Customer Questions and Answers for Hood Damper (Assembly) by Ge

This hood damper assembly opens to allow exhaust airflow and closes to help block outside drafts and odors when the fan is off. It restores proper venting and prevents back-drafts in over-the-range hoods and microwaves. What it does:

• Opens with the vent fan to let cooking smoke and steam exit the home.
• Closes when the fan is off to reduce backdrafts, outside air, and odors.
• A faulty or stuck damper can cause reduced airflow, rattling noises, or air blowing back into the kitchen.
• Works as the moving flap between the appliance exhaust and the ductwork to control airflow direction.

• Disconnect power to the appliance (unplug or shut off the circuit breaker) before servicing.
• Access typically requires removing the hood or microwave grille/cover; keep track of screws and mounting hardware.
• Basic hand tools (screwdrivers, possibly a nut driver) are usually sufficient; handle the damper flap gently to avoid bending.
• After installation, restore power and run the fan to ensure the damper opens and closes smoothly.
