I have 2 (black, red)wires on my fan. what is yellow wire for?
466456
On three pin connectors for fans, the red wire is 12V, the black wire is ground and the yellow wire is a speed sensor output.
466457
The yellow wire is the tachometer signal. Most motherboards use that signal to know at which speed is the fan running.

Generally the first 2 wires in a 3 wire fan plug are the DC hot and ground, the 3rd wire is used to read the rpm of the fan by most newer mother boards. If you are replacing the unit in a PC that has some sort of temp control that varies the fan speed it will take care of the speed control automatically. Otherwise it should be full power all the time in systems without fan speed control.

Hi, this product is not the correct product for you. However, at your own risk, and the fan nor the wiring diagram not in front of me to check it. It is really hard to know what each wire is. Typically, the Red and white usually connect to the power, blue to the light (dimming is done usually through the remote receiver) at this point there is usually 1 more wire for the motor. You have 3 left that is because your fan reverses via the remote. You can buy the correct one that reverses on amazon or ebay or try to Google the wiring diagram. I wouldn't touch it unless I knew what was what. You can burn out the unit very easily or make a fire hazard or get hurt. Hi, this product is not the correct product for you.

Yes - if your fan is not working and everything else is - then it is probably the switch - which is a part that can easily break. I tired to fix the old switch but that is impossible. Just be sure to mark where each of the four wires go to make sure you get them back in the proper place - otherwise you will be guessing through trial and error. Good luck

You must look at the capacitor. Remove the cover plate on the bottom and look at the little rectangular device with 3 or four wires. Be sure the fan is off ! Then try to match it to the ones available on the net. The values are rated in "uf" so you can compare them. Write down the colors of the wires and the connections, a close replacement will work. Hope this helps !

On mine the green wire is in the middle, and then I have two red wires one solid red and the other with a yellow stripe that go on the sides. Thats all I can tell you, hope it helps

Black is 0 V (ground or negative), the next to it, yellow, is the + 12 V (positive). Next green = sensor of rotation speed, then blue is the additional, programmable 0-12 V (PWM). 2nd and 4th are sometimes interchangable, but not always. Just sticking a second wire from the system board to the 4th fan's won't activate some of the fans. But putting a PWM into the second wire of a fan is more likely to control it. At fans it's better to look at the position in the connector, rather than colors. 0 V is always the first, edgemost, corresponding to the plastic tooth. The 3rd (sensor) is at the opposite tooth, and the 4th PWM is the pin protruding beyond the plastic tooths to the side. Looking like an additional contact "added later" to the fan standard. And in all computer wire sets, i guess, a black wire is the 0 V, and if there's no black, then a white should exist, and the white is 0 V.

probably ! my fan had only 3 or 4 wires and i figured it out. I am not so mechanically inclined, but I was willing to try to fix my fan. It had only 1 speed ! this did the trick !

You can wire the fan either way. It just depends on what you have for the electrical connection now. The connecting wire is not included with the fan. I used the one that was already installed with my old fan. It has a normal 3 prong plug. Since the plug and wire don't move once the fan is installed, the old wire was like new.

You need a separate switch. Fan has a small junction box with knockouts for wiring connection.

You need to connect only the red & yellow wires across the switch. Red wire comes from the battery and yellow wire goes back to the relay coil. The black (ground) wire can be ignored.

the shunt is internal and low-side, you want to connect the ground of your load to the yellow wire then ground the whole unit with the black, than connect the red to the voltage you want to measure

if you remove the lighting fixture, or cover if your fan does not have a light. You will see the capacitor there. Just color match the wires and Connect.

For me there was one already installed to control a fan. The existing one went bad and locked into full power so I replaced it. There was three wires from my fireplace. One is power that is looped with a thermostat and the other is a neutral. Should be simple swap out, resolder the wires and it's ready to go.

I would connect it to "Y" thermostat wire which is normally yellow; this wire calls for the condenser (outside machine) to come on when thermostat calls for cool (cool and heat on heat pump condensers).

You can also join the 2 wires on the left if you have only 1 wire to connect to. Some fans have only 4 leads rather than 5.
