What F1 Means
F1 means the fan motor circuit isn't responding at all — turning the hood on produces no airflow and the fan stays completely silent.
Common Causes of F1
- Fan motor has failed outright
- Motor wiring or connector has come loose or corroded
- Speed-control board isn't sending power to the motor
🔧 One Safe Check You Can Try
Confirm the hood has power and the speed control hasn't simply been left on the lowest setting before assuming a problem, but don't open the fan housing yourself.
⚠ Why You Shouldn't Go Further Than That
- Reaching the fan motor means removing the housing near live wiring, which is technician work.
- Replacing a motor without confirming the control board isn't the actual problem means paying for the wrong part.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
