Internal Wiring for Ceiling Fans
Electrical Question: How do I connect a new ceiling fan to the existing wiring and wall switch?
Sasanka in Texas asks:
- How do I connect a new ceiling fan that has 4 wires coming from the fan winding with the two wires of the capacitor, and of course make the connection with the supply phase and neutral?
- At the ceiling, how do I know which wire is for the running winding of the motor, and which wires are for the starting winding with the help of a Multimeter?
David in Oregon asks:
- I am trying to connect a ceiling fan/light. The ceiling fan has white and black wires, and I’ve got white, black, and red wires coming out of the ceiling.
- I connected the white and black wires, left the red alone and capped. turned on the light switch, and the fan would not come on. double checked, and everything was connected.
- I unscrewed the light switch, and it has red and black wires connected to it, with the white wore alone and capped.
- I went back up to the fan and connected the red wire in the ceiling to the white wire in the fan, thinking that the red wire was bringing power to that fan, but when I turned it on I ended up tripping all the hardwired fire alarms in my apartment. Now I’m not at all sure what to do.
Dave’s Reply:
Thanks for your electrical questions.
How to Wire a Ceiling Fan
Application: Wiring a Ceiling Fan.
Skill Level: Beginner to Intermediate – Best performed by a licensed electrician.
Tools Required: Basic Electricians Pouch Hand Tools, a non-aluminum ladder and Voltage Tester.
Estimated Time: Depends on personal level experience, ability to work with tools and access to the ceiling fan.
Precaution: Identify the ceiling fan circuit, turn it OFF and Tag it with a Note before working with the wiring.

The Main Wiring Connections of a Standard Ceiling Fan
For Sasanka in Texas:
- Ceiling Fan Wire to Electrical Circuit Wire Respectively, Described Below:
- NOTE: Wiring configurations may vary with ceiling fan and circuit wiring.
-
- Ceiling Fan Motor: Black wire connects to the circuit Black wire.
- Ceiling Fan Light: Blue wire connects to circuit Red wire (or as designated).
- Ceiling Fan Neutral: White wire connects to circuit White wire.
- Ceiling Fan Ground: Green wire connects to circuit Green or Bare Copper wire.
- Internal Components of a Ceiling Fans
- Motor Pull Chain Switch
- Light Fixture Pull Chain Switch
- Motor Capacitor
- Motor Rotation Switch
Replacing Internal Ceiling Fan Components
Ceiling Fan Component Wiring
- The exact make and model number number of the ceiling fan which you have would be very helpful.
- It should also be noted that most of the internal components of the ceiling fan rarely need to be disturbed or rewired unless an internal ceiling fan component needs to be replaced.
- If this should occur then the exact replacement must be obtained and then wired exactly as the original component unless otherwise instructed by the manufacturer of the part.
For David in Oregon:
- If the hardwired fire alarms are triggered when the wall switch is on then the lighting circuit is shared with the smoke detectors.
- In this case the ceiling wiring and the wall switch wiring will need to be tested and verified to identify the right wires that are used for the ceiling fan.
