Whirlpool Dryer Error Code F:29

F:29 means the dryer's moisture sensor strip circuit has detected a short circuit. The moisture sensor bars are located inside the drum and measure conductivity to determine how wet the load is. This code only appears during the dryer's diagnostic test mode, not during a standard drying cycle. A technician must run the diagnostic sequence to bring up this fault.

Because F:29 only appears in diagnostic test mode and not during normal operation, your dryer may still run cycles. However, a shorted moisture sensor means the dryer cannot accurately detect when clothes are dry, which could lead to over-drying, increased energy use, or excessive heat. It is best to address the fault before relying on the dryer for regular use.

Resetting the dryer by unplugging it will not permanently clear F:29 because the code only surfaces during diagnostic test mode in the first place. The fault will reappear the next time diagnostics are run if the underlying short circuit has not been repaired. The correct approach is to diagnose and fix the sensor circuit as outlined in Test 5 of the diagnostic procedure.

Some causes of F:29 are DIY-friendly. Cleaning the sensor bars inside the drum with rubbing alcohol is a good first step and requires no parts or special tools. Inspecting the wiring harness for obvious damage is also within reach for a careful DIYer. However, replacing the sensor strip or the control board involves disassembling the dryer and working near electrical components, which is better suited to someone with appliance repair experience.

If the fix is simply cleaning the sensor bars, the cost is minimal, just rubbing alcohol and a few minutes of time. A replacement moisture sensor strip typically runs in the range of $15 to $50 for parts. If the wiring harness or control board needs replacement, total repair costs including labor can range from $100 to $300 or more depending on your location and the specific parts required.
