Liquid Level Control Test Procedure
1.Disconnect the dispenser from the power source.
2.Check the voltage across terminals 3 & 4 of the electronic control assembly with a voltmeter. Con- nect the dispenser to the power source. The indi- cation must be:
a.) 100 to 120 volts ac for 100 to 120 volt models or
b.) 200 to 240 volts ac for 200 to 240 volt models.
3.Disconnect the dispenser from the power source. If voltage was present as described, proceed to #4. If voltage was not present as described, refer to the Wiring Diagrams and check the dispenser wir- ing harness.
4.Remove the pink wire from terminal 5 of the elec-

tronic control assembly.
5.Check the voltage across terminals 1 & 4 of the electronic control assembly with a voltmeter. Con- nect the dispenser to the power source. The indi- cation must be:
a.) 100 to 120 volts ac for 100 to 120 voltmodels or
b.) 200 to 240 volts ac for 200 to 240 volt models after a delay of approximately 5 seconds.
6.Disconnect the dispenser from the power source.
If voltage was present as described, the liquid level control of the system is operating properly, proceed to #7.
If voltage was not present as described, replace the electronic control assembly and the temperature sen- sor in the tank lid.
NOTE - Each electronic control assembly is calibrated to a temperature sensor. Both components MUST be replaced as a set.
