Which outcome occurs when thermostatic expansion valve fails in an evaporator with R-134a refrigerant?

💡 Explanation

When a thermostatic expansion valve fails open, excessive refrigerant flows into the evaporator coil because it bypasses its metering function, resulting in liquid floodback to the compressor, which can damage valves and bearings. Therefore liquid floodback results, rather than freezing, overheating, or high-pressure lockout, which involve other distinct component failures.
