What HS means
Humidity sensor error — the dryer may run a very long cycle until the sensors are cleaned.
Likely causes
Residue on the sensor bars below the lint filter fools the dryer into a long cycle.
Check: Wipe the two metal sensor bars inside the drum with a damp cloth, let them dry, then retry.
Est. cost: $0–$0
If cleaning the bars does not help, the sensor harness or bars may have failed.
Check: After wiping the bars, run a timed dry cycle. If HS returns immediately, schedule service.
Est. cost: $0–$120
