When recovering refrigerant from a system that experienced a compressor burnout, watch for signs of ______ in the oil.

When a compressor burns out, lubricating oil often carries debris from the damaged internals. The key idea is that oil contamination is a direct sign of the burnout and the resulting damage in the compressor. You’re looking for contaminants such as metal fragments, carbonized oil, and other debris in the oil, which indicate that the system has been compromised and needs thorough cleaning and component replacement as part of the recovery and reconditioning process. Other signs like viscosity change or color change can happen for reasons other than burnout (oil aging, wrong oil, oxidation), so they’re less specific indicators. Dirt buildup is a form of contamination, but stating contamination covers the broader, more definitive sign you’d expect after a burnout.
