An automatically controlled recirculating high velocity hot air sterilization device includes a housing having a sterilization chamber with a temperature sensor mounted therein, a hot air plenum including a blower in fluid communication with a heating element and sterilization chamber for inputting hor air into and receiving hot air from the sterilization chamber for recirculation, and a control chamber having a temperature sensing circuit connected to the temperature circuit for producing electrical inputs representative of the sterilization chamber temperature, power circuits connected to the heating element and blower, a controller connected to the temperature sensing circuit for monitoring the temperature, and to the heating element and blower circuits for controlling their operation, and a control panel including cycle selection switches for operation, an on/off switch, and temperature and timer/error displays. The controller is designed for monitoring the cycle selection switches and on/off switch, for controlling operation of the heating element, blower and timer for the cycle selected, for monitoring the temperature, for starting the timer when the temperature rises to the required temperature, for restarting the timer should the temperature fall below the required temperature during a cycle, for shutting down the device when a catastrophic failure occurs and for outputting an error signal together with problem information for display.
