FIG. 43 COLD WATER SOLENOID TERMINALS
P1215
SOLENOID VALVE (COLD WATER - OPTIONAL for
FMD-2,-3,-4,-5)
FIG. 42 COLD WATER SOLENOID VALVE
Location:
The cold water solenoid valve is located on the left
side of the dispenser base just behind the component
bracket.
Test Procedures:
1. Disconnect the dispenser from the power source.
2. With the “HOT/COLD” switch in the “COLD” (upper)
position press any left dispense switch on front of
the door.
3. With a voltmeter check the voltage across the white
and white/yellow wires at the solenoid terminals.
Connect the dispenser to the power source. The
indication must be:
a) 120 volts ac for two wire 120 volt models
b) 120 volts ac for three wire 120/208 or 120/240
volt models
c) 240 volts ac for two wire 240 volt models.
d) 230 volts ac for two wire 230 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. Disconnect the white and white/yellow wires from
the solenoid.
6. Check for continuity across the solenoid valve coil
terminals.
If continuity is present as described, reconnect the
white and white/yellow wires to the solenoid.
If continuity is not present as described, replace the
solenoid valve.
7. Check the solenoid valve for coil action. Connect the
dispenser to the power source. With “HOT/COLD”
switch in the “COLD” (upper) position press the left
dispense switch and listen carefully in the vicinity
of the solenoid valve for a “clicking” sound as the
coil magnet attracts.
8. 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 white/yellow wires from the
solenoid valve.
3. Turn off the water supply to the dispenser.
4. Disconnect the water lines to and from the solenoid
valve.
5. Loosen the two #8-32 screws and washers secur-
ing the solenoid mounting bracket to the base.
Remove solenoid bracket and solenoid valve as an
assembly.
6. Remove the two #10-32 screws and lockwash-
ers securing the solenoid valve to the solenoid
bracket.
7. Using two #10-32 screws and lockwashers install
new solenoid valve on solenoid mounting brack-
et.
8. Install the solenoid valve and bracket on the dis-
penser base and tighten the two #8-32 screws.
9. Securely fasten the water lines to and from the
solenoid valve.
10. Refer to schematic wiring diagrams when recon-
necting the wires.
