Worst case scenario just replace the light kit and check your wiring but yeah obviously that wasn't OP's issue

Of course doing that with the fan still together/hanging is much more of a pain than just getting a new one, usually, especially if the fan is old. Most other electricians I know don't bother doing ceiling fan repairs, they'll swap em but any more than that's not worth their time. I'll do whatever but I'll be up front about it.

Especially since you're usually doing it for retired folks who can only afford so much...
