Failed ice chute
solenoid
Listen for auger motor operation while the switch is
pressed. If the auger motor is operating, then check
that the ice chute door is not mechanically stuck
closed. If there is not a mechanical problem, then
check for line voltage across the solenoid during
operation. If line voltage is present then replace the
solenoid. Otherwise, verify that there is line voltage on
J2 of the power board pins 1 to 9 during operation.
If line voltage is present, then
repair/replace the wiring to the solenoid.
Otherwise check for 5.0 VDC present at
the power board J1 pins 4 to 10. If 5.0
VDC is present, then replace the power
board. If no voltage is present, then
check the same pins on J1 of the control
board. If 5 VDC is present on the control
board then repair/replace the harness,
else replace the control board.
Auger motor
continuously
cycling on and off
when dispenser
button is not
being pressed.
Motor is cycling
on thermal
overload. Switch
is stuck closed or
mechanical
obstruction is
forcing switch
closure.
Set up meter to read 5 VDC. Check across pins 1 and
4 of the dispenser connector.
Without pressing dispenser switch the voltage should
be 5 VDC.
If the reading is 0 VDC, then the
dispenser switch is closed in error.
Troubleshoot the pad assembly and
switch. Repair or replace as necessary.
If voltage measures ok, then remove
probe from pin 1 and check voltage at J1
pins 4 and 5. If 5 VDC is read at either
point, then replace the control board
otherwise replace the power board.
Water valve stuck
open.
Open the freezer door.
If the water flow does not stop, then
replace the water valve.
Otherwise go to the frame below.
Water flowing
continuously
without pressing
a dispensing
button.
Dispensing
switch stuck
closed
Set up meter to read 5 VDC. Check across pins 1 to 4
and 2 to 4 of the dispenser connector.
Without pressing dispenser switch the voltage should
be 5 VDC.
If either reading is 0 VDC, then the switch
is closed in error. Troubleshoot the pad
assembly or Front Fill button and switch.
Repair or replace as necessary.
If voltage measures ok, then remove
probe from pin 1 and check voltage at J1
pin 7. If 5 VDC is read, then replace the
control board otherwise replace the power
board.
Cannot turn off
the door alarm
and the display
says one of the
doors is open all
the time.
Failed or
improperly
adjusted door or
the door switch.
Open the door signaled as being open. Manually
close the door switch.
Does the alarm stop? If so, then check the door
adjustment. Otherwise go to the next frame below.
Adjust door, door switch or replace the
door switch as needed to turn off the
alarm.
Failed wiring
harness or
connection to the
power board.
Unplug the refrigerator. Remove the façade from the
door. Disconnect the freezer door harness from the
power board.
To test the freezer door connections, attach the
voltmeter probes to J2, VT wire (pin 4) and WH (pin
10) on the harness. Set up the meter for line voltage
AC type. Place the meter so that it is not held or
touching any metal.
Power up the refrigerator. There must be line voltage
across the meter when the door is closed and <15
VAC when the door is open.
To test the refrigerator door connections, use the
same procedure as for the freezer door test above
except attach the voltmeter probes to J2, RD/WH wire
(pin 3) and WH (pin 10) on the harness.
If the voltage readings are incorrect, then
power down the refrigerator and replace
the power board.
Otherwise power down the refrigerator.
Attach the control board to the unit. Move
the probes to J1 pins 10 and 2 on the
control board. Repeat the last test. If the
voltage readings are incorrect, then
replace the jumper harness, otherwise
replace the control board.
