Genuine Whirlpool OEM dryer moisture sensor bar/electrode that detects the amount of moisture in the laundry load for automatic drying-cycle control.

Is This the Right Part?

✅ Cross Reference Information

Common Symptoms

• Clothes remain damp when an automatic cycle ends prematurely.
• The dryer runs unusually long or does not stop during an automatic cycle.
• The sensing cycle may behave inconsistently when the sensor bars are coated with residue, corroded, damaged, or disconnected.

Check Before Replacing

• Unplug the dryer before inspection or service.
• Inspect the sensor bar and surrounding outlet-screen grille for lint, fabric-softener residue, corrosion, cracks, or physical damage.
• Clean visible residue from the sensor surfaces using the dryer manufacturer's approved cleaning method, then retest an automatic cycle.
• Visually inspect the moisture-sensor wire harness and terminals for loose, disconnected, damaged, or corroded connections.
• Compare operation on an automatic moisture-sensing cycle with a timed-dry cycle; abnormal behavior limited to automatic cycles supports checking the moisture-sensing system, but does not by itself identify the failed component.
