Ceiling Fan Wall Switch Wiring

I have a question regarding the wiring of the 2 wall switches. I have only 1 black hot wire to serve both the light switch and the 2 way switch for the fan. So I ran another black wire connecting the two switches hot connections. The light and the fan all work but there is a an annoying humming noise. I am curious if this has anything to do with it? I am not sure how else you could wire it.

The Fan is brand new and appears to work well.

Is this the same fan? http://www.doityourself.com/forum/el...ml#post2380055

We try to keep the same line going in one thread without starting new ones. Moderators may merge these threads, so heads up.

Is your 2 switches at the same box or different locations?

Try taking out the speed switch and just wire the single pole switch to the fan. Sometimes the rheostat in a dimmer or speed switch can cause humming noise.

I have tried both a speed control switch and a 2 way switch. Same result with the humming noise.

I also tried installing two separate fans, as I took the first fan back to the store because I thought it was a motor issue. But the second fan has the same problem. So I'm really confused on what the problem is. Its a relatively newly wired house.

I'm thinking it has to be with the wiring.

Are you able to take a picture of your switch wiring?

I have two leviton 2 ways switches.

The switch that controls the light has a red on the bottom, black on the top.
The switch that controls the fan has the black from the Fan on the bottom.
A wire connecting the switch that controls the light to the hot (top) of the fan hot switch on top.

There is only 1 black wire coming into this outlet box, That is why the two switches are sharing the same hot. I am not sure if that is normal.

JD,
I am fairly good at wiring and I have a dining room fan that hums. I don't know why I never replaced it. It looks nice and the hum is low. It sounds like your wiring is correct and you may want to go to a different brand of fan.

Thanks for the cool diagram. Wow.

I have the pink and black wires on the light switch (left switch in diagram) reversed on my switch.
The pink on the bottom and black on the top.

This is the only thread running on your fan problem as having two running at the same time in different forums causes a lot of confusion. There wasn't much additional information in the other thread so I didn't merge them.

Sorry i had a sloppy drawing. Lol Yeah, I read your post wrong, red on bottom of the switch but electrically it'll still work properly. If you wired your fan and switches as that drawing, the only problem I can think of is the fan itself unless you're not getting 120v.

Just curious. If I check the voltage. And I find out I am not getting 120V. How is that problem resolved to get more voltage?

This is the 2nd Fan I am having this issue with. as I took the first one back as I thought there was a problem with the motor. Turns out there was nothing wrong with either one of them.

Thanks for your help

By the way you were explaining the situation, I don't really think you have an issue with the 120v. But if you did, ouch, you'll have to check everything that's on that circuit. I don't recommend you working on live circuits.

Have you tried wiring it like thus yet (using just 1 switch)? Sorry sloppy drawing again.Name:  20150129_234622.jpg

If you can tell me the exact wire you see in the switch box and the fan box excluding the wires connecting to switches and wires from the fan, I can go into detail tomorrow morning.

The Switch Box has:

1 Back to Fan
1 Black Hot
1 Red

The Fan Box

1 Black
1 Red
1 White
1 Copper

I would like to keep it to two switches operating the fan and light switch.
I want to avoid having to pull chains as much as possible.
