Ice and Water Dispense Troubleshooting Guide
General Information
1. During normal operation, certain components can fail
independently with no cascading effect to other ice and
water related components. These components are listed
below:
a. Water Valve
b. Auger Motor
c. Cube/crush Solenoid
2. During normal operation, other components fail with a
cascading effect. These components are listed below
with the related disabled components:
a. Fresh Food Door Switch – disables auger motor, cube/
crush solenoid, ice chute door solenoid
b. Paddle Microswitch – disables water valve, auger
motor, cube/crush solenoid, ice chute door solenoid,
automatic led illumination
c. Ice chute door solenoid – disables auger
motor, cube/crush solenoid
d. Ice chute door microswitch – diables Auger
Motor, cube/crush solenoid
3. During normal operation, the dispenser pocket will be
lit by a pair of LEDs on the ice and water module. The
LEDs can be set to be on 100% of the time or on only
when the paddle is pressed for ice or water.
Verify that the LEDs function properly prior to entering
service mode below.

3.
Press fresh food (^) to advance thru the menu
options; press 'power on-off' to initiate function
4.
Perform the following tests:
8 – Water Valve
10 – Auger Motor
10 – Auger Motor Switch
