An automated banking machine (10) includes a lockable first fascia portion (20) which when unlocked enables access to a chest lock input device (104), inputs to which enable opening a chest door (18) of the machine. Opening the first fascia portion also enables access to an actuator (116) which enables moving a second fascia portion (22) for conducting service activities. A baffle structure (164) is positioned on the housing adjacent the second fascia portion to enable cooling air flow within the housing of the machine and to prevent the introduction of moisture into the housing. A controller (72) in the machine selectively illuminates light emitting devices (118, 126) for purposes of facilitating user operation of the machine. Servicing the machine is facilitated through use of a portable diagnostic article (98) which enables the controller to access diagnostic data stored in memory.
