Kenmore Dryer Error Code F-29

F-29 indicates that the moisture sensor strip has shorted, as detected during the dryer's diagnostic test mode. The moisture sensor is responsible for measuring how wet your clothes are so the dryer knows when to stop automatically. This code does not appear during normal operation and will only surface if you run the built-in self-test. Diagnosis should start with the TEST #5 procedure to identify the exact source of the short.

The F-29 code only appears in diagnostic test mode and not during normal drying cycles, so the dryer may still run. However, a shorted moisture sensor means the automatic drying cycles may not function correctly, potentially causing the dryer to run longer than intended. Running the dryer with a known sensor fault for extended periods can waste energy and could stress other components. It is best to diagnose and resolve the issue before continued heavy use.

Repair costs depend on the failed component. Cleaning the sensor bars costs nothing beyond a few minutes and some rubbing alcohol. Replacing a moisture sensor strip typically runs between $20 and $60 for the part, while a new wiring harness can range from $30 to $80. If the control board is at fault, parts alone can range from $100 to $250 or more, and adding labor costs for a service call will increase the total significantly.

Some causes of F-29 are DIY-friendly, such as cleaning residue off the sensor bars inside the drum with rubbing alcohol. However, diagnosing a short in the wiring harness or sensor strip requires a multimeter and comfort working with electrical components. If the fault is in the control board or deep in the wiring, a qualified technician is recommended to avoid misdiagnosis and unnecessary part replacement.

Resetting the dryer by unplugging it or cutting power will clear the code from the display, but it will not resolve the underlying short circuit in the sensor system. The code will return the next time a diagnostic test is run if the fault has not been repaired. A proper fix requires identifying and correcting the actual cause, whether that is a dirty sensor, damaged wiring, or a failed component.
