  1. Disconnect refrigerator from power
  2. Access the temperature sensor/thermistor for the refrigerator compartment
  3. Measure resistance of sensor to confirm short/open circuit relative to specification
  4. Check wiring harness and connectors for continuity and corrosion
  5. Replace the faulty temperature sensor and/or repair wiring as needed; verify operation
  6. Test refrigeration system and confirm error clears

Parts needed: Temperature sensor (thermistor), Wiring harness and connectors
