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 supply is connected and the rocker switch is in the 'on' position. Ensure no obstructions are blocking the fan blades.
• Poor suction: Verify that filters are clean and not clogged. For ducted installations, check for kinks or blockages in the exhaust pipe. For ductless, ensure the carbon filter is not saturated and needs replacement.
• Light not working: Check if the light switch is on. If the LED light is out, contact customer support for assistance as it may require professional replacement.
• Excessive noise: Ensure the range hood is securely mounted. Check for loose parts or foreign objects in the fan assembly.
