Verify that the power is off using a voltage tester.
Wear safety glasses and gloves as protection against electrical shock and debris.

Tools and Materials

Step-by-Step Instructions

1. Remove the Faceplate

Use a screwdriver to remove the screws holding the faceplate in place. Carefully pull the faceplate away from the wall.

2. Disconnect the Wires

Identify the wires connected to the dimmer switch: typically black (hot), white (neutral), and red or blue (dimmer connection). Loosen the terminal screws and disconnect the wires.

3. Remove the Old Dimmer

Unscrew the mounting screws holding the old dimmer in place. Carefully pull the dimmer out of the electrical box.

4. Prepare the New Dimmer

Strip about 1/2 inch of insulation from the ends of the wires.

5. Connect the Wires

Connect the wires to the terminals on the new dimmer switch: black to brass (hot), white to silver (neutral), and red/blue to the designated dimmer terminal.

6. Secure the New Dimmer

Push the dimmer into the electrical box and tighten the mounting screws.

7. Attach the Faceplate

Align the faceplate with the dimmer and secure it with the screws.

8. Restore Power

Turn the power back on at the breaker panel. Test the dimmer to ensure it is working properly.

Tips

If you are not comfortable working with electricity, consult a qualified electrician.
If the new dimmer doesn’t work, check the connections and ensure that the dimmer is compatible with the wiring and load.
Dimmers are not designed for all types of lighting. Check the manufacturer’s specifications before installing a dimmer on a particular fixture.

Conclusion
