I have a small bedroom ceiling fan and it has two pull chains. One to turn off and on the light and the other to control the fan. The one for the fan is no longer working. It does not catch to turn the ceiling fan on. Can this part be replaced and repaired by a self doer or do I need to buy a whole new ceiling fan ?
