• Opens freely with exhaust fan operation to allow proper ventilation
• Commonly replaces units that are stuck, bent, noisy, or no longer closing fully
• Helps reduce drafts and unwanted odors entering the home through the duct

• One damper

• Turn off power to the appliance before accessing the damper to avoid injury
• Access may require removing the hood cover or grille—use basic hand tools
• Inspect mounting screws, gaskets, and surrounding ductwork and replace any damaged hardware
