How to Install and Connect a Capacitor in a Ceiling Fan?
If you ever face a problem with the ceiling fan such as humming noise, slow speed, not running the fan or fan light kit is working but the fan has been stopped even with proper power supply, then you are the right forum as one of the most common reason is a bad or blown capacitor instead of faulty internal windings, power supply failure or jam bearings. You may check and test the capacitor by 6 methods if it is faulty or in good condition.
Simply to the point, there is a single phase (split phase induction) motor in ceiling fan where we need a starting capacitor to split the phase angle between starting and running windings to produce a magnetic field. A capacitor just do it as it provides leading phase shift by 90° (as some current flow through the staring winding). This way, voltage across staring and running windings have different phase which provide rotating magnetic filed leading to the rotation of motor rotor.
As mentioned above and shown in fig below, there are two winding in a ceiling fan motor which is known as Main Winding (Running) and Auxiliary (Starting) Winding. We need to connect the capacitor to the starting winding (auxiliary) in series. The neutral should be connected to the neutral. Don’t forget to connect the earth wire to the proper grounding and earthing.
Note: The wiring colors in this tutorials are for illustration and clarification only i.e. These colors used in this guide are only for guidance and do not necessarily represent regional variance. See the bottom notes for US and EU Wiring color codes (NEC and IEC). In addition, some manufactures may use different wire colors, this way follow the regional color coding or check the user manual guide for clear explanation. If still not sure, contact a licensed electrician for proper installation.

For proper installation, you may contact the licensed electrical. Read carefully the safety precaution at the end of this guide.
Now, If we got a faulty capacitor, we may change it by three different ways as follow.
Replacing a faulty capacitor in a ceiling fan.
Wiring a Starting capacitor with Ceiling fan.
Connecting a 3-in-1 capacitor with ceiling fan, reverse switch and pull chain string.

Replacing a Faulty Capacitor in a Ceiling Fan
Suppose a simple fan without light kit need to be replaced with a new working capacitor having the same rating, follow the instruction below:
First off all, switch off the main circuit breaker in the home distribution board to disconnect the power supply.
Now, remove the faulty capacitor by cutting the exact wires connected to the faulty capacitor.
Replace a new capacitor by connecting the Red (live) wire (from ceiling fan) to the first terminal of capacitor and connecting the blue wire to the second terminal of capacitor.
Connect the red and blue wire and put a wire nut and electric tap and insert it in the wire connector as shown in fig below.
Connect the black (neutral) from the ceiling fan to the second slot of wire connector.
Now connect the live and neutral to the power supply. Switch ON the main circuit breaker to test the ceiling fan.
Good to Know: Don’t connect the capacitor on Neutral Wire i.e. only connect the capacitor the red and black (or blue and black which depends on the manufacturer and user manual), otherwise, instead of anti clock wise direction, the fan will start to rotate in reverse direction i.e. backward direction (clockwise).
Wiring a Starting Capacitor in a Ceiling Fan
If you got a problem with ceiling fan starting capacitor, follow the step below to install and connect a new capacitor.
Disconnect the main power supply be switching off the circuit breaker in DB.
Remove the blown/bad capacitor from the fan by cutting their related wires.
Connect the red wire to the first terminal of new capacitor and the second terminal should be joint with blue wire with wire nut (don't forget to use electric tap as well) and connect to the first slot of the wire connector as shown in fig .
Now connect the red (live) from wire connector to the fan speed control regulator or fan dimmer switch and SPST (single pole single through or single way switch) in series.
Connect the great wire and neutral from the fan to the earth and neutral wires from the main distribution board.
Switch on the main breaker to check the fan it it working properly as expected.
Wiring a 3-in-1 Ceiling Fan Capacitor with Reverse Switch & Pull Chain
This method is little bit complex due to different wires in 3-in-1 capacitor and one must follow the wiring color codes used in the wiring (NEC and IEC wiring color codes are given below). To replace and change a three-in-one capacitor with a ceiling fan with builtin light kit and reverse switch, follow the instructions below.
First of all, switch of the main breaker in the household DB to cut off the main power supply.
Connect the green/yellow ground wire to the household grounding system
Now, remove the previously installed capacitor in the ceiling fan by cutting red and gray wires.
Do the same for pull chain switch i.e. disconnect the (grey, brown, purple and black) wires from capacitor to the pull chain switch and ceiling fan reverse switch.
Now connect a new 3-in-1 capacitor by connecting the gray wire to the slot 1 in the pull chain switch, the second gray from capacitor to the middle terminal of reverse switch.
Connect the brown and purple wire to the slot 2 and slot 3 respectively in pull chain switch.
Connect the orange and pink wires from the fan to the reverse switch slot 1 and 3 as shown in fig.
Connect the white wire as neutral from the main board to the fan, middle slot of reverse switch and light kit.
Connect the black wire as live (phase or line) to the L slot of pull chain switch. An additional joint through wire nut to the blue wire from the fan to the builtin light kit as shown in fig.
Now switch on the main distribution board to check the ceiling fan through reverse switch (which is used to change the fan direction of rotation), pull chain switch for different speeds and ON/OFF control.
General Safety Precautions
Electricity is our enemy, if you give it a chance to kill you, remember, they will never miss it. Please read all caution and instructions while doing this tutorial in practical.
Disconnect the power source before servicing, repairing or installing electrical equipment.
Use the proper cable in size with this simple calculation method ( How to determine the suitable size of cable for Electrical Wiring Installation)
Never try to work on proper electricity without guidance and care.
Work with electricity only in the presence of those people who have good knowledge and practical work and experience who know how to deal with electricity.
Read all the instructions and cautions and follow them strictly.
Doing your own electrical work is dangerous as well as illegal in some areas. Contact the licensed electrician or the power supply company before practicing any change in electrical wiring connection.
The author will not be liable for any losses, injuries, or damages from the display or use of this information or if you try any circuit in wrong format. So please! Be careful because it’s all about electricity and electricity is too dangerous.
In the above ceiling fan capacitor replacing tutorial, we showed three methods to change and replace a faulty ceiling fan capacitor and will add more wiring tutorials in the future. If you know a specific method to do so, let us know in the comment box below.
