Rewiring a switch controlled receptacle to a ceiling fan


Hello,

I am trying to rewire our bedroom so that a switch that currently turns on/off a receptacle will instead control a ceiling fan and leave the receptacle always hot.

Receptacle: Has 3 cables coming into the box. The outlet has a 1 hot wire and 2 neutrals attached to it. In the box there are 2 hot and 1 neutral wire nutted together.

Switch: Has a 2 conductor cable coming into the box.

I have installed the fan in the ceiling and have run a cable in the attic from the fan to the switch box. At this point I am confused as to complete the wiring of the switch and the receptacle. Any help would be greatly appreciated. Thanks.

Disconnect the switch wire to the receptacle(and at the receptacle).
Wire the receptacle directly.
Run a new 14-2 wire from the ceiling to the switch on the wall.

How do I know which wires in the receptacle are coming from the switch?

Take wires off the switch and wire nut or tape them together or make sure they are making contact with each other. Go to receptacle location with a meter set to Ohms and see which pair of wires has continuity.

You do not have 2 hots spliced to a neutral. That is part of a switch loop. That white is a hot to feed power to the switch. The black from the same cable as the white is the switched hot back to the receptacle.

Will the ceiling fan have a light kit?

If the switch is off, the receptacle will be off. There's probably only 3 wires attached to this. One will be the neutral (Silver screw, which will stay on the receptacle)and the other will be the ground and the last one will be the switch leg(on the brass screw).

The receptacle has 1 black, 2 white, and a ground attached to it.

The black wire(on the receptacle) will have a white wire paired with it coming into the box. The white wire associated with it should be the other switch leg. It will probably be connected to a black wire(constant power) under a wire nut. The white wire sends power to the switch and the black wire sends it back.
You should put a tester on this pairing to confirm it's live, whether the switch is on or off.
The black wire that's connected to the white switch wire(under the wire nut) can be put on the receptacle and the other black wire ,on there now, can be removed. Test to see if the outlet is live. This should make the receptacle permanently on. The switch leg can then be capped in both boxes.
This scenario is if the switch leg was wired properly. The black wire(power leg) is supposed to be interrupted in the connection. Sometimes you see the white neutral leg interrupted. If that's the case, the rewiring scenario will need to be changed.

It is pointless to abandon a perfectly good cable going to the switch when the OP wants the switch to now control the ceiling fan. With some simple changes it can be re purposed . A new cable from the switch to the fan would then be run.

Yes that was my post regarding another room in our house. The difference in this room is the 3rd cable going to the receptacle instead of 2 like in the diagram.

The switch leg goes to an outlet on the wall. You could run the wire from the ceiling to the wall outlet, but the box might not have the capacity to take another wire.

The switch loop goes between the switch and the receptacle already.

He wants to have the switch loop go to a ceiling fan. That is far away from the wall receptacle.
