Steps

Goal: Confirm the hood has power, rule out the bulb, then isolate the socket or light circuit—or call a pro when needed.

  • Press the fan button or rocker switch. If the fan runs, the hood has power and the light circuit is the cause.
  • Good: Fan runs but light does not turn on—proceed to Check power if needed, then Check the bulb.
  • Bad: Fan does not run—check the circuit breaker and wall switch first. See Fix a range hood that will not turn on for full power troubleshooting.

Check power

Goal: Rule out a tripped circuit breaker or wall switch before touching the bulb or socket.

  • Go to the electrical panel. Confirm the breaker for the kitchen or range hood has not tripped. Reset it if tripped.
  • Check that the wall switch (if present) is on. Some hoods share a switch with the kitchen light.
  • Good: Breaker on and wall switch on. Proceed to Check the bulb.
  • Bad: Breaker keeps tripping when you reset it—there may be a short. Call an electrician.

Check the bulb

Goal: Rule out a burned-out, loose, or wrong-type bulb. Confirm the light has a replaceable bulb.

  • Look at the light housing under the hood. If you see an integrated LED with no replaceable bulb, the light board may have failed—call an appliance technician.
  • Turn off power. Remove the bulb. Check that it is seated firmly. Look for a dark spot or broken filament (incandescent) or blackened base (CFL).
  • Install a bulb you know works from another fixture. Restore power and press the light button.
  • Good: Known-good bulb lights—the original bulb was the fault. Replace with a new bulb of the correct type and wattage.
  • Bad: Known-good bulb does not light—the fault is the socket or hood light circuit. Proceed to Check the socket and light switch.

Check the socket and light switch

Goal: Isolate a faulty socket or light control.

  • Turn off power. Remove the bulb and inspect the socket. Check the center contact—the small tab at the bottom. If flattened, gently pry it up with a small screwdriver. Look for corrosion or discoloration.
  • Press the light button or rocker switch. If the switch feels loose or does not click, replace it per your model.
  • Good: Socket clean and center tab up; light switch works. Retest with a known-good bulb.
  • Bad: Socket corroded or damaged—replace the socket per your hood model or call an appliance technician.

When to get help

Call an appliance technician or electrician if:

  • You have checked the bulb, power, and socket and the light still will not turn on.
  • The hood has an integrated LED with no replaceable bulb.
  • The socket is corroded or damaged and you are not comfortable replacing it.
  • The wiring looks damaged.

Never work on live wiring.

Verification

  • The range hood light turns on when you press the light button.
  • No flickering, buzzing, or sparks.
  • The bulb is the correct type and wattage for your hood and is properly seated.

Escalation ladder

Work from the device outward. Stop when the problem is fixed.

  1. Confirm fan runs Verify the fan runs—rules out power loss.
  2. Power and wall switch Check the circuit breaker and wall switch.
  3. Bulb Check the bulb is snug, not burned out. Try a known-good bulb.
  4. Socket and light switch Check the socket center contact and the light button or rocker switch.
  5. Call a pro Known-good bulb does not work, integrated LED failed, or not comfortable—call a technician.

What to capture if you need help

Before calling support or posting for help, have these ready. It speeds everything up.

  • Whether the fan runs
  • Whether the light has a replaceable bulb or integrated LED
  • Whether a known-good bulb works in the socket
  • Socket condition (center tab, corrosion)
  • Steps already tried

Does the fan run?

Press the fan button or rocker switch. If the fan runs, the hood has power. If not, check the circuit breaker and wall switch.

Press the fan button or rocker switch. Good: fan runs—hood has power; light circuit is the cause. Bad: fan does not run—check power first. See Fix a range hood that will not turn on for full power troubleshooting.

Yes No

Is power on? (breaker and wall switch)

A tripped circuit breaker or wall switch off can cut power to the hood.

Check the circuit breaker for the kitchen—reset if tripped. Check that the wall switch is on. Good: breaker on and switch on—hood should run. Bad: breaker keeps tripping—call an electrician.

Yes No

You can change your answer later.

Reset breaker or turn on switch and test

Reset the circuit breaker or turn on the wall switch. Test the hood. If the breaker trips again immediately, there is a short—call an electrician. If the fan runs after reset, proceed to check the light.

Done

Does the light have a replaceable bulb?

Some hoods have integrated LEDs with no replaceable bulb. If so, a failed LED requires a technician.

Look at the light housing under the hood. Replaceable bulb: you see a bulb socket. Integrated LED: no visible bulb—cannot replace. If integrated LED, call an appliance technician.

Yes No (integrated LED)

You can change your answer later.

Does a known-good bulb work in the socket?

The most common cause of a dead hood light is a burned-out or loose bulb.

Turn off power. Remove the bulb and install a bulb you know works from another fixture. Restore power and press the light button. Good: known-good bulb lights—original bulb was the fault; replace with new bulb. Bad: known-good bulb does not light—fault is socket or hood light circuit.

Yes No

You can change your answer later.

Light working

The light turns on. Replace the original bulb with a new one of the correct type and wattage for your hood.

Done

Is the socket clean and the center contact making contact?

A corroded socket or flattened center contact can prevent the bulb from making contact.

Turn off power. Remove the bulb and inspect the socket. Check the center contact—the small tab at the bottom. If flattened, gently pry it up. Good: socket clean and tab up—retest with known-good bulb. Bad: socket corroded or damaged—replace socket or call a pro.

Yes No (corroded/damaged)

You can change your answer later.

Does the light button or rocker switch work?

The light control may be faulty. Test by pressing and listening for a click.

Press the light button or rocker switch. If loose or no click, replace the switch or control board per your model. Good: switch works—light turns on. Bad: still does not work—call a pro.
