The air conditioning orifice tube is a component that controls the refrigerant flow by turning the compressor on and off.
AC orifice tube significanceThe orifice tube limits the flow of the hot liquid refrigerant, letting it spray out the other side at a lower gas temperature. The low-temperature gas cools the evaporator, so the evaporator gets rid of the heat from the vehicle instantly. The orifice tube also has the task of filtering the refrigerant for any corrosive material that can travel via the air conditioner. The filter keeps the A/C system from damaging quickly, but the orifice tube will have to be replaced to maintain a clean environment.
Common issues with a faulty AC orifice tubeA faulty AC orifice tube can lead to clogging, frost traveling through the vents, or the AC compressor may run nonstop.
