Description

This vent damper assembly keeps outside air and pests from entering the appliance while allowing exhaust to exit freely. It restores proper airflow and helps prevent cold drafts or backflow when the appliance is off. What it does

• Serves as the one-way flap for the external vent, opening during exhaust and closing afterward.
• Stops outside air and pests from entering the ducting when the appliance is idle.
• Helps reduce backdrafts that can affect drying or venting performance.
• Can reduce stray airflow and cold drafts into the laundry area.

What's included

• One vent damper assembly.

Install notes

• Always disconnect power (and gas supply for gas appliances) before servicing.
• Access typically from the rear vent outlet or through the exterior vent hood; basic hand tools required.
• Ensure correct orientation so the flap opens outward with exhaust airflow.
• Inspect surrounding seal and ductwork; replace any damaged screws or gaskets during reassembly.
