Got a ceiling fan with lights and the unit went dead. Have no owners manual.In the light unit there is a purple wire that is loose and I can't seem to find where to connect it. Also there is a black unit with 2 gray wires on one side and a red, a brown and that purple wire on the other side . There are 3 swithches inside that unit. What can I do? Thanks

Open this link, 2-3 threads down will be the contact info for Harbor, maybe you can get a manual. https://www.askmehelpdesk.com/electrical-lighting/ceiling-fan-troubleshooting-repair-frequently-asked-questions-46738.html#post359211

Are the lights dead too?

A manual won't help, a schematic might. But it might be an easy fix.
