Bosch B20cs80sns/01 Parts

This damper assembly controls oven vent airflow so the oven reaches and holds the correct temperature and venting. Replaces a worn or stuck vent flap to restore normal oven cycling and heat distribution. What it does:

• Opens and closes the oven vent to regulate airflow during bake, broil, and self-clean cycles
• Helps the oven maintain temperature by allowing excess heat to escape when needed
• Commonly linked to symptoms like uneven baking, persistent high internal temperature, or a stuck vent that won't open
• Functions as a direct replacement part when the existing vent flap or actuator is damaged or fails

• Disconnect power to the appliance before attempting service
• Access may require removing the oven rear panel or control housing; follow the OEM service manual
• Handle the damper gently to avoid bending the flap or damaging the actuator linkage

This replacement access cover restores the appliance's exterior finish and protects internal components from dust, debris and accidental contact. It helps keep parts secure while maintaining the original appearance. What it does:

• Shields internal wiring and components from dirt and loose objects
• Prevents accidental contact with moving or electrical parts
• Helps reduce noise by securing loose openings or panels
• Restores a finished look when the original cover is cracked, missing, or damaged

• Disconnect power to the appliance before beginning any work.
• Use basic hand tools to remove mounting screws and install the cover; keep fasteners for reassembly.
• Handle edges carefully to avoid cuts and align tabs before seating the cover.
