Ice ‘N Water Systems
Symptom Possible
Cause Test Procedure Repair
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 Crushed ice
starts to dispense
as soon as
Crushed mode is
selected without
pressing the
dispenser switch.
Failed PCB
With PCB powered, measure voltage on pin 4
(BU 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 OR wire (pin 3
of 9 -pin connector) for continuity. Repair open connection.
Cubed LED is
illuminated but
does not
dispense cubed
ice when
dispenser switch
is pressed.
Failed auger
motor or PCB.
With PCB powered, press the dispenser switch.
Measure voltage on pin 3 (OR wire) of 9-pin
connector. Voltage should read 120VAC. Replace auger motor if
voltage reads 120VAC. If
not, replace PCB.
Failed
dispenser
switch (failed
short) Disconnect power. Remove both leads from the
switch and measure resistance acro ss switch
terminals. Resistance should read higher than 10
M
Ω
when switch is open and less than 1
Ω
when
switch is closed.
Replace switch Cubed ice starts
to dispense as
soon as Cubed
mode is selected
without pressing
the dispenser
switch
Failed PCB
With PCB powered, measure voltage on pin 3
(OR wire) of 9-pin connector. Voltage should
read 0 VAC. Replace PCB.
Failed solenoid Disconnect power. Remove both leads from the
solenoid and measure the resistance across
solenoid terminals.
Resistance should read –
101.2 ohms
±
10%
Replace solenoid. 1. Auger motor
operates in
Cubed or
Crushed mode
but ice chute door
never opens.
2. Auger motor
operates in
Cubed or
Crushed mode
but ice chute door
never closes.
Failed PCB Measure voltage on pin 1 (GY wire) of 9 -pin
connector. Voltage should read approximately
55VDC when ice chute door is open (solenoid
energized) or 0 VDC when closed (solenoid not
energized). Replace PCB.
No LED lit, auger
motor operates
only in Cubed
mode, and ice
chute door never
opens or never
closes. Failed PCB
Replace PCB
No LED lit, auger
motor operates
only in Cubed
mode, and
dispenser light
never switches on
or never switches
off. Failed PCB
Replace PCB
Neither Water,
Crushed or
Cubed LED will
not illuminate but
Water, Crushed
or Cubed mode
operates properly
when selected. Failed PCB Replace PCB
