What Does Error R-DS Mean?

The Kenmore refrigerator error code R-DS indicates a malfunction in the defrost sensor, which may lead to improper defrost cycles and frost buildup. This error typically arises from a faulty defrost thermistor or issues with the wiring harness. Users may notice unusual sounds or inconsistent cooling when this error occurs.

Common Symptoms:

  • Error code R-DS displayed on refrigerator panel when diagnostic system detects sensor issue.
  • Possible improper defrost cycle or frost buildup in the refrigerator compartment if sensor is not reporting correctly.

Possible Causes

  • Faulty refrigerator defrost sensor/thermistor (medium)
  • Wiring harness or connector issue related to the defrost sensor circuit (medium)

How to Fix Error R-DS

DIY Fix Basic inspection of sensor area and wiring

  1. Unplug the refrigerator or turn off power at the breaker.
  2. Locate the defrost sensor in the refrigerator compartment (often on or near the evaporator coil).
  3. Visually inspect sensor wiring and connectors for loose, damaged, or frayed wires.
  4. Ensure connectors are seated securely.

Technician Only Test and replace defrost sensor or repair wiring as needed

  1. Use a multimeter to measure the defrost sensor’s resistance at various temperatures to verify proper operation.
  2. Inspect the wiring harness for continuity and no shorts.
  3. Replace the sensor with a manufacturer‑specified part if readings are out of range.
  4. Repair or replace damaged wiring or connectors.

Parts needed: Defrost sensor/thermistor, Wiring harness/connectors

🛑 When to Call a Pro:
  • If the error persists after verifying sensor and wiring connections.
  • If testing shows the sensor reads within normal range but the error remains.
  • If there is frost buildup suggesting deeper defrost system failure.
