3Check the voltage across black wire and the white wire on the main harness. Connect the dispenser to power source. The indication must be:
a.120 volts ac for two wire 120 volt models.
b.120 volts for three wire 120/208 volt models and three wire 120/240 volt models.
4. Disconnect the dispenser from the power source.
If voltage is present as described reconnect the wires and proceed to #5.
If voltage is not present as described, refer to the wiring diagrams and check the main wiring harness.
5.Check the voltage between
If voltage is present as described the transformer is operating properly.
If voltage is not present as described, replace the transformer.
Removal and Replacement:
1.Loosen the three
2.Pull component bracket out the front of the dis-
penser far enough so the transformer can be disconnected from the main wiring harness.
