How to install a ceiling fan fight dimmer switch and compare with other way of joining

Installing a ceiling fan or dimmer can be a daunting task. Without the proper knowledge and tools, installing a ceiling fan or dimmer can be hazardous to the operator. Installing a ceiling fan, wiring a dimmer, or replacing can be dangerous if you don’t know what you’re doing. With that in mind, Toby Nwazor with the website created this guide to help guide you through the process of ceiling fan fight dimmer switch installation and dimmer wiring, along with photos and videos. In addition, we compare two ways to connect ceiling fan fight.

Introduction of ceiling fan fight

The structure of a ceiling fan consists of the following main parts.

Electric motor

Two main types are capacitor type and short circuit type, with the main parts of motor design including 2 types: stator and Roto. This is also the most important part of the details that make up the ceiling fan because it directly affects the quality of the fan such as (rotation speed, wind speed, equipment operation).


This is the main part to create cool wind. In the past, propellers were usually made of iron with three main ways arranged at an angle of 120 degrees to the upper cutting board of the Roto. Today, however, by modern technological improvements,


The material and number of blades become more diverse for users to choose from 3-blade, 4-blade or including 5-blade ceiling fans,…. 

Gearbox device of ceiling fan

This is the part used to adjust the fan speed according to the wishes and needs of the user.

Steps to install a ceiling fan switch

Steps to install a ceiling fan switch

Before installing the switch, you need to install the ceiling fan first, the instructions below will help you do the best.

Step 1

First, fix the mount on the ceiling. The screws used for mounting the mount should be based on the material of the ceiling. Choose screws that can secure the mount and must withstand the pull of the fan to be installed.

Step 2

When installing the ceiling fan, it should be noted that the power cord of the motor is led from the inner hole of the rod, then insert one end of the rod with two holes into the lifting end of the motor, install the connection bolt and lock it to securely, tighten the fixing screws.

Step 3

Lift the ceiling fan to the hanger. Note that there is a groove on the hanger and this groove should hook into the convex point of the hanger. Then connect the power cord, and the wiring needs to be based on the requirements of each different ceiling fan. (Generally, the white wire of the three wires is the E wire, the black wire is the N wire of the motor, and the blue wire is the L wire of the ceiling fan.) After connecting the cable, lock the wave cup to the mount.

Step 4

Align the 3 small holes on the propeller with the 3 small holes of the propeller wire. It is recommended to tighten all the fan blades in a uniform order to prevent the blades from being angled and causing the ceiling fan to rotate when vibrated.

Step 5

Fix the corresponding assembled lamp ceiling fan blades to the motor and tighten the fixing screws. Then, gently rotate the motor by hand to check if the motor is flexible when rotating, and confirm that the propeller does not collide with any objects.

Step 6

Connect the assembled power cord of the lamp holder to the remaining power cord in the motor switch box, then connect the lamp holder to the switch box and tighten it with screws. Then remove the lamp holder, install the lamp cap, lock the lamp cover with the lamp holder, install the source and tighten it.

After the installation is complete, you should check that all the screws on the ceiling fan are tightened, then turn on the power to check if the ceiling fan is working properly. If the ceiling fan has a pull cord switch, one zipper controls the on and off, the other pulls the switch and the fan speed. The zipper can be extended, but we don’t recommend it to our customers because too long a zipper can bounce behind the propeller and get entangled in the rotor when spinning, creating a hazard.

What is a dimmer switch?

Dimmer switch ceiling fan is a very compact, modular electrical device that allows installers to disassemble with the effect of changing the rotation speed of the ceiling fan. The ceiling fan potentiometer consists of an alloy main coil with high power resistance and is wound around by a conductive post attached to a C or hand crank. On the surface of the fan dimmer switch, there is a design with a vortex knob or another type that is a lever type. This tool is connected to the sweep bar from which it creates two resistors that are changed according to the position of the sweep bar, which can be understood as the increase or decrease in fan rotation speed.

Working principle of dimmers

The operating principle of the ceiling fan potentiometer is almost the same as the gearbox of the ceiling fan. However, with the following outstanding advantages, ceiling fans using dimmer switch are becoming more and more popular and used:

  • The design is more convenient, compact, and luxurious for the house than the gearbox.
  • Using it for a long time continuously also does not worry about getting stuck or slipping.
  • Installation and replacement are very simple and quick.
  • Adjusting the rotation speed of the ceiling fan is “stepless” quite different from the gearbox that has to adjust the order and turns of rotation speed in turn.

Tips on how to replace the safety switch

  • When installing ceiling fans and wiring, you must have an experienced electrician or qualified personnel operate them according to various standard procedures.
  • During ceiling fan  installation or wiring, check whether the local voltage is suitable for the ceiling fan, must turn off the switch and do not work with the mains.
  • You must read the instructions and various safety documents in detail before installing a new ceiling fan and check the attached assembly instructions.
  • When punching or drilling holes in the wall, do not damage the electrical wires and negative water pipes inside the wall.
  • At the installation location you have chosen, when the propeller rotates, do not touch any obstructions and leave no obstructions from the edge of the propeller.
  • The screws for fixing the ceiling fan must be able to withstand a pull of 16 kilograms to ensure the safety and stability of the ceiling fan during operation.
  • When you install a ceiling fan, level the blades or wipe them clean, without changing the curvature of the blades.
  • Do not install the ceiling fan control switch near the bathtub or where the shower is accessible.
  • Please do not arbitrarily install any solid-state circuits or accelerometers and other devices in this ceiling fan system.
  • The installation of ceiling fan is an overhead operation, you must pay attention to safety. Be sure to tighten all screws and coils during installation.
