    How to Fix Whirlpool Refrigerator Error Flash Code 1-2

    Problem: Refrigerator sensor open circuit (1 flash pause 2 flashes on control board LED)

    How to Fix Refrigerator Error

    1. Unplug refrigerator and remove rear access panel at top of cabinet to access main control board.
    2. Locate diagnostic LED on control board (typically red LED near edge connector).
    3. Count flash pattern: 1 flash, pause, 2 flashes = refrigerator sensor fault.
    4. Remove interior panels to access refrigerator temperature sensor behind rear wall.
    5. Disconnect sensor connector and measure resistance at room temperature (77°F/25°C): should read 5kΩ ±5%.
    6. If resistance is infinite (open circuit), replace sensor WPW
    7. Inspect wiring harness between sensor and control board for broken wires near door hinge.
    8. Repair broken wires with waterproof heat-shrink connectors or replace entire harness section.
    9. After repair, restore power and verify LED stops flashing error code within 2 minutes.
    10. Monitor refrigerator temperature stabilization within 1 hour of repair.

    Problem: Main control board EEPROM failure (3 flashes pause 3 flashes on LED)

    How to Fix Refrigerator Error

    1. Unplug refrigerator for 10 minutes to fully discharge board capacitors.
    2. Remove rear access panel to access main control board.

    4. Check all wire harness connections for proper seating and corrosion – reseat firmly.
    5. Verify 120V AC power supply to board is stable (no voltage sags during compressor startup).
    6. If board appears physically intact but error persists after power cycle, EEPROM corruption has occurred.
    7. Main control board must be replaced – EEPROM cannot be reprogrammed in field service.
    8. Install new control board W11035831 and secure all mounting screws to prevent vibration damage.
    9. After installation, power on refrigerator and allow 24 hours for system to stabilize temperatures.
    10. Note: Power surges often cause this failure – recommend installing whole-house surge protector to prevent recurrence.
