Light Bulb and Dimmer Switch Compatibility

Understanding How Dimmer Switches Work with Light Bulbs

Ceiling Fan Light Bulbs and Dimmer Switch Issue
Electrical Question: I have a ceiling fan with a light on a dimmer. The fan works but the light stopped working. The weeks prior to the lights not working, I would turn the dimmer on and nothing would happen for a few seconds, then the light would turn on.
Eventually, the light stopped working all together. Next to the dimmer is a switch for the fan. The fan works fine.
How do I solve this problem? Is it the light fixture or the switch?

    Light Bulb and Dimmer Switch

    I am replacing my ceiling fans that have dimmer switches on them. I have bought Hunter fans with candelabra bulbs on them which I am told are not compatible with dimmer switches. Since my dimmer switches worked on my old fans does this mean my old fans were wired to work with these candelabra bulbs?

    • Dave Rongey says:

      Hi Maurice,
      A standard incandescent candelabra light bulb is compatible with standard dimmer switches. Typically, if a light bulb does not have the dimming capability it will be labeled Non-Dimmable.
      Thank you for sharing your light bulb question with us,
      Dave
