What Does Error DS Mean?

The LG refrigerator error code DS indicates a defrost sensor failure, typically caused by an open or shorted defrost temperature sensor. This issue can lead to inadequate cooling, frost buildup on evaporator coils, and the error code appearing on the display panel. In dual-evaporator models, variants like 'F dS' and 'r dS' specify issues with the freezer or refrigerator defrost sensors. Proper diagnostics and repairs are crucial to restore optimal functioning.

Common Symptoms:

  • Error code displayed on panel (dS)
  • Frost/ice buildup on evaporator coils
  • Poor cooling performance / continuous running

Possible Causes

  • Defrost temperature sensor (defrost thermistor) open, shorted, or faulty (high)
  • Wiring issue between defrost sensor and control board (medium)
  • Main control board failure affecting sensor circuit (medium)

How to Fix Error DS

DIY Fix Basic checks and preliminary reset

  1. Ensure the refrigerator is powered and doors are closed properly
  2. Unplug the refrigerator for 5–10 minutes to reset the internal control board and clear temporary faults
  3. Observe if the dS code reappears after power restoration

Technician Only Inspect and replace defrost sensor/thermistor

  1. Disconnect power to the refrigerator
  2. Remove the interior panel to access the evaporator and locate the defrost sensor
  3. Inspect the sensor and wiring for continuity and correct installation
  4. Replace the defrost sensor if it is open, shorted, or out of specification
  5. Reassemble and test to confirm the error no longer occurs

Parts needed: Defrost temperature sensor (thermistor), Potential replacement wiring harness

Technician Only Check wiring and control board

  1. Verify continuity and integrity of wiring from the defrost sensor to the main control board
  2. Repair or replace damaged wiring/connectors
  3. Test the main control board if sensor and wiring are good; replace board if it fails diagnostics

Parts needed: Wiring harness and connectors, Main control board (if needed)

🛑 When to Call a Pro:
  • If the error persists after basic resetting and visible sensor inspection
  • If you are uncomfortable accessing internal components or testing electrical parts
  • If the main control board needs evaluation or replacement
