Maytag Dryer Error Code F29 — Moisture Sensor Failure
What this means
The F29 error code indicates the dryer's moisture sensor is failing to provide accurate readings. The moisture sensor consists of two metal bars inside the drum that detect the dampness level of clothes to determine when the load is dry. When the sensor fails, the dryer may stop prematurely or run indefinitely on auto-dry cycles.
Alternate codes: F-29
Step-by-step fix
4 stepsClean the moisture sensor bars
Locate the two metal sensor bars inside the dryer drum, usually near the lint screen opening. Clean them with rubbing alcohol and a soft cloth to remove dryer sheet residue.
Dryer sheet residue is the most common cause of moisture sensor problems.
Run a test cycle
After cleaning the sensors, run an auto-dry cycle with a small damp load. If the dryer stops at the correct dryness level, the sensors were just dirty.
Switch from dryer sheets to dryer balls to prevent future residue buildup.
Test sensor resistance
If cleaning does not help, access the back of the sensor bars and test the wiring. Check continuity from each sensor bar to its connection at the control board.
The sensor bars themselves rarely fail — wiring connections are the more common issue.
Replace the moisture sensor
If the sensor bars are damaged or wiring is broken, replace the moisture sensor assembly. Remove the mounting screws and disconnect the wire harness.
The sensor is a simple snap-in or screw-in part.
When to call a professional
If the error persists after cleaning and replacing the sensor, the main control board may not be reading the sensor correctly, requiring professional diagnosis.
