Why LED lights buzz with no dimmer? Your LED lights should not buzz without a dimmer. For some reason those have been known to buzz without a dimmer.

What does it mean if my dimmer switch gets hot? This is a huge red flag for me if your dimmer switch is hot. Warm is ok but hot is not. You have too much current running through the switch that cannot handle the load. Check the total watt capacity of your dimmer switch. Then, add the total watts for the lights that are connected to the dimmer.

If you have too many total watts combined with your lights, then swap out the bulbs to ones with lower watt usage or upgrade your dimmer switch to one that can handle more.

My recessed ceiling LEDs, which are on a Lutron dimmer, buzz not when dimmed but when on, loudest at full brightness and getting quieter as dimmed! Is this unusual? Phil, that has happened before. You really need to get a dimmer that is compatible with the LED bulbs.

A dimmer works by reducing some of the voltage from the line so that the amount of energy going to the bulb decreases. This ends up dimming the output of the light bulb. When you add and remove voltage, you will end up cooling and exciting the filament. When you do this, you end up with vibrations. These vibrations can lead to buzzing sounds. This means that the vibrations will be reduced and the buzzing sound will go away.

There are two main problems associated with fluorescent light bulbs — buzzing and flickering. If your fluorescent bulb is buzzing, that probably means that it needs to be replaced. This is because you likely have an old ballast. Do take note that all bulbs are susceptible to the humming problem due to being in the same circuit of another appliance. Since it only hums when you turn on your respective appliance, you can probably just ignore it. The last possible cause is simply a defective bulb.

However, bulbs that are constantly humming probably have some sort of defect in them. The only way to address this is to simply buy a new bulb.

This usually happens to an old or worn-out bulb. In that case, it is a possible sign that the bulb may bust anytime soon. However, it is important to know how the noises started in the first place so that we know how to fix them. Try all of the fixes we mentioned above in chronological order. The last resort is to change the defective bulb or change your entire circuit system.
