F29 — Moisture Sensor Shorted

The control sees the moisture sensor strips reading a very low resistance — a shorted condition. (The open-circuit condition on this sensor is the separate code F28.) Auto-sensing cycles can't determine load dryness.

Keep using it?
Yes, with caution

How to fix it

  1. Unplug the dryer and remove the front panel/toe kick to access the moisture sensor strips (usually on the front bulkhead).
  2. Clean the sensor strips with rubbing alcohol — built-up lint, minerals, or dryer-sheet residue is the most common cause of a shorted reading.
  3. Inspect the wiring from the sensor strips to the ACU for chafed insulation touching bare metal.
  4. Measure sensor resistance with the strips clean and isolated — a very low reading indicates a failed sensor; replace it.
  5. Repair any wiring found shorting to ground.
  6. Reassemble and run an auto-dry cycle to verify.

Why it happens

Typical signs: F29 displayed · Auto cycles run for the minimum time only, or end very early · Clothes may come out wet because the control thinks the load is already dry · Sensing light behaves abnormally

  • Shorted moisture sensor strips Metal sensor bars bridged by lint, mineral buildup, or fabric-softener residue create a low-resistance short.
  • Damaged sensor wiring touching bare metal Chafed insulation lets the sensor wire contact the cabinet or drum, shorting the circuit.
  • Moisture or corrosion at the sensor connector Condensation shorts the push-on terminals.
  • ACU sensing input failed Rare.

Frequently asked questions

What does the F29 code mean on a Maytag dryer?

The control sees the moisture sensor strips reading a very low resistance — a shorted condition. (The open-circuit condition on this sensor is the separate code F28.) Auto-sensing cycles can't determine load dryness.

What causes the F29 code on a Maytag dryer?

Shorted moisture sensor strips: Metal sensor bars bridged by lint, mineral buildup, or fabric-softener residue create a low-resistance short. Damaged sensor wiring touching bare metal: Chafed insulation lets the sensor wire contact the cabinet or drum, shorting the circuit. Moisture or corrosion at the sensor connector: Condensation shorts the push-on terminals.

Is it safe to keep using a Maytag dryer with a F29 error?

Yes, with caution. This is rated a moderate-severity fault.

How do I fix F29 on a Maytag dryer?

Unplug the dryer and remove the front panel/toe kick to access the moisture sensor strips (usually on the front bulkhead). Clean the sensor strips with rubbing alcohol — built-up lint, minerals, or dryer-sheet residue is the most common cause of a shorted reading. Inspect the wiring from the sensor strips to the ACU for chafed insulation touching bare metal.
