Ceiling fan trouble wiring
 
I am new to this so please be patient. I am trying to wire a new ceiling fan. Out of the ceiling there are four cables, RED, WHITE, GREEN & YELLOW. From the fan there is BLUE, WHITE, GREEN & BLACK

how do I wire these? I have a 2 button switch one for the light and one for the fan.

Try this
Green to green
White to white
Black to yellow
Blue to red.

If the wrong switch controls the fan then try
Black to red
Blue to yellow

I do not know what the ceiling box wires are but the fan wires are as follows.
Blue = Light
White = Neutral
Green = Ground
Black = fan

If the two button switch is existing, this is how it's most likely connected.

Connect the white from the fan to the white in box.
Connect the green from the fan to the bare wire (ground) in the box.
Connect the black from the fan to the red in the box.
Connect the blue from the fan to the yellow in the box.

The yellow or red can be interchanged if the light comes on when the fan should come on.

Joed, you type faster than I can.....lol

To be sure about the ground : Check with an ohm meter which wire of the fan connects to its metallic parts. This one should be connected to the green from the ceiling

The other wires - try to connect them in one of the ways said above. Try to power it up. See what happens and correct if needed

First connect a lightbulb to red and white or yellow and white to assume which wire is from fan switch and which from light switch. I will call them fan live and light live




1. Fan works very slow and light is dim OR light is ok and fan off

if they both work when fan switch is on then swap light live and neutral

if they both work when light switch is on then move fan wires from light live to fan live / from ceiling neutral to light live / from fan live to ceiling neutral




2. Fan works very slow and light is dim OR fan is ok and light off

if they both work when light switch is on then swap fan live and neutral

if they both work when fan switch is on then move fan wires from fan live to light live / from ceiling neutral to fan live / from light live to ceiling neutral




3. Fan and light controlled by the wrong switches : swap light live and fan live

Ash, you got to realize this forum is mostly USA based users and "Live" is not a term used in the USA. It would help others greatly that you indicate your location, wire colors and functions differ greatly from the UK and the USA and giving someone the wrong info (which may be right in the UK) can be quite dangerous!

My answer is based on US NEC. 'Live' is equal to 'hot'

However, in USA, you dhouldn't need to test whether or not green is ground. because... green is ground :yes:

fungku, Never assume that the person who wired before you did it all according to code. A electricity for dummies book in one hand a and a pair of wire cutters in the other can be a dangerous thing. I've run across situations where circuits were wired with whatever was on hand (zip cord, 2 30A dryers wired off a single 12/3...). A couple of seconds can prevent an unpleasent surprise. pete
