🔍 Key Concepts

• Effect of moisture inside a sealed refrigeration system • How ice formation affects the expansion device (valve or capillary) • Long‑term effects of water + refrigerant + oil on metal parts and motors

💭 Think About

• For each option, ask yourself: could the presence of water physically or chemically lead to this problem? Think through the mechanism. • Consider what happens when moisture reaches the coldest points in the system. Where are those points located? • Think about how acids can form inside a refrigeration system and what components those acids might damage.

✅ Before You Answer

• For each choice, decide: can moisture alone reasonably cause this specific failure mode? • Recall whether ice blockages are a common troubleshooting issue in refrigeration systems. • Remember that corrosion and electrical insulation breakdown can be related to contaminants like moisture.
