Capillary Tube Assy (Cool Only Units) - Friedrich Kuhl KCS12B10A Service Manual

Capillary Tube Assy (Cool Only Units)

Test the Capillary Tube and Check Valve Assy
1. Check the capillary tube temperature by hand where the refrigerant enters the capillary tube. A partial restriction of the capillary
tube will be indicated by frost or freezing in that area.
2. If the capillary tube is fully restricted, then pressure will increase and pressure switch will open if installed. If no pressure switch
is installed, the unit will shut down due to the compressor overload opening. High discharge temperature will be present at the
compressor.
