This vent damper is a genuine OEM replacement part that is compatible with various models of Samsung over-the-range microwaves with ventilation systems. It is responsible for regulating the airflow in the microwave venting system. When the microwave is not in use, the damper remains closed to prevent outside air from entering the microwave cavity. However, when you are using the microwave, the damper opens to allow air and steam from the cooking area to be vented out. This helps to remove cooking odors, steam, and excess heat from the kitchen. If the damper is damaged, corroded, or worn down, it will need to be replaced to ensure efficient ventilation and maintain the air quality in your kitchen.
