Problem: Freezer compartment temperature sensor fault – out of range reading

How to Fix Refrigerator Error
1. Unplug refrigerator and remove all frozen food from freezer compartment.
2. Locate temperature sensor behind rear wall panel in freezer section (typically near evaporator coils).
3. Remove shelves/baskets and unscrew rear wall panel to access evaporator assembly.
4. Disconnect sensor connector (usually white 2-wire connector near evaporator coils).
5. Measure resistance with multimeter at freezer temperature (0°F/-18°C): should read approximately 25kΩ.
6. Warm sensor in hand to 77°F/25°C – resistance should decrease to approximately 5kΩ.
7. If resistance is infinite (open circuit) or zero (shorted), replace sensor WPW
8. Inspect sensor mounting clip – must be securely attached to evaporator tubing (loose mounting causes False readings).
9. Check wiring harness for damage near evaporator fan where vibration occurs.
10. After replacement, verify freezer temperature stabilizes at 0°F within 4 hours of operation.
