One of the most common causes for premature dimmer failure is over-lamping. Dimmer switches are designed to handle a specified maximum load in watts. Quite often, when a single dimmer switch is used to control a number of light fixtures, this maximum wattage is exceeded.Secondly, do dimmer switches wear out? The most common mode of dimmer failure is when the dimmer can still turn the lights on and off, but can no longer dim. Dimmers have sensitive electronics in them. High current (even a momentary short circuit) almost always fries them. Likewise, people ask, how do you turn off Lutron lights? This little pull-out tab is located on the bottom of the light switch right below the off button. Place your fingernail underneath, and you’ll find a little notch that lets you pull the switch out. This turns the lights off, but it also cuts power to the light switch and light fixture entirely.Can dimmer switches be adjusted?The dimming range of dimmable CFLs and LEDs can vary from bulb to bulb and from manufacturer to manufacturer. Setting the adjustment dial so that no light output is visible or output is unstable (excessive flickering or flashing) may damage or degrade the bulb. 1. Turn dimmer on and move slider down to the bottom.
