The Solution: Upgrade the dimmer switch. Some dimmer switches are rated to handle 1000-1500 watts. This is usually the simplest solution. Secondly, you could try switching out the bulbs to LEDs or CFLs which us less energy than incandescent.
Can a dimmer switch cause a fire?
A circuit that continuously stays on can happen if the dimmer switches get overloaded by too much voltage. The fixtures attached to these switches might require a larger voltage than what the dimmers are designed to withstand. Dimmer switches can get extremely hot and possibly catch fire as well.
Can a buzzing light switch cause a fire?
This causes the crackling sound, and it can lead to burned contacts and heating of the switch and the wiring connected to it—all problems that have the potential for causing a fire.
Why would a dimmer switch buzz?
The voltage actually increases when you dim the light. A dimmer switch works by breaking up the AC current faster than our eyes can see, between the switch and the light. This creates an electromagnetic effect which can cause vibrations in the switch or the bulb. That effect is what you hear as a buzz or hum.
Are dimmer switches supposed to buzz?
One problem that’s often encountered with a dimmer switch is that it emits a hum or buzzing noise. It’s most commonly caused by a fault in the switch mechanism, or, more commonly, in the light filament.
How do I stop my LED dimmer from buzzing?
Here are some steps you can take to reduce or eliminate the annoying sound:
- Change Light Bulbs: If the sound is coming from the light fixture itself, you might try a different type of bulb. …
- Upgrade Dimmer Rating: If the sound is coming from the dimmer switch, you may be overloading the switch’s capacity.
