Inspection of Compressor Motor
Inspection of Evaporator Fan Motor
Inspection of Condenser Fan Motor
21. Inspection of Condenser Fan Motor
Measure resistance across the terminals of the
fan motor.
Terminals (at 77˚F (25˚C))
J3-CF32
Approx. 9.0 Ω
J3-CF31 Approx. 8.83 Ω
CF31-CF32 Approx. 18 Ω
If the measured resistance does not approxi-
mately equal these standard values
± 10%,
replace the fan motor.
22. Inspection of Evaporator Fan Motor
Measure resistance across the terminals of the
fan motor.
Terminals (at 77˚F (25˚C))
CF11-CF22
Approx. 52.8 Ω
CF22-CF12 Approx. 50.7 Ω
If the measured resistance does not approxi-
mately equal these standard values
± 10%,
replace the fan motor.
23. Inspection of Compressor Motor
Measure resistance across the terminals of the
compressor motor.
Terminals (wire tag) at 77˚F (25˚C)
R-C (CC1-J4)
Approx. 1.0 Ω
C-S (J4-CC2) Approx. 2.2 Ω
S-R (CC2-CC1) Approx. 3.0 Ω
If the measured resistance does not approxi-
mately equal these standard values
± 10%,
replace the compressor.
24. Inspection of Wiring Connection
Refer to the Wiring Diagrams on page 45 and
check for connection of each wire.
25. Inspection of Thermistor
Using an Ohmeter, check the resistance value
across the 2-pin connector. At normal tempera-
ture (77˚F (25˚C)) either thermistor (room or freeze)
should measure approximately 10,000 or 10K
ohms.
