Ceiling Light Doesn T Switch Off

Both switch types have 4 wire connections.

Ceiling light doesn t switch off. Verify how many discrete capacitors black parts are in the housing where the fan switch is located. By far the most common problem is a loose wire connection at the switch itself which is subject to constant on off usage. Screw them into. If things look good return light bulbs that are in working order into their sockets.

2 you would want to be fairly certain the outlet has little metal tabs that connect top and bottom on each side. Light will not turn off using light switch 1 some electrical outlets have metal tabs on the side that connect the upper and lower receptacles. You can test the switch with a voltage tester to determine which is the problem. If a dual capacity switch is installed in a fan with just one capacitor the fan will not turn off.

Less commonly a light bulb socket may go bad. This means that there is a low voltage in the ceiling light even when it is switched off which causes the led to light up weakly. A typical non contact voltage detector ncv and a typical mains tester. In this way the pull chains on the fan will operate the lights and fan as you wish.

Look inside of the light bulb socket to make sure there are no burn marks or charred spots. Removing the wire nuts from the wires connected to the switch will help. You must remove the cover plate and switch to expose the joint. If you see black or burned areas this may be a sign that your ceiling fan light kit has a wiring issue.

If a light switch won t turn off it could be because it s miswired or just a bad switch. If so you will need to replace the socket. If the switch is miswired it s easy to rewire. Finding which wires go to a switch using a multimeter at least catii 600v rated on an isolated circuit off at fusebox and tested for no 240v ac.

This could be on the switch itself at the circuit breaker panel or in a pass through wire connection in the wall box or ceiling box. A single capacitor switch and a dual capacitor switch. If the switch is bad you should replace it because you can t fix it. Here the voltage carrying conductor can induce a voltage in the conductor separated from the switch.

Your fans and the fan lights work just fine because they are always getting power from the black unswitched wire in the ceiling box.
