A motorized damper door assembly for use in freezing temperature applications includes a damper frame, a damper door having a mounting portio n rotatably mounted to the frame, and a seal member having a vertically extending moisture barrier adjacent the mounting portion. The door mounting portion an d the moisture barrier together form a reservoir inside the door mounting portion to prevent moisture from seeping directly into the motor housing below the door mountin g portion. Consequently, as moisture accumulation in the motor housing is avoided, associated damper jamming and impaired performance issues are also avoided.< /SDOAB>
