Parts for Broan QS3: Range Hood Parts

This is a metal duct connector plate designed to attach a 7-inch round duct to a range hood vent housing. It provides a secure transition between the hood exhaust outlet and the ductwork, often incorporating a damper function to prevent backdrafts. Replace this plate if you notice air leaking around the duct connection, a rattling noise during operation, or if the existing plate is damaged or corroded.

This is a vent damper that mounts at the duct connection point of a range hood. It opens to allow exhaust air to flow out during operation and closes when the hood is off to prevent outside air, drafts, and pests from entering through the ductwork. Replace this part if you feel cold air blowing back through the hood when it is off, notice increased odors or drafts in the kitchen, or the damper flap is stuck or visibly damaged.
