We can't see it.....

You need to be our eyes and tell us what's there.....how its done.....who done it....and what the VOM reads......just about the time you tell us everything YOU have the "Eureka" moment and find the problem

Huh?....."when i looked at the wiring all the wires coming from the fan are green"

"when the breaker was off the wire connected the the neutral wire from the breaker still had a spark"......then you probably have multiple circuits inter-connected......or ?

One of the best troubleshooting approach is to "Divide and Test".....

Disconnect one fan and see if it works......remove the Rheo and try On/Off

"......measure Once.....cut Twice....

throw that one away and cut a new one...."

well first off i didn't do any volt readings which i know should have been my first rule of thumb. i was short on time when i looked at this and really just tried checking the obvious like disconnected wires, crossed wires etc. etc. i only pulled apart 1 fan, but both fans are identical. i just recently installed another fan and all the wires were color coded and from what i have rread of other fans they are all basically coded the same. blue, black, and white, but there was only green wires coming from the fan, i will try and get some pictures tomorrow and post up here. i did disconnect the rheostat and was unsuccessful. both the rheostat and the wall switch are boxed in with just 2 black wires coming from them. i could not find the brand name of this fan the only thing i got was the model cs-5201 and model number 0001231 i have tried googling them numbers and the only thing i get is places trying to sell fans. when i go back to work on this i was planning on just starting at the breaker box and start following wires. my biggest question was, what would make the fan only hum when turned on? both fans have the same problem. i didn't know if maybe someone knew right off the top. both rooms and a bathroom are ran off the same breaker. i know having the fan instructions would be a big help too. my friend says the person that had the house before her installed them and she has lived in the house for about 6 years.

Of course you need some voltage readings....

When you removed the rheostat did you connect the black wires to each other ? we need to get the power to the fan......

Is there a single rheo for both fans ?

Did the fans work correctly for the last 6 years ?

according to my friend these fans have never worked correctly. when i hooked the single pole switch up without the rheostat i hooked 1 black to the red and 1 to the white thinking i needed the ground to complete the circuit. i did check the voltage from the breaker and it gets the 123 volts i was negligent in checking the voltage at the fan tho which will be the first thing i do when i go back. i knew to do that was just complacent on my part. i was thinking this would be an easy n quick fix which doesn't seem to be the case. in the junction box there is 2 white wires with the black tape (not hooked to the fan) which i know means its a hot wire. the person that had the house before had done a lot of rewiring and i'm not sure exactly how he ran the wires which will be something i look at next time too.

ok i got some readings i only took them off of 1 fan tho i was short on time. i disconnected the wall switch and took my readings there. they had installed 12/3 wiring and the readings went as such. the black and white i got 120v the red and white i got 32v the red and black i got 73v. when i did the reading at the fan i didn't get anything, but i'm assuming thats cuz the wires at the wall was disconnected. when i turned off the breaker to the room there was still power to the wall switch, but no power to the lights on the fan. this was before i disconnected the wall switch to get the readings. i hooked up a regular single pole switch to the wall and got nothing.

see all the wires are green and these are the wall switches 1 single pole and the rheostat

Since the image quality sux......lets start:

You are using a digital VOM.....the "odd" voltages do not exist....they are phantom voltages....with ELECTRICAL work you are better served with an analog meter or neon tester or a lightbulb in a socket!

You have Two rooms/Two fans each with lights you have 4 switches....CORRECT?...... You can't connect two fans to one controller (unless it's something/special)

Switches Make-Break the HOT wire(s).....never the Neutral....

The "all the wires are green" comment....

LOOK at the wires that are connected.....someone has (illegally) used a piece of GREEN to make up ALL the pigtails in the box.....the actual connected wires are unable to be seen in the poor quality photos but they sure aren't green.......

So as an example in each room at the wall switches:

The Power White connects to the Fan White (via the 12-3 white)

The Power Black gets connected to each "switch"....

The Rheostat/switch gets connected to the Fan Black(via the 12-3 Black)...

The Dimmer/switch connects to the Light Blue(via the 12-3 Red)......

yes i realize the images wasn't very good and i did think after i got home that they may have ran green wires thru the shaft for whatever reason. i'm usually short on time when i go over to my friends house due to the variation in schedules and my main goal today was getting the readings. i have a fluke digital meter. my biggest question is with the 12/3 why i get the different readings? when i test the red and black should there be a reading between the 2 beings how they are both power wires? i'm thinking my next step might be just to take the fans down and plug into a pigtail and try to figure out the wiring unless the bottom half of the fan is color coded. my other question would be on the single pole and the rheostat they both just have the 2 black wires coming out of them. yes there is 2 fans in 2 rooms and they both have seperate controls and both have the same problem. in the first room when you turn on the light switch there is a hum at the switch. i am thinking that would be a neautral somewhere, but i also am fairly inexperienced and this is all a learning venture for me. i do appreciate your patience, i will be trying to get back over there tomorrow to do more investigating.

Now you're starting to scare me....""this is all a learning venture for me"".....DIY requires a basic understanding AND ownership

If you don't own it....you can't fix-it

""my biggest question is with the 12/3 why i get the different readings? when i test the red and black should there be a reading between the 2 beings how they are both power wires?""

It's Phantom Voltage because you're using that **** digital VOM.....The correct reading is 0 volts

http://en.wikipedia.org/wiki/Phantom_voltage

""my other question would be on the single pole and the rheostat they both just have the 2 black wires coming out of them.""

How many more wire do you need?????

The switch MAKES the BREAKS the circuit....In/Out......Line/Load....Black and Black

throw that one away and cut a new one...."

don't be scared i am a certified electrician i just finished school and am now getting my associates degree i just don't have much experience in the field. it is starting to make sense to me now tho. the 2 wires coming from the light switch just seemed kind of weird to me, but your right it just breaks contact and only needs 2 wires. i am going to try to get back over there today and pull the shaft apart and see if its all green wires coming from the fan motor or if someone added a pigtail. i am still curious tho as to what all could cause the hum from the wall switch in the other room.

I have a lighted ceiling fan with a wall switch. I pulled the chain to turn the lights on and when I did, it was like a light bulb blew, I lost power in half of my living room, a kitchen light and my rangehood and also to my outside light(switch is on same one for fan) I don't know what happened. Could you please help me in possibly repairing this and restoring my power without it costing me $500.00 ? Maybe if you could tell me where to start to look in the fan for a clue as to what happened or something.... Thank You
