Repair Section 46
8.11 Refrigeration System Inspection
• In most cases, the causes for insufficient cooling is a clog in the system, a leakage, or an
incorrect amount of refrigerant. In such cases, inspect the system according to the
following procedure.
(1) Clogged refrigeration system
• Check the component parts of the refrigeration system, including piping, that could be clogged with
refrigerant. If clogged with refrigerant, only the clogged part is partially frosted. If this occurs,
change the part in question (see page 63).
(2) Refrigerant leak
• Carefully check all connections, and each component for leaks whenever the refrigeration
system is installed or repaired. Use an electronic gas leak tester to inspect the system.
(See page 68).
(3) Insufficient refrigerant
• When the unit is not producing sufficient cooling, follow the troubleshooting chart on page 38 to
confirm the cause of the problem. Then, charge the system with the refrigerant to the specified
amount as indicated on page 70.
