DISPENSE SWITCH(S) - FMD-1 & FMD-2 (cont.)
Test Procedure:
1.Disconnect the dispenser from the power source.
2.Open the dispenser door and remove the bottom door cover.
3.Disconnect the wires from the door interconnect wiring harness to the dispense switch.
4.Check for voltage across the black wire and the red wire from the door interconnect wiring harness. Connect the dispenser to the power supply. The indication must be:
a)120 volts ac for two wire 120 volt models.
b)120 volts ac for three wire 120/208 volt or 120/ 240 volt models.
5.Disconnect the dispenser from the power source.
If voltage is present as described, proceed to #6.
If voltage is not present as described, refer to the wir- ing diagram and check the dispenser wiring harness.
6.Check for continuity across the terminals with the switch in the“ON” pressed position. Continuity must not be present when the switch is in the “OFF” released position.
If continuity is present as described, reconnect the connector to the door interconnect wiring harness, the switch is operating properly.
If continuity is not present as described, replace the switch.
1.Disconnect the dispenser from the power source.
2.Open the dispenser door and remove the bottom door cover.
3.Disconnect the wires from the door interconnect wiring harness to the dispense switch to be tested.
4.Check for voltage across the black and red/white wires for the right dispense switch or the black and red wires for the left dispense switch from the door interconnect wiring harness. Connect the dis- penser to the power supply. The indication must be:
a)120 volts ac for two wire 120 volt models.
b)120 volts ac for three wire 120/208 volt or 120/ 240 volt models.
5. Disconnect the dispenser from the power source.
If voltage is present as described, proceed to #6.
If voltage is not present as described, refer to the wir- ing diagram and check the dispenser wiring harness.
6.With a voltmeter, check the voltage across the black/white (+) and orange
If voltage is present as described, proceed to #7.
If voltage is not present as described, refer to the wiring diagram and check the dispenser wiring har- ness.
7.Check for continuity across the terminals (top right to top left; bottom right to bottom left) of the dispense switch with the switch in the “ON” posi- tion. Continuity must not present when the switch is in the “OFF” released position.
If continuity is present as described, reconnect the connector to the door interconnect wiring harness, the switch is operating properly.
If continuity is not present as described, replace the switch.
Removal and Replacement
1.Open the dispenser door.
2.Remove the five
3.Disconnect the wires on the dispense switch from the door interconnect wiring harness.
4.Compress the clips inside the door on the dis- pense switch and gently push the switch through the opening
5.Push the new switch into the opening and spread the clips to hold the switch in the door.
6.Reconnect the wires to the dispense switch from the door interconnect wiring harness.
7.Reinstall the door bottom cover using five
8.Refer to Fig. 14 when reconnecting wires.
