An inlet door state control system (200; 300; 400) for an auxiliary power unit (APU) (10) includes an inlet door (34) configured to allow air into an inlet (12) of the APU (10). The system also includes an actuator (32) configured to open the inlet door (34). The system also includes an APU threshold switch (310; 402, 406, 410, 414) connected to the actuator (32), the APU threshold switch (310; 402, 406, 410, 414) configured to automatically change from an open position to a closed position when a predetermined APU operating condition is met. In the system, the actuator (32) opens the inlet door (34) when the APU threshold switch (310; 402, 406, 410, 414) is in the closed position.
