✅ Cross Reference Information

Current Part Number6615JB2005S

Common Symptoms

  • Refrigerator does not complete or enter its normal automatic defrost cycle
  • Fresh-food compartment becomes warm while the freezer may remain cold
  • Evaporator coil develops abnormal frost or ice buildup
  • Defrost-related error indication may appear
  • Cooling efficiency may decrease and run time may increase

Check Before Replacing

  • Disconnect refrigerator power before accessing the sensor assembly or wiring.
  • Visually inspect the evaporator area for abnormal frost buildup and inspect the assembly for visible damage, loose connectors, or damaged wiring.
  • Verify that the sensor assembly is positioned against the evaporator area as designed and that its harness is not pinched or displaced.
  • If service documentation for the specific refrigerator model provides resistance specifications, check sensor continuity/resistance with power disconnected; do not use this check alone to confirm the part is defective.
  • Check the defrost heater, fuse, wiring, and control system separately before attributing a defrost failure to this assembly.

Pro Tip

Heavy frost does not prove the sensor is defective; the defrost heater, fuse, wiring, control board, airflow, and sealed-system conditions can produce similar symptoms.
