I have an older home with a Hunter fan that stopped working. I took down the fan and noted that there were 5 sets of wires coming into the metal overhead box. Found hot black wire feed from main breaker and traced out 3 other sets that fed various outlets, overhead light in next room, etc. Final wire set went to the wall switch. This fed straight down to the wall switch. No other wires at the switch. Worked fine until found loose wires were the cause of the fan not working but now confused how to rewire this back up after pulling wires apart and cleaning them up. Fan has 1 white wire, a black & a black/white wires & 1 green wire. Black & black/white wires connected. Note: a white wire was found in the middle of 4 black wires when I took it all apart.

I am assuming that the black/ white wire of the fan is to the light of the fan/light. I am assuming that you want the switch to control the light and the pull chain to control the fan itself..
Connect the black wire going to the switch to the black/white wire of the fan/light. This is the wire that returns power from the switch. Connect the white wire going to the switch (that was the one you found connected to the blacks) and all of the black wires together along with the black to the fan. These are you hot wires. You now have power to the fan, the switch and all other outlets. Connect the white of the fan/light and all white wires together. These are you neutrals. Put some black tape on the white wire going to the switch. Next time you will know that it is a hot wire going to the switch.

How was the fan controlled, does it have a light?

There should be at least two wires going to the switch.
