When recovering refrigerant into a non-pressurized container from a refrigerator with an improper compressor, what is described as necessary?

When a refrigerator’s compressor isn’t operating properly, you may need a temporary method to get the refrigerant into the recovery cylinder rather than venting it. Heating the compressor helps loosen any seized or sticking internal parts, and a gentle strike with a rubber mallet can free them enough for the compressor to start pumping again. This allows continued recovery into a non-pressurized container, which is the goal instead of releasing refrigerant to the atmosphere. It’s a targeted, temporary step used to salvage refrigerant when the compressor is not functioning smoothly; if the compressor still won’t free after this, you would reassess the situation. Venting to atmosphere and stopping recovery entirely without attempting to free the compressor are not appropriate, and replacing the compressor is a separate, more extensive action, not the immediate necessity described here.
