Symptoms
- Light doesn't turn on while the fan works fine
- Light flickers before going dark
- Both bulbs out at once on a two-bulb hood
- Switch clicks but nothing happens
Likely causes
- CommonBurned-out bulbRange hood bulbs endure heat and grease exposure and burn out faster than typical household bulbs.
- PossibleWrong bulb type or wattage installedUsing a bulb that doesn't match the fixture's rating can cause it to fail quickly or not light at all.
- PossibleFaulty light switchThe switch itself can fail electrically even if the bulb is fine.
- PossibleLoose or corroded socket connectionGrease and heat exposure over years can degrade the socket contacts.
What to do
- Turn off power at the breaker before touching the bulb or fixture.
- Remove the light cover (if present) and check the bulb, replacing it with the exact type and wattage specified for your hood.
- If both bulbs are out simultaneously, suspect the switch or wiring rather than two coincidental burnouts.
- Check the socket for corrosion or looseness and clean gently if accessible.
- Test the switch itself if a new bulb doesn't fix it, replacing it if it's confirmed faulty.
