Kenmore Dryer Error Code HS

The HS code on a Kenmore dryer indicates a humidity sensor failure. The humidity sensor monitors moisture levels inside the drum to control automatic drying cycles. When the control board cannot receive a valid reading from this sensor, it displays the HS fault code and may interrupt normal operation.

A reset may temporarily clear the HS code, but if the underlying issue is not addressed, the error will return. To reset, unplug the dryer for a few minutes and then restore power. The code is likely to reappear during the next cycle if the sensor, wiring, or board problem has not been corrected.

If only cleaning the sensor bars is needed, the repair costs nothing beyond some rubbing alcohol. Replacing the humidity sensor itself typically costs between $15 and $60 for the part, plus labor if a technician is hired. If the control board is at fault, parts and labor costs can range from $150 to $350 or more depending on the model and service rates in your area.

In many cases, yes. Start by cleaning the moisture sensor bars inside the drum with rubbing alcohol, as residue buildup is the most common cause of this fault. If cleaning does not resolve the error, check the wiring harness connections at the sensor. Replacing a faulty sensor is a moderate DIY repair, but if the control board is involved, professional service is recommended.

The dryer may still run on timed dry cycles even with the HS error present, but auto-sensing cycles will not function reliably. There is no immediate safety hazard from the sensor fault itself, but running a dryer without proper moisture sensing can lead to over-drying clothes or the dryer not stopping at the right time. It is best to address the fault before continued regular use.
