Location:
The fan is located inside the dispenser chassis just
in front of the condenser.
Test Procedures:
1. Disconnect the dispenser from the power source.
2. Disconnect the yellow and white/black wires from
the main harness to the fan leads.
3. With a voltmeter, check the voltage across the yellow
and the white/black wires and the “ON/OFF” switch in
the “ON” position. Connect the dispenser to the
power source. The indication must be:
a) 120 volts ac for 120 volt models.
b) 230 volts ac for 230 volt models.
4. Disconnect the dispenser from the power source.
If voltage is present as described, replace the fan.
If voltage is not present as described, refer to
Wiring
Diagram and check the dispenser wiring harness.
