Ice ‘N Water Systems<br />
Symptom Possible<br />
Cause<br />
Crushed ice Failed<br />
starts to dispense dispenser<br />
as soon as switch (failed<br />
Crushed mode is<br />
selected without<br />
short)<br />
pressing the<br />
dispenser switch.<br />
Failed PCB<br />
Cubed LED is<br />
illuminated but<br />
does not<br />
dispense cubed<br />
ice when<br />
dispenser switch<br />
is pressed.<br />
Cubed ice starts<br />
to dispense as<br />
soon as Cubed<br />
mode is selected<br />
without pressing<br />
the dispenser<br />
switch<br />
1. Auger motor<br />
operates in<br />
Cubed or<br />
Crushed mode<br />
but ice chute door<br />
never opens.<br />
2. Auger motor<br />
operates in<br />
Cubed or<br />
Crushed mode<br />
but ice chute door<br />
never closes.<br />
No LED lit, auger<br />
motor operates<br />
only in Cubed<br />
mode, and ice<br />
chute door never<br />
opens or never<br />
closes.<br />
No LED lit, auger<br />
motor operates<br />
only in Cubed<br />
mode, and<br />
dispenser light<br />
never switches on<br />
or never switches<br />
off.<br />
Neither Water,<br />
Crushed or<br />
Cubed LED will<br />
not illuminate but<br />
Water, Crushed<br />
or Cubed mode<br />
operates properly<br />
when selected.<br />
Failed<br />

No continuity<br />
Failed auger<br />

Failed PCB<br />
Test Procedure Repair<br />
Disconnect power. Remove both leads from the<br />
switch and measure resistance across switch<br />
terminals. Resistance should read less than 1 Ω<br />
in this position and higher than 10 MΩ when<br />
switch is open.<br />
With PCB powered, measure voltage on pin 4<br />
(BU wire) of 9-pin connector. Voltage should<br />
read 0 VAC.<br />
Disconnect power. Remove both leads from the<br />
switch and measure resistance across switch<br />
terminals. Resistance should read less than 1 Ω<br />
in this position and higher than 10 MΩ when<br />
switch is open.<br />
Disconnect power. Remove the cover of freezer<br />
door hinge located on top of the unit and<br />
disconnect the connectors. Check OR wire (pin 3<br />
of 9-pin connector) for continuity.<br />
With PCB powered, press the dispenser switch.<br />
Measure voltage on pin 3 (OR wire) of 9-pin<br />
connector. Voltage should read 120VAC.<br />
Disconnect power. Remove both leads from the<br />
switch and measure resistance across switch<br />
terminals. Resistance should read higher than 10<br />
MΩ when switch is open and less than 1 Ω when<br />
switch is closed.<br />
With PCB powered, measure voltage on pin 3<br />
(OR wire) of 9-pin connector. Voltage should<br />
read 0 VAC.<br />
Failed solenoid Disconnect power. Remove both leads from the<br />
solenoid and measure the resistance across<br />
solenoid terminals. Resistance should read –<br />
101.2 ohms ±10%<br />
Failed PCB Measure voltage on pin 1 (GY wire) of 9-pin<br />
connector. Voltage should read approximately<br />
55VDC when ice chute door is open (solenoid<br />
energized) or 0 VDC when closed (solenoid not<br />
energized).<br />
