Which of the components shown in the illustration indicates a liquid line solenoid valve? See illustration GS-RA-05.

🔍 Key Concepts

• Follow the liquid line (high‑pressure liquid refrigerant) leaving the condenser/receiver toward the expansion device. • A solenoid valve will have an electrical coil on top of a valve body, usually shown as a box or cylinder with a wire or terminal symbol. • Distinguish between a hand/service valve (manually operated) and an electrically operated solenoid valve in the schematic symbols.

💭 Think About

• First, trace the refrigerant flow from the condenser/receiver to the expansion device and note where any valves are located in that line. Which numbered items sit in this path? • Look closely at the symbols for 8, 11, 13, and 16. Which one clearly shows an electrical component (coil or wiring) attached to the valve body? • Ask yourself which of these components would be used to automatically stop liquid refrigerant flow when the system cycles off, rather than requiring someone to turn it by hand.

✅ Before You Answer

• Confirm that the component you select is installed in the liquid line, downstream of the condenser/receiver and upstream of the expansion device. • Verify that the symbol includes some indication of an electrical coil or wiring, not just a simple manual valve body. • Make sure you are not confusing the solenoid with a filter‑drier or sight glass, which are also typically found in the liquid line but look different in the schematic.
