Range hood loud, rattling or vibrating

Separate airflow noise (rushing, whistling) from mechanical noise (rattle, grind, wobble). Airflow noise usually comes from a restricted or undersized duct, a stuck damper or dirty filters. Mechanical noise comes from a loose part, a debris-hit or unbalanced fan wheel, or worn motor bearings.
