The appliance door is closed to create an insulated area and the interior surface of the appliance door includes a module-engaging connector. The module is typically removably engaged within the appliance door and includes an insulated compartment within the module and a compartment door as well as a lock for the compartment door. The module also includes a utility connector that engages the appliance door and operably engages the module-engaging connector of the appliance door so that the module receives at least electrical power from the appliance.
