    In my property, I changed light bulbs that are connected on the lower and upper switch of the inside stairs. I’m not sure if both switches are the problem? Can someone help me please?

  2. Dave Rongey says:

    Hi William,
    The circuit wiring in the bathroom should be tested to make sure the voltage is present, and to make sure the neutral wire is connected and working properly. If either wire of the circuit is not working then each section of the circuit should be tested and evaluated individually. It is possible that a wire splice has failed due to a loose or burnt connection. If this is found then appropriate repairs will be required.
    Thanks for sharing William. We hope this will help to repair the problem with your vanity circuit.

    My bath vanity lights will not work. I changed the switch and checked the tabs in the light sockets. I tested the lamp on a different circuit and the lights worked. I installed the lamp in the vanity light fixture and they didn’t work.

    Josh,
    The dimmer switch was on while you changed the light bulb when the light bulb popped, so this damaged the dimmer switch and so the dimmer switch will need to be replaced.
    This a good example of why you should never replace light bulbs while the switch is on, especially dimmer switches because they are very sensitive and can be easily damage.
