The answer to 'dimmer switch replacement schedule' is that dimmer switches typically last 10-15 years with normal use. However, the exact lifespan can vary depending on factors like the quality of the switch, how often it's used, and environmental conditions. As dimmers wear out over time, they may start flickering, buzzing, or not dimming properly.
It's generally recommended to replace dimmer switches every 10-15 years as a preventative measure, or sooner if you notice any issues with their performance. This helps ensure your lighting system continues to function reliably and safely. If you're unsure about the condition of your dimmer switch, it's best to have an electrician inspect it.
