6.6 Inspection of Compressor Motor
• Measure resistance across the terminals of
the compressor motor. (All terminals must be
disconnected from the unit.)
CAUTION
• To disconnect from the terminals, pull out the
plastic connector cap from the compressor. Do
not pull the electrical wires.
• To reconnect to the terminals, insert the plastic
connector cap straight into the terminals. Do not
apply excessive force when inserting the plastic
connector cap into the terminals. Maximum
clearance space between compressor and
plastic connector is 0.08 in (2 mm).
• Resistance value between terminals at 77 °F
(25 °C)
- R-C Approx. 1.23 ohm
- C-S Approx. 1.47 ohm
- S-R Approx. 2.7 ohm
• If the measured resistance is not equal to these
standard values, replace the compressor. The
overload relay is internal to the compressor.
6.7 Thermistor Inspection
• Use an ohmmeter to check the resistance
across the 2-pin connector at normal
temperature (77 °F (25 °C)).
