Ok, 40 is excessive freezer compressor run which means the control basically thinks the unit has been running too long to reach temperature.
24 is a defrost under heat. This means the control didn't see the defrost thermostat open.
05 is a refrigerator cabinet thermistor reading open for 10+ seconds.
All these issues are most likely a fluke, or thermistor errors. Press and hold the alarm button for 15 seconds until the service clears. If the error(s) come back, you'll want to call sub zero to get a servicer to your home. These units are very complex and aren't really meant to be serviced by a novice.
