Error Code HS

Humidity sensor failure

Also displayed as: HS

How to Fix

1. 1

   Turn off the dryer.

2. 2

   Inspect moisture sensor bars inside lint filter housing for contamination or damage.

3. 3

   Check wiring harness between sensor bars and main PCB (connector WH6) for damage.

4. 4

   Measure resistance between WH6 (GN) pin and chassis ground; should be less than 1Ω.

5. 5

   Disconnect WH6 connector from main PCB; jumper WH6 pin (OR) to WH6 pin (BL).

6. 6

   Measure resistance between the two sensor bars; should be less than 1Ω with jumper in place.

7. 7

   If not, check all connections and wires between WH6 terminal at main PCB and sensor bars.

8. 8

   If wiring is intact but fault persists, call for service.
