Abstract
A refrigerator includes a housing defining a fresh food compartment and a freezer compartment, a fan configured to provide airflow through the compartments, and a damper assembly. The damper assembly includes an airflow passage configured to allow cold air to flow from the freezer compartment to the fresh food compartment, a damper configured to be in an open position under the pressure of airflow flowing through the airflow passage and in a closed position due to a weight of the damper when cold air is flowing through the fresh food compartment. The damper assembly also includes a solenoid element configured to maintain the damper in the closed position regardless of airflow.
