A faulty dimmer switch can cause buzzing in LED lights due to the way it regulates the voltage. LED lights require a consistent and stable current flow to function correctly, but a dimmer switch works by reducing the amount of electricity that reaches the light bulb. This reduction in electricity causes the LED light to flicker and buzz, which can be particularly noticeable if the dimmer switch is not functioning correctly. The buzzing sound occurs because the LED light is not receiving enough power to function correctly, and the electricity is not flowing smoothly through the circuit. Therefore, it’s essential to ensure that the dimmer switch is compatible with LED lights and functioning correctly to avoid any buzzing sound.
If you’re experiencing buzzing or flickering in your LED lights, it may be time to replace the dimmer switch. To start, turn off the power to the circuit by switching off the breaker in your electrical panel. Next, remove the dimmer switch cover plate and unscrew the mounting screws that hold the switch in place.
