Thank you www. Lol sounds like a bees stuck in your switch. It could be because a transformer problem you need to tel me what it is connected to. Also could be the light switch most of the time it's the light switch. Hope this helped. Most dimmer switches buzz some worse than others it's usually normal and not a problem it's the transformer inside what causes this.
There can be a few reasons. Recover password. Remembered your password? Back to login. Already have an account? Login here. I have eight watt lamps connected to a single dimmer switch.
It makes a loud buzzing sound when the lights are dimmed. How can I fix this problem? From time to time, we hear from folks who have noticed a buzzing sound coming from either their light bulbs or a newly installed light dimmer.
They notice that something is not quite right because the buzzing was not occurring before the switch was installed. Is this normal and, if so, what can be done to minimize it?. Sometimes when a triac-based dimmer controls a light, it can produce an audible hum from the light bulb or the dimmer itself.
Many dimmer switches use triacs which are electrical semiconductors, like transistors, to control the flow of electricity through the dimmer. Like water flowing through a garden hose, sometimes less flow is desired so you turn the water valve to the desired output. To dim a light, the dimmer circuitry tells the triac to lessen the flow of electricity through the triac. The dimmer will reduce the flow of electricity by removing parts of the AC voltage when dimming is engaged.
Many inexpensive or lower quality dimmers will not properly reduce this flow, and a resulting buzzing sound can be heard. When bulbs are at full brightness, the triac turns on most of the AC wave cycle.
At this point, there is not much loss of voltage, so the bulb doesn't buzz. When a lamp is dimmed, the triac effectively switches the lamp on and off times per second. If the filament in the bulb is not rigidly mounted, the magnetic field induced by the rapid rise in current can cause it to vibrate - resulting in an audible buzz.
This extra safety step is worth doing because there was an unlikely fault with your circuit board due to the off-chance. You should then unscrew the wire connector from every set of wires that are positioned on the switch. As with all aspects of this job, make sure to be careful when removing the dimmer switch to avoid causing damage to the wiring. Lastly, you should fit the new dimmer. Hook the new dimmer switch by fixing it to the old wires, ensuring that colours match the wires.
Loose wiring is a common reason why faulty dimmer switches arise, and there can be safety risks too. Sometimes the issue can be resolved by simply changing the light bulbs.
The answer to how to change light bulbs might vary from bulb to bulb, but broadly speaking, the solution is simple and pretty much the same. Turn the power back on, and turn the dimmer switch on and see if, with the light bulb on, the dimmer switch is still making the buzzing sound. More efficient light bulbs will not only save you money by cutting down your electricity bills, but they are also more eco-friendly.
It may be the case that you have the incorrect type of dimmer switch installed. In this case, you may need to upgrade the dimmer rating. For a single bulb circuit, you should fit a watt rated dimmer. Now, it is advisable to go one rating higher than the wattage dimmer choice answer you get. This, you should go with a dimmer with a rating of watts, or, preferably, higher. The benefits of choosing an appropriate dimmer switch based on its wattage rating include that it is less likely to result in a short-circuit, and further, the risk of a dimmer switch buzzing or heating will be reduced.
Before assuming that the same rated dimmer switch should be fitted this time round, you should inspect the wattage that the light bulbs consume and confirm. Use the equation from the previous section No.
Replacing a dimmer switch, whether you conclude it should be upgraded or not, is often the necessary solution to fixing a buzzing light dimmer switch. This replacement work is quite difficult and requires precise actions. There is once more safety concerns involved too. Instead of upgrading your dimmer switch rating, you could, of course, install lower wattage bulbs instead. This could prove beneficial in many ways. Firstly, it can save you on energy costs as well as reduce your carbon footprint.
