Ceiling Fan and Switch Wiring Problems
I have a ceiling fan with a light that was controlled by a 2 switch outlet.
- It was able to separate the light and the fan on dimming and fan speed.
- When I installed the new fan, black to black, white to white and blue to black or white, no functions come on.
- This led me to unhook the switch and check connections.
- The switch had previously been replaced with some difficulty from a standard 2 switch with no dimming.
- Once I did this, the outlets in the room no longer worked, the fan and the light didn’t either.
- I disconnected the switch completely and got the power to the outlets back.
- My Switch has a black wire (hot) a Red (Fan Neutral) and yellow (light neutral).
- I have 1 hot black wire in the switch (house) and a house neutral.
- I have an outlet black and white and a fan black and white, but can’t get them to work right with the switch.
- Un-switched, I managed to get the fan and light to work, so it’s not a bad fan (my original thought as to the problem.
Any clues as to what I can do next?

How to Identify Ceiling Fan and Light Switch Wiring
Application: Ceiling Fan Electrical Wiring.
Skill Level: Intermediate to Advanced – Best performed by a Licensed Electrical Contractor.
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 switched outlet wiring and the proposed location for the ceiling fan.
Precaution: Identify the switched outlet circuit, turn it OFF and Tag it with a Note before working with the wiring.
Notice: Installing additional electrical wiring for a ceiling fan should be done according to local and national electrical codes with a permit and be inspected.
Ceiling Fan and Light Switch Wiring Configuration
- Identify the Power Source, typically a black for power, white for neutral, and a ground.
- We know that we need the power, and that the power is looped down to a switch using another cable.
- For conventional switching the “Neutral” is not used in the switching process, however “the white wire” is often used and should be identified with black tape or marker.
- Neutrals are shared for the ceiling fan motor and the ceiling fan light.
- All of the ground wires are bonded together and connected to switches and the ceiling fan.
The switching becomes clear when you focus on where the power enters and the route it takes to accomplish the switching.
