The existence of inverted start conditions in a refrigeration chiller (10) is identified by sensing the liquid level (64, 68) in the chiller evaporator (20). That liquid level (64, 68) is indicative of the location of the chiller's refrigerant charge at start-up. If the sensed liquid level (64, 68) is below a predetermined level, an inverted start condition is verified to exist. Failed starts and chiller system shutdowns are reduced or avoided.
