8.10 Inspection of Wiring Connection

• Refer to the Wiring Diagrams on page 19 and check for connection of each wire.

8.11 Inspection of Thermistor

• Using an Ohm-meter, check the resistance value across the 2-pin connector. At normal

temperature (77 °F (25 °C)) either thermistor (room or freeze) should measure approximately

10K ohm.

8.12 Inspection

• In most cases, the probable cause for insufficient cooling is a clogged system, leakage or an

incorrect amount of refrigerant. In such cases, inspect the system according to the following

procedure.

(1) Inspection of clogged system

• Check the component parts of the refrigerant system, including piping, that could be clogged

with refrigerant. If clogged with refrigerant, only the clogged part is frosted partially. In such a

case, change the part in question.

(2) Inspection of refrigerant leak

• Carefully check all connections, and each component for leaks whenever the refrigerant system

is installed or repaired. Use an electronic gas leak tester to inspect the system.

(3) Insufficient refrigerant

• In case the unit is judged to be deficient in cooling capacity, Make sure to perform the inspections

in 56. 9.1 (1) and 56. 9.1 (2) to confirm the cause of trouble. Then, charge the system with

refrigerant to the specified amount.
