FIG. 34 COLD WATER SOLENOID VALVE |
Location: |
The cold water solenoid valve is located on the left side of the dispenser base just behind the com- ponent bracket.
Test Procedures:
1.Disconnect the dispenser from the power source.
2.Disconnect the white and blue wires from the solenoid valve. With the cold jumper plug in- stalled press the left dispense switch on front of the door.
3.Check the voltage across the white and blue wires with a voltmeter. Connect the dispenser to the power source. The indication must be 120 volts ac for two wire 120 volt models, three wire 120/ 208 and 120/240 volt models.
4.Disconnect the dispenser from the power source.
If voltage is present as described, proceed to #5
If voltage is not present as described, refer to wiring diagram and check dispenser wiring harness.
5.Check for continuity across the solenoid valve coil terminals.
If continuity is present as described, reconnect the white and blue wires to the solenoid.
If continuity is not present as described, replace the solenoid valve.
6.Check the solenoid valve for coil action. Connect the dispenser to the power source. With the cold jumper plug installed press the left dispense switch and listen carefully in the vicinity of the solenoid valve for a “clicking” sound as the magnet attracts.
7.Disconnect the dispenser from the power source.
If the sound is heard as described and water will not pass through the solenoid valve, there may be a block- age in the water line before the solenoid valve or, the solenoid valve may require inspection for wear, and removal of waterborne particles.
If the sound is not heard as described, replace the solenoid valve.
Removal and Replacement:
1.Loosen the two screws securing the component bracket to the dispenser base. Lift the component bracket off of the base and move to the right.
2.Remove the white and blue from the solenoid valve.
3.
4.Disconnect the water lines to and from the sole- noid valve.
5.Loosen the two
6.Remove the two
7.Using two
8.Install the solenoid valve and bracket on the dis- penser base and tighten the two
9.Securely fasten the water lines to and from the solenoid valve.
10.Refer to Fig. 35 when reconnecting the wires.
