Common Symptoms
- Refrigerator cooling operation is irregular.
- Defrost cycling is irregular, which can contribute to frost accumulation.
- Temperature control is inconsistent.
Check Before Replacing
- Verify the refrigerator has power and that its temperature controls are set correctly before attributing a cooling issue to the board.
- If service access is appropriate, unplug the refrigerator and visually check the board-area wire connectors for loose seating, damage, or corrosion; do not probe energized circuitry.
- Compare observed cooling and defrost behavior with the model's normal operation; other components and wiring can cause similar symptoms.
Pro Tip
Because this is an electronic control board, treat cooling and defrost symptoms as system-level symptoms: confirm power, settings, wiring connections, and other related components before replacing the board.
