I purchased three of the same ceiling fans three years ago, Model #640-657 the fan part still works on all three, one of them still has light, however, the lights on the other two worked for a few days and never worked again. I was told by an electrician that both fans had a bad Ballast. Does anyone know where I can find this item.

Thanks in advance.

Are they fluorescent lights? Regular lights do not have a ballast and I have never seen a fluorescent in a house fan.
