Range Hood Fan Not Working but the Light Is?
If your range hood fan isn't working but the light is, check the fan switch and speed setting, then turn off power before inspecting the filter or wiring. The light can work while a separate fan control, motor, or connection has a problem.

If your range hood fan isn't working but the light is, check the fan switch and speed setting first. If the controls are correct, turn off power before checking the filter or arranging help for a motor, switch, or wiring problem.
A working light only confirms that the light has power. The fan has its own controls and parts, so one can work while the other does not.
Why is the range hood fan not working when the light is?
The light and fan can fail separately because they use different controls and components. A working light doesn't tell you whether the fan switch, motor, or fan wiring is working.
Listen when you press the fan control. No sound points to a control, power, connection, or motor issue, while a running fan with weak airflow suggests a blockage or filter issue.
Check the manual for your hood's control layout and any reset instructions. Don't open the hood's electrical compartment to look for a fault unless you're qualified to work on it.
What should you check first?
Check the fan control, speed setting, and breaker before removing anything. These steps don't require you to touch internal wiring.
- Press the fan control and try each speed.
- Confirm the control isn't set to off or a timer hasn't stopped the fan.
- Check the kitchen breaker once and reset it only if it has tripped.
- If the fan still doesn't run, switch off power before inspecting the filter.
If the breaker trips again, leave it off and call an electrician. Don't keep resetting it or use the hood with an electrical fault.
Can a dirty filter make the fan stop?
A dirty filter can reduce airflow, but it usually won't keep a working fan from starting. If the fan runs but pulls little air, grease buildup or a blocked duct may be the cause.
Switch off the hood before removing a filter, and follow the manual's instructions for washing or replacement. Our guide to cleaning a range hood grease filter explains common filter-care steps.
For recirculating hoods, a charcoal filter helps handle odors, but it isn't a substitute for a grease filter. Learn how range hood charcoal filters work before replacing one.
This Broan-NuTone hood has separate push-button controls for its 3-speed fan and LED light. Its non-ducted setup needs a recirculation filter sold separately.
What if the fan runs but airflow is weak?
Check for a dirty filter, a blocked duct, or a closed damper if the fan runs but airflow is weak. Turn the hood off before cleaning or checking parts you can safely reach.
A grease filter catches cooking residue; a charcoal filter helps reduce odors in a ductless setup. For the difference between two common grease-filter designs, see baffle vs. mesh range hood filters.
Don't reach into the fan or duct while the hood is powered. If airflow stays weak after filter care, use the hood's manual to identify what you can check safely, or contact a qualified repair professional.
The COMFEE' hood has 3 fan speeds and can be installed for ducted exhaust or recirculation. Follow its manual when cleaning the filter or checking the installation mode.
When should you stop troubleshooting and call for help?
Stop if the breaker trips again, you smell burning, see damaged wiring, or hear unusual grinding. Switch off the hood and circuit if you can do so safely, then contact an electrician or appliance repair professional.
A fan that stays silent after you check its controls and breaker may have a failed switch, connection, or motor. The light working doesn't make it safe to open the hood or handle its wiring.
For routine care, clean stainless steel surfaces with the method in our guide to cleaning a stainless steel range hood. Follow the manual for electrical issues and repairs.
What should you do if the range hood fan is still not working?
If the range hood fan isn't working but the light is, check the fan controls and breaker, then clean an accessible filter if the fan runs with weak airflow. If the fan stays silent or a breaker trips again, leave electrical troubleshooting to a qualified professional.
For ductless hoods, confirm the correct filter is in place after cleaning. For more on how that setup handles cooking air, read how a recirculating range hood works.
Frequently asked questions
Why does my range hood light work but the fan does not?
The light and fan use separate controls and components, so a working light doesn't prove the fan circuit is working. Check the fan switch and speed setting first.
If the hood has power but the fan stays silent, stop using it and consult its manual or a qualified repair professional.
Can a dirty filter stop a range hood fan?
A clogged filter can restrict airflow, but it usually doesn't explain a fan that won't start or make any sound. Turn off power before removing and cleaning a grease filter, then check whether the fan runs.
Follow the hood's manual for cleaning and filter replacement.
Should I reset the breaker if my range hood fan stops?
You can check whether the kitchen circuit breaker has tripped, but don't repeatedly reset a breaker that trips again. Turn the hood off first.
If the breaker won't stay on, leave the circuit off and contact an electrician.
Is it safe to repair a range hood fan myself?
Limit checks to controls, the breaker, and filter care described in the hood's manual. Switch off the circuit before any inspection that involves removing a cover, and don't touch wiring or internal parts unless you're qualified.
Call a repair professional if the motor, switch, or wiring may have failed.
