8.5 Compressor Inspection
(1) Compressor motor inspection
• Measure resistance across the terminals of the
compressor motor.
• If the measured resistance is not equal to the
standard values listed above, replace the compressor. The compressor has an external
overload relay. The overload relay should be operational if the above resistance is obtained
under normal temperature. For overload relay specifications, refer to the chart below.
(2) Overload relay inspection
• Check for continuity across two terminals of the
overload relay. At normal temperature, there
should be continuity across the terminals.
• If there is no continuity across the terminals,
replace the overload relay.

8.6 Fan Motor Inspection
• Measure resistance across the terminals of the
fan motor.
• If the measured resistance is not equal to the
standard values listed above, replace the fan
motor.
