LG Error Code HS
Humidity sensor error
Common Causes
- 1Sensor failure
Step-by-Step Troubleshooting
- 1
Locate the humidity sensor bars inside the dryer drum — they are two metal strips mounted on the front bulkhead that clothes contact during tumbling
- 2
Clean the sensor bars with a cloth dampened with rubbing alcohol to remove dryer sheet film and fabric softener residue — this is the most common cause of HS on LG dryers
- 3
If cleaning does not resolve the error, check the sensor wire connections at the front bulkhead — vibration can loosen the spade connectors
- 4
Test sensor bar resistance — when dry, resistance between the bars should be open (infinite); when touched with damp cloth, resistance should drop to under 100k ohms
- 5
If the sensor tests OK, the main board ADC input for the humidity sensor may have failed
Pro Diagnostic Tip
Fabric softener and dryer sheets leave a waxy film on the humidity sensor bars over time. This film insulates the bars from moisture contact, making the dryer think clothes are dry when they are still damp. Switch to liquid fabric softener in the wash cycle instead of dryer sheets to reduce buildup.
