Thermal Expansion Valve (TXV)
A failure of the internal diaphragm or sensing bulb in the TXV causes it to stick in a restricted position, starving the evaporator of refrigerant. This restriction leads to a sharp decline in suction-side pressure, forcing the coil temperature below the frost point and causing atmospheric moisture to freeze on contact. As the ice layer grows, it physically chokes the airflow and insulates the coil, preventing the system from cooling the air passing through it.
