Which outcome occurs when an HVAC TXV's thermal expansion bulb loses its thermal contact with the evaporator outlet pipe?

💡 Explanation

The expansion valve closes down, because the bulb no longer senses the evaporator temperature, therefore restricting refrigerant flow and resulting in high superheat, rather than flooding caused by an open valve under excess load.
