I recently did a full home remodel as a result of a major insurance loss. we decided to upgrade and had the contractor install 4 LED recessed lights in the bedrooms where there was previously only one flush mount ceiling light.
I now want to add a ceiling fan (without light kit) in the place where the old ceiling light was. I was happy to find that the box is rated for a ceiling fan. However, I'm having trouble understanding the wiring and how I would connect the new fan, using the switch on the wall to control (the rocker switch currently controls nothing). The green ground runs through the knockout into the conduit and it feels connected when I tug on it. Maybe the electrician used the wires in this box to install the recessed lights?
How would I wire in a ceiling fan in this setup?
