Test Procedure:
1. Disconnect the dispenser from the power source.
2. Remove the five screws attaching the dispenser
door cover to the door and move the door cover
to gain access to the switches.
3. With a voltmeter, check the voltage across the two
wires for each dispense switch. Connect the dis-
penser to the power source. The indication must
be +5 volts dc.
If voltage is present as described, proceed to #4.
If voltage is not present as described, refer to the Wiring
Diagrams and check the dispenser wiring harness.
4. Check for continuity across the terminals (top right

the “ON” position. Continuity must not be present
when the switch is in the “OFF” (released) posi-
tion.
If continuity is present as described, reconnect the door
wiring harness, the switch is operating properly.
If continuity is not present as described, replace the
switch.
