Symptom
Possible Cause
Test Procedure
Repair
Shorted water solenoid
switch.
Remove leads from switch and measure
resistance across switch terminals. Resistance
is greater than 1M
Ω
in open position and less
than 1
Ω
when actuator is pressed closed.
Replace water solenoid switch.
PCB failure.
If no LED’s turn on PCB is defective.
Replace PCB.
Water all the
time.
Water valve stuck open.
Remove power to the refrigerator. If water still
flows through the valve, valve is bad or there is
low water pressure.
Replace the water valve or correct
household water pressure.
Operational error: Lens
is dirty or covered with
contamination.
Make sure nothing covers or masks
photosensitive lens.
Clean lens area of control.
Night-light on all
the time. Cavity
light works
properly, comes
on when ice or
water actuated.
PCB: Defective photo-
sensor circuit.
If night-light is on all the time and procedure
above has been preformed, PCB is defective.
Replace PCB.
Cavity light all the
time. Ice and
water work OK.
Incorrect harness wiring.
Verify wire colors on 10-pin connector against
the wiring diagram.
Correct wiring and retest.
Filter LED never
changes to red.
Operational error: User
mistakenly resets filter
counter.
Demonstrate reset operation to customer.
Customer education.

WARNING
To avoid risk of electrical shock that can cause death or severe personal injury, disconnect unit from power before
servicing unless tests require power. Discharge capacitors through a 10,000-ohm resistor before handling. Wires
removed during disassembly must be replaced on correct terminals to ensure proper grounding and polarization.
