Why does my light switch not turn my light off?

Why does my light switch not turn my light off?

The most likely error is that the wire going to the light that stays on is contacting one of the live wires. Other wires connected to it are probably supplying power to outlets and the light fixture wire may be mixed in. To check, touch each wire in turn to the circuit wire, wearing rubber gloves for safety.

Why have my lights suddenly stopped working?

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. Reinstall the bulb and test the fixture again. If the light still does not work, examine the wiring.

Why is my light always on?

Either your switch is defective or you have tied the hot wire and your switch leg together somewhere that is causing the light bulb to always be on. Turn your electrical power off and if you can identify the circuit breaker that feeds that particular area or room so much the better.

What do you do when your lights wont turn on?

If a new bulb doesn’t work, turn off the switch or pull the plug (turn off the power, that is), and try bending up the little metal tab inside the bulb socket. These can get pressed in so far that they no longer touch the bulb’s electrical contact.

Can a bad light switch cause a fire if the light switch is turned off?

Answer: An outlet always has power to it as long as the breaker is turned on, so yes it can start a fire when there is nothing plugged into it. A light fixture that is turned off, on the other hand, would be very unlikely to cause a fire.

  5. Solution 5: Talk to the manufacturer of the LED lamp.

Why do my LED lights stay on even when the switch is off?

In contrast to incandescent bulbs or halogen lamps an LED lamp has a high resistance due to the integrated power supply unit. The serial connection of the glow lamp closes the circuit even when the switch is turned off. As a consequence a low voltage drop appears to the LED driver so the LED still lights up weakly.

How do I test my power light fixture?

  1. Turn the power off to the socket.
  2. Test the socket by attaching the clip of the continuity tester to the hot screw terminal, the black wire lead. Then, touch the probe to the metal tab in the bottom of the socket.
  3. The tester should glow. If it doesn’t, the socket is faulty and needs to be replaced.
