A failed fan motor is the most common reason a Bertazzoni range hood stops moving air entirely. In most Bertazzoni Master Series ranges, this is caused by a burned-out or seized Motovent S3S7/D1 DFS motor assembly. When it fails, the blower stops spinning — smoke, steam, and cooking odours are no longer exhausted, and the hood runs silently with no airflow at any speed setting. ⚡ Common failure point in Bertazzoni-built range hoods after extended high-heat use. Part 603050 is the genuine OEM replacement motor that restores full ventilation performance and quiet DFS operation immediately.

✔ If these symptoms match, this is the most likely failed component in the system.
✔ In most cases, replacing this Motovent fan motor restores full ventilation and quiet operation immediately.
Skill Level: MODERATE — 30–60 minutes. Disconnect power at the breaker before servicing — do not rely on the hood's power switch alone. Remove the grease filters and motor housing cover to access the Motovent assembly, disconnect the wiring harness, and swap the motor unit. Ensure all wire connectors are fully seated and the motor is secured before reassembling. Run the hood on all speed settings to confirm airflow before closing up.
