What Does Error HS Mean?

The LG dryer HS error indicates a malfunction in the humidity sensor, which can lead to improper heating or inconsistent drying cycles. This error typically appears during the start of a cycle or while drying, resulting in extended drying times or incomplete drying. The problem may stem from a faulty humidity sensor, debris obstructing the sensor, poor airflow due to vent blockages, or damaged wiring. Addressing these issues promptly can restore proper dryer function.

Common Symptoms:

  • Dryer displays HS during or at start of cycle
  • Drying cycles take unusually long or appear not to dry
  • Error may persist until sensor issue resolved

Possible Causes

  • Faulty or malfunctioning humidity sensor (medium)
  • Sensor obstruction or lint/debris buildup around humidity sensor (medium)
  • Poor airflow affecting moisture detection (vent or duct blockage) (medium)
  • Loose or damaged wiring to humidity sensor or control board (medium)

How to Fix Error HS

DIY Fix Clean and inspect humidity sensor and airflow

  1. Unplug dryer from power
  2. Locate humidity (moisture) sensor (typically near lint filter)
  3. Clean sensor gently with soft cloth to remove lint/debris
  4. Ensure lint filter is clean and reinstall
  5. Check external vent and duct for blockages, clear if needed
  6. Allow sensor area to dry fully before restarting dryer

Technician Only Check sensor function and wiring, replace if needed

  1. Disconnect power and access humidity sensor wiring harness
  2. Test sensor continuity/resistance per manufacturer specs
  3. Inspect wiring and connections for damage or looseness
  4. Replace sensor if defective
  5. If sensor tests OK but HS persists, test control board moisture detection circuits

Parts needed: Humidity/moisture sensor, Wiring harness connectors

🛑 When to Call a Pro:
  • If error persists after cleaning and basic inspection
  • If wiring or control board diagnosis is required
