Light switch controlling multiple rooms


I recently moved into a home with electrical issues in 2 bedrooms. Both bedrooms have ceiling fans with lights. Bedroom #1 uses a remote in place of a switch to control the fan and light (all wires are capped). Bedroom #2 uses a normal switch.

The issue is that the power for bedroom #1 is controlled by the switch in bedroom #2. So the remote for #1 only works when the switch in #2 is on. #2 doesn't appear to have any issues otherwise. I need the power to each room to be separate. Any help would be appreciated!

Photos are coming in the next post...

Re: Light switch controlling multiple rooms


So, if I am understanding you correctly, the "switch in #1 is battery powered? As you said all the wires are capped. It looks like switch #2 might be switching the main live leg to your fan.

If you pigtail the blacks to the black wires all together on switch #2 this will allow fan #1 to work all the time. To get fan #1 to work via a switch I would leave one black wire coming from the pigtailed group and wire the red wire to the other side. You will then need to access the wires of the fan this switch controls and change its power wire to be the red wire. It looks like someone did a halfassed job of rewiring it at some point and mistakenly cut off live power by disconnecting the pigtail.

Re: Light switch controlling multiple rooms


Does the switch in #2 control the light in #2 properly? To make it not control #1 connect the two blacks from the switch together but then I don't see how it can control the light. You need to open the light in #2 and show us those connections.

Since the other box is jumpered from black to red I'm assuming the original wiring switched the red wire on the other box as well with the blacks all shorted together. You are correct that to know for sure we need to see the wires but I think its a safe bet that red goes to the fan.

Re: Light switch controlling multiple rooms


Since the red is only shown connected in one box is likely that the two reds not connected.
I suspect there is a three wire cable to the light box.

joed, thanks for posting the photos.
Yes, the switch in #2 controls the light in #2 properly.

Sdiver2489, yes the remote is bypassing the switch in #1.

Re: Light switch controlling multiple rooms


The power is being sent through the switch instead of being connected to the constant hot at the switch location. It is mis-wired.

Re: Light switch controlling multiple rooms


Here is the diagram I put together. I left out the white wires and ground wires for simplicity. https: //imgur. com/a/RLHLK16


I've tried different ways and only came out with 2 different outcomes

Outcome 1) I connected F and G together and connected E (red wire) to the switch. Both Fan #1 and Fan #2 continuously had power and I could not turn off #2 so the switch was not working.
Outcome 2) Connecting E to either G or F or keeping E disconnected. The result here was that switch #2 controls both Fan #1 and Fan #2, which is the same result as in the previously posted pictures

Re: Light switch controlling multiple rooms


Since switch has only two wires attached and controls both the light and the other room the problem has to be in the light.
We need to see the wiring in the light.

Re: Light switch controlling multiple rooms


Is there an attic above? It's possible switch 2 was wired to fan 2, and then later someone installed fan 1 and just fed it from fan 2 and blanked over an existing switch 1 which only controlled outlet(s).

Re: Light switch controlling multiple rooms


Power may be originating from fan #2. Switch power is then feeding fan #1 instead of the constant power at the fan box #2 feeding fan #1.


Or it can be like two offices where I work. Each office has only one light switch. both light switches control both offices (3 ways switching). Apparently it was one large office at one time and a wall was constructed to make two offices not separating the lighting.
