Range hood or oven vent hood light doesn't work

A dead hood light is usually a burned-out bulb, but a hood light that's part of a shared circuit can also point to a switch or wiring issue if a new bulb doesn't fix it.

Likely causes

  • CommonBurned-out hood light bulbRange hood bulbs are a wear item and burn out over time like any bulb.
  • CommonBulb not properly seatedA loosely seated bulb, especially after a recent change, can fail to make contact.
  • PossibleFaulty light switch on the hoodThe switch itself can fail separately from the bulb or fan.
  • Less commonWiring issue at the light socketA damaged or loose wire at the socket can prevent power from reaching a good bulb.

What to do

  1. Turn off power to the hood at the switch or breaker before replacing the bulb.
  2. Remove the light cover or lens per your hood's design, usually held by clips or screws.
  3. Check the bulb for visible blackening or damage, and try a known-working bulb of the correct type as a test.
  4. Ensure the new bulb is the correct wattage and type specified for your hood.
  5. Reinstall the cover and restore power to test.
  6. If a new bulb doesn't work, check that it's seated fully and try wiggling it gently to confirm contact.
  7. Have a technician check the socket wiring or light switch if a confirmed good bulb still doesn't light.
