    Problem: Ice level sensor/optic eye failure in freezer door detecting ice bin full condition

    How to Fix Refrigerator Error

    1. UNPLUG refrigerator.
    2. Open freezer door and locate emitter/receiver sensors on opposite walls of ice chute (small red lenses).
    3. Clean lenses thoroughly with soft cloth and isopropyl alcohol.
    4. Check alignment – sensors must face each other directly without obstruction.
    5. Disconnect wiring harnesses and test continuity through sensor circuit.
    6. If sensors clean/aligned but error persists, replace both emitter and receiver assemblies (must replace as pair).
    7. Verify operation by placing hand between sensors – ice maker should stop when beam interrupted.

    How to Fix Kenmore Refrigerator Error 5Y EF

    Problem: Temperature sensor fault causing evaporator fan circuit error (253 series variant)

    How to Fix Refrigerator Error

    1. UNPLUG refrigerator.
    2. Test BOTH freezer and refrigerator thermistors for proper resistance values (consult tech sheet for model-specific values).

    4. Inspect all wire harness connections to board – unplug/replug each connector firmly.
    5. Check for burnt components or swollen capacitors on boards.
    6. Test continuity of communication wires between main board and display board (typically 4-6 conductor ribbon cable).
    7. If wiring intact but error persists, replace main control board first (more common failure point).
    8. If error remains after main board replacement, replace display/user interface board.

    How to Fix Kenmore Refrigerator Error F1

    Problem: Refrigerator compartment thermistor open circuit or out-of-range reading

    How to Fix Refrigerator Error

    1. UNPLUG refrigerator.
    2. Locate fresh food thermistor – typically behind rear wall panel near top air vent or in light assembly housing.
    3. Remove access panel and disconnect sensor connector.
    4. Measure resistance at room temperature (should be 5k-15k ohms depending on model).
    5. If reading OL (open) or wildly out of spec, replace thermistor.
    6. Route new sensor wire carefully avoiding door hinge pinch points.
    7. Secure sensor in original clip/location.
    8. Restore power and allow 4-6 hours for temperature stabilization before evaluating performance.

    How to Fix Kenmore Refrigerator Error F2

    Problem: Freezer compartment thermistor failure

    How to Fix Refrigerator Error

    1. UNPLUG unit.
    2. Remove evaporator cover panel inside freezer compartment.
    3. Locate freezer thermistor clipped to evaporator coil tubing (white probe with 2 wires).
    4. Disconnect connector and test resistance (5k-15k ohms at room temp).
    5. Replace if open/shorted or reading outside specification.
    6. IMPORTANT: Position new sensor in EXACT same location as original – even 1 inch difference causes temperature control issues.
    7. Secure with original clip or high-temp adhesive.
    8. Reassemble and verify freezer reaches 0°F within 4 hours of startup.

    How to Fix Kenmore Refrigerator Error F3

    Problem: Defrost system failure – heater or thermostat fault causing excessive frost buildup

    How to Fix Refrigerator Error

    1. UNPLUG refrigerator and initiate manual defrost (leave doors open 8-12 hours until all ice melts).
