When a compressor burnout happens you take a sample of

• A. Oil
• B. Refrigerant
• C. Water
• D. Coolant

Answer: (A)

Sampling the oil is the best choice because oil carries everything that happens inside the compressor. When a burnout occurs, internal components such as bearings or moving parts shed metal particles and contaminants into the oil. An oil analysis can detect these metal fragments, varnish, or abnormal acidity, all of which point to internal damage from a burnout. Refrigerant, water, or coolant samples wouldn’t directly reveal the burnout condition inside the compressor, so they’re not as informative for diagnosing this issue. An oil sample gives the most direct evidence of a compressor burnout and helps guide the repair plan.
