    Wiring a fan with a red, black and white wire in junction box
    Yes, this is the situation. I bought a fan with the following wires: White, black, blue (down light) and gray (up light). I do not have a down light.

    The junction box comes with a red wire, black wire and white wire.

    There are two wall switches to control the light and to control the fan each separately.

    I have pulled out my electrical meter and when the switches are on, my meter lights up with red/white and black/white.

    I have tried putting the black and blue fan wires with the black junction wire and the white wire to the white wire and the gray fan wire to the red junction wire, but it does not work.

    I have tried putting black to black, white to white and the gray and blue fan wires with the red junction wire and it still won't work.

    My question? WHICH FAN WIRES GO WITH WHICH JUNCTION BOX WIRES! I am ready to pull my hair out. Is it possible that I need to put the black fan wire with the white junction wire and the white fan wire with the black junction wire? If so, where do the gray and blue fan wires go?

    Thanks for your help on this one, as I am completely and utterly lost, but don't want to be dead! :)

    Okay, let's think about this.

    Are you going to use two wall switches? Example - SW1 for the light and SW2 for the fan?

    Is the main supply line coming into the ceiling box?

    If all of the above is correct, then this is what you do. From the supply black, connect the White to the switches, Wrap the insulation with a small band of electrical tape to show that this conductor is a hot conductor.

    At the fixture, connect the black from the switch to the black for the fan. White from the fan connects to the White on the supply.

    Red from SW2 goes to Blue (for light) Cap off the gray conductor since you are not using it,

    If your wiring configuration of your wiring, please let me know.

    Yes, there are two switches on the wall, but I am not doing any wiring behind the wall.

    Out of the junction box attached to the switches there are three wires - red, black and white.

    The fan has blue, gray, black and white.

    I have already tried connecting the white to white, black to black and the red and blue from the fan to the red in the junction box. It didn't work.

    I have also tried blue/black from the fan to black in the junction box, gray from fan to red in junction box and white to white. That didn't work.

    I have found that when I test the junction wires that white and red and white and black will always create a strong circuit, but the light is barely on on my meter with any other combination. This makes me believe that white is my hot instead of neutral. Is that possible?

    Do you only have three leads (Black, Red and White plus a bare or green copper wire in the ceiling?

    If you only have three, then you would use black to the fan black) White to all whites and Red to blue and cap off the gray wire as it is unused.

    If there are two cables above in the junction box, one is the supply cable.

    It will a constantly hot Black when measured to the White in the same cable.

    The constant Hot black goes to the White (carries power to the switch). Please put a small black permanent marker on this conductor.

    Red will go to the blue fixture conductor, Black will go to the Black from the fixture and copper or green to the copper or green from the fixture.

    Question, the meter you are using, is it a Multi Meter? If it is then set the meter to 200 VAC, Put the black probe on the white supply wire. Put the Red lead from the meter on the Black/White (with stripe) you should see anywhere from 118 to 120 VAC. Then connect the red probe to the Blue/Red connection and you should see 120 VAS or there-abouts.

    Can you get an up-close picture of the fixture wiring for us?

    If you have voltage at the ceiling and the fixture does not work then there is something wrong with the fixture.

    Even if your white wire was hot instead of neutral (and it probably isn't) the lights would still light up. If you want to check it anyway put one lead of your tester on white and one on the ground wire. If it reads close to zero then it is neutral.

    I agree, the fan and light should work if both switches are on in both of the described wiring scenarios.

    Is it a remote fan?
