How do I fix my light switch? I checked my circuit breaker and that's working. I replaced the switch with a new switch and it still doesn't work.
You might look to see if the outlet is GFI protected. It is possible the GFI (Ground Fault Interrupter) tripped and needs to be reset.
If so, push the red button (reset button) firmly until it stays down (pushed in). If it does not stay closed, replace it.
Also check your light bulb fed by "the switch that does not work", to make sure it did not burn out.
Your switch could be good, but the bulb bad.
If your light switch is not on a GFI circuit and both Lutron switches are fed by one breaker, get a volt-ohm meter, set it to the volts in a voltage range to read house hold voltage (around 121 volts), and check to see that both switches are receiving 121 volts. Usually you measure with the black probe touching a white (neutral) wire, while the black wire is usually the wire that is in series with the lamp. A black wire may come into the switch and leave as a black wire going to the bulb. If you do not have full voltage reaching your switch, you may have a wiring problem where a wire is no longer making good contact. If you are not sure about how to test with a volt meter, search on your tube for further explanations on how to test to see if a light switch is good.
