So the short answer here is you need to go back to the store. We checked the Harbor Breeze Bradbury ceiling fan manual, and it does not list the part number for the light kit that comes with the fan. So, we’re limited in terms of what we can do to help. Even if we could locate the light kit, you’d have to pay for it – we’re a third party website, not the manufacturer – so this is a retailer issue.
Try not to miss your 30 day grace at the store because it’s unlikely warranty support will help with that.
We recommend you return to the store within the 30 day grace period. Good luck!
