8. Troubleshooting
If you encounter issues with your range hood, refer to the following common problems and solutions:
- Fan not operating: Check if the power cord is securely plugged in and if the circuit breaker is tripped. Ensure the fan speed button is pressed.
- Lights not working: Verify the light button is pressed. Check if the LED bulbs need replacement (refer to the full user manual for bulb replacement instructions).
- Poor suction: Ensure grease filters are clean and not clogged. For ductless mode, check if charcoal filters need replacement. Verify that the ductwork (if ducted) is not obstructed or kinked.
