Condenser Fan: Testing and Inspection

1. INSPECT CONDENSER FAN OPERATION.
Inspect the fan operation at these conditions, as shown in the chart.
Test conditions:
- Start Engine.
- Blower speed control switch position "HI".
- Temperature control dial at "COOL" position.
- Set on manifold gauge set.
- A/C switch ON.




If operation is not as specified, proceed to the next inspection.




2. INSPECT CONDENSER FAN MOTOR OPERATION.
a. Disconnect the fan connector.
b. Connect battery and ammeter to fan connector, as shown in the illustration.
c. Check that the fan rotates smoothly, and then check the reading on the ammeter.
Specified amperage:
Marking 1 (80 W): 6.5 ± 1.0 A at 25 °C (77 °F)
Marking 2 (120 W): 9.8 ± 1.0 A at 25 °C (77 °F)

If operation is not as specified, replace the fan motor. If operation is as specified, check the pressure switch, cooling fan relays and water temp. switch.
