Electrical Question: Why do my ceiling fan lights flashing on and off?

  • When I turn on my ceiling fan the light fixture keeps flashing on and off, as if I am turning a dimmer switch high then low.

Thanks for your electrical question Edward.

Why Ceiling Fan Lights are Flashing On and Off

  • This problem is most likely due to installing lights that are too high in wattage.
  • The only way to fix the issue is to install the right size bulbs as specified by the ceiling fan manual.
  • The national efficiency code standards now requires all ceiling fan manufactures to install limiters in new ceiling fans.
  • It basically cuts of power when too much wattage is drawn through the fixture.
