What Does Error Code F29 Mean on a Whirlpool Dryer?

Moisture sensor bar failure — secondary sensor.

F29 fires when the control board reads the resistance across the secondary moisture sensor bars and gets an implausible or out-of-range value, so auto-dry cycles lose their reference for wetness and either shut off with damp loads or run excessively long. Fabric softener and dryer-sheet residue insulating the metal bars is the usual trigger. It differs from F28, which flags the primary sensor, and from F31, a broader sensor-circuit fault.

Models affected: Whirlpool electric and gas dryers with electronic auto-dry moisture sensing, including models such as WED4815EW, WED5620HW, WED6620HW, and WGD4815EW
What owners report: Owners commonly report this appearing after frequent use of dryer sheets or liquid softener, and note that loads finishing damp is often the first clue. A quick wipe of both bar sets with rubbing alcohol reportedly clears it in many cases before any part is needed.
