  • Defective humidity sensor (medium)
  • Wiring issues (short or open circuit) related to the humidity sensor (medium)

How to Fix Error ER-HS

DIY Fix Perform basic visual inspection

  1. Disconnect the refrigerator from power (unplug or switch off breaker).
  2. Inspect the humidity sensor location for visible debris, moisture, or damage.
  3. Check and ensure sensor wiring connectors are firmly seated.

Technician Only Diagnostic and component replacement

  1. Disconnect power and access humidity sensor according to the service manual.
  2. Use a multimeter to measure sensor resistance/continuity per specification.
  3. Inspect wiring harness for shorts, opens, or corrosion.
  4. Replace the humidity sensor if readings are out of spec or connectors are damaged.
  5. If the sensor and wiring are good, test the control board sensor circuit and replace as needed.

Parts needed: Humidity sensor, Wiring harness/connector, Control board (if sensor circuit failure)

🛑 When to Call a Pro:
  • If the error persists after basic visual inspection and power cycling.
  • If you are not comfortable working with electrical components inside the refrigerator.
  • If diagnostic testing of the sensor and wiring is inconclusive or indicates control board involvement.
