The first sign of trouble is when the switch begins to behave in a fashion that is abnormal in any way.

Wall light switch only works in the middle.

When i replaced i didn t care much about the travelers as i read in several diy sites that it didn t matter. If the switch won t turn off the lights it s probably because you bypassed it somehow. Wiring a 3 way light switch is certainly more complicated than that of the more common single pole switch but you can figure it out if you follow our 3 way switch wiring diagram. Guide to wiring multiple light switches electrical problem.

One of the plugs is always on and the other is controlled by the wall switch. You might want to consider a lighted switch in some cases such as having a light that dimly glows if the switch is off. This morning i replaced two 3 way switches that control a hallway ceiling light and now it works on only one position. A third problem that might be blamed on the light switch can actually caused by the light fixture itself.

Because the electrical code as of the 2011 nec update requires a neutral wire in most new switch boxes a 3 wire cable runs between the light and switch. One switch controls the hallway light the other controls the outside light and one is not used. A wall switch is a mechanical device with moving parts that gets thousands of uses over the course of its lifespan so it s no surprise that switches eventually wear out and go bad. You could consider replacing one of the switches in 4 and or one end of line switch in 3 with a 3 way dimmer.

More than likely not but it is possible that if the contacts of the switch make partial contact that it could allow some of the voltage to pass but due to the partial connection would cause a voltage drop which in turn produces heat thus creating a fire hazard as well as possible damage to the contacts. Get one rated for leds and replace incandescent bulbs with leds. Why did my light switch stop working. Wiring a 3 way light switch.

I checked the circuit breaker and it was good. I went to turn on the outside light and it would not work. Screw the switches back into their boxes put the switch plate covers on and turn the power on to test the switches. Although the principle of light switch wiring is fairly basic things can sometimes get confusing when the switch is in the middle of a circuit or it controls more than one light and there are multiple wires in the electrical box.

This can be caused by different events. The red and black are used for hot and the white neutral wire at the switch box allows for powering a timer remote control or other programmable switch. I have a 3 way light switch that is not working. A wire getting loose in a terminal screw or in a wire connector at the switch or light fixture could cause the flicker.

Both switches had one black wire connected to the common and then red and white connected to the travelers. You might notice this type of issue if the light bulb flickers while turned on. If your 3 way circuit uses an outlet or outlets instead of light fixtures you might get confused with the wiring if the outlets are split.
