4-17. EVAPORATOR FAN MOTOR AND HOUSING ASSEMBLY/Inspect, Service, Test, Repair,
Replace (Cont)
L O C A T I O N / I T E M
EVAPORATOR MOTOR
Test:
1. Using an ohmmeter or other continuity testing device check that no continuity exist
between all pins and the electrical connector P-3.
2. If continuity requirements are not met, replace connector P-3.
3. Using an ohmmeter or other continuity testing device, check continuity between
connector pins A-B, A-C and B-C, and between D-E, D-F and E-F.
4. If continuity requirements are not met repair or replace evaporator motor.
5. Using an ohmmeter or other continuity testing device, check that continuity exists
between pins A, B, C, D, E, and F and the motor housing (stator).
6. Using an ohmmeter or other continuity testing device, check that continuity does exist
between pin G and the motor housing (stator).
7. If continuity requirements are not met, repair or replace evaporator motor.
8. Using an ohmmeter or other continuity testing device, check continuity between all
terminals on thermal overload (high speed with blue/white wires).
9. Using an ohmmeter or other continuity testing device, check continuity between all
terminals on thermal overload (low speed with green/white wires).
10. If continuity requirements are not met, replace thermal overload.
