Just hook up the new switch exactly how you found it.

Hard to tell in the last picture how it was previously wired but what I'm seeing is top left with red and black are the switch legs for the light and fan respectively (are they the same appliance?) Top right/bottom right are just your 120v normal power just also using this JBox as an extra junction point. Is there an outlet below this switch?

Power comes in, power is also daisy chaining somewhere else. Also a double switch is there for co trolling 2 different things which is why there are 2 switch legs

To add on, if you're trying to control 2 things separately, then only your double switch will work. Black from the group of 3 blacks should go to the line side of BOTH switches. The lone black and red will go to thr switched side, one on each switch. Leave neutrals and grounds all tied together

So it looks like the switch previously just took power in and split it up for you onto the twi switches. The new one will do the same, so long as you don't break the little separater tab off the side, it's just that your new one will be external so you can see it.

All you need to do here is determine which wire is which. And even then, you really just need to know which one is hot/line in. So if you have any means of non-contact testing that, do that. Otherwise multimeter to check connectivity up to the fan by making a closed loop you can ID each wire. Absolute worst case you guess and wire it up. If you're wrong the switch simply won't have any impact or it will not turn on.

I didn't look at the new switch, but it 'may' require you to split the line in and wire to both terminals instead of spanning that for you.

That said, in the one picture there are black wires twisted together and no wire nut. Don't do that. Ever.

The neutral and ground are already "passed thru" this box to the fan. You could add a pigtail to the ground for the switch if you wanted. I always do out of an abundance of caution.

So in looking at the double switch, it would be one hot on the left, the single red wire from the fan on the top and the single black wire from the fan on the bottom? No ground connected?

If you looked at the pictures you could see why a layman is confused. The new switch isn't self contained with blue, red, white pigtails coming out of it. Why is the most unhelpful comment the most upvoted?

I've seen a couple of these switches before. Sometimes they have the line side already internally connected (or with a tab you can cut if you want them to be separate on the line side. I'd have to see a picture of the back side of it to tell you. But yeah you just need the one line side (with maybe a jumper if it is internally separated), and each switch leg connected to the other side of each switch.

If there is a ground stud on the switch (probably), ground it also.

Thanks for the reply! I think I may have got it. However, the fan is working, but the lights are not: https://imgur.com/a/WhKnUip

So right side the tab is still intact, so as long as that's power in, this wiring should work. However, if you're wrong on power and let's say the left black is power, this would make perfect sense- the red never sees power, which is likely your light then. Try swapping your blacks there.

One thing I forgot to mention with situations like this: since there's a red present and only one, you can bet that goes to the fan/light and is therefore not power. Which means the black that is part of that same run is ALSO not power. So by process of elimination, the other black is your power. It's also usually a good clue which one power is if there are a bunch of blacks together in a wirenut. No reason to have 4 runs to a single fan and the switch needs to interrupt power for it.

Sorry. Probably should have said all this earlier. Had just woken up from a nap and I have a young toddler so my brain is kinda fried at times

Thanks! So the one one the right is pigtailed to the hot in the wall, and the black and red are going up (I believe to the fan). Since that tab is there, they should be sharing the hot, right?

I also have a single switch, if that will work as well. The fan is remote controlled.

If the fan is remote controlled, you want to always have power to that portion, so no switch. Otherwise the remote only works if the switch is on.

I would verify which black the red is paired with and then you at least know which one runs to the fan and you're positive which one is hot.

Does the light work with BOTH switches on? You could be feeding power back thru the top one if, again, you have your blacks swapped

Should be, and it looks like you put the wire on the screw rather than into the back, so no reason they wouldn't be sharing the hot then.

Since it's a light: is the bulb dead? Is there something going on at the fan end that you need to look at? If you're positive you have the hot correct then what you have is what should work. If the light is still out, look elsewhere.

You mentioned elsewhere a remote for the fan, so really you don't want the fan off a switch, you want it always live so the remote works. (Assuming you plan to use the remote) in which case you would just wire the fan line directly to the hot and install a single switch between hot and the light.

The lights don’t work currently. The bottom one works, which turns the fan on and off. The top one does nothing, though I can verify that current is passing through with the voltage tester when switched on. Both the black wire and red wire on the right side seem to be going to the fan through the top left corner in the box. I can also verify that the black wire on the bottom right of the switch leads to the bundle of hot wires from the wall. Not sure what it was about the last switch that made the lights work…

Had a dummy moment. I used the remote to turn the lights on and they work! LOL

Time to open the fan/light and see if you can get continuity from the red line to where the lights are. I don't know of anything inside that switch that would have been doing anything at all besides simply being a switch.

Another option- red seems to be the light, right? Wire it directly to hot and see if you have a light. If not, your problem is elsewhere.

And I'm sure you've checked, but fans usually have a pull switch for the light. Make sure that hasn't been pulled, just in case. I know I've done that before

Yeeeeeeeah I just found the remote for the fan and turned the lights on. Everything seems to work now! Though, the lights still work without the red switch on, but it works so I don’t think I should mess with it any more than I have lol

That just means the black line runs everything at the fan. But if you want the switch to work, you'll just have to open up the fan and split the wires off from being tied together is all. The red wire is likely there from a previous install and simply capped off inside the fan currently.

Glad you got it working instead of having to call someone though. Congrats

Thank you for your assistance!
