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
- Unplug dryer from power
- Locate humidity (moisture) sensor (typically near lint filter)
- Clean sensor gently with soft cloth to remove lint/debris
- Ensure lint filter is clean and reinstall
- Check external vent and duct for blockages, clear if needed
- Allow sensor area to dry fully before restarting dryer
Technician Only Check sensor function and wiring, replace if needed
- Disconnect power and access humidity sensor wiring harness
- Test sensor continuity/resistance per manufacturer specs
- Inspect wiring and connections for damage or looseness
- Replace sensor if defective
- If sensor tests OK but HS persists, test control board moisture detection circuits
Parts needed: Humidity/moisture sensor, Wiring harness connectors
- If error persists after cleaning and basic inspection
- If wiring or control board diagnosis is required
