Symptoms
• Range hood fan does not turn on when speed buttons are pressed
• Fan runs inconsistently or at only one speed setting
• Fan makes unusual grinding or squealing noises before error appears
• Display screen shows F01 error code
• Fan suddenly stops working mid-operation
• Range hood lights may work but fan remains inactive
• Error code persists after attempting to change fan speed
Possible Causes
• Loss of 120V power supply to the fan motor circuit or control board
• Faulty capacitor preventing fan motor from starting
• Fan motor bearing failure or internal motor damage
• Wiring connection loose or disconnected inside the range hood
• Control board malfunction or failure in the USA 60Hz circuit
• Fan blade obstruction from grease buildup or foreign debris
• Failed thermal overload protection on the motor
• Defective fan speed control relay on the circuit board
Safety Checks You Can Do
• Check your home electrical panel to ensure the circuit breaker supplying the range hood has not tripped; reset the breaker if necessary
• Verify the range hood is plugged into a dedicated 120V outlet or hardwired correctly per installation instructions
• Turn off the range hood at the power source and wait 60 seconds, then turn power back on to perform a hard reset
• Remove and inspect both the aluminum grease filters and any additional charcoal filters for heavy grease buildup; clean or replace filters as needed
• Check the exhaust duct pathway outside your home to ensure no lint, debris, or ductwork kinks are blocking airflow
• Open the range hood access panels (if your model allows safe user access) and look for visible obstructions around the fan blades
• Visually inspect any exposed wiring connectors inside the hood for loose connections or corrosion
• Ensure nothing is resting against or blocking the fan motor area
• Try operating the range hood at different fan speed settings to see if the motor responds at any speed level
Safety First
