🔍 Key Concepts

• Function of a thermal expansion valve (TXV) in a refrigeration/AC system • Common contaminants or conditions that interfere with correct TXV operation • What the valve actually controls and senses (superheat, not line appearance)

💭 Think About

• Ask yourself: Which option would most directly interfere with the valve’s ability to sense and control refrigerant flow and superheat? • Which problems are more likely to be symptoms elsewhere in the system, rather than the root cause of TXV operating difficulty? • Think about what is normally found at the inlet to a TXV and what would happen if that part became obstructed or contaminated.

✅ Before You Answer

• Verify which choice describes a condition that affects the inside of the valve or its immediate inlet screen, not something out in the rest of the system. • Check which option is describing a likely secondary effect instead of the primary operational problem with the valve itself. • Confirm which condition is most commonly cited in refrigeration troubleshooting guides as causing erratic or restricted TXV operation.
