🔍 Key Concepts

• Compressor crankcase "sweating" or frosting usually means it is colder than normal compared to the surrounding space • Think about what happens inside a compressor if liquid (not vapor) gets into it • Compare symptoms of too much liquid vs too little refrigerant in a system

💭 Think About

• What condition inside the compressor would make the crankcase surface temperature drop enough to sweat or frost? • Which option would most likely cause abnormal mechanical noise inside the compressor itself? • If there were a true shortage of refrigerant, would you expect the compressor to get colder, warmer, or possibly overheat?

✅ Before You Answer

• Relate sweating/frosting of the crankcase to low surface temperature and what can cause that • Connect unusual (knocking/hammering) noise to whether liquid or vapor is entering the compressor • Ask whether continuous running or short-cycling alone would normally make the crankcase frost over without another fault present
