedied by tightening with a screw driver. If that does not resolve your issue, please contact customer service at 1-855-HD-HAMPTON. Noise issues are fully covered by the manufacturer warranty.
