wiring a ceiling fan with light with dimmer switch switch

The modified waves are “cut off” halfway through each cycle, so it should only deliver 50% of the power that the full sine wave. In the image below, the topportion represents a typical 120V sine wave, while the bottom two portions are modified waves produced by a dimmer. You can think of it like an electrical grid black out that happens 120 times a second.īecause of this, you'll need to replace your wall dimmer switch with an on-off switch. If you were to provide a modified sine wave to a device that is designed for straight 120V, it could behave abnormally or just stop working.

Most electrical devices, including our controls, are designed to operate at full voltage (e.g. The More Complicated Answer (We ARE engineers after all): Replace the wall dimmer switch with an on-off switch. The brown wire from the fan should be connected to the single way switch and fan speed dimmer switch while the black wire should be connected to the separate single way switch for light control. Fan speed would need to be controlled by a pull chain or in some newer fans a wireless remote. This setup allows you to dim the light in the fixture and also switch the fan off and on from a separate switch.

The wall dimmer switch reduces power flow and interferes with the fan control. Ceiling Fan Wiring Diagram (Light Dimmer) This ceiling fan wiring configuration is quite common in bedrooms.
