Humidity sensor failure

Also displayed as: HS

How to Fix

1. 1

   Turn off the dryer.

2. 2

   Call for service.

3. 3

   Technician: inspect moisture sensor bars in lint filter housing for corrosion, damage, or debris.

4. 4

   Disconnect NA6 connector from main PCB; measure resistance between NA6-(GN) pin and chassis ground — should be less than 1 Ω.

5. 5

   If greater than 1 Ω: check wiring harness connections and ground screws.

6. 6

   Place jumper between NA6-(OR) and NA6-(BL); measure resistance between moisture sensor bars inside drum — should be less than 1 Ω.

7. 7

   Check all sensor harness connectors for corrosion, loose or bent pins, and broken wires.

8. 8

   If wiring is intact and sensor bars are clean but fault persists: replace main PCB.
