Ice ‘N Water Systems

Symptom Possible

Cause

Test Procedure Repair

Failed Main

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

this position and higher than 10 MΩ 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 4

of 10-pin connector) for continuity.

Repair open

connection.

Cubed LED is illuminated

but does not dispense

cubed ice when Main

dispenser switch is

pressed.

Failed auger

motor or PCB.

With PCB powered, press the Main dispenser

switch. Measure voltage on pin 4 (OR wire) of 10-

pin connector. Voltage should read 120VAC.

Replace auger motor if

voltage reads 120VAC.

If not, replace PCB.

Failed Main

dispenser

switch (failed

short)

Disconnect power. Remove both leads from the

switch and measure resistance across switch

terminals. Resistance should read higher than 10

MΩ 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 Main

dispenser switch

Failed PCB

With PCB powered, measure voltage on pin 4

(OR wire) of 10-pin connector. Voltage should

read 0 VAC.

Replace PCB.

Dispenser operates

continuously even when

Dispenser Lock mode is

activated.

Failed PCB With PCB powered, measure voltage on pin 5 (BK

wire) of 10-pin connector. Voltage should read 0

VAC.

Replace PCB

Auto Light mode does not

operate.

Failed PCB With PCB powered and Auto Light activated,

cover the light sensor. Measure voltage on pin 2

(BR wire) of 10-pin connector. Voltage should

read 1/2 the AC power supply (120 VAC).

Replace PCB.

Ice or Water dispenser

mechanism runs

continuously.

Failed PCB With PCB powered, measure voltage on pin 5 (BK

wire) of 10-pin connector. Voltage should read 0

VAC.

Replace PCB.

Filter Status LED never

changes to red.

Failed PCB Verify with the user if unit has been unplugged for

a long period.

Demonstrate reset operation to customer.

Replace water filter and

reset Filter Status.

Replace PCB if problem

continues. Customer

education.

Failed solenoid Disconnect power. Remove both leads from the

solenoid and measure the resistance across

solenoid terminals. Resistance should read

101.2 ± 10%.

Replace solenoid.

1. Auger motor operates in

Cubed or Crushed mode

but ice door chute never

opens.

2. Auger motor operates in

Cubed or Crushed mode

but ice door chute never

closes.

Failed PCB Measure voltage on pin 1 (GY wire) of 10-pin

connector. Voltage should read approximately

55VDC when ice chute door is open (solenoid

energized) or 0VDC when closed (solenoid not

energized).

Replace PCB.

No LED lit, Water

dispenser operates, auger

motor operates only in

Cubed mode and ice chute

door does not open or

remains open.

Failed PCB

Replace PCB

No LED lit, Water

dispenser operates, auger

motor operates only in

Cubed mode and dispenser

light is on continuously.

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
