If the compressor is not working and passive recovery is being performed, what must be done?

Explanation:
When using passive recovery, the system depends on the compressor to move refrigerant into the recovery device. If the compressor isn’t working, refrigerant can become trapped in the oil inside the compressor crankcase. Releasing that trapped refrigerant from the compressor oil allows all the refrigerant to be captured by the recovery equipment. The other options won’t accomplish recovery: the condenser fan won’t move refrigerant out of the oil, installing a new compressor isn’t required to recover what’s already present, and opening the system to the atmosphere would release refrigerant and is illegal.
