Is This the Right Part?

Common Symptoms

• Refrigerator does not cool or the freezer does not freeze properly
• Refrigerator section is warm while the freezer remains cold
• Defrost operation fails, causing frost or ice buildup
• Ice maker, water dispenser, or ice dispenser functions stop working
• Control panel communication, display, or alarm-related problems occur
• Refrigerator may not start or may run continuously

Check Before Replacing

• Confirm the refrigerator has power and that the wall outlet is properly supplying power before suspecting the board.
• Check the refrigerator wiring diagram and inspect accessible harness connectors for loose, damaged, or corroded connections.
• With power disconnected, visually inspect the board and its housing for obvious burn marks, damaged components, or signs of electrical damage.
• Check whether the reported symptom is isolated to a user interface, dispenser, ice-maker, compressor-inverter, sensor, or other component before replacing the main board.
• If qualified to perform electrical testing, verify the relevant supply or output voltage only according to the model-specific wiring diagram and safe service procedures.
