What Does Error HS Mean?

The LG refrigerator HS error code indicates a humidity sensor issue, typically caused by a short or open circuit. This can lead to erratic temperature and humidity control, often accompanied by unusual humming sounds and a warm interior. Inspect the humidity sensor and wiring for potential issues to resolve the problem.

Common Symptoms:

  • HS code displayed on refrigerator panel
  • Possible erratic temperature or humidity control behavior
  • Potential defrost or humidity-related cycle issues reported by community sources

Possible Causes

  • Humidity sensor short or open circuit (medium)
  • Moisture intrusion or connector issue at humidity sensor (low)
  • Faulty main control board interpreting humidity sensor signal (low)

How to Fix Error HS

DIY Fix Basic inspection and reset

  1. Record the error code displayed.
  2. Unplug the refrigerator from power for a few minutes to attempt a reset.
  3. Plug the unit back in and check if the HS code returns.

Technician Only Check humidity sensor and wiring

  1. Unplug the refrigerator and locate the humidity sensor (often near air duct or control housing).
  2. Inspect the humidity sensor connector for corrosion, moisture, or loose connections.
  3. Test the humidity sensor circuit with a multimeter for open/short conditions.
  4. Replace the humidity sensor if it fails tests.
  5. If sensor and wiring are good but error persists, test the main control board logic related to humidity sensor input.

Parts needed: Humidity sensor assembly, Wiring harness, Main control board (if required)

🛑 When to Call a Pro:
