🔍 Key Concepts

• Behavior of refrigerant in the crankcase during the off cycle • Effect of temperature on how much refrigerant dissolves in lubricating oil • Common problems caused when liquid refrigerant is mixed with crankcase oil at startup

💭 Think About

• Think about what happens to refrigerant when the compressor is not running and the crankcase is cold versus warm. • Ask yourself which problem, if not controlled, could lead to foaming, poor lubrication, or possible damage on the next start. • Consider how temperature affects the solubility (how much can be absorbed) of refrigerant in oil compared to moisture or the formation of wax and gum.

✅ Before You Answer

• Identify which choice directly involves refrigerant–oil interaction rather than other contaminants like moisture or acids. • Recall that warming the crankcase slightly will tend to drive something out of the oil rather than pull more into it. • Eliminate any options that describe issues not commonly associated with refrigeration compressor crankcase heaters (e.g., wax/gum formation).
