Where is the orifice tube located?

Expansion (Orifice) Tube Replacement The expansion (orifice) tube is located at the condenser to evaporator tube connection in the condenser tube. Important: When you replace an expansion (orifice) tube, compare the design of the orifice tube to the design of the replacement part for the correct selection. The different styles of orifice tubes are not interchangeable. Recover the refrigerant. Remove the upper filler panel. Remove the bolt holding the evaporator hose assembly to the condenser. Remove the evaporator tube block fitting nut. Remove the evaporator tube from the condenser. Important: Cap or tape the open end of the evaporator tube immediately to prevent contamination. Remove and discard the O-ring seal. Using needle nose pliers, CAREFULLY grasp the edge of the expansion (orifice) tube without touching the filter screen and pull to remove the tube; cap or tape the evaporator tube to prevent contamination. Use the following procedure in order to remove a restricted or plugged expansion (orifice) tube: 8.1. Remove as much as possible of the impacted residue. 8.2. Use a heat gun in order to apply heat to the expansion (orifice) tube. Apply the heat approximately 7 mm (1/4 in) from the dimples on the inlet pipe. 8.3. While applying heat, use needle-nosed pliers in order to grip the orifice tube. Use a turning motion along with a push-pull motion. This will loosen the impacted orifice tube and remove the tube. 8.4. Swab the inside of the evaporator inlet line to clean any contamination from the line.
