Customer Questions and Answers for Damper Assembly (Exhaust Vent) by Frigidaire

This damper assembly controls airflow for the exhaust vent, opening with the blower and closing when off to block backdrafts. Replace a cracked, missing, or sticking damper to restore proper venting and reduce noise and drafts.

• Opens during fan operation to let cooking air exit through the duct; closes when off to prevent outside air from entering
• Helps maintain correct airflow to capture steam, smoke, and odors
• Common symptoms: poor venting, rattling/clacking noises, cold air drafts through the unit, visible broken or missing flap
• A stuck or binding damper can cause louder fan noise and weak airflow

• Disconnect power before servicing; remove the vent cover/adapter to access the damper
• Note airflow arrow and hinge orientation; install so the flap swings freely in the exhaust direction
• Reuse existing screws and seals; replace any damaged foil tape or gaskets to prevent leaks
• After installation, run the fan to ensure the damper opens/closes smoothly without rattling
