    Problem: Power converter failure on main control board

    How to Fix Refrigerator Error

    1. Unplug refrigerator and remove rear access panel at top of cabinet.
    2. Locate main control board and inspect for burnt components near power input section.

    4. Verify 120V AC input terminals show proper voltage when plugged in (use multimeter carefully).
    5. Measure DC output voltages at test points: 5V DC for logic circuits, 12V DC for displays/sensors.
    6. If DC voltages are missing or unstable (<
    7. 5V or >
    8. 5V on 5V rail), power converter hasfailed.
    9. Inspect board for cracked solder joints around transformer and large capacitors (reflow if found).
    10. If power converter components test faulty or voltages are unstable, replace entire main control board W
    11. After replacement, verify all displays light properly and sensors report accurate readings.
    12. Monitor DC voltages during compressor startup to ensure regulator can handle inrush current.

    Problem: Refrigerator compartment fan failure – air circulation fan not operating

    How to Fix Refrigerator Error

    1. Unplug refrigerator and remove all food from fresh food compartment.
    2. Locate evaporator fan assembly (typically behind rear wall panel in refrigerator section on French door models).
