LG Dryer HS Error Code

LG directs users to clean and fully dry the accessible sensor surfaces before trying another cycle. The source does not identify a specific underlying component failure.

Applies to LG dryer with humidity sensor

What the appliance detected

Detected condition

The dryer detected an error involving the humidity sensor.

What may contribute

Possible causes

  • The reviewed LG page does not identify a specific underlying cause; its supported preliminary step is cleaning the accessible humidity-sensor surfaces.

Start conservatively

Safe preliminary checks

Work in order and stop whenever a step is not supported by the documentation for your model.

  1. Record the code and exact model

    • Photograph or write down HS before changing anything.
    • Confirm the full model number and owner manual so the accessible humidity-sensor location is identified correctly.

  2. Let the dryer stop and cool

    • Turn the dryer off, wait for the drum to stop completely, and allow hot surfaces to cool before reaching into the drum opening.
    • Stop for smoke, a burning odor, sparking, unusual heat, or visible damage.

  3. Clean only the accessible sensor surfaces

    • If the owner manual confirms the accessible sensors below the lint filter, wipe their surfaces with a damp rag or paper towel as LG directs.
    • Do not remove covers or sensor parts, and do not use the dryer until the surfaces are fully dry.

  4. Try one normal cycle

    • After the sensor surfaces are fully dry and everything is reinstalled normally, try another supported cycle.
    • If HS persists, stop and request appliance service.

Actions not recommended

  • Do not remove the humidity sensor, open panels, disassemble the dryer, or access internal wiring.
  • Do not use abrasive tools or operate the dryer while the sensor surfaces remain wet.
  • Do not treat HS as proof that the sensor must be replaced.

When to stop and request service

  • Request appliance service if HS persists after the accessible sensor surfaces have been cleaned and fully dried.
  • Stop if the model documentation does not identify a homeowner-accessible sensor surface or any disassembly would be required.
  • Stop immediately for smoke, burning odor, sparking, unusual heat, or visible damage.
