My Hampton Bay ceiling fan will run fine but the light flickers, how can I repair this?

I have a Hampton ceiling fan and the fan parts works great but the light flickers, how can I fix this?

Flickering light in a ceiling fan would most likely be a poor connection of the light hot (usually blue or black with white wire) and the hot (black) in the ceiling box.
However could be anything. If you are using CFL bulbs and have a dimmer switch, dimming could cause flickering.
