Range Hood Fan Not Running or No Suction? Broan Motor Assembly S10941066 – Fix Weak Airflow Fast

A failed range hood motor assembly causes your Broan or NuTone range hood to lose suction, run at only one speed, make grinding or humming noises, or stop working entirely — leaving smoke, grease, and cooking odours trapped in your kitchen. In most Broan-built range hoods, this is caused by a failed motor assembly — the 2-speed blower motor that drives the exhaust fan and pulls air through the grease filters and ductwork. When it fails, the fan may not start, run only on one speed, vibrate excessively, or hum without spinning, and ventilation performance drops to zero. ⚡ The most common mechanical failure in Broan and NuTone range hoods. Part S10941066 is the genuine OEM replacement that restores full 2-speed exhaust performance and quiet operation immediately.

❓ Is This the Right Part?

This is the correct fix if ALL of the following are true:

• ✔ Range hood powers on and lights function normally
• ✔ Speed selector switch responds (clicks or changes setting)
• ✔ Grease filters are not severely clogged or blocking airflow
• ✔ ONLY problem is the fan won't run, runs on only one speed, makes grinding/humming noise, or has significantly reduced suction

🔧 Common Symptoms

• Range hood fan won't turn on at either speed
• Fan runs on low speed only — high speed does nothing
• Grinding, rattling, or loud humming noise from the hood
• Weak or no suction — smoke and odours not being captured

✔ If these symptoms match, this is the most likely failed component in the system.

✔ In most cases, replacing this motor assembly restores full 2-speed ventilation and quiet operation immediately.
