Symptoms
- Fan doesn't turn on at any speed
- Light works but the fan doesn't
- Clicking sound with no fan movement
- Fan worked intermittently before failing completely
Likely causes
- CommonTripped breaker or blown fuseThe hood's dedicated circuit may have tripped from an overload or short.
- CommonFaulty fan switchThe switch controlling fan speed can wear out or fail electrically over time.
- PossibleWorn or seized fan motorYears of grease buildup or normal wear can cause the motor to bind or burn out.
- PossibleBlown motor capacitor (on some models)A failed capacitor can prevent the motor from starting even though it hums.
What to do
- Check the breaker panel for a tripped circuit related to the kitchen or range hood.
- Test the light to confirm the unit has power at all; if the light works but fan doesn't, focus on the fan switch or motor.
- Turn the fan on and listen closely for a humming sound with no movement, which suggests a seized motor or bad capacitor rather than no power at all.
- Turn off power at the breaker before removing the grease filter and cover to inspect the fan blade for buildup or an obstruction.
- Clean any heavy grease buildup off the fan blade and motor housing, which can sometimes free a sluggish motor.
- Replace the fan switch or motor if cleaning doesn't restore function, matching the exact part for your model.

When to call a pro
Call an appliance technician or electrician if the breaker and switch check out fine but the fan motor doesn't run, since motor replacement involves wiring work.
Safety
Use caution
Turn off power at the breaker before removing covers or touching internal wiring or the motor.
