Test Procedure:

1.Disconnect the dispenser from the power source.

2.Open dispenser door and remove the bottom door cover.

3.Disconnect the wires from the door interconnect wiring harness to the digital touch control switch assembly.

4.With a voltmeter, and using pin 1 of the multi-pin connector of the door interconnect wiring harness as a reference (-), check for voltage at each of the other pins of the connector. Connect the dispenser to the power source. The indication must be +5 volts dc.

5.On dispensers with a hot water valve, with a volt- meter, and using pin 1 of the multi-pin connector of the door wiring harness as a reference (-), check for voltage at pin 13 (blue/red wire). Connect the dispenser to the power source. The indication must be approximately 37 volts dc.

6.Disconnect the dispenser from the power source.

If voltage is present as described, proceed to step 7. If voltage is not present as described, refer to the wiring diagram and check the dispenser wiring harness.

7.While pressing the appropriate switch, check for continuity across the following pins of the digital touch control switch assembly’s multi-pin connec- tor:

Note: Pin 1 of the connector is identified by an arrow embossed on the connector housing.
