The Kenmore refrigerator error F-DS indicates a defrost sensor failure, which can lead to improper cooling and erratic temperature readings. This issue is often caused by a faulty freezer defrost sensor (thermistor) or wiring problems within the defrost system. Common symptoms include the F-DS error code on the control panel, frost or ice buildup on the freezer evaporator coils, and incomplete defrost cycles.

Common Symptoms:

  • Error code F dS displayed on control panel
  • Frost or ice buildup on freezer evaporator coils
  • Defrost cycle not completing properly

Possible Causes

  • Faulty freezer defrost sensor (thermistor) (medium)
  • Wiring issues between defrost sensor and control board (medium)
