    I can't see your oven temperature, but I'm willing to bet with an inlet temperature setpoint of 40 C, and the actual temperature being at 74.2 C, the problem is the inlet is picking up excess heat from the oven since the bottom of the inlet is in the oven.  Your inlet temperature should start at the same temperature as your oven program or higher.

    The GC inlet can't become ready for injection because the actual temperature can't reach the setpoint.  Either raise the temperature setpoint of the inlet or drop the temperature setpoint of the oven.

    Most split/splitless temperature ranges are at 180 C or higher.
