This sensor harness connects the dryer's moisture sensor bars to the main wiring, helping the control or timer read moisture levels so Auto Dry cycles can advance and deliver consistent, reliable drying performance.

  • Provides the electrical path between the moisture sensor bars and the control/timer
  • Enables the dryer to sense wet fabrics and adjust or advance Auto Dry cycles
  • A damaged or open harness can cause Auto Dry to not advance, run too long, or stop early
  • Contribute to inconsistent dry times or a "Sensing" indicator that behaves abnormally
What's included: One sensor wire harness Install notes:
  • Disconnect power before servicing
  • Access the sensor bars at the front bulkhead; note wire routing and clip locations
  • Transfer routing/clips from the old harness; connect to both sensor bars and the main harness plug, ensuring snug terminals and clear wire paths
  • Restore power and run an Auto Dry test; inspect/clean the sensor bars and check harness continuity

Answer

Hi Amanda. Moisture sensor test: Open the door and locate two metal strips on the inside of the dryer (on the lint filter intake). Bridge these strips with a wet cloth or a finger. If a continuous beep is heard and an alphanumeric number is displayed on the console then the sensor is OK. If not,or if a continuous beep tone is heard before bridging the moisture strips, go top step #5. It will be advantageous to find the supplied tech sheet inside the cabinet to aid you in the diagnosis. It allows you to put the unit in a diagnostic mode which brings up fault codes and tells you which circuit needs assistance.Make sure the vent is entirely clear and not restricted. Make sure the outside vent cap / hood is opening and closing properly 4-5x /yr. so lint and moisture does not back up and create a restriction causing these issues. The sensor wiring harness is part # WP3406653. Thank You.
