Through this bulletin climatemaster will attempt to offer some clarity and certainty when diagnosing possible txv problems. Some txvs are set to maintain a specific superheat from the factory, but a few are adjustable. (reprinted from refrigeration service today) assumptions & possible causes. The purpose of a txv is to maintain. Room temperature too high, with high superheat: As we enter the cooling season, we must install, operate and maintain thermal expansion valves (txvs). Replace expansion valve with valve having external pressure equalization. Sensing bulb placement — an improperly mounted sensing bulb can often result in the txv hunting.

Too far open is also called “overfeeding” and it means that boiling refrigerant is being fed too far through the evaporator coil, and this would show up in low superheat.
