Problem: Freezer temperature sensor fault; thermistor open circuit, shorted, or out of operational range

How to Fix Refrigerator Error

1. Unplug refrigerator from electrical power or switch off dedicated circuit breaker.
2. Remove freezer interior panels to access temperature sensor (typically mounted on evaporator cover or freezer wall).
3. Disconnect wiring harness from sensor connector. Note routing path before removal.
4. Measure resistance across sensor terminals with multimeter at current freezer temperature. Compare to service manual chart (e.g., at 0°F/-18°C should be ~17kΩ).
5. If reading is infinite (open), zero (shorted), or deviates >15% from chart: remove mounting clip or screw securing sensor.
6. Gently extract sensor from mounting well without damaging threads or surrounding components.
7. Clean mounting well thoroughly with isopropyl alcohol and lint-free cloth.
8. Apply thin layer of thermal conductive paste to sensing tip of new sensor.
9. Install replacement temperature sensor using OEM part DA32-10104R. Secure in mounting clip or with screw tightened to 3 in-lbs.
10. Route wiring away from sharp edges and moving parts. Reconnect harness until audible click. Reassemble interior panels. Restore power and monitor freezer temperature display for 2 hours to confirm accurate readings.
