The preexisting fan became lopsided so upon removal, the wasn't a proper ceiling brace. So replaced the brace. Problem arose on rewiring as the fan/light works but the bedroom switch and the across the the hallway bedroom switch both don't work. I assume they're related. The ceiling has two sets of cables.

First cable has two copper ground wire, a hot white wire, a neutral white wire, a hot black wire, a neutral black wire. (6)

Second cable has a copper ground wire, a neutral black wire, a neutral white wire. (3)

The fan has a black, blue, and a white wire.

It is a single two-way switch. The fan has two chains.

The fan works when I connect the fan's black/blue with the hot black wire and fan's white with hot white. But doesn't connect the switch.

I have no experience in electrician things. Got a free multimeter to test hot or not and google.

 

No such cable exists. A cable wouldn't have two bare grounds. It might have a white and gray but not two whites. It might have black and red but not two blacks. I'd ask if conduit but you seem to be saying bare ground and conduit usually doesn't have a bare ground wire.Not a correctly connected cable if true.No such switch. Do you mean a single pole single throw "light switch".

Please post pictures of the wires both at the fan and switch. http://www.doityourself.com/forum/li...rt-images.html

You need as fan rated brace and a fan rated box. Is that what you installed?

 

Sorry, I guess I mess up on the terms and caused confusion.

The 3 wires
The "6" wires. I don't know. Only one black/white pair shows numbers on the multimeter, everything else is zero.

The switch.


And yes, I tried installing a metal brace/box kit.

If it helps, the original instalation had 2 pointy-ish red caps with wings, 2 marker-like red caps, and one tiny yellow cap. I think.

 

First minor issues. Best practice you should not have used a back stab connection at the switch. They can be unreliable. You need cable connectors in the fan box. The cables can't just go through the hole.

You obviously have a switch loop. That means at the ceiling at least two 2-conductor cables. One 2-conductor cable is the switch loop and the other is power in 2-conductor cable. Based on the number of individual cables there is also a third 2-conductor cable that is power out to another fixture or device.

Using a multimeter you need to find which cable is power in. Measure between the black and white of each cable to find which cable reads ~120 volts. (A non contact tester won't work.

With breaker off and the multimeter set to ohm scale have someone flip the switch on and off. Check black and white of each cable the cable that is fluctuating between open and continuity is the cable to the switch. The remaining cable is to another device. In the diagram below it is the cable labeled Load 1.

 

Well, all of this was installed by the original owners. There are only two cables that leads into the hole from the attic. Like, ----E. They are frayed out after they enter the hole as you can see in the pics. The cable on the left that looks like it has six wires, has power. The right does not. The fan has a blue, black, and white wire. I get the idea of a switch loop but I don't know what to do with it. You'd have to explain it to me like a child.

 

There are TWO cables coming into the left hand knockout for a total of three cables.

They may be taped together but I can see them both in your picture.

 

There are obviously three cables. You would never have two grounds or two whites in a cable. Which cable shows 120 volts? Is it "A"?


Best guess from not so clear picture.

P.S. Didn't you notice the three cables when you replaced the box? If not remove the box to verify.

You need to add NM-b connectors at each hole. Something like this: https://www.munroelectric.com/silver...ctors.(Plastic)
