Electrolux Microwave Damper & Related

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

This damper assembly controls airflow between the freezer and refrigerator compartments to help maintain even temperatures. Replaces a faulty damper to restore proper cold-air distribution and reduce temperature imbalances. What it does:

• Opens and closes to regulate cold air flow from the freezer into the fresh-food compartment.
• Commonly used when the refrigerator section is too warm while the freezer remains cold.
• Can stop excessive air flow that causes frost build-up or noisy operation.
• Works with the fridge's control system to modulate compartment temperatures.

• One damper assembly

• Disconnect power before starting work to avoid electrical hazard.
• Access typically through the fresh-food or freezer interior; remove panels as needed.
• Handle the actuator and wiring carefully; ensure connectors are fully seated.
• Test operation after installation and reassemble panels securely.
