🔍 Key Concepts

• Heat transfer between crankcase and surrounding air • Effect of refrigerant charge on compressor temperature and sweating • Relationship between oil circulation and crankcase temperature/appearance

💭 Think About

• Think about what causes surfaces to sweat or condense moisture in the air and whether that points to being unusually cold or unusually hot. • Consider how an incorrect refrigerant charge would affect the temperature of the compressor crankcase during operation. • Ask yourself whether more or less lube oil flow would typically make the crankcase run cooler or hotter.

✅ Before You Answer

• Decide if sweating means the crankcase is cooler than normal or hotter than normal. • Match that temperature condition with which fault (oil circulation vs. refrigerant charge vs. compressor loading) would most realistically cause it. • Eliminate any options that would logically make the crankcase warmer, since sweating usually indicates a surface that is at or below the dew point temperature of the surrounding air.
