Symptom Possible

Cause

Test Procedure Repair

Switch failure in

freezer door.

With 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.

With unit powered, measure voltage between pin

9 (WH 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

Water, Crushed

or Cubed mode.

Failed light bulb

or PCB.

With 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 MΩ when

switch is open.

Replace switch.

Dispenser light is

on without

pressing the

dispenser switch

in Water,

Crushed or

Cubed mode.

Failed PCB

With 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.

Water LED is

illuminated but

does not

dispense water

when dispenser

switch is pressed

Failed water

valve or PCB.

With 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.

Water starts to

dispense as soon

as Water 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 MΩ when

switch is open.

Replace switch.

Failed PCB

With 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.

With 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.
