The most likely error is that the wire going to the light that stays on is contacting one of the live wires. To check, disconnect all the wires from each other, turn on the breaker and use a voltage tester to identify the live circuit wire.
Why would a light stay on when the switch is off?
The one issue to check is that the bulbs are not CFL’s (fluorescent) or that the bulb is set tight in the base. If not, either might cause intermittent problems. Change the CFL bulb if there is one. Changing a 2 way switch is a simple matter of putting the wires on the terminals (after the power is shut-off).
How do you turn off a ceiling light?
Turn off the light switch powering the ceiling light.
Go back to the room with the ceiling light. If you found the correct circuit breaker, the light will be off. Test it by flipping the switch as needed, then turn the switch down to the off position. Safety is the most important part of changing a light.
Why won’t my LED lights turn off?
These dimmers need a minimum load for correct function which is not achieved by the economical design of LED lamps. If the load falls below the minimum load, the dimmer cannot switch off its output voltage completely even in the off position. As a result the LED continues to glow weakly.
Why won’t my ceiling lights turn on?
If a problem remains, be sure the switch is off, remove the bulb and substitute a new one. If the light does not work with a new bulb, check whether the circuit breaker or fuse governing the fixture has tripped or blown. This often happens when a bulb burns out the moment it is turned on.

Can a broken light switch cause a fire?
Usually, a broken or failing light switch isn’t a fire hazard itself, but it can overheat if the contacts or the switch wear down. Sometimes a bad light switch can cause other components on the circuit, such as a bulb, to become a fire hazard by causing an intermittent current.
Can ceiling lights cause fire?
Light bulbs in enclosed fixtures are also at a high risk for fire because heat is not able to dissipate as well.
How can you tell if a light switch is bad?
Switch Doesn’t Feel ‘Right’
Often your fingers are the best detectors of a faulty light switch. If the switch toggle lever starts behaving differently—losing its “snap” or becoming stiffer than usual—the switch mechanism is worn and should be replaced before there’s trouble.
How can you tell if a light fixture is bad?
Touch the bulb at the bottom of the socket with the other lead. Record the reading. If it’s somewhere close to 120 volts, the fixture is good. If you get a reading of zero or one significantly less than 100 volts, the fixture is bad.
How do you reset a light switch?
Delete the Wall Switch from the iDevices app: For iOS: Tap on the Wall Switch, tap the product name in the upper left-hand corner, scroll down and tap “Delete.” For Android: Tap on the Wall Switch, tap the 3 dots, tap “Edit Product,” scroll down and tap “Delete Product.”
How do you fix a light switch button?
Quote from Youtube video: So first things first you've got to make sure that you flip the switch and your circuit breaker so none of these lights turn on or off because we don't want to get electrocuted.
Do you need an electrician to change a light switch?
Do I need an electrician to replace a light switch? No. If you’re replacing a broken light switch or a like-for-like one, it’s a simple task that only requires you to know how to safely isolate the circuit and some basic tools.
Do light switches wear out?
Why Do Light Switches Go Bad? Just like any other type of simple machine, light switches have several moving parts. Over time, they wear down. Connections can become loose and plastic parts may break.
How often should you replace light switch?
There’s no recommended amount of time for replacing a light switch. They only need replacing if the switch starts to fail. Light switches will commonly last for 20 years or more without any problems.
When should I replace my light switch?
Light Switch Has Buzz, Hiss, Crackle, or Pop Sounds.
This is a sign that the light switch could be arcing because of loose wire connections. If your light switch is making any noises, you should have it replaced to prevent a possible electrical fire.
