Dimmer Switch Not Working - What Happens If You Use A Non Dimmable Bulb With A Dimmer Switch?

So, what happens if you use non-dimmable LEDs on a dimmer? Well, at best the bulb just won't dim properly. At worst, though, you might damage the bulb. You see, dimmable LEDs have special circuitry inside that allows them to respond to varying current levels or “pulsing” current waves to produce a dimming effect.

Why does my 3-way dimmer switch not work?

It sounds like someone has put a single pole switch in a system that needs two three ways. Part of the problem is that there needs to be the right wiring between the switches. There has to be two hot wires*. There also may need to be a neutral wire, depending on the wiring configuration.

Do all dimmer switches require a neutral wire?

Most don't, because they are designed to drop in and replace standard light switches which are usually not provided with a neutral connection. It is possible that some smart dimmers might need neutrals, because they have to have somewhere to dump the current that runs the radio receiver when the lamp is off.

Do I need to turn off power to replace light switch?

First and foremost, before getting started you should shut off the electrical power to your entire house.

When replacing an outlet receptacle or light switch it's possible to turn off an individual circuit.

Why would my dimmer switch stop working?

Any mechanical component is prone to wear and tear, degrading performance over time. And, although a dimmer switch is an electrical fixture, it still needs moving parts, and those parts can wear down. Dimmer switches can all start to misbehave because of damage, or simply because the switch itself was defective.

Why are there two black wires on a dimmer switch?

The two black wires connecting to the black leading to the switch are supplying power to the switch/dimmer. The blue wire from the switch connected to the other black wire is the switched-hot going to the light. The green wire is the ground.

Is a dimmer switch wired the same as a normal switch?

Dimmer switches don't need special wiring at all. Single-pole dimmer switches can just replace existing single-pole light switches, and 3-way dimmers can easily replace a standard 3-way switch or be used as a single-pole switch with one wire capped off.

What does L1 and L2 mean on a dimmer switch?
