    Problem: Water valve circuit fault – solenoid not activating or drawing incorrect current

    How to Fix Refrigerator Error

    1. Unplug refrigerator and turn off household water supply to unit.
    2. Remove rear access panel to access water inlet valve assembly (typically near bottom rear).
    3. Locate dual water valve assembly with separate solenoids for dispenser and ice maker.
    4. Disconnect wiring harness from valve assembly.
    5. Measure resistance across each solenoid coil (should read 300-500 ohms).
    6. If resistance is infinite (open circuit) or zero (shorted), solenoid has failed.
    7. Verify 120V AC reaches solenoid connector during dispenser activation or ice maker harvest cycle.
    8. Inspect valve body for mineral buildup restricting water flow (remove inlet screen and clean).
    9. Check water supply pressure – must be minimum 20 PSI for proper valve operation.
    10. If solenoid resistance is out of range or valve doesn’t open with power applied, replace water inlet valve assembly WPW

    Problem: Freezer evaporator fan speed fault – fan not reaching required RPM

    How to Fix Refrigerator Error

    1. Unplug refrigerator and remove rear wall panel in freezer compartment.
    2. Locate evaporator fan motor and inspect blade for ice buildup restricting rotation.
    3. Thaw ice accumulation using hair dryer on low setting (never chip ice with tools).
