Is This the Right Part?

✅ Cross Reference Information

Common Symptoms

• Frost or ice buildup on the evaporator coil
• Refrigerator or freezer section too warm
• Freezer not defrosting properly
• Airflow restriction caused by accumulated frost
• Defrost cycle not terminating correctly

Check Before Replacing

• Disconnect refrigerator power before accessing the assembly.
• Visually inspect the evaporator area and sensor harness for frost, physical damage, or loose connectors.
• With the assembly disconnected and using the appliance service documentation, check sensor resistance at a known temperature; compare the reading with the specified temperature-resistance values.
• Check the assembly fuse for continuity with power disconnected; an open fuse indicates a fault in the assembly, but does not by itself establish the root cause of the defrost problem.
• Confirm that the connector and wiring match the appliance wiring diagram before replacing the part.

Installation Notes

• Disconnect electrical power before servicing the refrigerator.
• Access commonly requires removal of freezer components and the evaporator cover; the exact access procedure varies by model.
• Disconnect the wiring connector carefully and preserve the original wire routing and sensor placement.
• Install the replacement assembly in the same position and reconnect it securely before reinstalling removed panels and components.
• Follow the model-specific service manual because appliance construction and connector arrangements vary.
