What Does Error F29 Mean?

The Whirlpool dryer F29 error indicates a moisture sensor fault, where the internal diagnostics detect abnormal moisture sensor resistance. This can prevent the dryer from starting or cause erratic behavior. The moisture levels may be misreported, leading to ineffective drying. Common causes include a short or low resistance in the moisture sensor, damaged wiring, or a fault in the control board. Basic troubleshooting can involve a power reset and cleaning the moisture sensor strips.

Common Symptoms:

  • F29 appears on display and dryer may stop or refuse to start normal cycles after detection
  • Moisture levels may be misreported, potentially leading to improper drying
  • Code persists after simple power cycle

Possible Causes

  • Moisture sensor short or low resistance (high)
  • Loose or damaged wiring between moisture sensor and control board (medium)
  • Control board fault affecting sensor circuit (medium)

How to Fix Error F29

DIY Fix Power reset and basic checks

  1. Turn off dryer and disconnect power at the breaker or unplug for 5 minutes
  2. Reconnect power and run a short cycle to see if F29 returns
  3. Clean lint trap and ensure moisture sensor strips (near lint trap area) are clean of residue/debris

Technician Only Inspect and service moisture sensor circuit

  1. Disconnect power and access moisture sensor inside dryer (typically near lint trap opening or drum interior walls)
  2. Visually inspect wiring harness and connectors for damage or looseness
  3. Test moisture sensor resistance with a multimeter to confirm short/low resistance
  4. Replace moisture sensor if defective
  5. Verify wiring and replace or repair if damaged
  6. If sensor and wiring are good but code persists, test control board sensor circuit and replace PCB if faulty

Parts needed: moisture sensor, wiring harness/connectors, main control board (if needed)

🛑 When to Call a Pro:
  • If the error persists after basic cleaning and power reset
  • If you are not comfortable accessing internal components safely
  • If testing indicates board-level faults
