Symptom Possible
Cause
Test Procedure
Repair
Switch failure in
freezer door.
W ith unit powered, open freezer door. Press
freezer door switch in. If freezer light does not
turn off, switch is defective.
Replace switch.
Incorrect
harness wiring.
Verify wire color on 9-pin connector. Refer to
Table A.
Correct wiring.
No LED lit
No power to
the PCB.
W ith unit powered, measure voltage between pin
9 (W H wire) and pin 7 (VT wire) of 9-pin
connector. Meter should read 120VAC.
Replace PCB if meter
reads 120VAC.
No continuity.
Disconnect power. Measure continuity between
pin 2 (BR wire) of 9-pin connector and dispenser
lamp terminal.
Repair open connection.
No dispenser
light when
dispenser switch
is pressed in
W ater, Crushed
or Cubed mode.
Failed light bulb
or PCB.
W ith unit powered, press the dispenser switch.
Measure voltage on pin 2 (BR wire) of 9-pin
connector. Voltage should read 120VAC.
Replace dispenser light
bulb. If not, replace PCB.
Failed
dispenser
switch (failed
short)
Disconnect power. Remove both leads from the
switch and measure resistance across switch
terminals. Resistance should read less than 1
Ω
in this position and higher than 10 M
Ω
when
switch is open.
Replace switch.
Dispenser light is
on without
pressing the
dispenser switch
in W ater,
Crushed or
Cubed mode.
Failed PCB
W ith unit powered, measure voltage on pin 2
(BR wire) of 9-pin connector. Voltage should
read 0VAC
Replace PCB.
Failed
dispenser
switch (failed
open)
Disconnect power. Remove both leads from the
switch and measure resistance across switch
terminals. Resistance should read less than 1
Ω
in this position and higher than 10 M
Ω
when
switch is open.
Replace switch.
No continuity
Disconnect power. Remove the cover of freezer
door hinge located on top of the unit and
disconnect the connectors. Check YL wire (pin 6
of 9-pin connector) for continuity.
Repair open connection.
W ater LED is
illuminated but
does not
dispense water
when dispenser
switch is pressed
Failed water
valve or PCB.
W ith PCB powered, press dispenser switch.
Measure voltage on pin 6 (YL wire) of 9-pin
connector. Voltage should read 120VAC.
Replace water valve if
voltage reads 120VAC. If
not, replace PCB.
W ater starts to
dispense as soon
as W ater mode is
selected without
pressing the
dispenser switch
Failed
dispenser
switch (failed
short)
Disconnect power. Remove both leads from the
switch and measure resistance across switch
terminals. Resistance should read less than 1
Ω
in this position and higher than 10 M
Ω
when
switch is open.
Replace switch.
Failed PCB
W ith PCB powered, measure voltage on pin 6
(YL wire) of 9-pin connector. Voltage should
read 0 VAC.
Replace PCB.
Failed
dispenser
switch (failed
open)
Disconnect power. Remove both leads from the
switch and measure resistance across switch
terminals. Resistance should read less than 1
Ω
in this position and higher than 10 M
Ω
when
switch is open.
Replace switch.
No continuity
Disconnect power. Remove the cover of freezer
door hinge located on top of the unit and
disconnect the connectors. Check BU wire (pin 4
of 9-pin connector) for continuity.
Repair open connection.
Crushed LED is
illuminated but
does not
dispense crushed
ice when
dispenser switch
is pressed.
Failed auger
motor or PCB.
W ith PCB powered, press dispenser switch.
Measure voltage on pin 4 (BU wire) of 9-pin
connector. Voltage should read 120VAC.
Replace auger motor if
voltage reads 120VAC. If
not, replace PCB.
