🔍 Key Concepts

• Refrigeration compressor lubrication system and what the sight glass can tell you • How overheating, air, moisture, or metal wear typically show up in oil appearance • Difference between discolored oil vs metallic or foamy oil

💭 Think About

• If the oil is brownish, what physical or chemical changes to the oil could cause this color change? • Which option would most likely produce metal particles or scoring rather than a color change alone? • How would moisture usually show up in a sealed refrigeration system—what kinds of symptoms or deposits would you expect?

✅ Before You Answer

• Identify which choice involves metal-to-metal wear and think about whether that would make the oil just brown or give it a shiny/metallic look • Consider which fault would cause overheating/oxidation of oil and possible carbon deposits, changing its color • Rule out options that would more likely cause gas leaks, foaming, or pressure problems rather than primarily a color change in the oil
