Maytag Dryer F24 — Inlet Thermistor Fault

Maytag Dryer · Error code F24

What F24 Means

The inlet thermistor (near the heat source) is reading out of range — open, shorted, or drifted. Temperature control is compromised.

Symptoms

  • F24 on display
  • No heat or weak heat
  • Dryer stops early
  • Long dry times

Common Causes

1
Failed inlet thermistor

Component drift or failure.

2
Wiring fault to inlet thermistor

Pinched, chafed, or loose connection.

3
Damaged by overheat event

Restricted airflow caused thermistor damage.

4
ACU input circuit failure

Rare board-level fault.

How to Fix It

  1. Unplug the dryer and access the heater assembly (typically requires removing the back panel on electric models or the front/toe panel on gas).
  2. Locate the inlet thermistor near the heater inlet.
  3. Measure resistance and compare against the tech sheet (around 10 kΩ at 77°F).
  4. Replace if out of spec or open.
  5. Inspect and clean the lint screen housing and vent — overheat events are usually airflow related.
  6. Reassemble and run a heated cycle to verify the fault clears.
