Is This the Right Part?

✅ Cross Reference Information

Common Symptoms

• Erratic or inadequate cooling
• Cooling that does not maintain the selected temperature
• Possible defrost-timing or defrost-operation problems
• Unresponsive refrigerator controls or display

Check Before Replacing

• Confirm the refrigerator has power and that other appliance functions are operating before suspecting the control board.
• Check whether the symptom is limited to cooling/defrost control or also involves separate components such as fans, sensors, compressor, or door controls.
• With power disconnected, visually inspect the board area and wiring connectors for loose seating, visible damage, or moisture; do not handle energized circuitry.
• Verify the refrigerator model and the number printed on the existing board before ordering, because similar-looking boards may differ by model.
• If testing requires live-voltage measurements or sealed-system diagnosis, use a qualified appliance technician.
