Bertazzoni Range Hoods FAN-FAILURE-HOOD Error: Exhaust fan motor failure
What Does FAN-FAILURE-HOOD Mean? FAN-FAILURE-HOOD describes a complete or near-complete failure of the exhaust fan motor on a Bertazzoni range hood. With the motor failed, the hood produces no suction regardless of the speed button pressed — grease vapour, steam, and cooking smoke accumulate above the cooktop rather than being captured and exhausted. This is […]
Quick Assessment
Answer to continue safely
Is it safe to keep using?
No. A failed range hood motor leaves the cooktop entirely unvented. Grease vapour accumulation above an active gas or induction cooktop is a fire hazard — arrange motor replacement promptly and use the cooktop only with windows open and adequate natural ventilation until the hood is repaired.
Can I reset the code?
No. There is no electronic reset for a burned-out fan motor. A motor that has tripped its thermal protection will restart after cooling, but a failed winding requires professional motor replacement.
When to stop immediately?
Stop if you notice: Burning smell from the hood motor area during attempted operation, Grinding or screeching noise from the hood when fan is activated.
Symptoms You May Notice
Hood produces no suction and cooking smoke is not cleared from the kitchen
With the fan motor failed, the hood is entirely ineffective — grease vapour, steam, and cooking smoke accumulate above the cooktop, coat the kitchen surfaces, and linger indefinitely regardless of speed setting selected.
Fan motor stops running at all speeds despite buttons being pressed
Pressing any speed button on the hood control panel produces no fan response — no airflow, no motor hum, and no blade movement — indicating a complete motor failure rather than a speed-control issue.
Fan runs at reduced speed or makes grinding or squealing noise
A motor approaching end-of-life may still run but at reduced speed with abnormal bearing noise, indicating imminent complete failure before the motor stops entirely.
Possible Causes
Fan motor windings burned out from service life or overload
The motor winding has failed electrically from normal service life wear or from sustained overload caused by prolonged high-speed operation with severely clogged filters restricting airflow.
Requires ProfessionalMotor thermal protection switch tripped from clogged filter overheating
Heavily clogged grease filters force the motor to work significantly harder to move air, increasing motor temperature until the built-in thermal protection switch trips to prevent winding damage.
DIY PossibleSafe Checks You Can Do
-
1
Clean the grease filters and allow the motor to cool
Switch the hood completely off and remove the aluminum mesh grease filters. If the filters are heavily clogged with grease, clean them (hot soapy water or dishwasher) and allow the hood motor to cool for 30 minutes. Reinstall clean filters and attempt to restart the hood — a thermally protected motor will resume operation after cooling if filters were the cause.
A motor that restarts after cooling with clean filters is still marginal — the thermal trip indicates the motor winding has been stressed. Plan for motor replacement within the next few months.

Check hood power supply
Confirm the hood is receiving power — check the circuit breaker and any inline fuse for the hood circuit. If the hood control panel lights illuminate but no fan response occurs on any speed, the motor itself has failed rather than the power supply.
If the control panel does not illuminate at all, the power supply — breaker, fuse, or connection — is the first thing to resolve before assuming motor failure.
When to Call a Professional
Contact a qualified technician if:
- Motor does not restart after a 30-minute cooldown with clean filters reinstalled
- Grinding or bearing noise from the motor confirms mechanical seizure
- Motor visibly burned or shows melted wiring when inspected by a technician
