What Happens When Txv Is Stuck Open. Just an update, it was a bad compressor. Here you can experience both starving and flooding symptoms, but also load problems, varying pressure inside the device, and inappropriate amounts of refrigerant into the evaporator.

To a technician in a hurry, it could look like the txv is malfunctioning, but it isn't. A stuck open txv will flood and freeze the evaporator core, possibly damaging the compressor with incompressible liquid. A txv can overfeed from restricted air flow, return air blocked, dirty evaporator coil, dirty air filter, or a bad indoor fan.
The Valve Pin Restricts The Flow Of The Liquid Refrigerant.
You also need to trust the science of a/c. Fan running drops liquid condenser temp and pressure remove and heat the txv bulb while watching pressures. Containment or particulates getting stuck in the txv.
Some Txvs Have An Inlet Strainer.
Afterwards, as the pressure increases it pushes down on the diaphragm and this pushes down on the pin. Here is a closer view of the txv in operation. If there isn't enough pressure in that suction line leading up to the diaphragm, the valve either won't open enough, or may not open at all.
This Would Show Up In Low Superheat.
You have a package unit, but bad txv on indoor coil will stop liquid flow. A stuck closed txv will leave an evaporator starved of refrigerant and the compressor deprived of its lubricating oil. A restricted metering device — thermostatic expansion valve or txv — can cause a number of symptoms in a system.
At This Point It May Be Better To Recover Freon And Weigh It Back In To Make Sure You Are Charged Correctly Then Go From There.
A txv can overfeed from restricted air flow, return air blocked, dirty evaporator coil, dirty air filter, or a bad indoor fan. To a technician in a hurry, it could look like the txv is malfunctioning, but it isn't. The txv or thermostatic expansion valve is preferred over other refrigeration metering devices because it only allows a specified amount of refrigerant to flow based on demand.
Pushing Down The Stopper Increases The Refrigerant Flow.
What causes a txv to go bad? Any type of refrigeration metering device creates a pressure drop in the refrigerant and with a pressure drop of the refrigerant a temperature drop also occurs. The spring is also a.
