  4. Check for obvious signs of wiring damage near visible sensor locations (rear interior wall).

Technician Only Diagnose and replace temperature sensor or wiring

  1. Disconnect power to the refrigerator.
  2. Access the refrigerator compartment temperature sensor behind the interior panel.
  3. Inspect and test the resistance of the NTC sensor with a multimeter; replace if out of range.
