Ceiling Light Doesn T Switch Off

A single capacitor switch and a dual capacitor switch.

Ceiling light doesn t switch off.

If the switch is miswired it s easy to rewire. Removing the wire nuts from the wires connected to the switch will help. 3 if you have only 1 wire instead. You must remove the cover plate and switch to expose the joint.

Use a continuity tester to see which red black pair are connected disconnected by the switch. If a dual capacity switch is installed in a fan with just one capacitor the fan will not turn off. 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. Verify how many discrete capacitors black parts are in the housing where the fan switch is located.

In this way the pull chains on the fan will operate the lights and fan as you wish. A typical non contact voltage detector ncv and a typical mains tester. Your fans and the fan lights work just fine because they are always getting power from the black unswitched wire in the ceiling box. By far the most common problem is a loose wire connection at the switch itself which is subject to constant on off usage.

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. The wiring joint behind the switch on the wall can also fail. If things look good return light bulbs that are in working order into their sockets. If you see black or burned areas this may be a sign that your ceiling fan light kit has a wiring issue.

Look inside of the light bulb socket to make sure there are no burn marks or charred spots. Less commonly a light bulb socket may go bad. Screw them into. 2 you would want to be fairly certain the outlet has little metal tabs that connect top and bottom on each side.

If so you will need to replace the socket. If the switch is bad you should replace it because you can t fix it. 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. Both switch types have 4 wire connections.

Here the voltage carrying conductor can induce a voltage in the conductor separated from the switch.
