60 second blower delay on heat pump

Hello, I have a Trane package unit. I think I have an issue. The fan on top of the unit comes on 30 seconds or a minute before the blower comes on and starts to push air through the vents. A 15 microfarad capacitor was metered to 13 microfarads and replaced with a known good (15 microfarad) capacitor. Is it normal for the fan to run before the condenser or blower motor turns on?
